چکیده
|
An enzymatic acidolysis to produce modified palm olein with high pufa (linoleic acid, c18:2n-6 and α-linolenic acid, c18:3n-3) was carried out. an immobilized lipase, lipozyme tl im was used as the biocatalyst. the optimum reaction conditions were found at oil:fatty acid mole ratio of 1:2, temperature 50 °c, incubation time 24 h, 1% water in hexane and 10% enzyme. under these conditions, modified palm olein shows high iodine value of 123.08 mg i/100 g oil due to increasing linoleic acid (24.46%) and α-linolenic acid (3.74%) content. linoleic and α-linolenic acid ratio of 21:1 in palm olein was improved to 8:1
