【Abstract】 After the correlative crystallization kinetic models were selected,the moment transforming,one of the intermit- tent dynamic methods,was adopted to determine the crystallization kinetics of fine granular vitamin C.The kinetic parameters under the experimental conditions were obtained by using the least square method for the multivariate linear regression,and the reliability of the kinetic models was validated experimentally.In addition,the influencing factors of the cooling crystallization process of fine granular vitamin C were analyzed.更多还原
