• Hong Kong cooks up ‘clean’ lab-grown fish

  When chef Eddy Leung was tasked with cooking what was touted as the world’s first lab-grown fish fillets in his kitchen in Hong Kong, he pan-fried some and deep-fried others before finally deciding on breaded fish burgers with tartare sauce.

  “Before I cooked the fish it was quite firm, but after I cooked it, the texture changed to being like real fish,” Leung said of the culinary experiment that took place in the gritty Wong Chuk Hang neighborhood late last year.

  The fillets tasted and smelled like normal fish, but with the consistency of crab cakes, he said.

  Made by Hong Kong-based food tech start-up Avant Meats Co Ltd, the fish on Leung’s stove represents a key step toward meeting growing global demand for meat and seafood without jeopardizing climate goals, said Elaine Siu (蕭凱怡), managing director of the nonprofit Good Food Institute Asia-Pacific.

  “Cultivated meat gives consumers the animal protein they want without having to deplete the oceans or chop down the rainforest to get it,” she said.

  The fish tasting came on the heels of Singapore’s announcement early last month that it had become the first government to approve cell-cultivated chicken, leading to the world’s first commercial sale of lab-grown meat, also known as “clean meat.”

  In a report published last year, the Good Food Institute said that economic growth and rising incomes are expected to drive up Asia’s appetite for traditional meat and seafood nearly 80 percent by 2050.

  While lab-grown meat is just beginning to gain ground, a University of Oxford study in 2011 found that cultured meat could lower energy use in meat production by up to 45 percent, greenhouse gases by more than 78 percent, land use by 99 percent and water use by up to 96 percent.

  However, other researchers have said the green benefits of cultured meat are overestimated, not least because it can be energy intensive to produce.

  ‘SHRINK THE FOOTPRINT’

  Cultivating fish in a lab can be done in a fraction of the time it takes to produce fish normally, Avant cofounder and chief executive officer Carrie Chan (陳解頤) said.

  Most farmed fish take between a year to two years to grow, depending on the species, while wild fish take longer, she said.

  However, for Leung’s tasting Avant cultivated about 10 fillets in approximately two months.

  To make the fillets, the company put cells from a grouper fish into a bioreactor and fed them glucose, minerals, amino acids, vitamins and proteins — much like making beer or yoghurt, Avant cofounder and chief scientific officer Mario Chin (錢寶生) said.

  The cells then grew into muscle tissue — without heads, fins or organs.

  Cell culture technologies can cultivate a variety of animal proteins almost anywhere, Chin said.

  This appeals to companies looking for stable prices and predictable volume to help them overcome volatility in food supplies, as well as those wanting to source closer to consumers, said J.Y. Chow, who leads Mizuho Bank’s efforts to finance agriculture and food projects in the region.

  Governments can benefit, too, with the COVID-19 pandemic and trade conflicts showing the need to secure and localize food production.

  “Now we can shrink the footprint to a single point where the bioreactor is,” Chan said.

  Traceability and consistent quality are also big draws, said Markus Haefeli, the outgoing chairman of Regal Springs, one of the world’s largest responsible tilapia producers.

  The UNFood and Agriculture Organization said in a report last yearthat one-third of the world’s fish stocks are overfished.

  Other studies predict that the ocean is likely to have more plastics than fish by 2050, with levels of microplastics, heavy metals and contaminants increasingly tainting seafood.

  Concerns about animal rights can also help drive a switch to lab-grown meat.

  “The whole notion that you don’t need to kill animals to eat protein from animals is a huge argument,” said Haefeli, who has invested in Avant.

  FUNDAMENTAL SHIFT

  The idea of eating lab-grown meat has become more palatable to consumers, especially in Asia, in the past few years.

  A 2019 survey published in the academic journal Frontiers in Sustainable Food Systems showed that people in China and India are more open to consuming cultivated meat than consumers in the US.

  “The street food in Hong Kong is a bit scary. You don’t know what the source is,” said Minnie Cheung, a 30-year-old yoga teacher who tasted the lab-grown fish in Leung’s kitchen.

  “If I wasn’t told it was cultivated fish, I would think it was gourmet-quality fish made into a burger.”

  Still, many people are sceptically about eating lab-grown fish, both because it is not natural and because they believe it is genetically modified food.

  Yet cultured seafood is not genetically modified, Chow said — a point that highlights the importance of education and clear labeling in getting people to embrace cultivated meat.

  “The critical point is not only to educate the consumer on the how — meaning the process and how safe it is — but also the why,” he said.

  That includes explaining why alternative proteins are important and “what are the benefits for you, for animal welfare, for the planet,” Chow said.

  As well as getting the right information to consumers, the success of cultivated meat and seafood would depend on getting the price right, Chow said.

  Right now lab-grown fish — which is not yet available commercially — is set to supply a niche market, where consumers are willing to pay a premium, rather than the mass market, Chow said.

  However, cultured meats have the potential to disrupt the US$1 trillion conventional meat industry, according to a 2019 report from global consultancy A.T. Kearney.

  The report predicted that cultured meats would make up 35 percent of global meat consumption within the next 20 years.

  Industry insiders like Haefeli hope that changing what people put on their plates will be part of a fundamental shift in attitudes toward the health of the planet.

  “Will we look back and say: ‘Hey, people were still driving their own cars, they were still burning fuel for their cars and they were still killing animals to eat protein?’” he asked. “Can you imagine?”
