Using critical fluid carbon dioxide to optimize the enzymatic transesterification of soybean oil and ethyl ferulate to feruloyl soy glycerides

Enzymatic Transesterification of Ethyl Ferulate with Fish Oil and Reaction Optimization by Response Surface Methodology

The enzymatic transesterification of ethyl ferulate (EF) with fish oil from cod liver was investigated with Novozym 435 as catalyst under solvent-free conditions. The purpose of the study is to evaluate the synthesis system for the production of feruloyl fish oil in industry. The modified HPLC method was first set up to characterise the reaction products together with liquid chromatography elec...

Enzymatic Transesterification Coupled to Product Extraction in Supercritical Carbon Dioxide

A mixture of fatty acids ethyl esters (FAEE), rich in short chain fatty acids, was produced and extracted in a combined reaction – extraction system, integrated by the use of supercritical carbon dioxide (scCO2). In this processing unit milk fat was partially converted to FAEE by enzymatic alcoholysis. Simultaneously, the lighter FAEE were extracted from the product mixture by flowing scCO2. Th...

the differential effects of debate and media analysis as relate to enhancing efl learners critical thinking ability and writing performances

critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...

consequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
