Textured Soy Protein is commonly referred to as TSP. A fine texture is added to the soy protein concentrate resulting in a fine and yet fibrous mouth feel. This product is used as a meat substitute since it not only has a texture which can be considered similar to ground beef but is also high in protein. It is used by the food processing industry as a substitute for meat, chicken and pork to simulate these products. It is available as chunks as well as flakes. When hydrated it maintains its structure. A small amount of vinegar or lime juice helps in rehydration.
Nutritionally TSP is a rich source of protein containing a minimum of 35 % protein (on a moisture free basis). The protein content can go up to 70%. It is fat free and low in sodium.
