Abstract

The invention relates to a making method for lutein extract microcapsule, belonging to the field of food colorant and nutritional supplement, which comprises the following steps: the lutein extract is added in a carbon dioxide super-critical extraction kettle for extraction with the pressure of 30 to 45 MPa and the temperature of 55 to 70 DEG C, and repeated extraction is conducted to obtain the lutein extract; the lutein extract is heated to 50 to 80 DEG C with the mixed emulsifier added for mixing of 20 to 50 minutes; the temperature is decreased to 40 to 50 DEG C, and the first deionized water is added with continuous stirring, then the second deionized water is added with continuous stirring to obtain a mixed liquid A; the Beta-cyclodextrin and maltodextrin are added in the deionized water with continuous stirring to obtain a mixed liquid B; after mixing, the mixed liquid A and the mixed liquid B are added in a colloid mill to be treated for two times so as to obtain a mixed liquid C; and spray drying is conducted to obtain the lutein microcapsule product. The making method for lutein extract microcapsule has the advantages of good stability and water solubility of the product, long shelf life and suitability for scale production.

Description

technical field [0001] The invention discloses a method for preparing lutein extract microcapsules, which belongs to the fields of food colorants and nutritional supplements. Specifically, it is a preparation method that can change the solubility of the lutein extract from oil-soluble to water-dispersible, and expand the application range of the lutein extract. technical background [0002] Lutein, also known as plant "lutein", widely exists in marigold flowers, and lutein extract can be obtained by extracting marigold granules. Studies have shown that lutein can not only be used as a yellow pigment as a pigment, but also as a functional health product to prevent eye blindness caused by age-related macular degeneration, and can also prevent cardiovascular sclerosis and coronary heart disease. The extraction of lutein extract generally uses No. 6 solvent oil for industrial extraction, which is a conventional extraction method for industrial production, but the lutein extract...
