糖果中水分检测方案(卡氏水分测定)

糖果中水分含量的测定 应用资料使用卡尔费休试剂进行水分滴定是世界上最可靠的水分测量方法。该程序在许多官方标准中被采用，作为GB，ISO，ASTM，DIN，BS和JIS中规定的测试方法。在此应用中，我们根据GB/T 6283通过KF滴定的直接方法测量样品中的水分含量。将溶解在溶剂中的糖果在低于45℃的温度下加热以提取水含量并测量。KVX01514-enLK-MKYOTO ELECTRONICSMANUFACTURING CO.，LTD. Application Memo Moisture Determination in Candy Industry Food and beverage Instrument Karl Fischer moisture titrator Measurement method Volumetric titration (Direct method) Standards GB/T 6283， JIS K0113， ASTM E203， ISO 760 1.Overview Moisture titration with Karl Fischer reagent is the most reliable moisture measurement methodin the world. The procedure is adopted in many official standards as test method specified inGB， ISO， ASTM， DIN， BS and JIS. Here in this application， we measure water content in the sample by direct method of KFtitration according to GB/T 6283. The candy dissolved in the solvent is warmed at less than 45°℃ to extract the water contentand measure. 2.
