One of the simplest methods for short-term handling and storage of fish is the refrigeration in combination with dip treatments. This study was conducted to determine the effect of pre-storage α-tocopherol acetate dipping treatments on lipid stability of refrigerated rainbow trout fillets. Trout fillets were dipped in α-tocopherol acetate solutions (200 and 500 mg kg-1 flesh) and subsequently s...

When paroxysmal nocturnal hemoglobinuria (PNH) erythrocytes were exposed to H(2)O(2) they lysed excessively and formed greater than normal quantities of lipid peroxides when compared to red cells of normal subjects and patients with most types of hematologic disease. It was also shown that lytic sensitivity to acidified serum was related to the enhanced lytic sensitivity to H(2)O(2). If the lip...

 The a im of th is paper was to study the effects w hey pro t e in c oat i ng on ch e m ic al a nd physic al properties of gut t ed K i l ka dur i ng f roz en stor a ge. Coating of Kilka has done by dipping in whey protein solution with different concentrations of 3, 7, 10 and 13%, for 1h. Then, after being packed in polyethylene dishes, they were covered in cellophane blanket and stored in -18...

Lipid oxidation is one of the important factors affecting quality α-instant rice. In this study, α- instant rice was detected with hydrogen peroxide value (POV), malondialdehyde (MDA) and fatty acid (FAV), colorimeter, electronic nose HS-SPME GC/MS before after storage. As well as, effect catalase treatment on during storage investigated The results showed that content MDA in decreased by 41.4%...

Five alfalfa (Medicago sativa L) cultivars from different areas of Iran were evaluated for oxidative markers under salinity conditions. Plants were grown in hydroponic condition by Hoagland nutrient solution containing different amounts of NaCl (control, 50 and 100 mM). Relative growth rate, membrane stability, lipid peroxidation, proline, hydrogen peroxide and relative water contents were dete...

Physiological pregnancy is associated with an increase in lipids from the first to the third trimester. This is a highly regulated response to satisfy energy and membrane demands of the developing fetus. Pregnancy disorders, such as pre-eclampsia, are associated with a dysregulation of lipid metabolism manifesting in increased maternal plasma lipid levels. In fetal placental tissue, only scarce...

This study evaluated the ability of fennel extract to improve the quality of refrigerated minced silver carp over a period of 16 days. Minced silver carp were treated with fennel extract (0.5, 1 and 1.5% w/w), and beta-hydroxy toluene (BHT 200 ppm). The control and the treated fish samples were analyzed periodically (every 4 days) by chemical analysis (Peroxide value (PV), thiobarbituric acid (...

We propose a novel approach for assessment of total antioxidant activity by monitoring kinetics of hydrogen peroxide (H(2)O(2)) scavenging after its injection into liquid sample under study. H(2)O(2) is known to be the strongest oxidant, really presented in human body in contrast to the majority of the model oxidative systems used for evaluation of antioxidant activity. In addition, kinetic app...
