Study On The Technics Conditions And Characteristics Of Citrus Dietary Fiber

The technics conditions and characteristics of dietary fiber were studied with materials of the pomace of citrus.Enzyme and microwave-chemical were adopted to made DF.The residue of bean curd, wheat bran, peanut bran, pomace of pear and plantain also were adopted to made DF. Component and pHysical-chemical characteristic were mensurated and their pertinence also was analyzed.All this data from experimentations provided theoretic gist for the compositive use of citrus pomace. Main contents and results of the test are as follows:1 . The concentration of cellulase and time of reaction affected markedly the radio of SDF to TDF,but the ratio of liquor to material and temperature did indistinctively ,The orthogonal test was performed to determine the optimum technics for the DF from the citrus pomace adopting cellulose. The result indicated that the dregs were marinated in 3.75ug/ml of cellulase,60:1of the ratio of liquor to material ,40'C for 150min.The concentration of snail enzyme and the temperature affected markedly the radio of SDF to TDF, but the ratio of liquor to material and time did indistinctively, The result of the orthogonal test indicated that the pomace were marinated in 1.5ug/ml of snail enzyme, 25:1of the ratio of liquor to material,30'C for 240min.The concentration of HCL and output power of microwave affected markedly the radio of SDF to TDF, but the ratio of liquor to material and time did indistinctively.2. The result of the orthogonal test indicated that the pomace were marinated in 0.06moml/l of HCL, 20:1of the ratio of liquor to material ,550w for 210s. The concentration of NaOH affected markedly and fearfully the radio of SDF to TDF and the ratio of liquor to material affected markedly the radio, but output power of microwave and time did indistinctively. The result of the orthogonal test indicated that the pomace were marinated in 0.06moml/l of NaOH, 60:1of the ratio of liquor to material ,750w for 150s.3. The content of TDF in all citrus DFare all above 90%, the higher one is TDF from snail enzyme and the next one is TDF from cellulase and microwave-HCl,The content of SDF between 41% to 63%, and the highest one isTDF from microvave-NaOH.The higher one is microvave-HCL,their ratio of SDF to IDF was 1.53 and1.97 separately,The content of IDF in all IDF sample is between 76%～94%,and the highest one is IDF from microwave-NaOH and pectic enzyme4. The WHC,EXP of citrus DF is higher than material and the result is between 6.5g/g to 11.10g/g,and 6.3ml/g to 9.3ml/g.The highest one is from microwave-NaOH ,but that is 5.08g/g and 6.30ml/g from citrus pomace, The capacity that DF adopt fatty acid is higher than citrus pomace except microwave-HCl.The most strong capacity to exchange cation is TDF that is from microwave-NaOH, and CAC is IDF from microwave-NaOH,NAC is IDF from snail enzyme,BAAC is IDF from cellulase.5. The data that have effect on character of dietary fiber is nalysised by Factor Analysis.the result is used to estimate the character of dietary fiber ,we found that the dietary fiber from citrus pomace and plantain is better than others and the relativity between the component and pHysica chemistry character is distinct or fearfully distinct.6. There are large number of flavones specially naringenin and hesperidin in DF from citrus pomace .There is most content in the IDF from cellulase and the content of flavones is 100.12g/kg.The other way round there is least content in the TDF from microwave-NaOH with 53.61g/kg,.The content of flavones of citrus pomace is 86.22g/kg.The resut indicated that the infection from cellulase is lesser than others.
