What You Need to Know
The process relies on lactic acid bacteria, primarily Lactobacillus spp., converting sugars into lactic acid, which lowers the pH to 3.5–4.0. The concurrent presence of acetic acid (vinegar) and a 5–10 % salt concentration creates a synergistic preservation effect that inhibits spoilage organisms while maintaining vegetable crispness and nutritional quality.
The Science
Primary Reaction
