A Pickering emulsion is an emulsion that is stabilized by solid particles (for example colloidal silica) which adsorb onto the interface between the two phases. This type of emulsion was named after S.U. Pickering, who described the phenomenon in 1907, although the effect was first recognized by Walter Ramsden in 1903. If oil and water are mixed and small oil droplets are formed and dispersed throughout the water, eventually the droplets will coalesce to decrease the amount of energy in the system.

The invention discloses hyaluronic acid-based modified gliadin nanoparticles as well as a preparation method and application thereof. The method for preparing the W2 / O2 / (O1 / W1) type multiple emulsionfrom the nanoparticles comprises the following steps: mixing polyglycerol ricinoleate with corn oil at 65 DEG C to form a first oil phase, mixing a mixed solution of sodium chloride and gelatin with the obtained first oil phase, and performing homogenizing by adopting high-pressure microjet to obtain a W2 / O2 type primary emulsion; mixing a second oil phase with the nanoparticle suspension, and performing high-shear treatment to obtain an O1 / W1 type Pickering emulsion; and mixing the W2 / O2 type primary emulsion with the O1 / W1 type Pickering emulsion by adopting a high-pressure homogenization technology, so as to prepare the W2 / O2 / (O1 / W1) type multiple emulsion. The preparation method of the multiple emulsion is simple, mild in reaction condition and suitable for industrial production, and can be applied to the fields of foods, medicines, cosmetics and the like.

The invention discloses a natural antibacterial eugenol microcapsule and a preparation method thereof. A shell material of the natural antibacterial eugenol microcapsule is a composite shell material consisting of polyurethane and alkali lignin, a core material of the natural antibacterial eugenol microcapsule is eugenol, and the eugenol-encapsulated microcapsule is prepared through a Pickering emulsion method and interfacial polymerization. The shell material is an isocyanate-based polymer raw material which is wide in source, low in cost and easy to obtain, and the core material eugenol is a natural volatile oily substance and has broad-spectrum and high-efficiency antibacterial performance. The microcapsule prepared by the invention is micron-sized, has higher sphericity and has higher eugenol encapsulation efficiency. The natural antibacterial eugenol microcapsule disclosed by the invention has a potential long-acting antibacterial effect through slow release of eugenol. Microencapsulation of eugenol changes eugenol into a solid powder structure from a liquid state, and the eugenol microcapsule has wide application potential in application of antibacterial materials and packaging materials.
