摘要
以可可果皮为原料,采用酸水解法提取水溶性膳食纤维和水不溶性膳食纤维。结果表明,可可水溶性膳食纤维的最佳提取工艺为:料液比为1∶30,水浴温度90℃,pH 2.0,提取时间30 min,得率为25.19%。可可膳食纤维总得率达57.99%,不溶性膳食纤维的持水力为5.23g/g,溶胀性为11.42mL/g。
The water-soluble and non-water-soluble food fibers were extracted from cocoa husks using the acid-hydrolysis method. The optimal conditions to extract water-soluble dietary fiber were studied in orthogonal test. The results showed that the optimal parameters were stuff-to-water ratio 1 ：30, temperature 90℃, pH 2.0, extracting time 30 min, with the extraction rate of 25.19%. The cocoa husks dietary fiber content was 57.99%. The water holding capacity and expansion capacity were 5.23 g/g, 11.42 mL/g, respectively.
