Effect of dynamic high-pressure treatment on the interfacial and foaming properties of soy protein isolate-hydroxypropylmethylcelluloses systems

The objective of the work was to study the effect of dynamic high-pressure homogenization (HPH) on the interfacial and foaming properties of soy protein isolate (SP) and surface-active polysaccharides (E4M and E15) with different molecular weight.SP was dispersed with water (2% w/v) together with th...
