Study on preparation of slowly digestible starch by Pullulanase
摘要
Abstract
Using potato starch as raw material,pullulanase was chosen to prepare slowly digestible starch (SDS).The effects of enzyme amount,enzynolysis time,concentration of starch and refrigeration time were investigated by single factor tests.Subsequently,Box-Behnken design was used to investigate the effects of four factors on SDS mass concentration.The optimum combination was obtained by Design Expert 8.05 software and response surface analysis.The results showed that the optimum process conditions were as follows:enzyme amount 160U/mL,enzynolysis time 8.5h,concentration of starch 10％,refrigeration time 3d.Under the above optimized conditions,the mass concentration of SDS was 18.3％.The results provided a theoretical basis for the development of slowly digestible starch.关键词
