摘要： The focus of this investigation is to explore the effect of cold plasma modification on the stabilization of water-in-oil (W/O) emulsions with highland barley (HB) proteins. It was notable that following cold plasma treatment, the interfacial tension of the HB protein was significantly reduced, and its rearrangement rate increased by 43 %. These changes indicate enhanced interfacial activity of the protein, suggesting improved interaction between the HB protein and the liquid interface. The average droplet size of the emulsion decreased to 2.61 ± 0.09 μm in the T4 group (40 min treatment), suggesting a more uniform dispersion of the oil droplets. Concurrently, the absolute value of the Zeta potential (28.12 ± 0.73 mV), the viscosity of the emulsion, and the interfacial protein adsorption rate increased. CLSM images confirm that emulsions stabilized by cold plasma-treated HB proteins exhibit smaller and more uniformly distributed droplets. Further confirming that cold plasma treatment improves the emulsification properties of the HB proteins, resulting in more stable emulsions overall. These findings underscore the notion that cold plasma modification represents a promising approach to enhance emulsion stability and possesses considerable potential to augment the functionality of HB protein in a range of applications.
