Lactic acid is used as a food preservative, curing agent, and flavoring agent. [51] It is an ingredient in processed foods and is used as a decontaminant during meat processing. [52] Lactic acid is produced commercially by fermentation of carbohydrates such as glucose, sucrose, or lactose, or by chemical synthesis. [51]
Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells ...
Lactic acid bacteria are used in the food industry for a variety of reasons such as the production of cheese and yogurt products. Popular drinks such as kombucha are made using lactic acid bacteria, with kombucha having been known to have traces of Lactobacillus and Pediococcus once the drink is made. [23]
“This [lactic acid] is what gives buttermilk its tangy flavor and thicker consistency,” says Sam Barton, Senior Food Technologist at Organic Valley. Then, the buttermilk is heated.
Food acids are added to make flavors "sharper", and also act as preservatives and antioxidants. Common food acids include vinegar, citric acid, tartaric acid, malic acid, folic acid, fumaric acid, and lactic acid. Acidity regulators. Acidity regulators are used to change or otherwise control the acidity and alkalinity of foods. Anticaking agents.
Preservative. A preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes. In general, preservation is implemented in two modes ...
Biopreservation is the use of natural or controlled microbiota or antimicrobials as a way of preserving food and extending its shelf life. [1] The biopreservation of food, especially utilizing lactic acid bacteria (LAB) that are inhibitory to food spoilage microbes, has been practiced since early ages, at first unconsciously but eventually with ...
Species of Lactobacillus (and related genera) comprise many food fermenting lactic acid bacteria [39] [40] and are used as starter cultures in industry for controlled fermentation in the production of wine, yogurt, cheese, sauerkraut, pickles, beer, cider, kimchi, cocoa, kefir, and other fermented foods, as well as animal feeds and the bokashi ...
