Studies on the effect of heat on milk

Abstract
Heat caused the disappearance by volatilization of 20 % or more, according to the duration of the heating, of the total iodine of separated milk. The ratio of diffusible to non-diffusible iodine was the same after heating as before. Of the total iodine of separated cow''s and goat''s milk, 83% was diffusible. Ultrafiltration (Thiessen apparatus) and dialysis methods were used.
