What You Need to Know
The process begins with thermal denaturation of soy or pea protein isolates at 70–80 °C, forming a continuous film. Transglutaminase (0.5–1 % w/w) cross‑links glutamine–lysine residues at 37 °C for 2 h, enhancing inter‑sheet adhesion. Adding 2 % NaCl during casting reduces solubility, increases tensile strength, and improves moisture retention.
