标准摘要
[中文适用范围]: 本国际标准规定了植物脂肪和油中二酰基甘油异构化程度的测定方法。1,2-二酰基甘油在储存期间或由于酸催化反应会转化为更稳定的1,3-异构体。1,2-二酰基甘油的质量分数可用作植物脂肪和油的质量标准。 [外文原描述]: ISO 29822:2009 specifies the determination of the degree of isomerization of diacylglycerols in vegetable fats and oils. 1,2-Diacylglycerols are transformed to the more stable 1,3-isomers during storage or due to acidic catalysed reaction. The mass fraction of 1,2-diacylglycerols can be used as a quality criterion for vegetable fats and oils.
英文名称Vegetable fats and oils — Isomeric diacylglycerols — Determination of relative amounts of 1,2- and 1,3-diacylglycerols
