Journal ArticleDOI
A Quantitative Assay for Lycopene That Utilizes Reduced Volumes of Organic Solvents
TL;DR: Comparative analyses for 105 watermelons from 11 cultivars yielded results equivalent to those provided by larger-volume spectrophotometric assay procedures, suggesting that this reduced volume method may be applicable for tomatoes and tomato products.
Journal ArticleDOI
Lycopene content differs among red‐fleshed watermelon cultivars
TL;DR: This study demonstrated the variability of lycopene content in 11 red-fleshed watermelon cultivars grown at one location, representing seedless, open-pollinated and hybrid types, and in commercially shipped hybrid and seedless melons, representing seasonal production periods.
Journal ArticleDOI
Consumption of Watermelon Juice Increases Plasma Concentrations of Lycopene and β-Carotene in Humans
Alison J. Edwards,Bryan T. Vinyard,Eugene R. Wiley,E D Brown,Julie K. Collins,Penelope Perkins-Veazie,Robert A. Baker,Beverly A. Clevidence +7 more
TL;DR: Plasma lycopene concentrations did not differ at wk 3 after W-20, W-40 and T-20 treatments, indicating that lycopenes was bioavailable from both fresh-frozen watermelon juice and canned tomato juice, and that a dose-response effect was not apparent in plasma when the watermelon dose was doubled.
Journal ArticleDOI
Blueberry fruit response to postharvest application of ultraviolet radiation
TL;DR: In this article, postharvest application of UV-C radiation can decrease decay caused by ripe rot in blueberries and may enhance antioxidant levels, but no clear treatment effects were seen in total phenolic content.
Journal ArticleDOI
Watermelon consumption increases plasma arginine concentrations in adults
Julie K. Collins,Guoyao Wu,Penelope Perkins-Veazie,Karen Spears,P. Larry Claypool,Robert A. Baker,Beverly A. Clevidence +6 more
TL;DR: It is demonstrated that plasma concentration of arginine can be increased through intake of citrulline from watermelon, a conditionally essential amino acid for humans.
