For the first time, U.S. regulators on Wednesday approved the sale of chicken made from animal cells, allowing two California companies to offer 香蕉视频直播渓ab-grown香蕉视频直播� meat to the nation香蕉视频直播檚 restaurant tables and eventually, supermarket shelves.

The Agriculture Department gave the green light to Upside Foods and Good Meat, firms that had been racing to be the first in the U.S. to sell meat that doesn香蕉视频直播檛 come from slaughtered animals 香蕉视频直播� what香蕉视频直播檚 now being referred to as 香蕉视频直播渃ell-cultivated香蕉视频直播� or 香蕉视频直播渃ultured香蕉视频直播� meat as it emerges from the laboratory and arrives on dinner plates.

The move launches a new era of meat production aimed at eliminating harm to animals and drastically reducing the environmental impacts of grazing, growing feed for animals and animal waste.

香蕉视频直播淚nstead of all of that land and all of that water that香蕉视频直播檚 used to feed all of these animals that are slaughtered, we can do it in a different way,香蕉视频直播� said Josh Tetrick, co-founder and chief executive of Eat Just, which operates Good Meat.

The companies received approvals for federal inspections required to sell meat and poultry in the U.S. The action came months after the U.S. Food and Drug Administration deemed that products from both companies are safe to eat. A manufacturing company called Joinn Biologics, which works with Good Meat, was also cleared to make the products.

Cultivated meat is grown in steel tanks, using cells that come from a living animal, a fertilized egg or a special bank of stored cells. In Upside香蕉视频直播檚 case, it comes out in large sheets that are then formed into shapes like chicken cutlets and sausages. Good Meat, which already sells cultivated meat in Singapore, the first country to allow it, turns masses of chicken cells into cutlets, nuggets, shredded meat and satays.

But don香蕉视频直播檛 look for this novel meat in U.S. grocery stores anytime soon. Cultivated chicken is much more expensive than meat from whole, farmed birds and cannot yet be produced on the scale of traditional meat, said Ricardo San Martin, director of the Alt:Meat Lab at University of California Berkeley.

The companies plan to serve the new food first in exclusive restaurants: Upside has partnered with a San Francisco restaurant called Bar Crenn, while Good Meat dishes will be served at a Washington, D.C., restaurant run by chef and owner Jose Andr茅s.

Company officials are quick to note the products are meat, not substitutes like the Impossible Burger or offerings from Beyond Meat, which are made from plant proteins and other ingredients.

Globally, more than 150 companies are focusing on meat from cells, not only chicken but pork, lamb, fish and beef, which scientists say has the biggest impact on the environment.

Upside, based in Berkeley, operates a 70,000-square-foot building in nearby Emeryville. On a recent Tuesday, visitors entered a gleaming commercial kitchen where chef Jess Weaver was sauteeing a cultivated chicken filet in a white wine butter sauce with tomatoes, capers and green onions.

The finished chicken breast product was slightly paler than the grocery store version. Otherwise it looked, cooked, smelled and tasted like any other pan-fried poultry.

香蕉视频直播淭he most common response we get is, 香蕉视频直播極h, it tastes like chicken,香蕉视频直播櫹憬妒悠抵辈�� said Amy Chen, Upside香蕉视频直播檚 chief operating officer.

Good Meat, based in Alameda, operates a 100,000-square-foot plant, where chef Zach Tyndall dished up a smoked chicken salad on a sunny June afternoon. He followed it with a chicken 香蕉视频直播渢high香蕉视频直播� served on a bed of potato puree with a mushroom-vegetable demi-glace and tiny purple cauliflower florets. The Good Meat chicken product will come pre-cooked, requiring only heating to use in a range of dishes.

Chen acknowledged that many consumers are skeptical, even squeamish, about the thought of eating chicken grown from cells.

香蕉视频直播淲e call it the 香蕉视频直播榠ck factor,香蕉视频直播櫹憬妒悠抵辈�� she said.

The sentiment was echoed in a recent poll conducted by The Associated Press-NORC Center for Public Affairs Research. Half of U.S. adults said that they are unlikely to try meat grown using cells from animals. When asked to choose from a list of reasons for their reluctance, most who said they香蕉视频直播檇 be unlikely to try it said 香蕉视频直播渋t just sounds weird.香蕉视频直播� About half said they don香蕉视频直播檛 think it would be safe.

But once people understand how the meat is made, they香蕉视频直播檙e more accepting, Chen said. And once they taste it, they香蕉视频直播檙e usually sold.

香蕉视频直播淚t is the meat that you香蕉视频直播檝e always known and loved,香蕉视频直播� she said.

Cultivated meat begins with cells. Upside experts take cells from live animals, choosing those most likely to taste good and to reproduce quickly and consistently, forming high-quality meat, Chen said. Good Meat products are a master cell bank formed from a commercially available chicken cell line.

Once the cell lines are selected, they香蕉视频直播檙e combined with a broth-like mixture that includes the amino acids, fatty acids, sugars, salts, vitamins and other elements cells need to grow. Inside the tanks, called cultivators, the cells grow, proliferating quickly. At Upside, muscle and connective tissue cells grow together, forming large sheets. After about three weeks, the sheets of poultry cells are removed from the tanks and formed into cutlets, sausages or other foods. Good Meat cells grow into large masses, which are shaped into a range of meat products.

Both firms emphasized that initial production will be limited. The Emeryville facility can produce up to 50,000 pounds of cultivated meat products a year, though the goal is to expand to 400,000 pounds per year, Upside officials said. Good Meat officials wouldn香蕉视频直播檛 estimate a production goal.

By comparison, the U.S. produces about 50 billion pounds of chicken per year.

It could take a few years before consumers see the products in more restaurants and seven to 10 years before they hit the wider market, said Sebastian Bohn, who specializes in cell-based foods at CRB, a Missouri firm that designs and builds facilities for pharmaceutical, biotech and food companies.

Cost will be another sticking point. Neither Upside nor Good Meat officials would reveal the price of a single chicken cutlet, saying only that it香蕉视频直播檚 been reduced by orders of magnitude since the firms began offering demonstrations. Eventually, the price is expected to mirror high-end organic chicken, which sells for up to $20 per pound.

San Martin said he香蕉视频直播檚 concerned that cultivated meat may wind up being an alternative to traditional meat for rich people, but will do little for the environment if it remains a niche product.

香蕉视频直播淚f some high-end or affluent people want to eat this instead of a chicken, it香蕉视频直播檚 good,香蕉视频直播� he said. 香蕉视频直播淲ill that mean you will feed chicken to poor people? I honestly don香蕉视频直播檛 see it.香蕉视频直播�

Tetrick said he shares critics香蕉视频直播� concerns about the challenges of producing an affordable, novel meat product for the world. But he emphasized that traditional meat production is so damaging to the planet it requires an alternative 香蕉视频直播� preferably one that doesn香蕉视频直播檛 require giving up meat all together.

香蕉视频直播淚 miss meat,香蕉视频直播� said Tetrick, who grew up in Alabama eating chicken wings and barbecue. 香蕉视频直播淭here should be a different way that people can enjoy chicken and beef and pork with their families.香蕉视频直播�
