What You Need to Know
Controlled atmosphere packaging suppresses aerobic spoilage by limiting O₂, acidification drives lactic‑acid fermentation converting waste into vinegar, high‑pressure processing inactivates enzymes such as polyphenol oxidase, thermophilic composting kills pathogens while reducing odor, edible chitosan coatings reduce water loss, and lactic‑acid fermentation lowers pH to preserve nutrients. These processes target microbial growth, enzymatic browning, respiration, and pathogen proliferation through precise temperature, pH, and pressure controls.
