the aim of this study was to develop a diet suitable for obtaining quail eggs enriched with omega-3 fatty acids with minimum disadvantages on egg quality. this 12 weeks study was performed to investigate the effects of fish oil (fo) and savory (satureja khuzestanica) essential oil (eo) supplementation in diets of laying quails at different ages, on their performance, egg quality, fatty acid com...

in the present study, oxidative stability of canola oil extracted with hot press at 85-100ºc was compared with unheated canola oil extracted with cold press at 40-45ºc.the stability of oil was measured every week during a four months storage using free fatty acid, acid value, peroxide value, anisidine value, totex value and rancimat test. the results obtained showed that pretreatment and method...

The present work aimed to evaluate capability of a new molecular structure to stabilize polyethylene against thermal oxidation. Hence, effects of 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one (thymolphthalein) on thermo-oxidative stability of high density polyethylene (HDPE) in both solid and melt states were investigated and compared with those of SONGNOX 1010, a comme...

The present work is aimed to find a new and efficient type of antioxidants for polypropylene. Hence, effects of 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one, generally known as thymolphthalein, on thermo-oxidative stability of polypropylene in solid and melt states were evaluated and compared with those of SONGNOX 1010, an efficient commercially used antioxidant for the po...

background: spindle trees (euonymus japonica thunb.) growing in an industrial complex area containing pollutants is chronically injured thus need to build up their resistance. antioxidant enzymes and cell membrane stability have been widely used to differentiate stress tolerance. materials and methods: leaves of spindle trees from a clean control area (kijang) and an industrial area (onsan) whe...

measuring the rate of changes in total polar compounds (tpc) content and polar fractions, the oxidative stability of canola oil during frying process as affected by bene kernel oil (bko, 0.05 and 0.1%) and tert-butylhydroquinone (tbhq, 100ppm) was investigated. it was observed that the tpc content increased linearly with frying time (r2 > 0.98). the canola oil containing the bko (especially 0.1...

High oxidative stability and catalytic efficiency are required for the alkaline α-amylases to keep the enzymatic performance under the harsh conditions in detergent industries. In this work, we attempted to significantly improve both the oxidative stability and catalytic efficiency of an alkaline α-amylase from Alkalimonas amylolytica by engineering the five oxidation-prone methionine residues ...

The materials used in this study include HDPE (HD100 from M. Holland Company), PP (Polypropylene 3281 from Total Petrochemicals USA, Inc.) and HIPS (IS200 from M. Holland Company). Each polymer was then compounded with SureFlo at two different levels, 5 and 10%. A Q-500 thermogravemetric analyzer (TGA) was used for the study. In each experiment, the sample (typical size ~ 10 mg) was heated from...
