What You Need to Know
High‑temperature extrusion denatures proteins, forming fibrous structures that mimic muscle tissue, while fermentation of pea protein generates glutamate‑rich flavor compounds such as 5′‑methyl‑2‑isoxazole‑3‑yl‑amine, enhancing umami perception. Precise control of temperature, time, moisture, and salt is essential to avoid rubbery or soggy outcomes, and microbial stability is maintained through dehydration or preservatives.
The Science
Primary Reaction
High‑temperature extrusion denatures plant proteins and aligns them into fibrous structures; fermentation of pea protein produces glutamate‑rich flavor compounds.
