| titleOfInvention | A kind of preparation method of cryptoxanthin |
| abstract | The invention relates to the technical field of carotenoid preparation, in particular to a method for preparing cryptoxanthin; the marigold flower slurry is diluted and then adjusted to pH value, hydrolyzed by adding hydrolase, lipase and alkaline protease, and subjected to ultrasonic pulverization and filtration. Then, the filter residue is extracted and merged, the material is concentrated, the pH value is adjusted again, and heated to reflux to obtain the product dehydrated lutein, the product dehydrated lutein is isomerized, and the pH value is adjusted, gas is introduced, centrifugation, static In the present invention, the lutein in marigold is extracted by the method of biological enzymolysis, and then the ester is hydrolyzed and saponified by the method of lipase hydrolysis, and the experimental conditions are milder, The product is safe, reduces environmental pollution, reduces the use of organic solvents, and adopts the method of pressurized hydrogenation to obtain cryptoxanthin. |
