The company Shiok Meats in Singapore aims to bring laboratory-grownshrimpto the food industry.

Concerns about health,animals and the environment are leading more people to remove meat from their diet.Plant-based meat alternatives,popularized by Beyond Meat Incorporated and Impossible Foods, increasingly appear in supermarkets and restaurants.

But what some people call clean meat—meat grown from cells in a laboratory—is still an idea that is just beginning.

More than 24 companies are testing labgrown fish,beef and chicken.These businesses hope to enter the alternative meat market,which could be worth$140 billion by 2029.That estimate comes from Barclays,a financial services company.

Shiok Meats grows its product by taking shrimp cells and keeping them at a temperature of 28 degrees Celsius.They are then given nutrients in a solution.The cells become meat in four to six weeks.

This lab-grown meat's price is high.One kilogram of it now costs $5,000, said Shiok Meats'Chief Executive Sandhya Sriram.

At that cost, a single pork and shrimp dumpling could be as much as$300.

Sriram,a vegetarian,hopes to cut the cost to$50 for one kilogram by the end of this year.She also hopes to sign a new low-cost deal for nutrients that help grow the shrimp cells.

“We are looking at next year,so we might be the first ever company tolauncha cell-based meat product in the world,”Sriram said.Shiok Meats still needs approval from the city-state's foodregulator.

Although people increasingly demand meat alternatives,cell-based meat companies still faceresistanceto their products.

In Singapore,some people said they would try lab-grown meat.

“I am willing to try,”said 60-year-old Pet Loh,while she shopped for shrimp in a Singapore market. “I may not exactly dare to eat it frequently,but I don't mind buying and trying it because the animals in the oceans are declining.”

Any alternative ways of making animal protein without harming the environment are positive,said Paul Teng,a specialist in agritechnology at Nanyang Technological University. But,he added,more studies are needed to understand any negative results of makingcellularprotein.
