주로 약용이나 차용으로 종래 이용되고 있는 유자와 대추, 당과 Vitamin C등이 풍부하여 생식 뿐 아니라 가공품등으로 널리 이용되고 있는 감등의 국내 고유 과실중 근래기능성 식품소재로 활용되고 있는 식이섬유를 종류별로 과육과 과피로 분리하여 분석하였다. 유자과육과 과피의 식이섬유 함량은 과육부에서 불용성 식이섬유, 가용성 식이섬유, 총 식이섬유량이 신선물 기준으로 각각 2.61%, 1.25%, 3.47%이었으며, 과피부분에서는 각각 7.32%

This paper was performed to identify and determine dietary fibers considered as nutracerticals and for pharmaceuticals in Korean fruits, citron, jujube and persimmon. In the pulp and peel of citron, jujube and persimmon, the contents of dietary fiber were determined by the method of AOAC and Van Soest et al. The contents of dietary fiber(DF) in the pulp of citron were 2.61％ of insoluble dietary fiber (IDF) and 1.25% of soluble dietary fiber(SDF) based on wet weight. The contents of DF in the peel of citron were 7.32% of IDF and 0.71％ of SDF. The total pectin contents in the pulp and in the peel of citron were 1.77% and 3.19% respectively. The contents of IDF in the pulp of jujube were 2.98%, SDF 0.91 ％ calculated on wet weight basis. The contents of IDF were 16.88%, SDF 1.53% in the peel of jujube. The contents of DF in the pulp of persimmon were 1.95% of IDF and 0.31 ％ of SDF based on wet weight. The contents of IDF were 15.71 ％, SDF 2.46% in the peel of persimmon. In dietary fibers of Korean fruits, citron, jujube and persimmon, IDE were much higher than SDF and mainly in the pulp. Therefore, they would be good source of dietary fibers.
