Description
Medieval pickling used salt brine and vinegar to create an acidic environment that inhibited spoilage organisms while promoting lactic acid fermentation.
Technical
Salt brine (8–10 % NaCl) creates an osmotic barrier that limits water activity, while lactic acid bacteria (e.g., Lactobacillus plantarum) ferment sugars to lactic acid, lowering pH to 3.5–4.0 over 3–7 days. Acetic acid from vinegar provides a rapid pH drop to 2.5–3.0, acting as an additional preservative.
Science
Primary Reaction
Fermentation of sugars by lactic acid bacteria producing lactic acid; acidification by vinegar (acetic acid).
