What You Need to Know
Salt brining at 10–15 % and temperatures of 4–10 °C initiates lactic acid bacteria that convert sugars to lactic acid, lowering pH to 3.5–4.0. Vinegar pickles use 5–10 % acetic acid heated to 70–80 °C, ensuring a final pH that inhibits Clostridium botulinum. The process balances salt inhibition of spoilage microbes with fermentation kinetics.
