The Preparation and Adsorbing Capability of Porous Starch from Rice
摘要
Abstract
To prepare porous starch of rice and measure its adsorption performance.[Method] With immersion home-made rice starch as raw material,adopting saccharifying enzyme,compound of alpha amylase enzyme hydrolysis to prepare porous starch.With oil absorption rate,specific pore volume and the slow release of orange essence performance as indicators to evaluate rice porous starch.[Result]The best digestion process conditions were as follows:reaction temperature 35 ℃,time 16 h,pH 4.5,ratio of saccharifying enzymealpha and amylase enzyme 10∶1,the substrate concentration 0.2 g/ml,grain size 40 mesh.Under this condition,the preparation of porous starch of rice oil absorption rate is the highest,up to 58.14％.[Conclusion] Porous starch of rice have higher oil absorption rate,larger specific pore volume and good slow release of orange essence,which can be used extensively as adoption carrier for many substances,providing an effective way for comprehensive utilization of rice resource and promoting industrial production of porous starch.关键词
