摘要:

以薏米为原料,采用响应面法优化薏米酒的发酵工艺条件。在单因素试验的基础上,选取料水比、酵母接种量、发酵温度和发酵初始pH值为影响因素,以薏米酒的感官评分、总黄酮含量和酒精体积分数为响应值,应用Box-Behnken中心组合试验设计建立数学模型,进行响应面分析。结果表明:薏米酒最优的发酵工艺条件为:料水比1:4(m/V)、酵母菌接种量2.2%、发酵温度30℃、发酵初始pH 5.1。在此条件下薏米酒感官评分、总黄酮含量和酒精体积分数分别为88、138.97mg/L和9.24%。

Abstract:

The fermentation condition of CoixSeed wine was optimized by response surface methodology (RSM).
The impact of material/water ratio, yeast inoculums concentration, fermentation temperature and initial pH on
sensory score, anthoxanthin content and alcoholicity was investigated. The corresponding mathematical models
were established by Box-Behnken design. The optimal fermentation conditions were determined as follows: material/
water 1:4, inoculum amount 2.2%, fermentation temperature 30 ℃ and initial pH 5.1. Under the optimized
conditions, the sensory score, anthoxanthin content and alcoholicity were 88, 138.97 mg/L and 9.24% (V/V), respectively.
