摘要: 利用盐渍藠头提取其风味物质,考查了pH值、温度、加热时间、商品果胶酶添加量对盐渍藠头中蒜素提取效果的影响。结果表明,果胶酶提取较为合适的工艺条件为:按原料比添加0.6%~1.2%的果胶酶,pH3.4、温度50℃左右下提取2~4h,此时蒜素的提取率可达到较高水平(0.21~0.27g/100ml),且出汁率效果也较好(90%~92%),固形物含量较高(19.2~19.8Brix),能较好的保持藠头特有的香气。

Abstract: The preliminary study results showed that taking 0.6% to 1.2% pectinase to extract flavor compounds from pickled Alliium chinense at pH 3.4 and 50 ℃for 2 h to 4 h, the higher allicin yield, juice yield and content of soluble solid are attained, which are from 0.21g/100 ml to 0.27 g/100 ml, from 90% to 92% and from 19.2 Brix to 19.8 Brix, respectively. Meanwhile, the specific aroma of Alliium chinense is kept well.
