摘要
研究了碱改性对脱脂豆粉表面疏水性的影响。结果表明:碱改性后的脱脂豆粉表面疏水性明显提高。碱改性最佳条件为:脱脂豆粉浓度7%、pH11·7、温度60℃、作用时间1·8h。改性后,脱脂豆粉中蛋白最大表面疏水性指数为1159·6±20·74。
The hydrophobicity of alkli-modified defatted soybean powder was investigated.Results indicated that defatted soybean powder showed higher hydrophobicity than the former after alkli-modification.And the optimized condition was that：the concentration of defatted soybean powder was 7%,pH was 11.7,temperature was 60℃,and time was 1.8h.And the index of the protein hydrophobicity of alkli-modified defatted soybean powder was 1159.6±20.74.
