I need to separate the monoacylglycerol alone from the used/cooked edible oil. I don't want to use any organic solvents for the separation process. Is there any green technology for this?
OACYLGLYCEROL (MAG) constitutes the major type of food emulsifiers used in many food systems and are also important as a basic starting material to prepare several
other derivatives of modified functional properties. MAG can be prepared by two processes; direct esterification of glycerol with fatty acids or glycerolysis of glycerol with oils or fats (indirect esterification). Current MAG manufacture involves continuous glycerolysis of fats and oils using inorganic alkaline catalysts at high temperature
(220-250° C) under nitrogen atmosphere. Glycerol is an alcohol with three hydroxyl groups, which can be produced as a by-product of biodiesel production through transesterification of oil with alcohol. glycerolysis of crude glycerol derived from biodiesel and treatment by any lipase will be most suitable method.
