| 中文摘要: |
| 研究花椒籽仁分离蛋白起泡力及泡沫稳定性的影响因素。以花椒籽仁为原料制备花椒籽仁分离蛋白，分别测定在不同的pH、NaCl浓度、蔗糖质量分数以及温度条件下10 mg/mL的花椒籽仁分离蛋白的起泡力和泡沫稳定性，并通过单因素试验和正交试验确定各因素对起泡性的影响程度及其最佳条件。结果表明：随着pH、NaCl浓度、蔗糖质量分数和温度的增加，花椒籽仁分离蛋白的起泡力和泡沫稳定性均呈先上升后下降的趋势；通过正交试验得出花椒籽仁分离蛋白起泡性的最佳工艺条件为溶液pH 13、NaCl浓度0.2 mol/L、温度45?℃、蔗糖质量分数5%，该条件下花椒籽仁分离蛋白的起泡力达到380.58%，泡沫稳定性达到86.43%。 |
| 英文摘要: |
| The factors affecting foaming ability and foam stability of Zanthoxylum bungeanum Maxim. seed kernel protein isolate were studied. With Zanthoxylum bungeanum Maxim. seed kernel as raw material, Zanthoxylum bungeanum Maxim. seed kernel protein isolate was prepared. The foaming ability and foam stability of 10 mg/mL Zanthoxylum bungeanum Maxim. seed kernel protein isolate were determined under different conditions of pH, NaCl concentration, sucrose mass fraction and temperature. The influence degree of various factors on the foaming property and the optimal conditions were determined by single factor experiment and orthogonal experiment. The results showed that the foaming ability and foam stability of Zanthoxylum bungeanum Maxim. seed kernel protein isolate first increased and then decreased with the increasing of pH, NaCl concentration, sucrose mass fraction and temperature. The optimal conditions of foaming property were obtained as follows: solution pH 13, NaCl concentration 0.2 mol/L, temperature 45?℃ and sucrose mass fraction 5%. Under these conditions, the foaming ability and foam stability of Zanthoxylum bungeanum Maxim. seed kernel protein isolate reached 380.58% and 86.43% respectively. |
