Enzyme Pretreatment To Enhance Oil Extractability In Canola

Abstract

The common aim of all extraction processes is to obtain as high a yield of pure oil as possible and to produce an optimal nutritive value meal (Anjou 1972; Beach 1983). The most commonly used process in Canada involves prepressing of flaked and cooked seeds followed by solvent extraction of oil from the presscake. The energy requirement of this process is high (Ward 1984). The quality of oil recovered by solvent extraction is lower than that of pressed oil (Franzke et al. 1972; Diosady et al. 1983b; Usuki et al. 1984; Pokorny et al. 1987). Meal quality is reduced by high-temperature treatments required to remove hexane.
