Vitamin A, carotene, thiamin, riboflavin, ascorbic acid and vitamin B-12 were estimated in milk before and after flash sterilisation at 85o, 125o, 135 degrees or 145oC for 3 to 4 see by direct injection of steam or heat transfer through the wall of the container. At 145 degrees 4-5% of the vitamin A was lost. At over 100 degrees 10 to 17% of carotene was lost, slightly more by steam injection than by the other method. Loss of thiamin was only 5 to 8% and that of riboflavin 1 to 2.5%.
