Preservation of vitamins A, E, C, B6, B1, B2, B5, Bc was studied during preparation of dried special-purpose milk mixtures ("Solnyshko", "Inpitan", enpits, low-lactose mixtures) and after storage ("Inpitan", and low-lactose mixtures) during 1 year at 4 and 18 degrees C. It has been established that vitamins A, E and C are most subjected to deterioration during production of dried special-purpose mixtures, their losses comprise 17-47, 18-43, 13-41%, respectively. B2 and B5 were most resistant in the process of the mixture production. No significant losses of vitamins were recorded during storage of "Inpitan" and low-lactose mixtures.
