摘要:

采用响应面法对玉米须袋泡饮料的冲泡工艺进行优化。通过感官评定和测定多糖含量,对9 种玉米须袋泡饮 料配方进行筛选。在最佳配方基础上,通过单因素试验和响应面试验,对玉米须袋泡饮料的冲泡工艺进行优化。结果 表明,最佳冲泡工艺条件为:取1 g原料、目数40、加水量190 mL、冲泡时间17 min,在此条件下,冲泡液中多糖含量为 (75.87±1.60)mg/g,与理论值(76.04 mg/g)相近。利用响应曲面法优化玉米须袋泡饮料的冲泡工艺是可行的。

Abstract:

The brewing process for corn silk tea bags was optimized using response surface methodology. Nine formulations
of corn silk tea bags were analyzed by sensory evaluation and determined for polysaccharide content. The best formulation
was selected based on the analysis results and response surface methodology was used to optimize the brewing process. The
results showed that the experimental polysaccharide content in the brewing liquid was (75.87 ± 1.60) mg/g, which was
close to the predicted value of 76.04 mg/g, under the optimized conditions: brewing 1 g of raw materials (corn silk, Imperata
cylindrical rhizome and Stevia rebaudiana, 0.600 0:0.380 0:0.020 0, m/m) ground to 40 mesh with 190 mL of water for 17 min.
Therefore, it is feasible to optimize the brewing process of corn silk tea bags using response surface methodology.

Key words: corn silk, polysaccharides, sensory evaluation, Imperata cylindrical rhizome, Stevia rebaudiana
