FIELD: chemistry. ^ SUBSTANCE: invention refers to the method of random rearrangement (randomisation) of fat-acid radical of some glycerides to end and central positions; to edible triglyceride fat obtained thereof; to margarine based on it; and to the application of the catalyst Lipozyme« TL IM being the combination of the lipase produced by Thermomyces lanuginosa and silicone dioxide in the claimed method. Method of randomisation goes on up to end positions (Re) conversion in the range from 0.3 to 0.95, up to middle positions (Ra) conversion in the range from 0.06 to 0.75 with Ra being more than (0.32Re-0.08) and includes treatment of the fat with high glyceride content with catalyst containing lipase produced by Thermomyces lanuginosa in combination with silicone dioxide. The combination of lipase/silicone dioxide has an activity at least 250 IUN in the beginning of the method. ^ EFFECT: achieving of the significant level of fat-acid radicals rearrangement to middle position and decrease of reaction time. ^ 16 cl, 8 tbl, 3 dwg, 10 ex |
