The effects of enzyme action and heat pretreatment on oil extraction yield from sunflower kernels were analysed using hexane with Soxhlet, aqueous incubator shaker. Ground raw treated kernels, each without Viscozyme treatment used. Microscopic images the taken to analyse visible cotyledon cell structure kernels. Heat pretreated before both processes produced enhanced yields than control, steam explosion most efficient. In extraction, applying a combination treatments gave maximum extractable in 1 hour; while for highest yield. Remarkable disruption was evident Viscozyme; whereas conventional had similar effects. .
