The Occurrence of Gamma Tocopherol in Corn Embryo Oil

Abstract

A method and apparatus for collecting milk samples directly from the cow''s udder in a CO2 atmosphere without exposure to light or air are described, also a method of preparing a stable titrating soln. of 2,6-dichlorobenzenoneindophenol. Titration of untreated milk samples collected by this method and of samples treated with H2S gave ascorbic values in close agreement, indicating that the ascorbic acid in milk collected in this manner was in the reduced form. No adsorption of ascorbic acid by the milk proteins was demonstrated.
