近年来,高纯钠基膨润土被日本等国家应用于生产减肥食品,因其具有高膨胀性,食用后产生饱腹感,从而可减少其他食物的摄入量。本研究以山东潍坊钙基膨润土为研究对象,对其进行原料分析,以其为主要原料制备减肥食品用膨润土并检验其膨胀容。结果表明:潍坊钙基膨润土改型后经二次提纯可获得高品质的减肥食品用高纯膨润土,所制备的膨润土具有高的膨胀容,符合蒙脱石国家药品质量安全标准要求。
In recent years, high-purity sodium bentonite is used in countries such as Japan for the production of diet foods because of its high expansibility and consequent satiety after consumption, thereby reducing the intake of other foods. In this study, calcium-bentonite in Weifang, Shandong Province as the research object, its raw material analysis, as its main raw material for the preparation of bentonite diet food and test the swelling capacity. The results showed that high purity bentonite with high purity bentonite could be obtained by secondary purification of calcium bentonite modified by Weifang. The bentonite prepared by this method has high swelling capacity and meets the requirements of national quality and safety standards for montmorillonite.
