Optimization of Crystallization Process of D-allulose
In order to improve the crystallization process of D-allulose,the mesh distribution and crystal morphology of D-allulse after crystallization were used as indicators to optimize the concentration of D-allulose,the amount of seed crystal,the amount of evaporated water,the stirring speed and the cooling frequency.The results showed that the optimal crystallization process of allulose was concentration 76%,seed addition 1.4%,evaporation water 83 g·h-1,stirring speed 16 r·min-1,and cooling frequency 0.4℃·h-1.Under this condition,the crystallization yield was high and the crystal form was good.
