The Study And Usage Of Dietary Fiber And Other Functional Components In Chinese White Olive

TDF IDF and SDF contents were determined in the pulp of five varieties of Chinese white olive .The contents of some different kinds of dietary fiber, total soluble sugar, tannin and flavone in Changying,Huiyuan and Zilaiyuan were also determined during different developmental stages , and the dynamic changes of those functional components were analysed. The functional components of Chinese white olive pomace were determined and researched on its general utilization .The results were as follows:1 .Chinese white olive fruits were rich in dietary fiber . The contents of TDF in it were 37.40~50.36 g/100g DW .As far as edible part was concerned ,its DF contents were obviously more than that of other species of fruits. There were statistical differences boservably on the contents of TDF and IDF during the variation except SDF. Changying possessed the highest TDF and IDF ,and SDF contents in the pulp of Tanxiang was obviously higher than that of other varieties .Furthermore , in the pulp of Chinese white fruit ,the result indicated that IDF contents were significantly correlated with TDF contents.2. Dynamic changes of the contents of TDF IDF and SDF in three varieties of Chinese white olive were similarly during the whole developmental period. TDF contents increased with the later stage ,and its content increased quickly during the earlier developmental stage while increased slowly later. IDF contents also like that ,but from 4th September to ripe its content decreased slightly .Contents of SDF increased gradually before the fruits rotted.3. Total soluble sugars in the pulp increased gradually during the whole stages. In three varieties of Chinese white olive ,which were determined ,the contents of in changying were the highest as same as its growth increment. In contrast, with the Chinese white olive growing ,the contents of tannin decreased and decreased rapidly during the later developmental stage. The flavone contents increased quickly during the earlier developmental stage while decreased later. For all that ,the contents of flavone in the pulp of Chinese white olive were still obviously higher than that of other species of...
