摘要
干香蕉根含果胶物质21.13％。用硫酸萃取乙醇沉淀法提取香蕉根果胶,最佳条件是煮沸10分钟,每克干原料(含水量12.29％)加0.1N硫酸50毫升,底物乙醇浓度为60％,煮沸操作进行两次。提取率为94.32％。
Dried banana root contains 21.13% pectin. Applying the method of extractionresidum with sulphuric acid, the extraction percentage of pectin from dried banana root with 12.29% moisture was 94.32% after boiling two times each for 10 min., and in 50 ml 0.1N H_2SO_4 per gram of dried root and 60% ethanol as substrate.
