Abstract

The invention relates to a preparation method of strawberry polyphenol microcapsules and belongs to the technical field of microcapsule preparation. According to the preparation method, strawberry polyphenols are used as core materials; mixtures of one kind or more than two kinds of materials from sodium alginate, maltodextrin and arabic gum are used as wall materials; one kind of materials from soft soybean phospholipids, lauryl sodium sulfate and stearin is selected as an emulsifying agent; the stirring and the dispersion are carried out under the specific conditions; and then, the spray drying is carried out, and the strawberry polyphenol microcapsules can be obtained. The strawberry polyphenol microcapsules prepared by the method can prevent the oxidation of the strawberry polyphenols, meanwhile, the effective activity of the strawberry polyphenols is effectively maintained, and the bioavailability in the normal environment is improved. The problems of activity instability and low absorption and utilization rate in the application process of biological activity ingredients are solved to a certain degree, and the storage period of the strawberry polyphenols is greatly prolonged.

Description

technical field [0001] The invention relates to a method for preparing strawberry polyphenol microcapsules, which belongs to the technical field of microcapsule preparation. Background technique [0002] The phenolic hydroxyl groups contained in polyphenol molecules are very active, and are easily affected by high temperature, humidity, light and other environmental conditions, and are prone to polymerization, oxidation, condensation and other reactions to lose their biological activities such as anti-oxidation. Because strawberry polyphenols are powdered and have very fine particle size, they are more likely to absorb moisture and agglomerate in the natural environment. Therefore, the isolated polyphenols are prone to oxidation during storage, transportation and application, which will greatly reduce their use effect. It is very necessary to find a method to avoid autooxidation of polyphenolic compounds, etc., so as to ensure the stability of its activity and expand the app...
