碱法一步提取鲜山药中多种水溶性威分的工艺研究
Optimization of technology for simultaneous extration of water-soluble components from fresh yam with alkaline medium
摘要
Abstract
Aiming to discuss the technology of simultaneous extracting multi-chemical components from yam under mild alkaline condition, the technological condition was confirmed by observing the index of the extraction rate of yam protein.The optimal condition was achieved as follow: the ratio of material to solvents was 1∶10 (g/mL),extracting 150min at pH9.0 under 45℃.Under the above conditions, the yield of the extract obtained was 6.90%,and the extraction rate of yam protein was 69.01%.The quantitative analysis showed that many chemical components could be extracted simultaneously using alkali method, the extraction rate of glycoprotein,polysaccharide, saponin and fatty acid reached 59.43 %, 71.85 %, 54.55 % and 16.70%, respectively.Therefore, the above extraction technology could enrich varied water-soluble components of fresh-yam.关键词
