| 中文摘要: |
| 将大豆分离蛋白溶解在尿素/无机盐Au水溶液中，研究尿素/无机盐Au水溶液体系中尿素的浓度和无机盐Au加入量对大豆分离蛋白的变性和流变特性的影响。结果表明：大豆分离蛋白在尿素/无机盐Au水溶液体系中能够形成稳定且流动性良好的溶液；大豆分离蛋白在尿素/无机盐Au水溶液中结构被破坏，溶解性增加；溶液表观黏度随无机盐Au加入量增加先减小后增加，随尿素浓度的增加明显下降，随温度升高而降低；大豆分离蛋白尿素/无机盐Au水溶液的吸光度随着尿素浓度的增加明显减小，而无机盐Au加入量对大豆分离蛋白尿素/无机盐Au水溶液的吸光度的影响不明显。 |
| 英文摘要: |
| The soybean protein isolate was dissolved in urea/inorganic salt Au aqueous solution, and the effects of urea concentration and inorganic salt Au dosage in urea/inorganic salt Au aqueous solution system on denaturation and rheological properties of soybean protein isolate were studied. The results showed that in urea/inorganic salt Au aqueous solution system， soybean protein isolate could form stable and good fluidity solution and its structure was destroyed, making its solubility increase; with inorganic salt Au dosage increasing, the apparent viscosity of the solution first decreased and then increased, while it reduced significantly with urea concentration increasing and temperature rising; the absorbance of urea/inorganic salt Au aqueous solution of soybean protein isolate declined markedly with urea concentration increasing, while inorganic salt Au dosage had no obvious effect on the absorbance of urea/inorganic salt Au aqueous solution of soybean protein isolate. |
