Ferrous lactate formation of harmful substances such as

Minimize the acidity of fermented grains , reducing calcium lactate, ferrous lactate and other harmful substances formed to increase the pool of fermented grains into the water, so that yellow water Lactic acid lactate excluded fermented grains after the pit , pit wall must be attached Grains clean with a broom , and then use the yellow water , wine tail, curved pink , caproic acid solution poured scattered evenly, so that a long period of strong state mud pit , pit out really good wine. Raw protein species breeding on microbial metabolites have important implications for the different raw materials ratio, adjusted medium N ratio , buffered lactic acid impact on microbial taxa . Bacteria, yeasts need more nitrogen , the most suitable medium C / N at about 5:1 ; mold requires more carbon-based nutrients, suitable medium C / N at about 10:1 . Different ratio of raw materials for molds, yeasts , bacteria taxa have a moderating effect.
