Increasing consumer knowledge of the link between diet and health has raised the awareness and demand for functional food ingredients. Meat and its derivatives may be considered functional foods to the extent that they contain numerous compounds thought to be functional. This review will attempt to outline the excellent nutritional and dietetic properties of rabbit meat and offer an overview of...
کرچک (ricinus communis l.) یکی از مهمترین گیاهان دارویی مورد استفاده در صنایع داروسازی، آرایشی و بهداشتی بیشتر کشورهای توسعه یافته است. روغن بدست آمده از دانه های این گیاه جزء با ارزش ترین مواد مسهل و ملین در پزشکی می باشد. فاکتورهای اقلیمی بویژه عرض جغرافیایی، ارتفاع محل، درجه حرارت، شدت نور، بارندگی و خصوصیات خاک، تاثیر عمده ای بر کمیت و کیفیت مواد موثره می گذارد. به منظور مطالعه تاثیر اقلیم ...
Microalgae have been receiving worldwide attention as promising feedstock for production of carbon neutral biodiesel. As an alternative fuel, biodiesel is very imperative for the sustainable development of mankind. Biodiesel production process is generally carried out through upstream and downstream processing to generate cellular biomass, extracted oil and finally transesterification reaction....
Lipase-catalyzed synthesis of lipophilic phenolic antioxidants was carried out with a concentrate of n-3 polyunsaturated fatty acids (PUFAs), recovered from oil extracted from salmon ( Salmon salar ) byproduct. Vanillyl alcohol and rutin were selected for the esterification reaction, and obtained esters yields were 60 and 30%, respectively. The antioxidant activities of the esters were compared...
A series of phthalic acid derivatives (P) with a carbon-chain tail was designed and synthesized as single-component gelators. A combination of the single-component gelator P and a non-gelling additive n-alkylamine A through acid-base interaction brought about a series of novel phase-selective two-component gelators PA. The gelation capabilities of P and PA, and the structural, morphological, th...
Petroleum contains many heterocyclic organosulfur compounds refractory to conventional hydrodesulfurization carried out with chemical catalysts. Among these, dibenzothiophene (DBT) and DBTs bearing alkyl substitutions are representative compounds. Two bacterial strains, which have been identified as Paenibacillus strains and which are capable of efficiently cleaving carbon-sulfur (C--S) bonds i...
The triacylglyceride components of cottonseed oil were isolated and positively identified by a combination of high performance liquid chromatography (HPLC) and gas chromatography (GC). Both reversed-phase HPLC and capillary GC were capable of separating the oil into triacylglyceride peaks. These peaks were isolated by HPLC and their component acyl groups were converted to fatty acid methyl este...
Lecitase Ultra® solutions are mainly composed of bimolecular aggregates two open structures the enzyme. The immobilization and fixation these onto support surfaces is here proposed as a novel protocol for stabilization Lecitase. resulting derivatives were much more stable than diluted most them was obtained by covalent aggregate: 300-fold enzyme 75-fold adsorbed hydrophobic supports. aggregate ...
We recently reported on the synthesis of different chain length α,ω-diester monomers from plant oil derived fatty acid esters or fatty alcohols via olefin cross-metathesis with methyl acrylate taking advantage of natures "synthetic pool" of fatty acids with different chain lengths and positions of double bonds. [1,2,3] Similarly, we could show that their cross-metathesis with allyl chloride all...
India is the world’s largest producer of castor oil, producing over 75% total supply. Castor oil unique owing to its exceptional diversity applications. The and derivatives are used in 100 different applications diverse industries such as paints, lubricants, pharmaceuticals, cosmetics, paper, rubber more. possibly plant industry’s most underappreciated asset. This study conducted Salem Namakkal...
