Vitamin A activity of selected fruits

, : Vitamin A activity of selected fruits. Journal of the American Dietetic Association 85(12): 1627-1629

A study assessed the vitamin A activity of 7 types of fruits: honeydew melons, cantaloupe, grapefruit (Florida pink and Texas Ruby Red), oranges, and peaches (Clingstone and Freestone). Time of marketing of a given fruit variety was found to markedly affect its vitamin A activity. The range in vitamin A activity IU/100 g varied from about 2500 (cantaloupe) to about 90 (Florida pink grapefruit). The analytical procedure was based on acetone extraction; column cleanup, and spectrophotometric measurement at 447, 450, and 451 nm for alpha-carotene, beta-carotene, and cryptoxanthin, respectively. The results are compared with USDA Handbook No. 8-9 values.(wz)
