The paper study the improvement of function properties(including solution property,emulsification property and foaming property)of Isolated Soya Protein(ISP)after 100-400MPa High-Hydrostatic Pressure(HHP) treatments.It is discussed the improvement rules of ISP by treatment of HHP.The results show that in ambient temperature,the function properties of ISP solution is bettering with the higher treatment pressure and longer treatment time.Differential Scanning Calorimetry(DSC) prove that HHP treatments will in...
