摘　　要：用熔融共结晶法制备了赤藓糖醇-蜂蜜固态复配产品,应用TG-DSC、XRD、SEM、FT-IR等对其结构与性能进行了表征分析;结果表明：赤藓糖醇-蜂蜜固态复配产品为共晶体,保有蜂蜜的天然成分,单因素实验表明,晶种的加入量以及粒度分布、降温速率是影响赤藓糖醇-蜂蜜共结晶过程的产品粒度分布的关键因素,当加入晶种的粒度为170-200目,加入量为1-3wt%,降温速率控制在0.5-10℃/min时,得到的赤藓糖醇-蜂蜜共晶体产品中40-60目的晶体占总质量的90%以上,无需额外干燥工序时共晶体产品的含水量小于0.5wt%,结晶度不小于90%。Melt co-crystallization process was adopted to produce meso-Erythitol honey compounds ; the structure and properties had been characterized and analyzed by using TG-DSC, XRD, SEM and FT-IR. The results indicated that the compound product of meso-Erythitol with honey is co-crystal. According to the single factor experiments, seeding load with its CSD and cooling rate can affect the product CSD of co-crystal products of honey meso-Erythitol. When the process parameters of co-crystallization of meso-Erythitol with honey was 1 - 3wt % of seeding load, 170 - 200 mesh size, cooling rate of 0.5 - 10℃/min, the final products of 40 - 60 mesh crystals were more than 90%. The water content of the eutectic product is less than 0.5 wt% without additional drying step, and its crystallinity was no less than 90% .
