Bitter gourd (Momordica charantia L.) has been used since long time as food and medicinal plant. This research study was performed to determine the antioxidant activity of the Bitter gourd chips by DPPH radial-scavenging activity and ABTS assay. Total phenolic content was measured by Folin-Ciocalteu reagent. The different MAP gases concentrations used for the packaging of chips were 100% N2: 0% CO2, 70% N2: 30 % CO2 and 50 % N2: 50 % CO2. The temperatures used for storage were at room temperature, 37οC and 45οC. The best result was shown by 100% N2: 0% CO2 package stored at room temperature. | Anti-radical and microbial analysis of map stored bitter gourd chips short-running title Map storage study of bitter gourd chips
