In-vitro meat is the concept of growing meat in a laboratory environment. Growing meat in this way eliminates the need for farming in greenhouses and producing food for the animals. Nutrient solution for growing the meat can be isolated from plants grown in the greenhouse. In-vitro meat also eliminates the problem of what to do with the unwanted parts of the animal, such as bones, skin and offal. Although In-vitro meat is High-tech, it may use less space and energy and time to produce meat than raising animals would.
Muscle tone will need to be developed to produce a laboratory culture that suitably mimics common animal meat products, and atrophy must be addressed by stimulating the cultured tissues to contract against a resistant force on a regularly scheduled basis. Providing suitable resistant forces will necessitate the development of a frame or scaffolding (read skeleton) to which muscles may be bound and forced to exercise. An alternative may be the use of tissues to pump fluids in the same way as a human heart.
A more easily developed method may be to produce meat similar to that which comes from invertebrate animals having no significant skeletal structure. Examples include squid, octopus, snail, clam, and oyster. Meats of this form have textures which differ from other animal products. While resistant forces will be less necessary, these tissues will still require regular contraction to maintain mass and prevent muscle deterioration.
However, mimicking the texture of meat may not be needed. Sausages, hamburger patties and several other meat products are made of ground up meat, and have a different texture to normal meat. Gelatinous un-excersised meat may become a delicacy on Mars.
- In 2008 PETA offered 1 million USD prize to anyone who brought into market in-vitro chicken meat. This was abandoned in 2014.
State of the art
- GOOD Meat started marketing artificial chicken meat in 2020 in Singapore, where it got regulatory approval. The company started building a 15 million kg per year facility in 2022. The process is chicken cells from live chicken grown in biological reactor. The energy source and the 'food' for the chicken meat are: (need more data here).
- Other new advancements include the discovery that tobacco plants can be harnessed as a cost-effective source of growth factors for protein cultivation. This may potentially switch out fetal bovine serum used in cell-based production, which large industry stakeholders such as Aleph Farms and Wacker have made moves to eliminate. https://www.foodingredientsfirst.com/news/good-meat-builds-worlds-largest-bioreactors-to-produce-cultivated-meat.html https://www.foodingredientsfirst.com/news/biobetter-puts-tobacco-plants-to-positive-use-in-cell-based-meat-production.html
