An attempt of synthesis 2-monolaurin from lauric acid through trilaurin as an intermediate compound has been successfully conducted. Trilaurin afforded via esterification reaction and glycerol with yield purity 78 84% respectively. Ethanolysis using Lipozyme TL IM enzyme resulted in the formation a 60 % 97%.

An alternative route to produce biodiesel is based on esterification of free fatty acids present in byproducts obtained from vegetable oil refining, such as palm oil fatty acid distillate (PFAD). PFAD is a byproduct of the production of edible palm oil, which contains 96 wt.% of free fatty acids. The purpose of this work was to study biodiesel synthesis via esterification of PFAD with methanol ...

A few issues to apply Lipozyme TL IM-catalyzed interesterification for bulk fat modification were investigated in a batch reactor system with concerning practical process development. The hydrolyzed products, i.e. free fatty acids and diglycerides, generated from the Lipozyme TL IM-catalyzed interesterification process due to water participation, can be minimized by enzyme pre-treatment. For th...

In the present work, direct enzyme-catalysed esterification of medium chain fatty acids (MCFA) from three different sources (Medium chain triacylglycerols, MCT; saponified MCT and a mixture of free MCFA) was evaluated to obtain structured mono- and diacylglycerols. The esterifications were carried out mixing the different sources of MCFA with glycerol at two weight ratios (1:1 and 4:1, w/w), us...

Abstract Cinnamic acid is a phenolic compound that has the potential to act as natural antioxidant. esterification can be performed by adding alcohol an alkyl group donor. This carried out increase antioxidant capacity of cinnamic acid. Esterification with butanol donor was best condition modify In this study, synthesis butyl cinnamate using enzymatic membrane reactor (EMR) continuously Lipozym...

Phospholipids (PLs) are significantly utilized in different areas of food, pharmaceutical and cosmetic products as emulsifiers, stabilizers and antioxidants. The properties of PLs can be modified with a view to improve its inherent properties like emulsification and oxidative properties as well as tailor made technological and physiological properties. Advancement of biotechnology serves as a v...
