What You Need to Know
Sous‑vide cooking preserves protein tertiary structure by maintaining temperatures below irreversible denaturation thresholds, while spherification relies on ionic crosslinking of alginate with calcium ions to form gelled spheres. Agar‑agar gelation and flash‑freezing exploit phase‑change dynamics to create novel textures, and water activity manipulation controls microbial stability.
