Sublimated mare's milk was stored with and without antioxidants during one year. The antioxidants quercetin and bisalcophen were introduced before drying in a dose of 0.02% relative to milk fat. Lipid, fatty acid composition and lipid peroxidation (LPO) parameters (diene and triene conjugates, total lipid oxidation) were studied immediately after drying and after 3, 6, 9 and 12 months of storage. No significant changes were detected in lipid, fatty-acid composition and LPO rate after 3 months of dried milk storage without additives. Significant deterioration of lipid, fatty-acid composition, increase of LPO and oxidation of milk were recorded after 6 months. Addition of quercetin and bisalcophen promoted stabilization of fatty-acid composition and prolonged the term of sublimated mare's milk storage.
