High oleic enhancement of palm olein via enzymatic interesterification


High oleic enhancement of palm olein via enzymatic interesterification



Journal of Oleo Science 58(11): 549-555



ISSN/ISBN: 1345-8957

PMID: 19844069

Acidolysis to incorporate oleic acid into refined, bleached and deodorized (RBD) palm olein (IV 56) using various lipases (enzymes) as catalysts to increase the oleic content of the oil was investigated. Immobilised lipases (lipase PLG, Lipozyme TL IM, Lipozyme RM IM and Novozym 435) and non-immobilised lipase (lipase PL) were used in this study to compare the effectiveness of the selected lipases in catalyzing the reaction to produce a high oleic oil. The results showed that the TAG of OLO/OOL content was increased at least 4 fold and OOO content was increased at least 3 fold when a 5% enzyme load was used. Lipase PL showed the greatest increase in tri-unsaturated triacylglycerols (TAGs) content. A pilot scale experiment conducted using TL IM enzyme, followed by recovery of the oil and fractionation allows the production of oils with varying oleic contents. A high oleic content of 56% was achievable.
