Abstract:
The purpose of this study was to establish optimal conditions for microwave-assisted phosphorylation modification of egg white. Response surface methodology was used to model and optimize the degree of phosphorylation, solubility, foaming ability, and foaming stability of egg white powder. The concentration of sodium tripolyphosphate, microwave power, and microwave time were selected as the main processing conditions in the phosphorylation modification of egg white protein. The following 3 conditions for optimal phosphorylation modification of egg white are the concentration of sodium tripolyphosphate of 33.84 g/L, microwave power of 419.38 W, and microwave time 90 s for maximum functional properties (solubility, foaming ability and foaming stability) and the concentration of sodium tripolyphosphate of 32.97 g/L, microwave power of 429.29 W and microwave time of 90 s for maximum foaming properties (foaming ability and foaming stability), respectively. We consequently succeeded in phosphorylation modification with microwave assistance and confirmed the various desirable properties of optimal phosphorylation modification.

Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
