What You Need to Know
By controlling temperature (15–30 °C) and salt concentration (10–15 % NaCl), these microbes produce acids that lower pH, inhibit spoilage organisms, and impart characteristic tangy flavors. The technique, recorded since the Tang dynasty, remains a cornerstone of Chinese culinary heritage. Modern studies confirm the role of Lactobacillus plantarum and acetic acid bacteria in flavor development and safety.
The Science
