摘 要： 葡萄糖（Dextrose），又稱(chēng)右旋糖，遇水易發(fā)生結(jié)晶，微溶于乙醛，不溶于和芳香烴葡萄糖是生物代謝中的關(guān)鍵中間物質(zhì)，食品工業(yè)用作甜味料（甜度約為蔗糖74%）葡萄糖的粒徑大小和形狀可直接影響到食品添加劑的口感和保質(zhì)期，由于其物質(zhì)密度很低，通常的粒徑分析方法不易得到準(zhǔn)確的結(jié)果，在葡萄糖粉末中，加入氣相二氧化硅作為分散劑，用RETSCH TECHNOLOGY公司的CAMSIZER粒徑及形態(tài)分析儀進(jìn)行粒徑大小和形態(tài)的分析，可以得到準(zhǔn)確而直觀的結(jié)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. 關(guān)鍵詞：葡萄糖氣相二氧化硅粒徑形態(tài)CAMSIZER Key words：Dextrose, Gas phase silicon, particle size, shape, CAMSIZER 萊馳科技Camsizer P4 動(dòng)態(tài)圖像法粒度儀
