摘要

Several studies suggest that beta-cryptoxanthin has a greater plasma response from its common food sources than other carotenoids such as beta-carotene and lycopene. The hypothesis of this study is that changes in plasma beta-cryptoxanthin concentrations will be greater than changes in plasma beta-carotene or lycopene concentrations even if these carotenoids are fed in a similar food matrix, such as citrus fruit. We tested this hypothesis by measuring changes in plasma concentrations of beta-cryptoxanthin, lycopene, and beta-carotene after feeding measured amounts of canned tangerines and pink grapefruit to healthy nonsmoking adult humans. Volunteers served as their own controls and received both citrus fruit treatments randomly. In the first study, 8 subjects ate single meals of 234304 g of tangerines or 60-540 g of pink grapefruit. The second study compared changes in plasma carotenoid concentration caused by feeding 234 g of tangerines or 540 g of pink grapefruit to 11 subjects. Blood was collected 5 times within 24 hours after each citrus meal. Carotenoid concentrations were analyzed by reversed-phase high-performance liquid chromatography. Plasma beta-cryptoxanthin concentrations increased within 5 hours and then stabilized, remaining high throughout the 24 hours measured. Plasma concentrations of lycopene and beta-carotene did not change. These results show that beta-cryptoxanthin concentrations increased after a citrus fruit meal, but lycopene and beta-carotene concentrations did not change after a similar citrus fruit meal. These results support our hypothesis that changes in plasma beta-cryptoxanthin are greater than changes in plasma lycopene or beta-carotene, even when these carotenoids are fed in a similar food matrix.
