Lactic fermentation is a biological process in which glucose or other sugars are converted into lactic acid by lactic acid bacteria. This process occurs in the absence of oxygen and is commonly used in food preservation and production. Lactic acid bacteria, such as Lactobacillus and Leuconostoc, are responsible for this fermentation. The resulting lactic acid lowers the pH of the food, creating an environment that inhibits the growth of harmful bacteria and spoilage organisms. This makes lactic fermentation a valuable method for preserving food, particularly in the production of dairy products like yogurt, kefir, and cheese, as well as in the fermentation of vegetables like sauerkraut and kimchi.

The process of lactic fermentation involves several steps. Initially, lactic acid bacteria consume glucose, producing lactic acid and carbon dioxide as byproducts. The lactic acid then lowers the pH of the food, which further inhibits the growth of other microorganisms. Additionally, the carbon dioxide produced can contribute to the texture and flavor of the fermented product. The fermentation process can be controlled by adjusting factors such as temperature, pH, and the presence of other microorganisms.

Lactic fermentation has been practiced for thousands of years and is an essential part of many traditional food cultures around the world. It is a sustainable and natural method of food preservation that does not require the use of heat or chemicals. The resulting fermented foods are often rich in nutrients and have unique flavors and textures that are highly valued by consumers. Lactic fermentation is also gaining popularity in the modern food industry as a method for producing functional foods with health benefits, such as probiotics and antioxidants.
