Beef strip loins (IMPS 180; n=15) were sectioned in thirds and sections (n=45) were left untreated (CNT) or injected with either a commercial powder conjugated linoleic acid (CLA) source (Powder) or a commercial oil CLA source (Oil), whose major isomers were 18:2cis-9, trans-11 and 18:2trans-10, cis-12 CLA isomers. Fresh Oil steaks had 3.20 and 3.15, Powder steaks had 4.67 and 4.62, and CNT ste...

n-phthaloyl gaba was administrated daily (50 mg/kg body weight-i.p) to wistar rats for 21 days and circadian rhythms of thiobarbituric acid reactive substances (tbars) and antioxidants such as reduced glutathione (gsh), catalase (cat) and superoxide dismutase (sod) were studied under constant light (ll) conditions. delayed acrophase of tbars and advanced acrophase of antioxidants (gsh, cat and ...

Previous work pointed out the possibility to enhance the nutritional value of meat products using long chain omega-3 PUFA enriched emulsions. Oil-in-water emulsions elaborated with a mixture of algae and linseed oils (15:10) in order to be used as functional ingredient were stabilized with BHA (butylhydroxyanisol) or with a lyophilized water extract of Melissa officinalis L. (Lemon balm). The l...

Cratoxylum formosum Dyer is consumed throughout the year as food and medicine in Thailand. It contains large amounts of chlorogenic acid and quinic acid derivatives. The antioxidative activity of the extract was studied in refined soybean oil coating on rice crackers without any seasoning. They were stored in accelerated oxidation conditions at 40oC, 80% relative humidity (RH) in the dark for 1...

Lipid peroxides were measured in cerebrospinal fluid (CSF) and sera from patients with multiple sclerosis (MS) or other conditions and from control subjects. In serum, visible fluorescence, A240nm, and free and protein-bound thiobarbituric acid (TBA)-reactive substances were significantly greater in MS patients than in control subjects. No such differences were observed in CSF. There was no cor...

The objective of this research was to investigate the effect heating temperature on quality parameters avocado and peanut oils subjected heating. Vegetable were heated at varying temperatures (110, 140, 170, 200 230�C for 30 min) follow alterations. Levels peroxide value, iodine thiobarbituric acid reactive substances, total polar compounds, refractive index, free acidity, fatty acids compositi...

objective(s):this study was designed to evaluate the cardioprotective effect of crocus sativus l. (saffron)aqueous extract and safranal, the major constituent of the essential oil of saffron, on lipid peroxidation, biochemical parameters and histopathological findings in isoproterenol (iso)-induced myocardial infarction in wistar rats. materials and methods:the saffron extract (20, 40, 80 and 1...

This study investigated the effects of mustard seed extracts on physicochemical and storage characteristics dry-aged pork loin ham during aging period. In experiment 1, antioxidant activity was assessed for extracted with varying ethanol concentrations results showed high at 25%, 50%, 75% concentrations. 2, treated obtained using different concentrations: not (control), 25% (MS25), 50% (MS50), ...

the intake of antioxidants intake has been reported to be inversely associated with the incidence of coronary artery disease. to clarify the possible role of lipophilic antioxidants in prevention of atherosclerosis, we investigated the effects of lycopene on the susceptibility of low-density lipoprotein (ldl) to oxidative modification. in this study, “lycopene” was added to plasma and incubated...
