The Effects And Comparison Of Soybean Dregs And Soybean Hulls Dietary Fiber On Blood Lipid And Anti-oxidation Of Hyperlipidemia Mice Caused By Trans-fatty

In this study， use d soybean dregs dietary fiber(SDF， IDF， S DF：IDF＝1:3) and soybean hulls dietary fiber(SDF， IDF， S DF： I DF＝1:3)，analysed the composition of monosacc haride； determined and comparedtheir properties， including water holding capacity， oil absorptioncapacity， swelling capacity， nitrite adsorption capacity， cholesterolabsorption， scavenging ability， viscosity and the capacity of cationexchange； studied and compared the effect s of blood lipid andanti-oxidation of hyperlipoidemia cause d by trans-fatty．(1) Study on the monosacc haride composition of of soybean dregsand soybe an hulls dietary fiberThere wer e xylose，arabinose，fructose，mannose，glucose，galactosein the soybean dregs and soybean hulls dietary fiber． But themonosacc haride composition of of soybean dregs and soybean hullsdietary fi ber were different． In soybean dregs dietary fi ber， there wer eless branched chai n of pect in kind polysaccharide， in soybean hullsdietary fi ber， ther e were mainly high branched-chain of pectin kindpolysaccharide． And glucose was mainly from the degradation o fcellulose．(2) The s tudy on the proper ties and comparison of all kinds ofsoybean dregs and s oybean hulls dietary fiberWater hol ding capacity，oil absorption capacity，swelling capacity，nitrite adsorption capacity etc． cholesterol absorption were studied，eesults showed that water holdingcapacity， oil absorption capacity，swelling capacity of the mi xed soybe an dregs dietary fiber was6.41%，11.04%a nd9.22%higher than that of SDF， and16.56%，21.59%and 35.93tha n that of I DF， the mi xed soybean hulls dietary fiber was5.10%，15.81%a nd0.53%higher t han that of SDF， and21.94%，27.01%and28.28%hi gher than that of I DF， and these three kinds of s oybean dr egsdietary fiber are respectively better than that of soybean hulls dietaryfiber in these three properties；Nitrite absorption capacity was stronger inpH2than that in pH7， on both conditions， the sequence of nitriteadsorption capacity was mi xed dietary fiber>IDF> SDF， the nitriteabsorption capacity of soybean dregs dietary fi ber are better than that ofsoybean hulls dietary fiber， cholesterol absorption capacity was strongerin pH7than in pH2， the cholesterol absorption capacity of soybean dregsdietary fiber are respectively30.92%，10.44%a nd0.22%higher than thatof soybean hulls dietary fiber.in pH2， and respectively26.37%，10.22%and1.38%higher than tha t in pH7， All die tary fibers have st rongscavenging ability， the sequence of scavenging ability was mixed dietaryfiber>SDF> IDF.and soybean hulls，are better than that of soybeandregs’． sample viscosity increased gradually with the concentrationincreasing．On the same concentration，SDF vis cosity was highest, mi xe ddietary fiber took s econd place， and I DF least； IDF’s cation exchangecapacity are poor than that of SDF’s and the mixed’s．（3）The effects and comparison of soybean dregs and soybean hullsdietary fi ber on blood lipid and anti-oxidation of hype rlipidemi a micecaused by trans-fattyThe ATM (11%TFA) resulted in hyper lipidemia mice， which wereadministrated orally with soybean dre gs and soybean hul ls dietary fiberof low， moderate and high dose． The rusults showed tha in the conditionof the IDF of s oybean dregs dietary fiber， the low dosage could obviosl yenhance TAOC，the moderate decrease TG，LDL-C and NO，enhance SODand TAOC，the hi gh decrease TC， T G，LDL-C，M DA and NO， enhance HDL-C， SOD and TAOC， i n the condition of the IDF of soybean hullsdietary fiber，the moderate could obviously decrease TG，LDL-C a nd NO，the high could make all eight index change obviously; in the condition ofthe SDF of soybea n dregs dietary fiber， the low dosage could obviosl yenhance TAOC， t he moder ate decrease TC， TG， LDL-C and NO，enhanceHDL-C， S OD and T AOC， the high could make all eight indexchange obviously;in the condition of the SDF of soybea n hulls dietaryfiber， the low dosage could obviously MDA and NO， the moderatedecrease TC，T G，NO an d MDA，enhance HDL-C，TAOC and SOD，thehigh could make all eight index change obviousl y； in the condition of themi xed soybean dregs dietary fiber， the low dosage could obviouslydecrease LDL-C and NO， enhance SOD and TAOC， the moderate and thehigh make all eight index change obviously，in the condition of the mixedsoybean hulls dietary fiber， the low dosage coul d obvious ly decrease TCand NO，the moderate decrease TC，T G，LDL-C a nd NO，enhance HDL-C，the high c ould ma ke all eight index change obvi ously； In a word， theeffects of SDF:I DF(1:3) were better than SDF on reducing blood lipid andanti-oxidation capacity， but had little difference， both were better thanIDF． Bot h soybean dregs and soybean hulls diet ary fiber have effe cts onreducing blood lipid and anti-oxidation capacity,however，different indexcan influe nce blood lipid and anti-oxidation capacity differ ently．...
