Description
Citrus‑based pickling uses citric acid and salt to lower pH and create osmotic pressure, enabling lactic acid bacteria to ferment vegetables while inhibiting spoilage.
Technical
The addition of 1–2 % citric acid to a 5–10 % NaCl brine drops the pH to 3.5–4.0, creating an acidic, hypertonic environment that suppresses pathogens. Calcium ions in the vegetable matrix react with citric acid to form calcium citrate, reducing bitterness and improving texture. Lactic acid bacteria then ferment available sugars, producing lactic acid and volatile compounds that contribute to flavor and further lower pH.
