Extraction and deacidification are important stages for wheat germ oil (WGO) production. Crude WGO was extracted using subcritical butane extraction (SBE) and compared with traditional solvent extraction (SE) and supercritical carbon dioxide extraction (SCE) based on the yield, chemical index and fatty acid profile. Furthermore, the effects of the molecular distillation temperature on the quali...

The effect of specific oil surface (SOS) during pan frying of rapeseed oil on its thermal stability and antioxidant capacity (AC) was evaluated. Rapeseed oils with different oil layer heights (OLH = 0.5, 1.0, 1.5, 2.0, and 2.5 cm) were heated on an electric frying pan coated with Teflon at 180 ± 10 °C until a selected end point of 25 % total polar compounds (TPC) was reached. The changes of che...

Abstract Sea buckthorn ( Hippophae rhamnoides ) with high antioxidant capacity is distributed all over the world, but has never been used as a natural in oils to replace synthetic antioxidants. Therefore, this study was performed investigate effectiveness of sea extract comparison common rosemary and on retarding lipid oxidation. First extracts were characterised, it found that had higher polyp...

Refined rice bran oil (RBO) was blended with PUFA rich Soybean oil (SBO), MUFA rich Mustard oil (MO) and SFA rich Palm Olein oil (POO) to make a blend that had sufficient amount of Omega-3 fatty acid by mixing two or more oils in the ratio of 60:40 and 60:20:20 respectively. RBO and its blends were subjected to deep fat frying of potato chips at 180±10C for 24h. Oil samples were withdrawn after...

In this work, Phosphotungstic Acid modified Carbon Paste Electrode (PWA-CPE) is used as a substrate for electro-polymerization of o-Anisidine (OA). Also, Triton X-100 (TX-100) surfactant is used as an additive for electrochemical polymerization of OA onto the PWA-CPE, which is investigated as a novel matrix for dispersion of nickel species. The prepared electrodes are characterized by...

in recent years the use of toxic and carcinogenic synthetic antioxidants are recommended to get limited. therefore, the use of natural resource materials as an alternative substitution for synthetic compounds is indispensable. throughout the present study, antioxidation properties of fennel essential oil, at different concentrations containing 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8 mg/ml in ...

In our study, we characterized the antioxidant activity and oxidative stability of cold-pressed macadamia, avocado, sesame, safflower, pumpkin, rose hip, Linola, flaxseed, walnut, hempseed, poppy, and milk thistle oils. The radical scavenging activity of the non-fractionated fresh oil, as well as the lipophilic and hydrophilic fractions of the oil was determined using a 1,1-diphenyl-2-picrylhyd...

Nadeem M., Abdullah M., Hussain I., Inayat S., Javid A., Zahoor Y. (2013): Antioxidant potential of Moringa oleifera leaf extract for the stabilisation of butter at refrigeration temperature. Czech J. Food Sci., 31: 332–339. The antioxidant potential of a leaf extract of Moringa oleifera Lam. (Moringaceae) – LEMO was studied for the stabilisation of butter at refrigeration temperature. LEMO was...

This study was performed to investigate the effectiveness of grape seed extract (GSE) compared to butylated hydroxytoluene (BHT) on retarding lipid oxidation of sunflower oil subjected to convection and microwave heating up to 240 min under simulated frying conditions. The progress of lipid oxidation was assessed in terms of peroxide value (PV), p-anisidine value (p-AV), conjugated dienes and t...
