Description
Zero‑waste cooking uses chemical and biological preservation to extend the life of food scraps while maintaining safety.
Technical
Acidification lowers pH to inhibit Clostridium botulinum, while lactic‑acid fermentation produces lactic acid that further suppresses spoilage microbes. Dehydration reduces water activity below critical thresholds, and pressure canning destroys spores by combining heat and pressure. These processes preserve nutrients and create new flavors through controlled chemistry.
Science
Primary Reaction
Acidification and lactic‑acid fermentation inhibit microbial growth; dehydration reduces water activity; pressure canning destroys spores.
