| Abstract: |
| Lipid-reduced soybean protein isolate（LRSP）was prepared by defatted soybean meal，then the composite sol of mass fraction 10% was prepared by konjac glucomannan（KGM）and LRSP with different proportions，and the rheological property and gel texture property of KGM-LRSP composite sol were determined and analyzed. The results showed that the KGM-LRSP composite sol was pseudoplastic fluid and its viscosity increased with the dosage of KGM increasing；the storage modulus G′of KGM-LRSP composite sol with different proportions were all larger than the loss modulus G″，which indicated that a three dimensional network was formed between KGM and LRSP，thus good gel properties of KGM-LRSP composite sol were obtained；comparing with gel prepared by single KGM or LRSP，there was good synergistic interaction between KGM and LRSP，and the KGM-LRSP composite sol showed moderate texture property. |
