In a frozen meal, what is the purpose of TVP (textured vegetable protein)?

Textured vegetable protein (TVP) is primarily utilized in food products like frozen meals to retain water and add protein content. This alternative protein source is made from defatted soy flour, which contributes to the protein profile of the meal, making it more nutritionally balanced. Additionally, when TVP is rehydrated, it absorbs water, which helps maintain the moisture content of the meal during freezing and reheating processes. This results in a more palatable texture and enhances the overall eating experience.

While TVP may have some effects on taste and can contribute to visual appeal, its primary functions are focused on providing protein and moisture retention. It does not serve as an emulsifier; emulsifiers are agents that help combine two immiscible liquids, which is not a role that TVP fulfills in frozen meals. Thus, the key role of TVP in frozen meals is in enhancing both protein content and moisture retention.
