摘要
对水果醋液态发酵工艺进行优化。研究了扩培式、直投式发酵对醋酸发酵的影响;不同碳源氮源对醋酸发酵的影响,以及碳氮比的关系;对温度、接种量、通气量、酒精度等因素进行了正交试验,分析了各因素对醋酸发酵的影响效果,确定了最佳组合;最后通过果醋发酵试验,验证了醋酸发酵优化工艺能够提升产品品质,降低生产成本,并可以成功的用于实际生产。
The process of the fruit vinegar fermentation was opimized. The influences of directed vat set starter and test tube strain on acetic acid fermentation, and the influences of different carbon sources and nitrogen sources on acetic acid fermentation were studied. The best carbon-nitrogen ratio, th temperature, alcohol degree, inoculums size and volume of aeration were determined by using orthogonal test. It was proved that the optimization process can improve product quality and reduce the costs.
