Overview
EN ISO 11701:2009 is an internationally recognized standard developed by CEN and ISO for the quantitative determination of phospholipid content in lecithins derived from vegetable fats and oils. The standard specifies a validated method that uses high performance liquid chromatography (HPLC) with a diol column and a light-scattering detector. This analytical approach ensures accurate identification and quantification of individual phospholipids, supporting quality control and compliance in the food, feed, and lecithin processing industries.
