【摘要】：目的:对喷雾干燥法生产的维生素E干粉进行质量研究,为维生素E干粉产品质量控制和应用提供科学依据。方法:对10个批次喷雾干燥法生产的维生素E干粉进行物理性质、化学性质和产品应用性评价,以外观、产品长期和加速稳定性、粒度分布、水分活度、休止角、松紧密度、冷水溶解性及漂油情况、水溶液及高糖高酸体系稳定性为指标,对喷雾干燥法生产的维生素E干粉的质量进行详细的考察。结果:喷雾干燥法生产的维生素E干粉为白色至类白色流动性粉末,无明显异物存在,加速稳定性试验条件下储存6个月和长期稳定性试验条件下储存36个月外观无明显改变;维生素E干粉的休止角为35.23±2.40°,水分活度为0.339±0.043,松密度为0.431±0.018g/cm3,紧密度为0.502±0.022g/cm3,粒度主要分布在60~100目之间;在加速稳定性试验条件下储存6个月的含量保留率为99.97±0.12%,长期稳定性试验条件下储存36个月的含量保留率为99.98±0.32%;维生素E干粉在冷水呈小蝌蚪状拖尾下落,并且在冷水中均匀分散,搅拌均匀后无结团、无漂油;维生素E干粉在水溶液和高糖高酸体系中稳定性良好。结论:维生素E干粉冷水分散,稳定性好、应用性能优异。
[Abstract]:Objective: vitamin E powder on spray drying method for the production of quality research, provide scientific basis for vitamin E powder product quality control and application. Methods: vitamin E powder production of 10 batches of spray drying method for physical properties, chemical properties and application of the evaluation to the appearance of products, long-term and accelerated stability. The particle size distribution, water activity, angle of repose, elastic density, water solubility and floating oil, water solution and high sugar and acid stability of the system as the index, the quality of vitamin E powder on spray drying production were investigated in detail. Results: vitamin E powder spray drying method for the production of white to white flow powder, no foreign body exists, the accelerated stability test under the condition of storage test conditions for 6 months and long-term stability under storage for 36 months without obvious changes in appearance; vitamin E powder is 35.23 angle of repose Plus or minus 2.40 degrees, the water activity was 0.339 + 0.043, bulk density was 0.431 + 0.018g/cm3, close to 0.502 + 0.022g/cm3. The size is mainly distributed in the 60~100 mesh; storage content for 6 months in the accelerated stability test under the condition of the retention rate was 99.97 + 0.12%, long term stability test content stored under 36 months retention the rate is 99.98 + 0.32%; vitamin E powder showed a small tadpole tail drop in cold water and in cold water evenly dispersed, no cake evenly, no bleaching oil; vitamin E powder in good water solution and high sugar acid system stability. Conclusion: vitamin E powder cold water dispersion, good stability and application performance excellent.
