Effects of κ-carrageenan on textural and rheological properties of soy protein isolate(SPI) emulsion gels were studied. Influences of different polysaccharides (sulfate polysaccharide:κ-carrageenan, carboxyl polysaccharide: Carboxymethylcellulose, and neutral polysaccharide: guar gum, methylcellulose) on stabilities of SPI stabilized emulsions were systematically studied. Mechanisms of these polysaccharides affecting emulsion stabilities were discussed in this dissertation. Results were indicated as follows...
