中文摘要:

      目的 通过模糊数学综合评价结合响应面法优化南疆骏枣太阳能熟化工艺。方法 以南疆骏枣为原料, 采用模糊数学法构建南疆骏枣太阳能熟化工艺综合评分体系, 在单因素试验的基础上进行Box-Behnken中心组合试验和响应面分析, 对南疆骏枣太阳能熟化工艺进行优化。结果 综合评分体系评价南疆骏枣太阳能熟化工艺的主要指标为滋味、质地、外观、能耗、香气, 相应权重分别为0.30、0.25、0.15、0.15、0.15; 响应面分析表明各因素对综合评分影响强弱的顺序为载重>温度>风速; 最佳工艺条件为: 温度49.4 ℃、风速 2 m/s、载重0.96 kg, 在此条件下, 南疆骏枣太阳能熟化工艺综合评分为88.56。结论 基于模糊数学综合评价结合响应面法建立的模型相对准确, 优选的南疆骏枣太阳能熟化工艺方法可行, 可为太阳能技术工业化熟化南疆骏枣提供技术依据。

英文摘要:

      Objective To optimize the solar cooking process of south Xinjiang Jun jujube by comprehensive evaluation of fuzzy mathematics combined with response surface method. Methods The south Xinjiang Jun jujube was used as raw material. The comprehensive evaluation system of solar cooking process of south Xinjiang Jun jujube was constructed based on fuzzy mathematics, and Box-Behnken central combination test and response surface analysis were carried out to optimize the solar cooking process of south Xinjiang Jun jujube. Results The main indexes of the comprehensive evaluation system for evaluating the solar cooking process of south Xinjiang Jun jujube were taste, texture, appearance, energy consumption and aroma, and the corresponding weights were 0.30, 0.25, 0.15, 0.15 and 0.15, respectively. The response surface analysis showed that the order of influence of each factor on the comprehensive score was load>temperature>wind speed. The optimum process conditions were: Temperature 49.4 ℃, wind speed 2 m/s, load 0.96 kg. Under these conditions, the comprehensive score of solar cooking process of south Xinjiang Jun jujube was 88.56. Conclusion The model based on fuzzy mathematics comprehensive evaluation combined with response surface method is relatively accurate, and the optimized solar cooking process of south Xinjiang Jun jujube is feasible, which can provide technical basis for industrialized cooking of south Xinjiang Jun jujube with solar technology.
