标准范围

This part of ISO 18363 describes a procedure for the indirect determination of 3-MCPD esters (bound3-MCPD) and possible free 3-MCPD after alkaline catalysed ester cleavage and derivatization withphenylboronic acid (PBA). Furthermore, this part of ISO 18363 enables the indirect determination ofglycidyl esters (bound glycidol) under the assumption that no other substances are present that reactat room temperature with inorganic chloride to generate 3-MCPD.This part of ISO 18363 is applicable to solid and liquid fats and oils. Milk and milk products (or fatcoming from milk and milk products) are excluded from the scope of this part of ISO 18363.
