Abstract
Phosphorylated acylglycerols and their salts containing nitrogen inhibit the autoxidation of rapeseed, soybean, sunflowerseed, and hydrogenated rapeseed oils, similarly as natural soybean or rapeseed phospho‐lipid concentrates (lecithins). The activity is moderate at low concentration levels (0.02–0.10%) but well pronounced at higher levels (0.5–2.0%), the protection factor being proportional to the concentration of phospholipids. Ammonium salts are more active than lysine and arginine salts which are more active than free phosphatidic acids. Zinc salts have only very low activity, and calcium and sodium salts are inefficient. The activity depends on the quality of oils, and in lesser degree, on the composition of phospholipids.
