| 摘 要： | 为了明确全蛋液均质处理对其功能性质影响规律,对不同压力均质处理后全蛋液蛋白溶解度、起泡性、乳化性、凝胶强度等功能性质及应用全蛋液制作的海绵蛋糕比容的变化进行了研究。结果表明:在5～40 MPa压力内,随着均质压力的升高,全蛋液起泡力、乳化活力和海绵蛋糕比容明显降低,泡沫稳定性和凝胶强度明显提高,乳化稳定性的变化比较复杂,蛋白质溶解度基本保持稳定。在实际生产中需要根据全蛋液应用时所侧重的功能性质选择适宜的均质条件。

| Abstract: | The effect of homogenizing treatment on protein solubility,foaming properties,emulsifying properties and gel strength of liquid whole egg(LWE) and specific volume of sponge cake produced by LWE were investigated.The results showed that foaming stability and gel strength of LWE were improved when the pressure of homogenizing treatment was increased from 5 to 40 MPa.Foaming capacity,emulsifying activity of LWE and specific volume of sponge cake were decreased when the pressure of homogenizing treatment was increased.Effect of homogenizing treatment on emulsifying stability was complicated.Protein solubility of LWE does not change significantly after homogenizing treatment.Proper pressure of homogenizing treatment should be chosen for the needs of different functional properties of LWE in application. |
