Abstract
With epichlorohydrin as crosslinking agent,potato crosslinked starch was prepared.Influences of epichlorohydrin dosage,sodium hydroxide dosage,reaction temperature and reaction time were researched using orthogonal test,and optimum technological condition was determined.The digestibility was also studied.The results showed that the optimum determination condition of crosslinked starch was as follows:wavelength 485nm,temperature 100℃,time 30min,glucose concentration 0 ~ 80μg/mL,regression equation was y=0.0044x-0.005,R2=0.9988,and the sample color was stable within 2h.The factors influencing order was epichlorohydrin dosage,sodium hydroxide dosage,reaction temperature and reaction time.The optimal preparation condition was as follows:50g potato starch as material,epichlorohydrin dosage 1.00mL,sodium hydroxide dosage 0.75g,temperature 50℃,time 6h.under the condition above,the digestibility of crosslinked starch decreased by 13.7% ~34.5% than raw starch,negative correlation with crosslinking degree.关键词
