摘要
对提取叶绿素铜钠盐和叶酸的蚕沙废液进行了提取果胶的生产工艺研究。结果表明,提取了叶绿素铜钠盐和叶酸的蚕沙废液可用来进一步提取果胶,提取的低甲氧基果胶颜色较好,性质稳定,质量达到国家标准。提取果胶的最佳条件为:采用活性炭脱色,沉析时的pH值控制在3.5,沉析温度为50℃,浓缩液与沉淀剂95%的乙醇用量以1∶1.1为宜。
The results from studying the extraction technology of pectin from silkworm excrement waste solution showed that the color and property of methoxyl pectin extracted from silkworm excrements waste solution are good and stable, and its quality meets the national standard. The optimum extraction condition includes active carbon for decolorization, pH 3.5 and 50℃ for sedimentation, and concentrated solution to 95% alcohol should be 1 ： 1.1.
