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.
