making intramolecular partial sulfydryl exposing and then
free sulfydryl changed on the surface of protein. But DSC
results showed little change on EWP attributing to the
thermal denaturation was unrelated to their free sulfydryl
groups contents. Color measurement experiment results
demonstrated EWP in optimum conditions revealed insignificant
brown stain. Scanning electron micrograph results
proved that the morphology of spray drying was best.
Swelling capacity could perform good quality of EWP.
When EWP was applied as a food ingredient, the acceptability
of modification methods, as well as the toxic
reagents that remained in eggs food should be considered
and avoided [25]. In present study, spray drying has been a
potential excellent alternative choose in egg manufacture
for its no or very little toxicity comparing to other methods
[26]. The approach improved in the present study is
affording a method for optimizing the process of egg
powder method, which may be beneficial for time and
energy costs. Therefore spray -drying egg forcefully has
been an alternative excellent process method.
