Glycerolysis-structured Lipid Systems
2022Lipase-catalyzed glycerolysis converts native triglycerides into partial glycerides and has been shown to be an effective technique for structuring plant-based oils into solid fats without altering the fatty acid composition. This approach has been successfully used to structure a variety of oils with differing fatty acid compositions.

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.

Glycerolysis of free fatty acids: A review
Renewable and Sustainable Energy Reviews, 2021Abstract Lesser-polluting and carbon-efficient systems are the new standards of energy, globally. Biodiesel is an excellent bioenergy source due to its industrial feasibility and engine adaptability. However, biodiesel resource inventory still lacks feedstock flexibility on a commercial scale and mostly relies on vegetable oils for production.

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.

Glycerolysis of tallow with immobilised lipase
Biotechnology Letters, 1993Lipozyme (immobilised Mucor meihei lipase) was used to catalyse glycerolysis of melted tallow to synthesise monoglycerides. At a reaction temperature of 50 °C, a maximum 35% yield of monoglyceride was obtained. Cooling the reaction below 42°C resulted in monoglyceride crystallisation which improved the yield to up to 50% but further yield increases ...

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 peanut and mustard oils
Journal of the American Oil Chemists' Society, 1955SummaryThe glycerolysis of peanut and mustard oils has been carried out in the presence of catalysts such as lime and litharge. The effect of time and temperature on the rate of glycerolysis has been studied. The monoglyceride contents and hydroxyl values of the washed samples have been determined.

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.

Diacylglycerol‐enriched oil production using chemical glycerolysis
European Journal of Lipid Science and Technology, 2016Diacylglycerol (DAG)‐enriched oils have been drawing increased global attention from researchers and food manufacturers. The production of DAG‐enriched oils have been investigated extensively because of its health benefit. DAG is commonly produced chemically through glycerolysis processes.

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 ...
