Problems solved by technology

[0004] However, calendula yellow pigment is insoluble in water, can not be suspended in water, and is very sensitive to light and oxygen, thus limiting the application of yellow pigment in medicine, food and beverage industry
At present, there is no research on the development of water-soluble yellow pigment. Microencapsulation of yellow pigment can overcome the shortcomings of insolubility and instability.

Abstract

The invention discloses a method for preparing water-soluble marigold yellow pigment microcapsules. The microcapsules are prepared by an ultrasonic cell crushing synchronous emulsification inclusion method, and the preparation method comprises the following three processes of: blending and homogenizing raw materials, performing ultrasonic emulsification inclusion, and drying, microencapsulating and molding. The obtained yellow pigment microcapsules are 100 percent water-soluble, after the microcapsules are compounded into aqueous solution, the emulsion has the mean grain size of about 190nm, the product can be directly applied or prepared into storage liquid with certain concentration to be applied to medicaments, bakery products, frozen foods, drinks, jellies, jam and the like, and the microcapsules have high physical stability and chemical stability in the processing and storage processes, and have good functions of enhancing nutrition and coloring.

Description

technical field [0001] The invention relates to a method for preparing water-soluble calendula yellow pigment microcapsules, in particular to a method for preparing water-soluble calendula yellow pigment microcapsules by ultrasonic cell crushing and synchronous emulsification encapsulation. Background technique [0002] Yellow pigment is a natural pigment present in marigold and other flowers. It belongs to carotenoids and is a natural antioxidant, coloring agent and nutritional supplement with excellent performance. Calendula yellow pigment is excellent bright yellow, its hue is better than that of carotene, it is lemon and pineapple, and its hue is not affected by the pH value of the medium. [0003] Medical research has confirmed that yellow pigment has an important protective effect on the macula in the retina. When it is deficient, it will easily cause macular degeneration and blurred vision, and will cause symptoms such as vision degeneration and myopia. According to ...
