What You Need to Know
Blanching in boiling water halts enzymatic oxidation, while rapid cooling preserves vitamin C. Controlled fermentation at 30 °C promotes lactic‑acid bacteria that lower pH and inhibit spoilage. Sous‑vide at 55 °C tenderizes collagen without overcooking, and low‑heat drying reduces moisture to <10 % to prevent microbial growth. Brining at 4 °C with 5 % salt preserves fish off‑cuts by creating an inhospitable environment for pathogens.
