AI Technical Summary
Technical Problem
Existing methods for preparing crystalline D-psicose result in a wide size distribution of crystals, which affects the uniformity and efficiency of the crystallization process.
Method used
A method combining evaporative crystallization, crystal regulation, and cooling crystallization is employed, utilizing specific cooling intervals and rates based on D-psicose's metastable zone curves, with optimized crystal seed sizes and controlled solid mass content to achieve a narrow size distribution.
Benefits of technology
The method produces crystalline D-psicose with a narrow size distribution, high yield, and improved crystal morphology, reducing energy consumption and production costs while maintaining high purity.
