LPT 321: Meat Science (1+1)

MEAT PROTEINS

• Meat is a concentrated source of proteins, which are far superior to the plant proteins due to very high biological value.
• Most lean meat cuts contain 16.5 to 20%  proteins.
• These proteins are rich in essential amino acids since there is no provision in the body for the synthesis of these amino acids and a deficient diet will lead to protein malnutrition.
• In fact, among meat proteins, myofibrillar and sarcoplasmic proteins are of very high quality because they contain enough of essential amino acids.
• Connective tissue proteins have lower levels of tryptophan and sulphur containing amino acids.
• Collagen is essentially poor in lysine content.
