Background and Objectives: Virgin olive oil is a vastly consumed product, with widespread appreciation for its good nutritional and health properties. However, oxidation can reduce its quality. The aim of this study was to investigate how the essential oil of Zataria multiflora (Shirazi thyme) can contribute to the prevention of virgin olive oil oxidation in comparison with the actions of &alph...

methanolic extracts of five native species of salvia from the labiatae family were evaluated for antioxidant activity in low-erucic acid rapeseed oil using the schaal oven test at 60°c, with deterioration monitored by determination of peroxide value, conjugated diene content and p-anisidine value. the activity of the salvia extracts was compared with that of tbhq, ascorbyl palmitate, and extrac...

lipid oxidation has adverse effect on food deterioration and human health. the antioxidant activity of fennel seed extracts (fse) was evaluated by synthetic antioxidant. its oxidative stability was compared in olive oils in concentrations of bha (75 ppm), bht(75 ppm) and  1:1 bha to bht ratio. peroxide (pv), p-anisidine (av) and totox values were evaluated to assess the extent of oil deteriorat...

Commercially available fish oil supplements (FOS) are rich in n-3 polyunsaturated fatty acids (n-3 PUFAs) and have been prescribed as complementary therapy to reduce symptoms many inflammatory skin diseases. The objective of this study was assess the PUFAs content, oxidative stability investigate inhibitory effects on immortalized human keratinocytes (HaCaT) cell growth FOS commercialized Brazi...

A 2,4-diarylquinoline derivative, 2-(4-chlorophenyl)-4-(3,4-dimethoxyphenyl)-6-methoxy-3-methylquinoline, was synthesized in a conventional two-step procedure from p-anisidine, p-chlorobenzaldehyde and methyl isoeugenol as available starting reagents through sequence of BF3·OEt2-catalyzed Povarov cycloaddition reaction/oxidative dehydrogenation aromatization processes under microwave irradiatio...

The aim of this study was to determine correlations between the concentration thiamine hydrochloride or pyrophosphate and antioxidant activity epigallocatechin gallate (EGCG) caffeine, as well stability. conducted in model systems. Oxidation degree indices soybean oil (peroxide value anisidine LAN) concentrations total were determined. To compare dynamics changes content during storage, half-li...

The preparation of flavored vegetable oils using spice and herb plants is considered to be an indispensable opportunity for the application these plants. In present exploration, sunflower oil (SFO) samples by Mentha spicata L. (spearmint) were prepared maceration method (MM) ultrasound-assisted (UM). antioxidant effects, sensory evaluation oxidative stability during accelerated storage; physico...
