籼米多孔淀粉制备及微藻油DHA微胶囊化的研究
Study on porous starch preparation and adsorption micro-algae oil DHA microcapsules
摘要
Abstract
In order to optimize preparation conditions of rice porous starch,the effect of hydrolysis temperature,pH,reaction time,enzyme ratio of glucoamylase and α-amylase were investigated by setting micro-algae oil DHA adsorption ratio as an index.Results indicated that the optimum conditions were enzyme ratio 8:1,pH4.5,temperature 45℃,hydrolyzed 12 hours.Using the porous starch absorbed micro-algal oil as core materials,the spray-dried microcapsules had an encapsulation efficiency of 92.08%,a moisture content of 3.78%,and the two values were both according with basic requirements of milk powder.关键词
