twenty spices were employed to preserve the cooked and uncooked fillet of puntius sarana (hamilton) and puntius ticto (hamilton). ic50 values of 2,2’-diphenyl-1-picrylhydrazyl(dpph) based free radical scavenging activity ranged from 0.1123 μg ml-1 in turmeric to 13.035 μg ml-1 in roman coriander. phenol content ranged from 0.365 μg g-1 in onion to 5.67 μg g-1 in clove. the raw and cooked fillet...

Lipid peroxides in tissues were fluorometrically determined using 1,3-diphenyl-2-thiobarbituric acid (DPTBA) as a fluorogenic reagent, and the results were compared with those obtained by the DPTBA-visible method, thiobarbituric acid (TBA)-fluorescence method, or TBA-visible method. The optimum conditions for determining lipid peroxides were analyzed by using brain homogenate. The optimum pH fo...

Relationship among malondialdehyde (MDA), 2-thiobarbituric acid (TBA)-reactive substances (TBA-RS), and tocopherols in the oxidation of rapeseed oil was investigated. MDA was determined by a new HPLC method with chemical derivatization. When the oil was heated at 170 degrees C, TBA-RS and MDA increased. The contents of TBA-RS were approximately 1.6 times higher than those of MDA. Correlation be...

The wide diffusion of 2-thiobarbituric acid (TBA) in the scientific literature is due to the TBA assay, or TBA test, which has been employed in the determination of autoxidative alterations of fats and oils. Two processes occur in autoxidation, generally: the free radical and the photo-oxidation mechanisms. The better studied is the free radical mechanism. The hydroperoxiepidioxides and bicyclo...

background and objectives: tree nuts and their oils contain bioactive materials which have vital roles in improving human’s health. degradation and decreasing the quality of the nuts especially in almond which have high fat is related to the oxidation. the quality of stored almond depends mainly on the kernel moisture and fat , storage temperature, relative humidity, oxygen level, type of packa...

The UV absorption method and the thiobarbituric acid (TBA) test for oxidation of an aqueous suspension of linoleate were compared. The absorption method depends on the formation of hydroperoxides having conjugated double bonds that absorb strongly at 233 nm. The absorption at 233 nm increased markedly during oxidation of linoleate catalyzed by either ascorbic acid or cupric ions. The concentrat...
