textured soy protein chunks or strips

Textured soy protein (TSP), also known as textured vegetable protein (TVP), is a dehydrated soy product derived from defatted soybean flour produced during oil extraction. Created through an extrusion process that forces soy flour under heat and pressure through dies, TSP is allowed to cool and dry, creating a porous, sponge-like structure. The resulting chunks or strips are tan to brown in color, with a firm, slightly chewy texture when rehydrated. TSP is flavorless and odorless in its dry form, absorbing the flavors of accompanying liquids and seasonings with notable efficiency.

TSP is available in various sizes and shapes—small crumbles, larger chunks, or elongated strips—designed to mimic the texture of ground, diced, or shredded meat. It contains minimal fat and no cholesterol, making it a shelf-stable meat alternative that has been a staple of plant-based and budget-conscious cooking since its development in the 1960s.

Textured soy protein serves as a versatile meat substitute in both Western and global cuisines. TSP chunks and strips are commonly rehydrated in hot broth or water and incorporated into dishes traditionally made with ground beef, such as tacos, Bolognese sauces, chili, and meat-based casseroles. The strips are particularly suited to stir-fries, stews, and curry preparations where they readily absorb the sauce's flavors and provide a satisfying textural contrast.

In vegetarian and vegan cooking, TSP is fundamental to creating the mouthfeel and bulk of meat-containing dishes without animal products. The ingredient benefits from pre-soaking in flavorful liquids (soy sauce, vegetable broth, or wine) before cooking. It pairs well with bold seasonings, umami-rich ingredients (mushrooms, soy sauce, miso), and tomato-based preparations. TSP's neutral flavor makes it adaptable across cuisines, from Mexican and Italian to Asian and Middle Eastern applications.
