The present work has been carried out to ascertain the influence of different processing systems employed in olive process on the chemical composition, quality and stability of three Chemlali olive oils. Among these oils, two were classified as extra-virgin olive oils and the third named repassed olive oil was classified as an ordinary virgin olive oil. The analysis of the effect of the process...

in this study, the oil yield, fatty acid (fa) composition and the physicochemical and quality characteristics of salvia macrosiphon crude seed oil were determined. the main fatty acids ranked in the following order of abundance: α- linolenic acid> linoleic acid> oleic acid. the n3 /n6 fa ratio and polyunsaturated fa/ saturated fa ratio were 1.6 and 7.23, respectively. the fa composition reveale...

The aim of this study was to assess the alterations in plasma, liver, and meat oxidative stability and α-tocopherol content when moderately oxidized sunflower oils were added to feeds and when feeds were supplemented with α-tocopheryl acetate (100 mg/kg) and Zn (200 mg/kg). The effects of cooking the meat and its subsequent refrigeration were also studied. When the content of primary oxidation ...

Metalworking fluids (MWFs) increase productivity and the quality of manufacturing operations by cooling and lubricating during metal forming and cutting processes. Despite their widespread use, they pose significant health and environmental hazards throughout their life cycle. An obvious environmental improvement to MWF technology would be to improve the lifetime of the fluid while utilizing mo...

Choibá (Dipteryx oleifera Benth.) is a promising source of edible oil with high nutritional quality and a significant content of oleic acid (52% 54%). To promote Choibá as source of edible oil is necessary to ensure its stability along the time of production, distribution and storage. Loss of nutritional and organoleptic quality in lipids is mainly due to lipid peroxidation reactions. The aim o...

Ficus pumila leaf and the seed oil of Moringa oleifera contain significant amount of vitamins and vital nutrients which mitigate vunerable diseases. Essentially, the goal is to screen the stability of rutin, a valuable antioxidant and validate the mechanism of its kinetic degradation in Ficus pumila leaf with and without oil extracted from M. Oleifera seeds. Experiments were planned according t...

Phase change materials (PCMs) have been used in various fields including the materials of buildings. In this research, mixed shape-stabilized PCMs (Mixed SSPCMs) were prepared by impregnating coconut oil and n-hexadecane into exfoliated graphite nanoplatelets (xGnP) through a vacuum impregnate method. Coconut oil is fatty acid ester PCM which is relatively economical in comparison to other PCMs...

Oxidation of tocotrienol enriched corn oil was measured for primary oxidative products, lipid hydroperoxides and quantified by peroxide value (PV). Oxidative Stability Index (OSI) was used to determine the induction period (hrs) by indirect measurement of volatile secondary oxidation products, mainly formic acid. Vitamin E stripped corn oil samples were spiked with individual tocotrienols or to...

Despite remarkable strides in science and technology, the strategy for spilled oil collection has remained almost the same since the 1969 Santa Barbara oil spill. The graphene vessel devised here can bring about an important yet basic change in the strategy for spilled oil collection. When it is placed on the oil-covered seawater, the graphene vessel selectively separates the oil, then collects...

Potential food-compatible technologies for novel oil-in-water emulsions include interfacial cross-linking by enzymatic means. The objective of the present research is to elucidate the mechanisms, by which protein interfaces control transfer of low molecular weight compounds. As a first step, the impact of enzymatic cross-linking on mechanical properties of -casein layer was studied. The depende...
