What You Need to Know
Sous‑vide cooking at 60–65 °C denatures proteins (myosin, actin) without over‑cooking, while hydrocolloids such as xanthan gum or agar‑agar form stable gels or foams that stabilize emulsions. Rapid freezing at –80 °C or liquid nitrogen locks volatile aroma compounds and preserves crisp textures, and acidification to pH 4.0–4.5 inhibits Listeria monocytogenes and extends shelf life.
