Lipase catalyse glycerolysis for kinetic resolution of racemates
Bioprocess and Biosystems Engineering, 2007Candida antarctica lipase B catalyzed kinetic resolution of representative secondary alcohols, esters, and amine was successfully performed using triacetin or glycerol as solvents and acyl donor/acceptor. High conversions and enantioselectivities were achieved and the product was easily separated by simple extraction with diethyl ether.

Glycerolysis structured oils as natural fat replacements
Current Opinion in Food Science, 2022Lipase-catalyzed glycerolysis can effectively structure a variety of plant-based oils into solid fats without altering fatty acid compositions. The physical properties of glycerolysis-structured systems changed with oil fatty acid composition, producing solid fat content (SFC)-temperature profiles suitable for different applications.

Production of MAG via enzymatic glycerolysis
AIP Conference Proceedings, 2015Enzymatic glycerolysis of a medium chain methyl ester, methyl laurate was performed using lipase Candida antarctica (Novozyme 435) for 6 hours at 55°C. The percentage of components mixture of product were determined by using gas chromatography technique.

Low-temperature glycerolysis of avocado oil
AIP Conference Proceedings, 2018Glycerolysis can be a useful technique for production of mono- and diacylglycerols from triacylglycerols present in avocado oil. In the present work, the effect of catalyst and co-solvent concentration on low-temperature glycerolysis of avocado oil was investigated at 40oC of reaction temperature.

Glycerolysis of linseed oil: A compositional study
Journal of the American Oil Chemists' Society, 1969AbstractSodium hydroxide catalyzed glycerolysis of linseed oil is greatly enhanced by increase in temperature but only moderately by increase in catalyst concentration. That the active catalyst under these conditions is the glyceroxide ion and not the hydroxide ion was confirmed by performing the reaction with freshly prepared sodium glyceroxide.

Enzymatic glycerolysis for the conversion of plant oils into animal fat mimetics
Food Research International, 2023Substituting animal-based fats with plant-based fats of similar stability and functionality has always posed a significant challenge for the food industry. Enzymatic glycerolysis products are systems formed by converting native triacylglycerols in liquid oils into monoacylglycerols and diacylglycerols, mainly studied in the last few years for their ...

Solvent‐free enzymatic glycerolysis of marine oils
Journal of the American Oil Chemists' Society, 1995AbstractMarine triglyceride oils (cod liver oil and oils from blubber of harp seal and minke whale) were reacted with glycerol using lipase as a catalyst at low temperature. A solvent‐free batch system with magnetic stirring was used. Solidification of the reaction mixture occurred, and a mixture of mono‐, di‐, and triglycerides was obtained in all ...

Enzymatic glycerolysis of a triglyceride in aqueous and nonaqueous microemulsions
Journal of the American Oil Chemists' Society, 1989AbstractEnzymatic solvolysis of a model triglyceride, palm oil, was performed in microemulsions containing isooctane, sodiumbis(2‐ethylhexyl)sulfosuccinate (AOT), palm oil and a combination of water and glycerol as the polar component. Using a 1,3‐specific lipase both hydrolysis, leading to the formation of fatty acid and one mole of monoglyceride, and

High‐yield enzymatic glycerolysis of fats and oils
Journal of the American Oil Chemists' Society, 1991Several triglyceride fats and oils were reacted with glycerol using lipase as catalyst. A batch system with magnetic stirring was used without the addition of any solvents or emulsifiers. In all cases a mixture of mono‐, di‐ and triglycerides was obtained.

Glycerolysis of marine oils and the preparation of acetylated monoglycerides
Journal of the American Oil Chemists' Society, 1960ConclusionsThe glycerolysis reaction was applied to menhaden, tuna, herring, sardine, and salmon‐egg oils. Optimum reaction time for the preparation of α‐monoglycerides was found to vary, reproducibly, from 45 to 60 min., depending on the particular kind of marine oil employed.
