The Vitamin A And Carotene Content Of Nebraska Butter, I. L. Hathaway, H. P. Davis
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The vitamin-A, carotene, fat and moisture concentrations of Nebraska creamery butter were determined at monthly intervals for 25 months. Samples were obtained from 14 creameries located throughout the state. Their vitamin-A and carotene determinations were made with the aid of a spectrophotometer, and their fat and moisture analyses were determined by the A.O.A.C. methods. From a comparison of these data with the results of investigations in other states it was concluded that Nebraska butter was at least equal in vitamin-A value to average United States butter.
