This document specifies a method to determine the saturated monoglyceride content in Fatty Acid Methyl Esters (FAME). This method only identifies and quantifies the following saturated monoglycerides: 1-C16:0, 2-C16:0 and 1-C18:0. The total saturated monoglyceride content is calculated by the summation of the contents of these three saturated monoglycerides. The precision has been established for FAMEs having saturated monoglycerides in the (200 to 1 500) mg/kg range.This method is not suitable for FAME produced from or containing coconut and palm kernel oil derivatives because of overlapping of various peaks.NOTEThis Standard determines only three saturated monoglycerides, i.e. 1-C16:0, 2-C16:0 and 1-C18:0. FAMEs can contain also other saturated monoglycerides such as 1-C17:0, but these are generally much lower than the three targeted saturated monoglycerides and are therefore not included in the Standard's scope.WARNING - The use of this standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose.
