标准摘要
[中文适用范围]： 该方法包括将测试部分溶解在氯仿中，用乙酸溶液从该溶液中萃取游离甘油，用过量的高碘酸溶液氧化氯仿溶液中的1-单甘油酯，加入碘化钾并滴定所释放的甘油三酯。 用硫代硫酸钠标准滴定溶液加碘。 用过量的高碘酸溶液氧化水溶液中的游离甘油，加入碘化钾，用硫代硫酸钠标准滴定溶液滴定释放出的碘。 [外文原描述]： The method consists in dissolving of a test portion in chloroform, extracting of free glycerol from this sulution with acetic acid solution, oxidizing of 1-monoglycerides in the chloroform solution by an excess of periodic acid solution, adding of potassium iodide and titration of the liberated iodine with a sodium thiosulfate standard volumetric solution. Oxidation of free glycerol in the aqueous solution by an excess of periodic acid solution, adding of potassium iodide titration of the liberated iodine with a sodium thiosulfate standard volumetric solution.
英文名称Animal and vegetable fats and oils — Determination of 1-monoglycerides and free glycerol contents
