Inter-Esterification

IE is a process where the fatty acids move from one triglyceride molecule to another and it does not alter the fatty acids. It is used to deal with the problems of plastic fat products and create oil more suitable for deep frying or making margarine with good taste and low content of saturated fatty acids, etc. Nutritionally, IE contributes in eliminating or reducing trans fatty acids,  providing a higher essential fatty acid activity. Sodium ethoxide or methoxide as a catalyst is applied more widely for processing Interesterification. it has become the alternative fat modification technology to partial hydrogenation. The reactor is very similar to Hydrogenation Autoclave
