Effect of Enzyme Extract on Rapeseed Microstructure and Oil Recovery

The effect of enzymatic pre-treatment on microstructural changes in rapeseed was studied using a scanning electron microscope (SEM). The microstructural changes at various reaction times correlate with the increase in oil recovery by solvent extraction. The study validated the rationale behind the enhanced oil recovery from oilseeds due to enzyme pre-treatment that it is because of the enzyme induced biodegradation of cell walls and the break up of complex lipoprotein and lipopolysaccharide molecules into simple molecules releasing extra oil than otherwise extractable.
