Description
Ancient Chinese pickling uses controlled salt and acid environments to promote lactic acid fermentation while suppressing spoilage organisms.
Technical
The process relies on precise salt concentrations (10–15 % w/w) to create osmotic pressure that inhibits spoilage microbes yet allows lactic acid bacteria to thrive. Brine temperatures of 20–25 °C and fermentation times of 3–7 days enable the conversion of sugars to lactic acid, lowering pH to 3.5–4.5. Vinegar or rice wine additions introduce acetic acid and ethanol, further suppressing pathogens and adding flavor.
