Dietary fiber of Chinese white olives

The total dietary fiber(TDF),insoluble dietary fiber(IDF)and soluble dietary fiber(SDF)contents were determined for the fruits of Changying,Hui Yuan,Zilaiyuan,Tanxiang and Tantou olives.Changes in the contents of different dietary fiber(DF)in Changying,Huiyuan and Zilaiyuan olives at different development stages were studied.The results indicated that the Chinese white olives were rich in DF,especially the TDF in Changying and Zilaiyuan varieties,i.e.,37.40～50.36 g 100g-1 dry weight.Significant differences were found on TDF among the varieties.TDF consists of IDF and SDF.And,IDF and SDF in the fruits significantly correlated to the TDF contents.The changes in TDF,IDF and SDF in these Chinese white olives were similar.They increased gradually during the growth period.This paper discusses application of the different varieties for a source of DF.
