What it is

Texturized soy protein (TSP), also known as soy protein isolate or textured vegetable protein, is a meat substitute made from defatted soy flour. The flour is processed with heat and pressure to create a fibrous, chewy texture that mimics meat.

Why it's used

Manufacturers use TSP as a protein source and meat extender in products like vegetarian burgers, sausages, and chili. Its meat-like texture makes it a popular ingredient in plant-based meat alternatives and can also be found in some processed meat products to improve texture and reduce cost.

Health notes

Texturized soy protein is generally recognized as safe (GRAS) by the FDA. It is a good source of protein and isoflavones, which have been studied for potential health benefits. International bodies like JECFA have evaluated soy proteins. Evidence on the health effects of soy consumption is mixed, with some studies suggesting benefits and others raising concerns, particularly regarding hormonal effects.

Allergen info

Soy is one of the 9 FDA major allergens. Texturized soy protein is derived from soy.
