Study on the Properties and Extraction of Dietary Fiber from Guanximiyou Pomelo Peel
摘要
Abstract
The extraction of dietary fiber in pomelo peel from pinghe county, Fujian Province was studied. The orthogonal test, based on the extraction rate and the 3：1 ratio of IDF/SDF was designed to determine the best extrac- ting condition on NaOH concentration, extracting temperature and extracting time. The results indicated that, the best extracting conditions of total dietary fiber （DF） from pomelo peel were ： NaOH concentration was 8% , extracting temperature was 90℃ and extracting time was 90 rain. Under the above conditions, the extraction rate was 75.12% and the ratio of IDF/SDF was 2. 12. The size of TDF from 0-120 mesh was 30. 13% , followed by 120-140 mesh （21.84%）. Fine water holding capacity in IDF was 17. 642 0 g/g. However, the best expansibility was SDF （5. 711 5 g/g）. The data showed that significant absorbed capacity of DF on NO2- was under pH 2 and pH 7. The capacity that DF absorbed NO2- increased while the time increased, and pH 2 was better than pH 7. The capacity that DF absorbed unsaturated fatty acids was better than saturated fatty. This suggested the DF adsorption on animal lipid was superior.关键词
