Abstract - Milk can be considered as an important source of vitamins for newborns, children and adults. In light of recent findings, it has been shown that a normal daily consumption can cover the total needs in vitamin B1, B2, B6, B12, pantothenic acid, inositol, and can provide a large part of needs for vitamins A, D, biotin and ascorbic acid.
The facts concerning the stability of each of these vitamins under the influence of various thermal treatments and of light radiation which is substantial during storage, have been assembled. The tables resume the values found by numerous authors.
Photo-oxidation and the causes of the appearance of foreign tastes have been discussed. Various methods for avoiding photo-oxidation and vitamin depletion have been envisaged. They involve a cold chain, a "black chain", elimination of oxygen disolved in the milk, improvement in the thermal treatment utilizing "biodegradable", antibiotics, photo-protection by vitamin synergism
