title: Lipolysis of triglycerides of human milk during storage at low temperatures: a note of caution.
abstract: Human milk samples were divided at collection and stored at -70 degrees C or -20 degrees C, or extracted immediately with organic solvent, to compare lipid class composition. Storage at -20 degrees C was not satisfactory for maintaining milk lipid composition, for it resulted in hydrolysis of triglycerides and the appearance of free fatty acids.
