摘  要:
研究脉冲电场对牛奶酪蛋白功能性质影响的回复性。结果表明:酪蛋白样品经过脉冲电场处理,静置24h后测定的起泡性能和乳化性能在各处理参数下增加的幅度比经脉冲电场处理后立刻测定的有所降低,并且降低的趋势随着脉冲参数的增大而有所减小。

摘  要:
Previous studies have proved that pulsed electric fields (PEF) that has been extensively applied in food preservation may result in the enhancement of functional properties of food. The present study focused on the reversion of effects of PEF treatment on functional properties of casein. Results showed that the increasing degree of emulsifying property and foaming capacity of casein resulted from the PEF treatment declined after standing for 24 h, and this decreasing degree reduced with the increase of the parameters of PEF.
