摘要:以枸杞为原料,通过单因素实验和正交试验对发酵枸杞汁的发酵温度、发酵时间、接种量、蔗糖添加量4 个因素进行研究,旨在得到一款酸甜可口、状态均一稳定的发酵枸杞汁。以发酵终点的pH值和产品的感官评分为评价指标,对最优发酵工艺进行研究。结果表明,品质最佳的发酵枸杞汁的发酵工艺条件为:发酵温度37℃,发酵时间5 h,接种量5%,蔗糖添加量6%。

Abstract: Using lycium barbarum as raw material,the fermentation temperature,fermentation time,inoculumamount and sucrose addition amount of fermented lycium barbarum juice were studied by single factor test andorthogonal test,in order to obtain a sweet and sour taste, uniform and stable fermented Chinese wolfberry juice. Theoptimal fermentation process was studied by using the end-point pH and sensory score of the product as evaluationindexes. The results showed that the optimal fermentation conditions were as follows:fermentation temperature 37℃,fermentation time 5h,inoculum amount 5% ,sucrose addition amount 6% .
