中文摘要: 雪莲果作为试验材料,利用微波辅助提取法对雪莲果中的低聚果糖进行提取。在单因素试验结果的基础上,采 用正交试验设计,对雪莲果中低聚果糖的提取工艺进行优化,获得其最佳的提取工艺参数为微波时间 180 s,微波功率 700 W,提取温度 90 ℃,提取时间 80 min,液料比 40 ∶ 1(mL/g)。在此条件下,微波辅助提取低聚果糖的提取率为 51.33 %, 比未优化前 38.56 %的提取率提高了 0.33 倍。

Abstract:The process on the extraction of fructo-oligosaccharides from yacon was studied using microwave assisted extraction method. On the basis of single factor experiment, the extraction of fructo-oligosaccharides from yacon were optimized by the orthogonal experimental design .The results showed that the optimal conditions were microwave time 180 s, microwave power 700 W, extraction temperature 90 ℃, extraction time 80 min, liquid material ratio 40 ∶ 1 mL/g. Under optimization conditions, the extraction rate of microwave assisted extraction of oligosaccharide fructose was 51.33 %,and the extraction rate was 0.33 times more than 38.56 % of before optimization.
