气相二氧化硅在粒径测试中的应用

摘 要：
葡萄糖（Dextrose），又称右旋糖，遇水易发生结晶，微溶于乙醛，不溶于和芳香烃葡萄糖是生物代谢中的关键中间物质，食品工业用作甜味料（甜度约为蔗糖74%）葡萄糖的粒径大小和形状可直接影响到食品添加剂的口感和保质期，由于其物质密度很低，通常的粒径分析方法不易得到准确的结果，在葡萄糖粉末中，加入气相二氧化硅作为分散剂，用RETSCH TECHNOLOGY公司的CAMSIZER粒径及形态分析仪进行粒径大小和形态的分析，可以得到准确而直观的结果
Glucose（Dextrose）is easy to be crystallized and dissolve in the acetaldehyde while it is not to be dissolved in ether and arene. The glucose is a key intermediate relating to metabolism. it is used to be sweet flavor in food industry. The particle size and shape of glucose can influence the tasting of food and quality period. Because of its low density, it is very difficult to analysis it with sieve and laser instruments. Mixed with the gas-silicon and using CAMSIZER can help to get the correct results and images.
