一种提取桑椹果胶的新方法

A New Method of Extracting Mulberry Pectin

本文对桑椹果胶提取的常规方法进行了研究，提出了以高价铁盐作为沉淀剂的提取工艺，该工艺具有产率高，产品色泽好、成本低的优点，且将最终产品由常规方法的果胶酸盐改换成果胶酸，便于进一步应用。

The authors carry out the research in the conventional extraction of mulberry pectin,presenting a new process of pectin-extraction. Owning to the use of ferric (Ⅲ) as tLhe precipitant,this process results in higher yield, gooh quality with less cost in contrast with the conventional method. Furthermore, its final product is pectic acid, which is different form the conventional process.
