Soybean Water-soluble Polysaccharide Capsule As Phytase-coating Material Applied Research

With biology, molecular biology technology, and other basic subjects and the rapid development of applied technology, an efficient, strong-specific physiological function of the biological agents has become a new focus of research and development of feed additives, the use of its production scale is continually expanding. Phytase use of genetic engineering is a kind of fermentation technology in a highly efficient system of enzymes. But in the feed industry in the application subject to the restrictions on processing high-temperature process, the activity has suffered serious losses. Microencapsulation technology is more mature application of a biological prote-ction technology, used in animal feed industry in isolation, the protection of environm-entally sensitive components, such as vitamins, protease, probiotics and other biological active ingredients and application of the environmental impact of the material. In aquatic feed aqu-atic animals also applied to the weaning food protection. Acid and polysaccharide-protein coagulation is a micro-biological capsule of the commonly used methods, its simp-le preparation method, coating effects of good, clear protective effect.By using water-soluble gelatin and soybean polysaccharide recov-ery rally prepared phytase micro-capsules, and powder point polysaccharide absorption and curing alginate microcapsules ph-ytase prepared by the effects of high temperature for comparison will be Since the qu-estion of water-based polymer modified soybeans and soybean polysaccharides and wa-ter-soluble polysaccharide goods coating effects were compared. Specific research results are as follows:(1) water-soluble gelatin and soybean polysaccharide rehabilitation pool, water-soluble gelatin and soybean polysaccharide-unite the appropriate ratio of 2:1 mixed quality, ac-id-base strength, 3.5-4.4; appropriate concentration of salt ions for the following 50 mM。(2) different water-soluble polysaccharide soybean coating method and the results of comparison, since the study mentioned modified water-soluble polysaccharide soybe-an and soybean products water-soluble polysaccharide as a micro-capsule wall material applications. Results were compared to its high temperature, since modified to water-soluble polysaccharide soybeanⅡ, micro-capsules of the phytase package was effective, high temperature of goods is better than water-soluble polysaccharide soybean. (3) different methods of coating, the package was drawn better way. Soybean water-solubl-e polysaccharide compared with the gelatin-coagulation and curing alginate, starch pol-ysaccharides prepared by adsorption microcapsules-sik The high temperature characteri-stics of acid. The results showed that water-soluble gelatin and soybean polysaccharie rehabilitation pool prepared by Microcystis good role phytase high temperatures, high temperatures have better protection. Preparation phytase can be used as micro-capsule-s of the wall material.
