Description
A set of scientifically validated techniques that extend shelf life and reduce food waste.
Technical
These methods rely on controlling temperature, pH, water activity, and oxygen exposure to inactivate or inhibit spoilage microorganisms and enzymatic reactions. Heat processing (121 °C for 15–20 min) destroys Clostridium botulinum spores, while acidification (pH ≤ 4.0) and salt (2–5 %) create hostile environments for bacteria and yeasts. Vacuum sealing, MAP, and freezing immobilize microbes and enzymes, and dehydration removes water to a_w < 0.6, preventing growth.
