Continuous glycerolysis in an immobilized enzyme packed reactor for industrial monoacylglycerol production
Lipase catalyzed glycerolysis processing is of industrial interest since it can be carried out at ambient temperatures and atmospheric pressures. Previously, glycerolysis conducted in a column packed with immobilized lipase were highly potential to ensure a high MAG formation in a short time. In spi...
