Effect of High-Temperature-Short-Time Pasteurization on the Ascorbic Acid, Riboflavin and Thiamin Content of Milk

Abstract
Twenty lots of milk were pasteurized at irregular intervals during 18 months by the high-temp .-short-time process. The milk was assayed for ascorbic acid, riboflavin, and thiamin just before and immediately following pasteurization. The av. values obtained were 16.4 mg. per liter of ascorbic acid for the raw, and 16.6 mg. for the pasteurized milk; 1.5 mg. per 1. of riboflavin for the raw, and 1.5 mg. per 1. for the pasteurized milk; and 0.36 mg. per 1. of thiamin for the raw, and 0.35 mg. per 1. for the pasteurized milk.
