Palliatives for enhancing the stability of beer flavor have been evaluated by organoleptic tests, but primarily by use of an accelerated aging technique, followed by estimation of staling substances using thiobarbituric acid (TBA). TBA has also been used to trace the quantities of carbonyl compounds and their precursors through malting and brewing and in beer treated with palliatives and substa...

The aim of this study is to assess the effect polyphenol curcumin on lipid peroxidation (LPO) in homogenate cerebral hemispheres from rats exposed round-the-clock lighting (RCL) and kept high-calorie carbohydrate-lipid diet (HCCLD). experiments were performed 21 white male Wistar weighing 210-250 g, divided into 3 groups 7 animals each. Animals group 1 (control I) a standard vivarium equal alte...

In this study, an anti-oxidant nanoformulation to prevent the oxidation of salmon was developed using rosmarinic acid (RA). Minced samples (MSs) were treated with 8.10-3 g (RAT1) and 16.10-3 (RAT2) RA-loaded nanoparticles for 100 MS acid, separately. The thiobarbituric (TBA) values control (C), RAT1, RAT2 stored at 4 °C found as 2.995, 1.350, 0.994 mg MDA/kg; respectively, after 9 days. While i...

Inhibition of Ehrlich ascites carcinoma respiration by aqueous extracts of oxidized linoleic or linolenic acid (aqueous emulsions UV-irradiated, 90 min) was associated entirely with relatively involatile compounds which were both thiobarbituric acid (TBA)-reactive and peroxidase-reactive. Inhibitory compounds were heat stable and migrated in thin-layer chromatography with aldehydes, "hydroperox...

The effect of aqueous solution of citric acid (CA) on the lipid stability of the European catfish (Silurus glanis) fillets during frozen storage (up to 6 months) was investigated. Rancidity development was measured by several biochemical indices (free fatty acids, peroxides and TBA) and complemented by the measurement of expressible moisture and sensory evaluation (flesh odor, consistency and f...

All the chemicals used in the present study were of analytical grade and were obtained from standard companies. ELISA plates, tissue culture plates (96 /8 well), culture dishes, Serological plates, Roux culture bottles, 0.2μm sterile syringe filters (non-pyrogenic). DMBA (7,12-Dimethylbenzylanhracene), TPA (12-O-tetradecanoylphorbol13-acetate), RPMI 1640 (Rose Well Park Memorial Institute Lab n...

The studies were undertaken on examining the influence of different linoleic/linolenic acid ratios in the diet of pregnant cows on some parameters which are involved in metabolism of prostaglandins in their placentas. Phospholipase A2 (PLA2) which provides arachidonic acid (AA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) the two being involved in neutralization of reactive oxyg...

This study aims to compare low-fat chicken mortadella made with whole muscle (WCM) and mechanically deboned meat (MDCM) that were enriched flaxseed oil thyme oil. Four types manufactured: 100% WCM (T1), MDCM (T2), + 2% 0.15% (T3), (T4). Mortadella samples investigated for proximate composition, thiobarbituric acid (TBA) value, pH, fatty profile, color, sensory evaluation. Proximate composition ...
