The antioxidative potential of sea grapes (Caulerpa lentillifera, Chlorophyta) can be triggered by light to reach comparable values of pomegranate and other highly nutritious fruits

Abstract The interest in edible sea grapes ( Caulerpa lentillifera ) is increasing due to their potentially beneficial effect on human health. This macroalga, already used for direct and indirect consumption, grown aquacultures Vietnam Philippines. Here, the fronds of were examined antioxidant activity (AOA) at light intensities from 140 300 µmol photons m −2 s −1 compared commercially dehydrated C. renowned highly antioxidative fruits Pomegranates Punica granatum ), Goji Lycium barbarum L. chinense Aronia melanocarpa) berries, using an ABTS + -assay all samples. AOA exposed 14 days increased by about 320% initial value 72.2 ± 5.6 232.2 34.2 Trolox Equivalents (TE) mmol 100 g dry weight (DW) onto level (272.8 23.0 TE DW). application could be as a post-cultivation treatment grape cultures increase quality nutritional product.
