The US Department of Agriculture authorized two companies to sell artificial chicken meatthat is, from tissue grown in the laboratory, without animals to breed or slaughter.
In addition to meeting demands from animal groups, this new era in food production could reduce the impacts of grazing and forage cultivationas well as the great amounts of animal waste that contribute to the greenhouse effect.

Cultured meat is raised in six steps.
1. Biopsy. From a living animal, stem cells with the ability to differentiate and multiply are extracted.
2. Crop. The cells are placed in a medium with amino acids, carbohydrates, vitamins and minerals to encourage their growth.
3. Multiplication. They continue to grow in a bioreactor (a container with nutrients and controlled conditions of temperature and humidity) until they form a three-dimensional mass.
4. Differentiation. Through electrical stimulation and mechanical stretching techniques, the cells are converted into muscle fibers.

5. Structuring and maturation. The tissue is manipulated so that it grows with a texture similar to traditional meat. Nutrients are added to achieve ripening with pleasant flavors.
6. Prosecution. In general, in the form of hamburgers, nuggets or demenused meat.
Good Meat, one of the companies that received authorization from the White House, already sells meat grown in Singapore, the first country to allow it. The other, Upside Foods, said in a statement that it is “subject to rigorous inspections and food safety standards similar to those for conventionally produced poultry.”

Seven months ago, the Food and Drug Administration (FDA) had confirmed that these products are as safe as conventional ones.
In April of last year, following a placement that raised $400 million in capital, Upside Foods received a valuation of more than $1 billion. Although manufacturing meat is still much more expensive than producing it conventionally, the business is booming, and it is believed that will reach USD 25 billion in 2030.
