Problems solved by technology

Although the embedding effect of anthocyanin microcapsules prepared by spray drying method is not low, there are disadvantages: 1) Most of them use spray drying method, the particle size of microcapsules is difficult to control, and temperature-sensitive materials are prone to degradation; 2) Most of the prepared forms are solid forms , mainly applied to the development of solid and semi-solid products, less applied to liquid food and high-end food, such as health food such as oral liquid, the scope of application is limited

Abstract

The invention discloses a preparation method of anthocyanin emulsion with high embedding rate. The method comprises the following steps: carrying out esterification modification on small particle sizestarch particles with average particle size of 1 to 5 mum by using octenyl succinic anhydride to obtain modified small particle size starch particles with the substitution degree of 0.028 to 0.100; respectively dissolving an anthocyanin extract and a lipophilic emulsifier into water and oil, mixing and carrying out high-speed shearing to obtain W / O emulsion; then uniformly dispersing the modifiedsmall particle size starch particles into distilled water according to mass fraction of 1 to 8 percent (w / w), mixing a mixture with the W / O emulsion and carrying out high-speed shearing to obtain loaded anthocyanins emulsion. The anthocyanin emulsion prepared by the method disclosed by the invention has high embedding rate, simple technology, low oil content, and capability of being applied to the fields of food and beverage, cosmetic water emulsion and the like.

Description

technical field [0001] The present invention relates to an anthocyanin preparation technology, in particular to an emulsion loaded with anthocyanin as an active ingredient and a preparation method thereof, in particular to the preparation of a micron-sized starch-based W / O / W emulsion with anthocyanin as an active ingredient The method belongs to the technical field of preparation of food, medicine and cosmetics. Background technique [0002] Anthocyanins are a kind of water-soluble natural food coloring, belonging to flavonoids, with a C6-C3-C6 carbon skeleton structure, formed by combining anthocyanidin with various sugars in a natural state, and widely exist In plants, it makes plants appear blue, red, yellow or purple, usually derived from grape skin, blueberry, cranberry, red cabbage, purple sweet potato, black wolfberry, etc. Anthocyanin is not only a water-soluble natural pigment widely present in plants, but also an important bioactive substance. In recent years, a ...
