Effects of microwave heating on the antioxidant activities of tomato (Solanum lycopersicum). The aim of this study is to estimate phytochemical constituents and antioxidant activities of tomato slices treated by microwave heating. Quantitative analyses of phenols, flavonoids, lycopene, followed by the evaluation of the antioxidant activity by DPPH (2,2-diphenyl-1-pi- crylhydrazyl) and ion chelating methods, were conducted on ethanolic extracts.

Addition of PPE before inoculation with the starter resulted in stirred yoghurt of higher antioxidant activities than that with PPE added after inoculation with the starter. Also, increasing the percentage of the added PPE increased significantly the antioxidant activities of stir- red yoghurt up to 25% and further increase in the percentage of added PPE led no significant effect.. Addition of PPE had no significant effects on the sensory attributes (appearance, body &.

SCREENING ON ANTIOXIDANT ACTIVITY OF VEGETABLE AND FRUIT BY-PRODUCTS. In this study, we collected and prepared ethanol extracts from 30 vegetable and fruit by-products.. The extracts were screened on antioxidant activities using three methods including determination of total phenolic content (TPC), DPPH free radical scavenging assay (DPPH assay), and ferric reducing/antioxidant power (FRAP) assay. The extracts prepared ginger skin (TN-17) and coffee sediment (TN-16) showed strong activity.

ABTS, DPPH, superoxide radical scavenging activities of melinjo seedlings after 0 to 40 days PEG application. Hydrogen peroxide is the most stable ROS that reactively oxidized other molecules (Michelet et al., 2013). On the other hand, H 2 O 2 plays a role as a signaling component that can induce plant responses to the environmental (Sharma et al., 2012). Hydrogen peroxide is one of the precursors in forming a plant defense system by increasing the antioxidant activities (Mittler, 2002)..
