  • Retarding effects of the dietary fibers from tangerine peels on glucose, bile acid and cadmium transport were evaluated by dialysis method, and were compared with those of commercial dietary fibers(citrus pection, CM-cellulose, guar gum, $\alpha$-cellulose). Yields of total (TDF), insoluble(IDF) and soluble dietary fibers(SDF) from tangerine peels on the fresh matter basis were 2.84%, 1.95% and 0.39% respectively. The amount of insoluble fibers was 5.2 times higher than that of soluble fibers. Soluble fibers(guar gum, CM-cellulose, SDF, pectin) had the retarding effect on glucose transport, while IDF, TDF and $\alpha$-cellulose did not have. Guar gum showed the greatest effect, followed by CM-cellulose, SDF and pectin. Among the extracted fibers, only SDF had the effect on glucose transport retardation. Regarding bile acid dialysis, guar gum had the greatest retarding effect, and all dietary fibers from tangerine peels, especially SDF, showed the effect of bile acid retardation. On cadmium transport retardation, CM-cellulose had the greatest effect, followed by SDF, TDF, IDF, guar gum and pectin. Among the extracted fibers, SDF had the greatest effect on Cd trasport transport retardation. The extracted dietary fibers showed higher retarding effect on Cd transport than glucose and bile acid transport, and the effect of SDF was higher than IDF.

  • 동아를 autoclaving, boiling, microwaving 처리하고 그에 따른 물리적 특성과 in vitro 생리적 특성의 변화를 조사하였다. 열처리 방법에 따른 보수력은 microwaving이 9.43 g/g으로 가장 높았으며 boiling(5.12 g/g), 무처리(4.63 g/g), autoclaving(2.61 g/g) 순으로 낮아졌다. 팽윤력은 열처리 동아의 경우 $22.4{\sim}25.8\;mL/g$으로 무처리(18.0m L/g)보다 높은 것으로 나타났다. 동아의 calcium 흡착력은 microwaving, boiling, 무처리, autoclaving 순으로 나타났으며 autoclaving의 경우 나머지 처리의 30% 정도의 낮은 흡착력을 나타내었다. 열처리동아의 세포조직은 autoclaving 처리에 의하여 가장 심한 구조적 변형을 보였다. 반투막을 이용하여 in vitro법으로 확인한 glucose 투과 억제효과는 boiling 처리에 한해서 20.6%(투석 1시간)로 나타났다. Bile acid 투과 억제효과는 boiling, autoclaving, microwaving, 무처리 순으로 각각 22.9, 17.1, 14.3, 8.6%(투석 1시간)의 투과 억제효과를 보였다. Cadmium투과 억제효과는 열처리 방법에 관계없이 65% 이상으로 높게 나타났다.

  • Retarding effects of the dietary fibers from persimmon peels (PTDF ; total dietary fibers, PIDF ; insoluble dietary fibers, PSDF ; soluble dietary fibers) and dried jujubes (JTDF ; total dietary fibers, JIDF ; insoluble dietary fibers, JSDF ; soluble dietary fibers) on glucose, bile acid and cadmium transport were evaluated by in vitro dialysis sack method. These effects were compared with those of commerical citrus pectin, CM-cellulose (CMC) and $\alpha$-cellulose. Yields of PTDF, PIDF and PSDF on wet weight basis were 14.04% , 11.61%, 1.76%, respectively, and those from dried jujubes were 14.80%, 9.98% and 2.80%, respectively. The amount of soluble fibers in JTDF was higher than PTDF. Soluble fibers had the retarding effects on glucose transport but insoluble fibers did not have. CM-cellulose showed the greatest retarding effect, which was followed by citrus pectin and JSDF. Among the soluble fibers, PSDF had the lowest retardig effect. Retarding effect of TDF was dependent upon the amount of SDF in TDF. Regarding bile acid dialysis , insoluble dietary fibers as well as soluble dietary fibers showed the retarding effects, among which JSDF had the greatest retarding effects, among which JSDF had the greatest retarding effect, followed by citrus pectin. Among the extracted fibers, dietary fibers from dried jujubes were more effective than these from persimmon peels, and SDF seemed to show higher retarding effects than IDF and TDF. On cadmium transport retardation , all dietary fibers except $\alpha$-cellulose had the retarding effects and PSDF showed the greatest effect which was followed by PIDF and CMC, The extracted fibers showed higher retarding effect on Cd transport than glucose and bile acid transport, and dietary fibers from persimmon peels showed higher retarding effects than those from dried jujubes.
