Waste valorization of Rana chensinensis ovum protein isolates versus commercially available proteins isolates from physicochemical, structural, and functional properties to stabilizing Pickering emulsions
This study demonstrated the commercialization potential of Rana chensinensis ovum protein isolates (RCOPI) by comparing it with commercially available proteins from physicochemical, structural, and functional properties to stabilizing Pickering emulsions. The size of RCOPI colloids nanoparticles reached 65 nm which is much smaller than the commercially available proteins. Besides, RCOPI exhibited incredible emulsion ability with the emulsion drop around 22 μm diameters and the zeta potential approximately − 50 mV. The emulsions stabilized by RCOPI showed remarkable stability and the Lactalysis index was about 21% after 100 days storage. In the encapsulation test, scanning electron microscopy (SEM) showed the size of the microcapsule ranging from 20 to 50 μm. The encapsulated efficiency of RCOPI stabilized emulsion was as good as the compared proteins, up to 75%. Furthermore, the results of the sensory evaluation showed that RCOPI stabilized emulsions received the highest approval ratings for appearance, taste, flavor and overall acceptability. Graphic
