摘要
选取三门峡地区种植数量较多的红富士苹果作为原料,对其榨汁后残留果渣进行去除果胶酶等预处理制得干果渣粉末,筛选出最适萃取剂,采用超声波辅助酸解法进行苹果渣中果胶物质的提取,以果胶产率为评价指标分别设计单因素及正交试验,最终得出此方法的最佳工艺条件组合为A2B3C3D3,即超声波频率65 k Hz,提取温度80℃,提取p H值1.8,提取时间120min,此条件下果胶产率可达13.12%。
This research selected Red Fuji Apple planted in Sanmenxia area as material, filtered out most suitable extraction agent, used ultrasonic auxiliary and acid solution method for the extraction of pectin material, used evaluation indicators based on pectin produced rate for respectively design single factors and the orthogonal test, and eventually obtained that the best process conditions combination of this method was A2B3C3D3. the best ultrasonic frequency was 65 kHz, the best temperature was 80 ℃, the best pH was 1.8, the best time was 120 min. according these conditions pectin yields could reach to 13.12.
