The biological mechanism of lactic

The biological mechanism of lactic acid bacteria plays an important role in the production of high-quality food foramen can ferment carbohydrate in food to secrete lactic acid bacteriocin, produce organic or alcohol and carbon dioxide, etc. , to inhibit the growth of some * Bacteria or pathogenic bacteria and improve the quality and flavor of food after fermentation, bacteria can increase the digestibility of food and produce some who vitamins, antioxidants. In recent years, lactic acid bacteria inhibit the role of some bacteria and pathogenic bacteria in food lactic acid bacteria inhibit the role of food microorganisms general bacteria growth of the optimal Ph value of 6-7 if below this position, the growth rate of bacteria will be greatly reduced or do not grow or even die, this is particularly visible in microorganisms. The inhibitory effect of acid produced by lactic acid bacteria on microorganisms in food has been proved in many experiments. The inhibitory effect depends on three factors: 1, mass value of medium, 2 degree of acid dissociation and 3 kinds of acid
