A Modern Dewaxing Technology For Edible Oils Refining

Abstract

The modern dewaxing process using endogenous wax ester hydrolyses (wax desynthetase) activation in optimal reaction conditions provides an efficient, specific and targeted affinity destructuration process orientated towards the wax substrate in order to develop the depparafinage effect. The lipase W/O interfacial activation was studied in the lipolyse and interesterification process but the endogenous O/S dewaesterase activation was until now non-investigated. The isoparaffins structures formation improves the dewaxing yield at 90.7% reported on the miscella crude oil with 270 ppm waxes content with an almost double-cold dewaxed oil stability. The present modern dewaxing technology eliminates the low-efficiency cold/low temperature crystallisation and all the negative effects given by the solvent oil recovery from the kieselgur pomace, cooling agent producing and separation by filtration/centrifugation process.
