摘　　要：三氯蔗糖的生产工艺经过长期发展已逐渐成熟,但如何提高三氯蔗糖的产量和生产效率,仍需不断探索。提高三氯蔗糖产量的关键,在于反应后的结晶及提纯。课题主要通过改变原有方法的条件,引入超声,寻求更利于三氯蔗糖结晶且经济的结晶路线,得到符合市场需求的三氯蔗糖颗粒。结果表明:在超声波的作用下,三氯蔗糖的成核速率快速提高,晶体数目稳定、粒度在一定范围内颗粒较为均匀。超声处理可控制三氯蔗糖粒径在110μm,得到更细腻、纯度更高的三氯蔗糖。After years of development,the production process of sucralose has matured considerably.However,improving the yield of sucralose remains an area of ongoing research.The key to increasing sucralose yield lies in post-reaction crystallization and purification.This study aimed to improve the crystallization process of sucralose by introducing ultrasound under modified conditions,seeking a more economical crystallization route for that generates sucralose granules meeting market demands.The results demonstrated that under the influence of ultrasound,the nucleation rate of sucralose rapidly increased,stabilizing the number of crystals with a consistent particle size range and uniform granule distribution.Therefore,ultrasonic treatment could effectively control the particle size of sucralose at 110μm,resulting in a finer and purer sucralose product.
