A kind of preparation technology of oil antioxidant containing oleuropein |
| abstract |
The invention discloses a preparation process of an oil antioxidant containing oleuropein, and belongs to the field of chemistry. The preparation process of the present invention comprises the following steps: (1) adding compound enzymes to olive leaf powder for enzymolysis, and centrifuging to obtain supernatant I after enzymolysis; wherein, the components of compound enzymes include cellulase, papaya Protease and α-amylase; (2) adding ethanol to supernatant I, and centrifuging to obtain supernatant II; (3) concentrating supernatant II to obtain concentrated solution III; (4) in concentrated solution III β-glucosidase is added for enzymatic hydrolysis, and after enzymatic hydrolysis, the supernatant IV is obtained by centrifugation; (5) ethanol is added to the supernatant IV to obtain a mixed solution; (6) the mixed solution is filtered to obtain a filtrate; Concentrated and dried. The content of oleuropein in the oil and fat antioxidant prepared by the invention can reach 85-92%. |
