Conjugated Linoleic Acid (CLA), Glycerol (G) and sunflower oil blends with varying concentration were subjected to enzymatic esterification using a 1, 3- specific immobilized lipase. CLA was used as acyl due to its purported health benefits. The transesterified lipids were evaluated for free fatty acids (FFA) and composition of fatty acids by gas chromatography. Lipozyme RM IM is preferred for ...
In this study, oil was extracted from the liver and visceral fat of Patin (Pangasianodon hypophthalmus) and refined. The yield of oil after refining was 49.98%. The major yield loss (34.20%) happened during the degumming procedure. Fatty acids found in the crude and refined oil were C12:0, C14:0, C14:1, C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C18:4, C20:0, C20:1, C20:4, C20:5, and C22:6. The ...
Heavy metal contamination of soil, water and air has caused serious environmental hazard in the biosphere due to rapid industrialization and urbanization. A variety of metal binding ligands such as organic acids and amino acids involve in the heavy metal remediation mechanisms by plants. This paper analyses the possible role of amino acid histidine and organic acids, namely, citric, oxalic and ...
Background: Padina sp. is an algae that has potential as a functional food. This study aimed to explore the chemical and photochemical constituent in the methanolic exract of Padina sp. Methods: Brown algae of Padina sp. from Puntondo coast, Takalar, Indonesia was prepared. The algae characterization was carried out based on the standard procedure of Association of Official Agricultural Chemis...
Background and objectives: High consumption of trans fatty acids is associated with increased risks cardiovascular diseases, insulin resistance, lipid disorders, diabetes, and possibly cancer. Therefore, most developed countries produce food products with trans fatty acid content of 0%-2% to support the consumers. This study sought to determine the amount of fatty acids in meat products and keb...
Changes of the main sugars and organic acids content in Asian pear (Pyrus serotina Rehd.) Cultivars ‘KS’9 and ‘KS’13 grown in Tehran were studied from fruit set to maturity. The main sugars and organic acids content in fruits were determined 1 and 2 months before harvest, at the time of harvest and 1, 2 months after harvest time using High Performance Liquid Chromatography (HPLC). Fruits were s...
Background: Amino acids have different effects on the growth of dermatophytes. Some may encourage growth while others may inhibit it. These effects not only depend on the type of the amino acid but also on the amino acid concentration and type of the dermatophyte. The aim of this study was to investigate the effects of amino acids on the common dermatophytes in Iran.Methods: In this experimenta...
Low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. It was thought that the HPLC is the best method of the determination of organic acids in the apple juice. In this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for ...
Introduction: Cereal straws contain Cellulose, Hemicelluloses and Lignin and are most available renewable biopolymers. White rot fungi is used to convert these wastes into microbial protein. Pleurotus Florida are having the most delignification ability amongst other micro-organisms. We determined the amounts of protein, essential and non essential amino acids of the produced microbial protein f...
Background: Low density lipoprotein (LDL) particles have shown to be heterogeneous structures with distinctive electrical charges. Alteration in the fatty acids content of the LDL particles is known to affect their structural features, electrical charges, and ultimately physiologic properties and, in this way, may play a role in the pathology of coronary artery disease (CAD). On the basis of ev...
