中文摘要: 正交试验与 BP 人工神经网络模型优选菠萝蜜最少加工保鲜的工艺条件。以贮藏时间及感官评分为指标,结合 正交试验与人工神经网络方法,考察 CaCl2 浓度、壳聚糖浓度、气调包装成分及比例对贮藏保鲜工艺的影响。BP 神经网 络模型优化工艺为 CaCl2 浓度 0.30 %,壳聚糖浓度 0.75 %、气调包装成分及比例 5 %CO2+15 %O2+80 %N2;正交试验优选 的工艺条件为 CaCl2 浓度 0.30 %,壳聚糖浓度 0.50 %、气调包装成分及比例 5 %CO2+15 %O2+80 %N2;前者的感官评分高 于后者。
Abstract:Orthogonal experiment with BP artificial neural network model is preferably minimally processed jackfruit preservation process conditions.In storage days and sensory score for the index, and orthogonal experi- ment with artificial neural network to study CaCl2 concentration, concentration of chitosan, modified atmo- sphere packaging components and affect the ratio of Storage Technology.BP neural network model to optimize the process of CaCl2 concentration of 0.3 % chitosan concentration of 0.75 %,the proportion of modified atmo- sphere packaging components and 5 %CO2+15 %O2+80 %N2;orthogonal test process conditions for the CaCl2 concentration of 0.4 % chitosan concentration of 0.65 %,the proportion of modified atmosphere packaging com- ponents and 5 %CO2+15 %O2+80 %N2;former sensory score than the latter.
