The present invention discloses a method for preparing a non-fishy and highly dispersible
egg white powder, belonging to the technical field of
food processing. Starting from the optimization of
egg white components, the present invention combines
antioxidant factor intervention, component optimization (removing reducing sugars, adsorbing with
ion exchange resin and removing
protein components unfavorable to
flavor by
microwave-induced pre-denaturation),
drying condition control, and subsequent
ozone deodorization in multiple
processing steps to combinatorially regulate the
flavor of the
egg white powder, ultimately achieving the preparation of non-fishy egg
white powder and ensuring that
flavor deterioration does not occur during storage, freight and other flow links. The present invention solves two major problems that need to be urgently solved for egg
white powder as a high-quality nutritional
raw material, one is the removal of fishy smell from egg
white powder, and the other is the improvement of the dispersibility of egg white
powder. The concentration and
granulation steps have a significant effect on improving the dispersibility of egg white powder, and are of great significance for promoting the high-value utilization of egg white powder and exploring high-quality healthy
protein raw materials.
