摘　　要：通过液体培养分别获得黑曲霉发酵液、己酸菌液等,再向液态体系中添加酯化混合物料,包括黄浆水、酒尾等,并调整pH、控制液态发酵物料比例、发酵温度、发酵时间等条件培养生物酯化液,将培养成熟的生物酯化液进行灌窖试验。结果表明,通过液态发酵制备的酯化液,可以充分利用黑曲霉产生的复合酶类并有效促进酯化作用,提高了液态发酵体系的酯化效率,在提高酿酒副产物资源综合利用率等方面起到的积极作用,酯化液的灌窖操作有利于提高浓香型白酒的产酒质量。Aspergillus Niger fermentation liquid, hexanoic acid liquid, etc. are obtained by liquid culture, and esterification mixed materials,including Huangjiangshui, wine tail, etc., are added to the liquid system, and the pH is adjusted, the proportion of liquid fermentation materials is controlled, the fermentation temperature, and the fermentation time. Conditions such as culture of bioesterification liquid, The mature biological esterification solution was prepared for the cellar test. The results show that the esterification liquid prepared by liquid fermentation can make full use of the compound enzymes produced by Aspergillus Niger and effectively promote esterification, improve the esterification efficiency of the liquid fermentation system, and improve the comprehensive utilization rate of wine byproduct resources. The positive role, The pit operation of esterification liquid is helpful to improve the quality of liquor production of Luzhou-flavor liquor.
