Vitamins react to the duration of the thermal treatment and not to the temperature. If we boil the milk at home at a temperature of 100 degrees for about 15-20 minutes, most of the vitamins are destroyed. Scientific studies have proved that processed and packed milk is safer for consumption and best preserves vitamins. Unprocessed or raw milk can contain dangerous bacteria which are not destroyed during boiling. Moreover, boiling destroys most of the nutrients in the milk. Processed and packed milk, which is safest for consumption and preserves vitamins, needs standard procedures and time for processing and distribution. It also requires investments for the best scientific technology and a continuous support of research and preservation methods.
