1. The average nicotinic acid, pantothenic acid, choline andbiotin content of fresh milk was found to be 0.91 mg., 3.1 mg.,149 mg. and 47.1 µg. per liter, respectively.
2. Inthe processing of irradiated evaporated, dry skim or drywholemilk, the data show no significant losses in the contentsofnicotinic acid, pantothenic acid, choline and biotin withthepossible exception of the slightly lower biotin contentof dryskim milk.
3. The possibility of small and probably insignificantprocessinglosses cannot be definitely excluded because theraw milk sourcesof the different types of milk tested werenot identical, becauseof the variability of the data, and becauseof the limitationsin accuracy of the microbiological methodsused.
