摘要
探讨了以油莎豆为原料提取水溶性糖的最佳工艺条件。结果表明,各因素对油莎豆水溶性糖提取率的影响大小为浸提温度>浸提时间>料液比。本法油莎豆水溶性糖的提取最佳工艺条件为:浸提温度90℃、浸提时间40 min、料液比1∶12,在此条件下水溶性糖的提取率为81.4%。通过薄层层析鉴定,油莎豆水溶性糖的组成为蔗糖、棉子糖、葡萄糖、果糖。
This paper is designed to study the technical condition of water-soluble sugars extraction from Cyperus esculeutus.The experimental results showed,the influence of various factors on the water-soluble sugars extraction rate were extraction temperature extraction time solid-liquid ratio.The optimum technological condition is: extraction temperature 90 ℃,extraction time 40 min,solid-liquid ratio 1∶12,extraction rate is 81.4%.By thin-layer chromatography identification,the composition of Cyperus water-soluble sugars is sucrose,raffinose,glucose,fructose.
