| Abstract: | 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. |
