| 摘 要： | 以杏皮渣为原料,研究杏皮渣白兰地生产中酒精发酵阶段的主要工艺条件。对杏皮渣浆液的制备方式、最佳酵母的筛选、接种量、初始含糖量、发酵温度、初始pH以及在发酵过程中酒精度和残糖的变化进行了研究。结果表明,杏皮渣浆的最佳制取方式采用高压蒸煮和酶解结合法:将杏皮渣和水按1∶6浸泡2 h后破碎打浆,121℃高压蒸煮10 min,冷却到室温后加入杏皮渣重量0.5%的果胶酶和1.5%的纤维素酶,在50℃下酶解4 h,得到的杏皮渣浆的还原糖含量为72.27 g/L。杏皮渣酒精发酵最佳工艺条件为:采用杏酒酵母No16,接种量为3%,初始含糖量为250 g/L,发酵温度为28℃,初始pH3.9,发酵时间为12 d,酒精度可以达到11.2%vol。
