  • High-pressure enzymatic hydrolysis of oil
    Leitgeb, Maja ; Knez, Željko
    The hydrolysis of sunflower and soybean oil, catalysed by two enzymes, non-immobilized Candida rugosa and immobilized Candida antarctica lipase, was performed at atmospheric and high pressure. The ... results showed that at atmospheric pressure between 40°C and 60°C initial reaction rates were influenced by the temperature variation, as expected. Due to favorable physico-chemical properties of dense gases as reaction media, hydrolysis of soybean oil was performed in non-conventional solvents: in supercritical CO2 and near-critical propane. IN SC CO2 the activity of non-immobilised Candida rugosa lipase decreased while the reaction rates of hydrolysis catalysed by immobilised Candida antarctica lipase were 1.5-fold higher than at atmospheric pressure. However, the reaction rates for the hydrolysis catalysed by both lipases were much higher in propane than at atmospheric pressure.
