Linoleic, oleic, and stearic fatty acids, presented vapor-phase retronasally, were discriminable from blanks and each other, but the same concentrations, oral-cavity-only (OCO), were not discriminable from blanks. It remained possible that higher concentrations might be discriminable OCO. To evaluate this, participants attempted to discriminate undiluted linoleic, oleic, or stearic acids, vapor...

To develop biodegradable packaging that both acts as a moisture barrier and as antimicrobial activity, nisin and stearic acid were incorporated into a hydroxy propyl methyl cellulose (HPMC) based film. Fifteen percent (w/w HPMC) of stearic acid improved film moisture barrier. However, film mechanical resistance and film antimicrobial activity on Listeria monocytogenes and Staphylococcus aureus ...

this study carried out to determine the differences between oil content and fatty acid compositions of 12 exotic and 6 local safflower genotypes. the experiments were arranged in randomized complete blocks design with three replications in research station of ferdowsi university of mashhad. the results of variance analysis showed that the differences of seed yield, oil content and fatty acid co...

For determining the fatty acid characteristics and biodiesel quality of Ethiopian Jatropha provenances, the study was conducted in five regions namely Southern Nation Nationalities Peoples Regional State (SNNPRS), Amhara region, Tigria region, Oromia region and Benishangul Gumuz Regions, where physic nut is found abundantly. For each region, representative sampling sites were selected following...

Supercritical fluid extraction and expansion (SFEE) patented technology combines the advantages of both supercritical fluid extraction (SFE) and rapid expansion of supercritical solution (RESS) with on-line coupling, which makes the nanoparticle formation feasible directly from matrix such as Chinese herbal medicine. Supercritical fluid extraction is a green separation technology, which has bee...

Abstract Green Diesel (diesel-like hydrocarbon) can be produced from biomass resources that contain fatty acids, such as palm fruit, kernel, and soybean, through deoxygenation reaction. In this study, the catalytic activity of cobalt catalyst supported on activated biochar in acid (stearic acid) is investigated. Stearic used a model compound vegetable oil. The obtained results show exhibited hi...

J. Anim. Sci. Vol. 87, E-Suppl. 2/J. Dairy Sci. Vol. 92, E-Suppl. 1 (P ≤ 0.1) P3 activity (1.87 vs. 0.34 arbitrary units for stearic vs. control, respectively). Activity of P2 was not altered (P ≥ 0.05) by any treatments and there was no response to glucocorticoids or unsaturated fatty acids for any of the promoters tested. Stearic acid suppresses the activity of bovine PC promoter 1 but enhanc...

Structured lipids (SLs) containing palmitic, oleic, stearic, and linoleic acids, resembling human milk fat (HMF), were synthesized by enzymatic acidolysis reactions between tripalmitin, hazelnut oil fatty acids, and stearic acid. Commercially immobilized sn-1,3-specific lipase, Lipozyme RM IM, obtained from Rhizomucor miehei was used as the biocatalyst for the enzymatic acidolysis reactions. Th...

Desaturation of [1-r4C]stearic acid, [lJ4C]palmitic acid, and [l-14C]stearoyl-CoA was measured in homogenates of lo-day-old rat brain. Desaturation was maximal with stearoyl-CoA at pH 6.0 to 6.6. With free fatty acids, monoene formation was maximal at pH 7.2 to 7.6; stearic acid was more actively desaturated than palmitic acid. Activity with stearic acid or stearoyl-CoA was linear with protein ...
