What You Need to Know
Thermal inhibition slows enzymatic activity and suppresses mesophilic bacteria, while osmotic pressure from salt brines and acidification from fermentation lower water activity and pH, creating hostile environments for spoilage organisms. High‑pressure processing and modified‑atmosphere packaging further disrupt microbial metabolism and oxidation, preserving texture and flavor without heat.
The Science
Primary Reaction
Thermal inhibition, osmotic pressure, acidification, pressure‑induced inactivation, and oxidation control collectively suppress microbial metabolism and enzymatic activity.
