Problems solved by technology

However, the preparation of zein-polysaccharide composite particles by anti-solvent precipitation requires the injection or dropwise addition of zein ethanol aqueous solution to the polysaccharide aqueous solution, the process parameters are difficult to control, and the concentration process is time-consuming and energy-consuming.
At present, the research on zein and polysaccharides mainly focuses on hydrophilic polysaccharides, and the research on the interaction with amphipathic polysaccharides is still blank.

Abstract

The present invention discloses a preparation method and an application of a zein-polysaccharide composite particle, and belongs to the technical fields of new materials and functional foods. A zein ethanol aqueous solution and a propylene glycol alginate ethanol aqueous solution are mixed in an equal volume under stirring to obtain a mixed solution, decompression rotary evaporation and centrifugation are conducted to obtain a zein-polysaccharide composite particle dispersion solution, and after drying, the zein-polysaccharide composite particle is prepared. The preparation method is simple and easy to control. The obtained zein-polysaccharide composite particle is used as a solid emulsifier for preparing a Pickering emulsion and the prepared Pickering emulsion had relatively good thermalstability and storage stability.

Description

technical field [0001] The invention belongs to the technical field of new materials and functional foods, and in particular relates to a preparation method and application of gliadin-polysaccharide composite particles. Background technique [0002] Traditional emulsions usually use small molecule surfactants or high molecular polymers as emulsifiers to reduce the interfacial tension of two immiscible liquids, thereby forming a uniform system, which is widely used in food, medicine, petrochemical and other fields. Pickering (Pickering) emulsion is an emulsion system stabilized by solid particles instead of surfactants. Compared with traditional emulsions, Pickering emulsions have the following advantages: it can avoid or reduce the use of surfactants and reduce costs; it has low toxicity and high safety and reduces the harm to human body and environment; the adhesion of solid particles on the oil-water interface The attachment is irreversible, has strong stability, is not e...
