摘要:采用超声提取工艺提取灰枣低聚糖,以低聚糖得率为指标,在单因素试验的基础上,采用正交试验优化提取工艺,得到灰枣低聚糖超声提取最优工艺条件为超声功率200 W、提取温度60 ℃、提取时间40 min、料液比1∶10g/mL,在此条件下进行3次重复试验,得率达到1.38%,且灰枣低聚糖具有促进两歧双歧杆菌生长的功能。

Abstract: Ultrasonic extraction process was used to extract grey jujube oligosaccharides. Taking yield of oligosaccharides as an index,based on a single factor experiment,orthogonal experiments were used to optimize extraction process. The obtained optimal ultrasonic extraction process conditions for grey jujube oligosaccharides were ultrasonic power 200 W, temperature 60 ℃, extraction time 40 min, and solid-liquid ratio 1∶10 g/mL. Under these conditions,three repeated experiments were conducted with a yield of 1.38%,and the grey jujube oligosaccharides had the functions of promoting the growth of Bifidobacterium.
