摘要: 以0.2mol/L的盐酸溶液萃取香蕉皮中的果胶,以正交试验法观察萃取液用量、萃取温度和萃取时间对果胶提取率的影响。结果表明:萃取液用量是原料的2倍、萃取时间为1.5h、萃取温度为85℃时,果胶的提取率相对较高。这与果胶物质的水解变化直接相关。

Abstract: Extraction of pectin in banana peel was studied using 0.2mol/L hydrochloric acid solution as an extractant. The operating conditions, including amount of the extractant, extraction temperature and time were optimized by orthogonal experimental investigation. It was found that the optimal concentration of extractant was twice as that of the raw material, and the time and the temperature were 1.5h and 85℃, respectively, which was correlated with hydrolysis of pectin substances.

Key words: banana peel, pectin, acid hydrolysis, extraction
