摘要:

以含有一定酒精的桑椹汁为原料,采用一步发酵法即直接向原料中接种活化的醋酸菌液进行醋酸发酵酿造桑椹果醋,通过单因素试验和正交试验确定其最佳酿造工艺条件。结果表明,最佳酿造工艺条件为:酒精体积分数6%、搅拌转速130r/min、醋酸菌接种量15%(体积分数)。通过比较3 种单一澄清剂对桑椹果醋的澄清效果,结果表明:1% 壳聚糖溶液对桑椹果醋的澄清效果最佳,其最佳添加量为1.6mL/100mL。采用此工艺可以得到澄清透明、呈浅玫瑰红色、具有醋和桑椹复合风味的桑椹果醋。

Abstract:

Mulberry juice containing a certain amount of alcohol was directly inoculated with activated acetic acid bacterial culture for the production of mulberry vinegar by acetic acid fermentation. Based on a series of one-factor-at-a-time experiments, orthogonal array designs were applied to optimize some key technological conditions for the acetic acid fermentation of mulberry juice. Alcohol concentration of 6%, shake flask agitation speed of 130 r/min, innoculum size of 15% were found optimum. Chitosan solution of 1% was selected as an optimum clarifier out of 3 single ones and its optimum amount was 1.6 mL/100 mL. As a result, a clear, transparent, light rose colored and both vinegar-flavored and mulberry-flavored fruit vinegar product was obtained.

Key words: mulberry vinegar, one-step fermentation, technological conditions, clarifier
