【摘要】 为提高花色苷提取率,利用生物酶和超声波萃取技术提取蓝靛果果渣中花色苷,对提取效果进行比较。通过单因素和正交实验,确定了提取蓝靛果果渣花色苷超声波法的最佳工艺条件为:温度为35℃,时间为30min,固液比为1∶30,功率为400W。比较了酶和超声波萃取技术对蓝靛果果渣中花色苷提取效果的影响,得出酶-超声波法联用时蓝靛果花色苷的得率为43.04%,比酶解法提取花色苷提高5.12%,比超声波萃取法提取花色苷提高17.44%。更多还原

【Abstract】 In order to increase the yield of anthocyanins, the technology of biologic enzyme and supersonic extracting were used to compare the effect of anthocyanins from Lonicera caerulea L.fruit residue. The single factors and orthogonal design were done to study the best range of extracting anthocyanins with supersonic technology. The effects of extracting anthocyanins with enzyme and supersonic extracting were compared. The results showed that the optimum conditions were: temperature 35℃, time 30min, rate of solid and liquid 1∶30, power 400W. At last, the results were: the yield of anthocyanins with enzyme-supersonic technology was 43.04%. The yield of anthocyanins was 5.12% higher than that of enzyme method and 17.44% higher than that of supersonic extracting.更多还原
