摘要
目的 探讨黑豆皮色素的最佳提取条件和提取方法。方法 通过实验对黑豆的脱皮、提取溶剂的类型、浓度、料液比及浸提温度、时间、次数、pH值等进行了工艺参数比较及多因素条件下的正交实验,对影响提取率的因素进行了分析。结果 在确定的最佳条件下提取到两种黑豆色素成品,即色素浸膏和干燥的色素粉末。结论 检测数据可靠,提取方法简单合理。
AimThe optimum condition and method of extracting pigment from black soybean was discussed.MethodsThe technical parameters were compared by the multifactor hand over the experiments, such as peeling method of the black soybean, the impregnant′s type and concentration, the ratio of materiel and impregnant, the extraction temperature,time,and pH value etc,the factors which affect the pick-up rate were analyzed.ResultsIn the optimum condition,two kinds of finished products were extracted,which were the pigment ointment and the dry powdet.ConclusionThe technique of extracting was simple and logical, and the detected data was credible.
