Preparation For Malus Asiatica Dreges Chewing Flakes Of Dietary Fibre

In this study,the malusa siatica dregs was taken as raw material.First,enzymolysis was separately applied with alpha amylase,protease papaya,cellulose enzyme and orthogonal optimization was applied too.Second through the comparison of properties of dietary fiber,the appropriate material granularity was filtered out.Third,decolorization was applied,after decoloring,samples were modified by ultrahigh pressure,while the microstructure of the sample between before and after the treatment of ultra-high pressure were compared.At last,using high-quality dietary fiber as the main raw material,the formula of chewing flakes chewable was optimized.(1)Optimal conditions of enzymolysis with alpha-amylase on malus asiatica dregs dietary fiber was below: the dosage of cellulose enzyme was 750 u/g,reaction time was 80 min,the enzymolysis temperature was 50?,pH was 7.5,at this time,SDF/TDF was 13.76%;optimal conditions of enzymolysis with protease papaya on malus asiatica dregs dietary fiber was below: the dosage of cellulose enzyme was thirty thousand u/g,reaction time was 90 min,the enzymolysis temperature was 40?,pH was 7.5,at this time,SDF/TDF was 13.45%;optimal conditions of enzymolysis with cellulose enzyme on malus asiatica dregs dietary fiber was below: the dosage of cellulose enzyme was 50u/g,reaction time was 80 min,the enzymolysis temperature was 45?,pH was 4.6,at this time,SDF/TDF was 18.86%.So extraction of dietary fiber with the cellulose enzyme was the best,SDF/TDF was maximum.(2)When the shattered mesh of raw material was less than 100 meshes,the water retention capacity,the force of expansion and the force of holding oil raised with the increase of mesh;When the mesh is greater than 100 meshes,he water retention capacity,the force of expansion and the force of holding oil declined;The larger the mesh was,the greater repose angle and slip angle would be;The adsorption of nitrite ion was the strongest at the shattered mesh of 100 meshes;SDF increased significantly between the 40-100 meshes,More than 100 meshes,soluble dietary fiber increased slightly.According to the practical production,considering to the maximum extent of the use of raw materials,the granularity of raw material was determined to be 100 meshes,At this time the SDF/TDF was 18.92,increased by 0.64%.(3)The optimal technological conditions of decolorization was below:decoloring temperature was 65?,the density of H2O2 was 3%,liquid ratio was 1:10,pH was 8,decoloring time was 1.5h,at this time,the absorption value was 2.405,reaching its maximum,Namely decoloring worked best.After decoloring,the quality of product had been improved,the water retention capacity,the force of holding oil and the force of expansion respectively had a certain improvement.Solubility of soluble dietary fiber was also better under the environment close to human body.(4)The optimum conditions for modification through ultrahigh pressure was below: liquid ratio was 1:23,the pressure was 280 MPa,reaction time was 16 min,at this time the average SDF/TDF was 22.04%,increased by 3.12%.Scanning electron microscope picture,infra-red spectrogramand the X ray diffraction figure of the sample between before and after modification were rather different,and the saise of SDF content had a great relationship with it.(5)The formulation of chewing flakes after optimization was below:the content of DF was 28%,the content of sour agent was 5%,the content of sweeting agent was 19%,the content of sorbierite was 3%,carboxymethylcellulose sodium was 14%,hard acid magnesium 0.4%,milk powder5%,Vc 2 % and the rest was filled with dextrin.
