Comparison of the Functional Components in Netted and Cantaloupe Melons

초록

This study assessed the utility of netted melon ‘Top Earl’s’ and cantaloupe melon ‘Alex’ as functional fruits by analysing their moisturecontent, vitreous sugar, folic acid, citric acid, and beta-carotene levels. High-performance liquid chromatography (HPLC) was used toanalyse the free sugar, folic acid, citric acid, and beta-carotene levels. The moisture content was not significantly different between‘Top Earl’s’ and ‘Alex.’ The glucose, sucrose, and fructose contents were three, two, and one-and-a-half fold higher in ‘Alex’ thanin ‘Top Earl’s.’ Moreover, citric acid was approximately three times higher in ‘Alex’ than that in Top Earl’s.’ However, the folic acidcontent was higher in ‘Top ‘Earl’s’ than ‘Alex,’ and the amount was 124 μg / 100 g FW and 112 μg / 100 g FW respectively. ‘Beta-carotenewas undetectable in ‘Top Earl’s,’ whereas it was 1000 μg / 100 g FW in ‘Alex.’ β-carotene, a substance that is converted in the bodyinto vitamin A and acts as an antioxidant, is an important component in healthy food. These results suggested that the cantaloupe melon‘Alex’ has a higher free sugar content and functional ingredients, such as antioxidants, including citric acid and beta carotene, thanthe netted melon ‘Top Earl’s.’
