COVID Study Implicates Restaurants
CDC: Dining-in Poses Risk
The US Centers for Disease Control and Prevention (CDC) finds that adults with COVID-19 are about “twice as likely” to say they have dined at a restaurant during the 14 days before testing positive for the disease.
The study, which was limited to those experiencing symptoms, examined 314 adults at 11 different health care facilities in 10 states. Half (154) tested positive, and 160 tested negative for COVID-19.
Those who tested positive “were approximately twice as likely to have reported dining at a restaurant than were those with negative SARS-CoV-2 test results,” according to the study. As a result, researchers recommend that “efforts to reduce possible exposures where mask use and social distancing are difficult to maintain, such as when eating and drinking, should be considered to protect customers, employees, and communities.”
“Adults with confirmed COVID-19 (case-patients) were approximately twice as likely as were control-participants to have reported dining at a restaurant in the 14 days before becoming ill,” according to the CDC. “In addition to dining at a restaurant, case-patients were more likely to report going to a bar/coffee shop,” according to the report released Sept. 11.
“Reports of exposures in restaurants have been linked to air circulation. Direction, ventilation, and intensity of airflow might affect virus transmission, even if social distancing measures and mask use are implemented according to current guidance. Masks cannot be effectively worn while eating and drinking, whereas shopping and numerous other indoor activities do not preclude mask use,” according to the study.
Researchers report that 71% of the COVID-19 positive patients said they work masks in public; 74% of those who tested negative said they always wore face coverings in public.
“In this investigation, participants with and without COVID-19 reported generally similar community exposures, with the exception of going to locations with on-site eating and drinking options,” writes CDC.
Forty-two percent of those who tested positive reported having close contact with at least one person known to have COVID-19, most often family members.
The study mentions five limitations, including small sample size and the fact that participants were aware of their test results. “Of note, the question assessing dining at a restaurant did not distinguish between indoor and outdoor options,” according to researchers, who say additional research is warranted but caution that “eating and drinking on-site at locations might be important risk factors associated with SARS-CoV-2 infection.”
Billy Corgan Resurrects Madame ZuZu’s Tea Emporium
Two years after closing, and in the middle of serious viral spread in Chicago, Billy Corgan is bringing back Madame ZuZu’s Tea Emporium on First Street in Highland Park.
Singer and song writer Corgan, who founded the Grammy-Award winning Smashing Pumpkins, promises “to carry on ZuZu’s tradition of a whimsical atmosphere but in a larger, Art Deco space reminiscent of a 1930’s tea salon.”
Partner Chloe Mendel told Eater Chicago that she and Corgan are sourcing from the Rare Tea Cellar, a local gourmet tea supplier with a global reputation. In addition to superior teas, the cellar offers $195 olive oil and bottled mixes like Umami Shrubbery and Forbidden Forest Lapsang Souchong Syrup.
The avante-garde vegan menu expands on the original, featuring $10.25 salads such as kale power salad, Chinoise crunch and Salad Niçoise. Chloe’s tomato soup is $4.95 a cup and sandwiches sell for $8 to $12. Specialties include grilled vegan cheese and vegan Gado Gado tofu bowl and a miso bowl with pickled veggies and coconut rice.
“I quickly learned that the delicious world of plants is so overlooked,”says Mendel, who crafted several plant-based dishes.s here
Iced tea sells for $3 a glass and a Korean Blue Elektra Matcha is priced at $4.50. There is a Reishi cappuccino and a Lionsmane Mushroom Coffee ($5) on the drink menu. The rare teas are about double these prices.
“Our business model is simple: healthy living combined with an open source venue for the arts, where everyone in our community can gather and share,” writes Corgan, who opened the first location in 2012.
At the time he told Crave Magazine, “I’m a tea guy and living in Highland Park since 2003. I’ve always wanted to open a salon like this for everyone to enjoy,” Corgan told Crave Online. “This is a place with no age boundaries. We hope to attract everyone from young students to seniors. With a blend of music, photo galleries, art displays and speakers, I think Madame ZuZu’s offers something for everyone.”
There will be no impromptu concerts for now. The shop operates under COVID-19 restraints limiting dining-in, so take-out is a good option. Staff are tested for COVID-19 daily, writes Corgan.
Amid hundreds of store closings, a steady trickle of new tea shops and cafes are re-opening. Eater Chicago lists Sawada Coffee, the Living Water Tea House and El (evated) Ideas, a Michelin-starred restaurant. Keep in mind that while tea shops sell a tiny fraction of the total volume on offer, places like Madame ZuZus influence conventional tea drinkers to give specialty teas a try.
Unilever Divestiture Worries Plantation Workers
The announced divestiture of tea holdings by the world’s largest tea supplier makes uncertain the fate of the company’s wholly owned tea gardens and hundreds of smaller gardens under contract.
In July, following a strategic review begun in January, London-based Unilever said it will break up its tea business, retaining only bottling partnerships while continuing operations in India and Indonesia. The rest of the company’s tea assets, including several tea estates, will be sold at auction.
Unilever purchases 10% of the world’s tea, employing more than one million workers in 21 countries. Brands currently marketed by the company include Lipton, PG Tips, Brooke Bond, Pure Leaf, TAZO, Bushells, T2 (retail shops), and 21 smaller brands sold in more than 150 countries. Lipton Yellow Label, the world’s best-selling tea brand, accounts for 7% of black tea sales globally. Sales of green tea are insignificant when compared to Asia brands. The tea division is valued at $4-$5 billion, according to financial analysts at Barclays.
Unilever will retain the core brand in high-growth markets and divest in slow-growth regions such as Australia and Europe where the popularity of black tea is in decline, according to Allied Market Research.
In Kenya, 60,000 workers employed by Unilever Tea Kenya Ltd. anticipate a gradual scaling back of operations at the 8,700-hectare Kericho Tea Estate. Staff are uneasy, according to TheNation which reports Unilever “has not yet revealed its plans with its Kenya operations to shareholders, who have endured five years without receiving dividends owing to losses.”
In August Sylvia-ten Den, managing director at Unilever Kenya Tea Ltd. advised the Kenya Agricultural and Plantation Workers Union (KPAWU) “that the company is changing its operation model.”
“She writes that Unilever will form a new company to manage its global tea business, and that the form and shape of the new entity will be decided at the end of next year. She assures that until then operations will proceed as normal,” according to The Nation.
Unilever contracts with 30 Kenya tea estates and the Kenya Tea Development Agency (KTDA) which represents another 69 estates producing black and green tea.
In addition to Kenya, Unilever contracts with tea gardens in Malawi (21), Uganda (13), Tanzania (12), and Zimbabwe (6). It is likely that Unilever will continue to purchase tea grown in Africa but marketed under its India brands. Brooke Bond, which was acquired by Unilever, has a century-old tradition of growing tea in Africa.
The coronavirus pandemic is forcing companies to reassess their core divisions and shift focus to higher-growth areas, say bankers and mergers and acquisitions lawyers, according to MarketWatch.
“So far this year, companies globally have sold 8,895 non-core assets worth a total of $391 billion, according to financial data provider Refinitiv. That compares to 11,294 asset sales worth almost $415 billion for the same period in 2019,” writes MarketWatch.

A shortfall in domestic production amid rising demand is boosting tea prices to record highs in India.
The Tea Board of India is reporting record prices at tea auctions. In Kolkata and Guwahati (Assam) prices are up INRs100 ($1.33/kg compared to last year. The price for CTC (crush, tear, curl), which is mainly used in making tea bags, recently averaged INRs 313.58 ($4.19/kg), up INRs129.99 per kilo.
Prabhat Bezboruah, the chairman of India’s Tea Board, said that a 12% price increase might compensate for the 10% crop loss. Green leaf prices in Tamil Nadu also rose from INRs14-17 to INRs22 ($0.29) in August.
Last week marked the fourth week of price gains in Mombasa, Kenya where the East African Tea Traders Association (EATTA) reports an average Ksh208 ($1.93) compared to Ksh194 ($1.80/kg) the previous week. Unlike India, where production has declined significantly, tea production is up 41% in Kenya due to good weather but is likely to plateau for the remainder of the year. Exports to primary trading partner Pakistan are up 14% and the UK purchased 66% more Kenyan tea than usual as a result of shortages elsewhere.
In Japan, the newspaper Chunichi Shimbun reported record low prices for Kagoshima Nibancha. Sales by global tea firm Ito En, the largest tea company in Japan, decreased by 8.5% from February through April due to the coronavirus.
“Tea auctions both in Shizuoka and Kagoshima declared that the price for second harvest tea was lower compared to last year. In Shizuoka, it is estimated that the price per kilogram for summer tea went down by 10-15% from JPY609/kg in 2019. In Kagoshima, the decrease is even steeper by 26% to JPY452/kg this year,” according to the Global Japanese Tea Association.
Over the past decade, tea prices have ranged from a low of $2.19/kg in January 2009 to a high of $3.29/kg in September 2017, but the long-run average price has stood at $2.85/kg, according to the Economist Economic Unit (EIU).
“Last year tea prices fell to $2.57/kg globally, due to ample supply, marking the weakest result since 2008. Although production prospects in most major tea producers are disappointing in 2020, weaker demand growth is likely to depress prices further,” according to EIU. Prices fell to $2.33/kg in the first quarter of 2020, which marked the weakest quarterly result in 11 years. “Although they rebounded to $2.57/kg in the second quarter, they remain 3% below year-earlier levels. We expect tea prices to average $2.50/kg in 2020. Even assuming that underlying conditions improve in 2021, we expect only a moderate rise in average prices, to $2.81/kg,” writes EIU.
Sri Lanka also reports increased prices at auction with some record-setting buys, defying on first appearance the rules of supply and demand.
Controversial Import Proposal
As domestic prices surge, India is weighing the possibility of importing tea from Kenya and Vietnam. The government currently imposes a 100% tariff on tea imports which discourages imports.
If the initiative advances, The Federation of All India Tea Traders Association (FAITTA) said that importing teas will be a one-time affair and that it will not push for imports in the coming years, according to a report in the Economic Times. FAITTA wants a one-year relaxation of tea tariffs.
FAITTA chairman Viren Shah said, “Prices have gone up significantly this year due to a shortage of supply. But we are not being able to pass on the price to our customers because the economic situation in the country is not conducive to increasing prices. The pandemic has created economic uncertainty everywhere.”
The debate is heated. Tea landed in India to this point is for re-export, which is not available in domestic markets where it competes with locally grown tea. Re-exports total only 9-10 million kilos annually. Planters, represented by the India Tea Association (ITA), strongly oppose lowering tariffs even for a limited time.
“We will move the commerce ministry with a request to stop the import of cheap teas if the traders try to do so,” said Vivek Goenka, chairman, ITA.
The price of CTC tea has increased by 48% year-on-year making imports less expensive than domestic teas. Even with a 100% duty, imported Kenyan tea at $1.84 per kilo or Vietnamese tea at $1.50 per kilo would be less expensive than the average INRs305 ($4.07) per kilo paid for CTC at the Kolkata Tea Auction.
India consumers purchase 1,100 million kilos annually. Much of this tea is from Assam and West Bengal where production is down 30% during the period January-July. Ultimately imports may be unavoidable as teas from overseas would stabilize domestic prices.
Monsoons annually claim the lives of many tea workers and cause hundreds of millions in property damage. Ten days ago, 43 died in a mudslide that swept tea workers away in their sleep at the Kannan Devan Hills Plantations (KDHP) in Munnar, South India. Rescuers dug for two days but found no additional survivors amid the 20 homes that were lost. The garden employs 12,500 workers.
In Kerala, lowland floods claimed additional lives. This spring India’s tea production fell 26.4% compared to last year due to a combination of flooding and coronavirus lockdowns. Assam gardens reported serious flooding in May, June, and July which is the top tea producing month.
Indian Tea Association Secretary Sujit Patra, told Reuters that a recovery in crop totals was unlikely in the second half of the year. The shortfall has caused auction prices to rise up to a record average of IRNs232.60 ($3.12) per kilo last week, up 57% compared to the same period in 2019.
This week in Yunnan China, 14 died and 20 are still missing following flash floods caused by Typhoon Higos. Landslides killed five. The storm forced the relocation of 34,900 residents and affected 1.1 million people, causing at least $450 million in damage, according to China.Org. After an extended drought, rainfall averages are up 12.5% year-on-year. Across China 200 have died in weather-related incidents this year which have caused $25 billion in losses.
In July the Japanese island of Kyushu suffered severe flooding that damaged several tea farms. Production is down overall, in Shizuoka the normal harvest decreased by 20-30% from 7,616 metric tons in 2019, and likely will be the lowest since 1953, when the first of such data became available.
TheWorld Meteorological Organization (WMO) predicts“high latitude regions and the Sahel* are likely to be wetter than the recent past whereas northern and eastern parts of South America are likely to be dryer” during the period 2020-2024.
“Most of Eurasia, eastern USA and central Africa have been wetter than average, with southern Africa, eastern Australia, Indonesia, north-east Brazil, and western Europe drier than average,” according to WMO’s five-year forecast.
“The annual global temperature is likely to be at least 1°C warmer than pre-industrial levels (defined as the 1850-1900 average) in each of the coming 5 years and is very likely to be within the range 0.91 – 1.59°C,” according to WMO.
“The smallest temperature change is expected in the tropics and in the mid-latitudes of the Southern Hemisphere,” according to WMO, but “it is likely (~70% chance) that one or more months during the next 5 years will be at least 1.5°C warmer than pre-industrial levels.

The deadline to enter the third annual Teas of the World competition, conducted by the Agency for the Valuation of Agricultural Products (AVPA) is Sept. 15, 2020. Prizes will be awarded Nov. 16 in Paris, France
The competition is open to producers who benefit from recognition of their exceptional quality, helps producers stand out from others growing and processing tea, and encourages producers to explore new tea markets.
The competition consists of “Monovarietal teas.” a category limited to Camellia Sinensis and “Infusions” which include beverages made with plants other than Camellia Sinensis including blends and favored teas.
Judges evaluate gastronomic rather than standardized refereeing, seeking a striking rather than consensual sensory profile. “This is the first time that an independent body in a consumer country promotes the good practices of production and trade actors,” writes AVPA.
Fees are €110 for individual producers, €550 for other tea professionals and €1,500 for collective organizations.
AVPA is a non-governmental, non-profit organization of producers and enthusiasts. The organization annually conducts four international contests in addition to evaluating tea. These include “Coffees roasted at Origin”, “Chocolates pressed at Origin” and “World Edible Oils.”

Few tea ventures deployed parachutes capable of breaking the fall as the world’s economies catapulted over the second quarter cliff.
The result is the permanent closure of hundreds of high-profile tea locations in malls and tourist destinations as well as beloved Mainstreet independents like the 10-year-old Wenham Tea House in Massachusetts and 27-year-old Lucy’s Coffee & Tea in Birmingham, Ala.
The Samovar Tea Lounge’s three San Francisco locations are “hibernating” for an unspecified time and the Floating Mountain Tea House will relocate from New York’s upper west side to Croton-on-Hudson upstate. Restaurants that featured fine tea, including Augustine in New York’s Beekman hotel, Vaucluse on Park Avenue and “even the glitzy McDonald’s flagship store off Times Square closed,” according to a list maintained by Eater New York. In July DAVIDsTEA permanently shuttered 213 locations including 42 in the U.S. leaving only 18 in Canada.
The U.S. experienced a record 9.5% drop in economic output, that if left unchecked before the year ends could lead to an unprecedented 32.9% annualized decline in GDP. Europe experienced a 12.1% decline, its worst contraction on record. Canada, which has suffered many fewer infections and COVID-19 deaths than the EU and US, estimates its economic activity will decline 12%, according to Statistics Canada. Retail sales in all the Western countries signal a deep recession with several segments, including food service, plummeting from the end of March and continuing their decline through April. Retail rallies began in May except in the U.S. where a new surge of infections led to a loss of steam by July.
The descent was especially rapid and painful in the U.S. It is difficult to get precise numbers on sales of tea in retail channels. Grocery sales figures are generally good as millions of customers that purchased tea at restaurants and cafes now brew at home. Online sales spiked last spring but are flattening. The tea shop category mirrors the fate that has befallen small independently owned cafes and bars with some segments such as Sunday afternoon tea in tony hotels and at cozy Victorian tearooms located in southern tourist towns virtually annihilated.
“Afternoon tea was devastated in the U.S. in particular—most of those businesses didn’t have a way to pivot online or offer tea-to-go,” writes Abraham Rowe, founder of Sinensis Research in Washington, D.C. Rowe observes that online sales proved to be a lifesaver, “people were loyal to some local shops, and are now shopping online from them.”
“Store closures are down a bit—I don’t have final figures, but hope to run another survey sometime to finalize it,” said Rowe.
As brick and mortar sales at tea merchants slipped over the precipice, online sales increased but not uniformly. An updraft enabled Amazon to glide to the bottom with a year-over-year increase of 34% in tea sales, totaling $29 million for the 52 weeks ending in May, according to Hinge Global. Walmart generated an unexpected $4 billion during the first quarter, up 4% over the same period compared to the previous year. The company announced it intends to become a “omnichannel” business. During the past year Walmart consolidated its online and physical store operations and is focused on expanding e-commerce rather than building new stores.
Amazon and Walmart are the exceptions amid a pandemic that devastated the retail sector. While customers ordered groceries online and had food delivered, very few tea ventures had time to deploy a Plan B. DAVIDsTEA, headquartered in Montreal, Canada, in March closed 231 locations eliminating $12.1 million in second quarter sales. Sales for the three months ended May 2 declined 27.3% to $32.2 million. Wholesale and online revenue climbed $9.3 million to $17.0 million. Online sales reflect the trend identified by Rowe at Sinensis Research: specialty tea buyers online remain loyal to their local tea shop whether in a mall or downtown.
“Sales in grocery stores and pharmacies across Canada continues solid growth,” according to Frank Zitella, who is both CFO and COO at DAVIDsTEA. He wrote in a July 31 earnings report that “with first quarter sales growth of over 120% year-over-year, we are extremely pleased that our loyal tea-loving customers have shifted to buying our teas online, and in supermarkets and drugstores. The strong performance of these sales channels provided us with the confidence that we are on the right path for the future.”
Calls to wholesalers confirm that while online sales have eased the painful loss of tea house closures, declining monthly orders from restaurants and hotels resulted in orders that are no where near pre-pandemic norms. The collapse of restaurant dining, which accounts for 20% of tea sales globally, is the biggest cause. Some 2.2 million restaurants worldwide are not expected to survive through 2020. Closings have a greater impact on coffee sales in the U.S. but in tea drinking nations like the UK and Russia the shift from away-from-home to at-home preparation has been significant.
McKinsey Small Business Forecast
“In a muted recovery, it could take more than five years for the most affected sectors to get back to 2019-level contributions to GDP,” according to McKinsey & Company. Small businesses, which are hard hit due to lower margins and limited reserves, constitute 68% of the food services and accommodations sector and are not expected to recover before the first quarter 2024 stretching into 2025. Arts, entertainment and recreation sectors will take even longer, according to U.S. Small Business Recovery After the COVID-19 Crisis.
“After the 2008 recession, larger companies recovered to their pre-crisis contribution to GDP in an average of four years, while smaller ones took an average of six,” writes McKinsey Global Institute.
“Improving operations and adapting business models can help small businesses in many industries recover,” observes McKinsey, but muted demand, operational challenges due to health and safety restrictions and new customer expectations all take time: “Finding the cash to do so may be a stretch.”
Working capital is often tied up in inventory and small businesses have added cost servicing their debt. A McKinsey survey of 1000 small firms finds the cost of servicing debt averages 30% of revenue. The shift to off-premise delivery and carryout “is likely to erode profitability and increase packaging costs and hinder their ability to sell high-margin items.” McKinsey found that nearly 40% of small businesses in the restaurant sector operate at a loss or break-even.
Solutions suggested in the report involve technology and marketing.
“Independent restaurants might digitize their businesses by using aggregators to increase their visibility, reach potential diners, and outsource their delivery,” write McKinsey authors Andre Dua, Deepa Mahajan, Lucienne Oyer and Sree Ramaswamy.
“Aggregators might help by offering additional on-boarding support or spotlighting small, independent restaurants on their platforms. Some combination of public and private aid may also be necessary for small restaurants, especially offering technical and financial support they’ll need to compete with larger ones that can build contact-less solutions at scale,” according to the report.
“The crisis has exposed financial frailties that have built over time, and the next normal could impose additional burdens,” according to the authors, who add, “The survival of US small businesses across the economy will require new business models and technology solutions that few have the resources to finance.”
World Tea Hosts Virtual Summit
Organizers of the World Tea Expo this week announced a virtual summit scheduled for the second week of October.
The World Tea Conference + Expo was postponed from June 14-16 to October. It was later canceled due to restrictions on events drawing large crowds to the Colorado Convention Center, in Denver Colo.
The World Tea Virtual Summit + Resources is scheduled for October 12-14.
“The virtual summit will introduce online networking and lead generation,” according to Questex, organizers of the event. Guests include Sebastian Michaelis, head of tea at Tata Global Beverages; Peter Goggi, president of the Tea Association of the USA, and Tony Tellin, co-founder of A. Tellin Co.
The agenda of three half days offers an opportunity to “learn from peers, share ideas, network virtually and safely, and support one another as we continue the shared journey through COVID.”
The next live, in-person event is scheduled for July 14-16, 2021.
Great quantities of tea are blended in America but according to the Made in America Act, a product manufactured in the US that claims to be American made, must contain at least 50% US ingredients.
ALexology post this week discusses a class action suit “that calls out Bigelow Tea for pushing unpatriotic tea.”
The post summarizes a report by Linda Goldstein and Amy Ralph Mudge with the Washington D.C. based law firm Baker & Hostetler.
The complaint, filed in California’s Central District Court, by Kimberly Banks and Carol Cantwell, alleges that by promoting their tea as “Manufactured in the USA 100% American family owned” and “America’s classic” Bigelow violates provisions of the California Consumer Legal Remedies Act, False Advertising Law, Unfair Competition Law, and Breach of Express and Implied Warranty.
Plaintiffs allege themselves and other consumers, “purchased the Bigelow Tea products because they reasonably believed, based on the packaging and advertising, that these products are American-made. However, the products are comprised solely of foreign-sourced and processed tea.”
Had plaintiffs known the truth “they would have paid less for them or they would not have purchased them at all,” reads the complaint.
Bigelow Tea responded Friday with the following statement: “Bigelow unequivocally disputes the allegations in this California based lawsuit.”
“Every box with our statement of being “Manufactured in the USA” refers to the fact these teas are produced and distributed by one of our three Bigelow owned and operated manufacturing facilities, located in Connecticut, Kentucky, and Idaho. In addition, our packaging clearly states that our teas are “Blended and Packaged in the USA”. Bigelow continues to be open and transparent about our global sourcing of ingredients (many of which come from the United States) on both our website and the packaging of select varieties of our teas.”
“Frivolous lawsuits such as these are designed to purposefully damage the reputation and finances of the companies they target. Bigelow Tea is proud to be a 100% American family owned and operated manufacturing company and we are prepared to vigorously defend ourselves against this meritless lawsuit,” writes Bigelow.
While Bigelow owns the largest US tea farm, The Charleston Tea Garden, located in Charleston, South Carolina, the tea garden markets its tea under its own brand. The plantation website makes it clear that “Bigelow Teas are not made from any of the tea leaves grown or harvested here at the Charleston Tea Garden. Charleston Tea Garden teas are the only teas made from the tea leaves produced by the Camellia Sinensis plants grown in the fields of the Charleston Tea Garden.”
DMCC Expansion Plans
Fifteen years ago,Ahmed Bin Sulayem, executive chairman and chief executive officer of Dubai’s Multi Commodity Centre (DMCC) envisioned a tea trading hub that would service the world’s largest growing regions.
Today DMCC processes 48,000 metric tons of tea annually, accounting for 60% of global re-exports. The facility has processed 320 million kilos since its inception. The modern port facilities and airfreight capability attracted 800 new companies during the first half of 2020, said Bin Sulayem, adding that the months of May and June saw a “noticeable uptick despite an overall softer business climate.”
The tea center and atmospheric-controlled warehouse, which stores 5,000 metric tons, has a turnover of $184 million annually.
Commodity teas from 13 origins are blended for consistency and these blends, are often mixed to make herbal, floral inclusions sold as some of the world’s most popular teas. Examples include Earl Grey and the many breakfast blends distinct to markets in Ireland, Scotland, and England. Classic brands processed include Lipton and Red Rose as well as local blenders such as Tea Trading International DMCC, a Dubai-based British SME that markets brands Vertea and The Leaf to food-service catering, hotel, and resort customers.
DMCC’s tea and its new coffee center drew the attention recently of His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE, during a visit reported by Gulf Today.
“Under the guidance of His Highness Sheikh Mohammed Bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, DMCC is fast becoming the global hub for the tea and coffee industry. Our ambitious plans to triple our capacity in the near future are strategically anchored in Dubai’s drive and ability to facilitate world trade,” said Bin Sulayem.
In a release by Arjun Katyal, of McLeod Russel Middle East DMCC, said, “The DMCC’s expansion plans are incredibly exciting, and represent a huge boost to Dubai’s status as a leading global trade hub. We have been a DMCC Tea Centre member since 2011, and have seen, first-hand, the expertise, experience and vision that has shaped the success of this facility. McLeod Russel Middle East DMCC has its sights set on continued growth, and we will continue to engage new markets and reach a wider customer base than ever before. The DMCC Tea Centre has an important role to play in our success story, and we congratulate them on their latest announcement.”
Since 2005 DMCC has become one of the fastest growing free zones in the world with more than 17,000 companies conducting business in a number of sectors including precious metals, tea and coffee, and food commodities. Establishments and individuals operating in DMCC are exempt from all taxes including income tax, for a period of 50 years.
Measuring Elements in Tea
Minerals are essential to the heath of tea plants and for tea drinkers to experience the full range of tea flavor, but too much of even the best of things in life can create problems.
Researchers Dr. Ying Guo, Dr. Seungjin Lee, and Dr. Tae Lee at Georgia Gwinnett College are currently engaged in testing five commonly available tea brands using a handheld Laser Induced Breakdown Spectroscopy (LIBS) unit manufactured by SciAps. The Z-300 analyzer detects very low concentrations of mineral and potentially harmful heavy elements.
The team, whose lab work is temporarily suspended during the pandemic, detected all of the following minerals and alkali metals (Cs, K, Li, Na) in five popular tea brands. The three most common minerals were carbon, calcium, and magnesium in all five samples. Several heavy metals were also present in all five samples including Cd and Cr which are toxic in very low concentrations.
“(Before the shutdown), we obtained the spectra of tea samples and were able to qualitatively determine the elements present,” Guo says. The next step will be to calibrate and complete the quantitative analysis, she says.
Researchers pelletized tea grains from each brand and measured the intensities of emission spectra at different wavelengths to determine the presence of elements of interest in the samples. Results were validated by inductively coupled plasma mass spectroscopy.
Analyzer manufacturer SciAps notes that “minerals play an important role in maintaining the human body. For example, Ca helps with the functions of muscle contraction, enzyme activity, healthy bones and teeth, blood clotting, transmission of nerve impulses, and regulating heartbeat. K can help reduce risks for certain diseases such as stroke, kidney stones, and hypertension. Even though those are beneficial elements to the human body, there is still a suggested daily intake limit.”
The article states that “additionally, tea may be contaminated by heavy metals, “either as a result of uptake from soil or from atmospheric dispersion due to vehicular or human activities,” according to Guo. This is what led them to investigate the levels of both the beneficial minerals
(e.g., potassium and calcium) and unwanted contaminant elements (e.g., cadmium and chromium) present in different tea brands. Heavy metals can be highly toxic even at a very low concentration. LIBS was able to detect the presence of these metals in all five samples.
The following table lists the quantities of each element by relative abundance for each tea brand.
The research has not been published, but once reviewed, “By comparing with recommended daily intake limits and reference dose, we’ll be able to provide insights on daily consumption limits of tea in order to avoid too much intake of toxic elements,” says Guo.
[Editor’s Note: Tea Biz will follow up once the research is published]
Reversal Forces New Lockdowns
After flattening the COVID curve in April and May it began sloping upward in June in the U.S. while Europe continued to suppress spread of the coronavirus. July has since become the worst month on record for COVID spread with 1.9 million new infections and 1,000 deaths per day, bringing the U.S. total to 4.5 million who have tested positive. The virus is now present in populations young and old in every state with infections rising in more than half the U.S. states. Globally there are more than 18 million cases with deaths approaching 700,000. About 6% of those who have tested positive perished. On a hopeful note, 94% (11 million) have recovered. The U.S. continues to lead country totals but Brazil (2.7 million) and India (1.8 million) are hot spots. The UK, Spain, Peru and Chile experienced death rates greater than 500 per 1 million population. More than 250,000 have died with a high of 6,900 per day in April that dipped for about a month before moving seven-day average of 5,600 globally in July.
