人工窖泥的培养操作法

Culture Operation Methods of Manmade Pit Mud

采用二级液体种子10%,窖底泥5%,优质酒糟浸液60%,大曲粉5%,黄水20%,酵母膏0.05%,其他各类营养盐0.3%,酒头、酒尾5%,食用酒精1.5%为原料,在pH5～6,32～34℃,密封培养7～10d,制成己酸菌复合培养液,配以黄泥土、泥碳、窖皮泥、丢糟粉、大曲粉、生物酯化液、优级黄水、适量酒头、酒尾及N、P、K复合肥等制作“人工窖泥”。生产实践表明,效果很好,所产酒己酸乙酯和总酯较高,乳酸乙酯相对较低。(小雨)

secondary cultured liquid seeds, 5 % bottom pit mud, 60 % quality distiller′s grains steeping liquid, 5 % daqu powder, 20 % yellow water, 0.05 % yeast cream, 0.3 % other nutrient liquid, 5 % head liquor and ending liquor, and 1.5 % edible alcohol were used as materials, coupled with other conditions including pH 5～6, temperature 32～34 ℃, 7～10 d sealed culture, to produce caproate bacteria composite culture liquid. The culture liquid, with yellow clay, mud carbon, pit skin layer mud, distiller′s grains powder, daqu power, bio-esterified liquid, quality yellow water, adequate quantity of head liquor and ending liquor, and compound fertilizer N,P,K etc., was used to produce manmade pit mud. The production practice indicated that the manmade pit mud had satisfactory production effects, and liquor made by it had higher ethyl caproate content and total ester content and comparatively lower ethyl lactate content.(Tran. by YUE Yang)
