Abstract:

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.

Key words: pulsed electric fields (PEF), casein, functional property, reversion
