In general, there were significant influences of drying on
nutritional and sensory qualities of grass carp fillets. Lack
of negative influence of the drying processes on the amino
acid and fatty acid composition of grass carp fillets is of
great practical importance, although drying resulted in a
significant loss of MUFA content. These results show that
different amino acids and fatty acids undergo different
changes at elevated temperatures. However, microwave
drying could improve the protein quality and prevent lipid
oxidation in fish fillets, as compared with the conventional
hot air drying. The microwave-dried samples showed lower
fat loss, higher protein solubility and lower anisidine values
than hot air-dried samples. This research provides basic
nutritional information on freshwater grass carp, both
raw and dried. The present study also provides a possible
application of microwave drying as an efficient drying process
for fish fillets.
