摘要: 本文研究了高压脉冲电场对液蛋的杀菌效果及其对液蛋功能性质的影响。结果表明,当电场强度为40kV/cm,处理时间为1660μs时,液蛋中接种的大肠杆菌、沙门氏菌、金黄色葡萄球菌细菌数量可分别降低4.9、5.4和3.8个1g值。在此条件下,PEF处理过的液蛋的黏度、色泽、起泡性、泡沫稳定性、乳化能力和乳化稳定性均没有发生明显变化。

Abstract: The lethal effects on spoilage microganisms and impact on the functional properties of pulsed electric fields(PEF) on samples of liquid whole egg(LWE)were evaluated.The results showed that about 4.9,5.4 and 3.8 lgs reductions of E.coli., salmonella and Staphylococcus aureus inoculated in LWE are achieved at 40kV/cm for 1660μs (2μs pulse width,667pps), respectively.No significant changes in viscosity,color,foaming capacity,foaming stability,emulsifying capacity and emulsify- ing stability are observed after PEF treatment.
