ISO 29822:2009规定了植物脂肪和油中甘油二酯异构化程度的测定。1,2-二酰基甘油在储存期间或由于酸性催化反应转化为更稳定的1,3-异构体。
1,2-二酰基甘油的质量分数可用作植物油脂的质量标准。
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.
