Description
Water bath canning preserves high‑acid foods by submerging sealed jars in boiling water for a time calibrated to pH, jar size, altitude, and water level.
Technical
The process relies on heat to denature proteins and inactivate enzymes, thereby killing vegetative microbes. The low final pH (≤4.6) prevents germination of Clostridium botulinum spores, ensuring safety while maintaining texture and flavor when properly processed.
Science
Primary Reaction
Heat-induced protein denaturation and enzyme inactivation leading to microbial death, combined with low pH to inhibit spore germination.
