Atlantic salmon is becoming an important economical aquatic
food product in China due to its high nutritional value, excellent
colour and taste. Fish and fishery products are perishable foods
and generally spoil faster than other muscle materials. The major
problem associated with seafood and fishery products is their sus-
ceptibility to putrefaction due to contamination by spoilage micro-
organisms. The spoilage of fish is a complex process with
implicated physical, chemical and microbiological mechanisms.
The application of the electron linear accelerator below 5 MeV
has the limitation of not being able to penetrate deeper into the
food products as compared to 10 MeV. The 10 MeV electron linear
accelerator (power >10 kW), however, tends to replace the
60
Co
gamma-rays and low-energy accelerator irradiation in China as it
could provide a higher processing capability than the traditional
ones. Thus, 10 MeV E-beam irradiation is more suitable for large-
scale industrial production. When it comes to the non-heating
food, such as the fresh-to-eat food, or vegetables and fruits, the
heating method may be much more restricted. Compared with
the heat treatment, E-beam irradiation decreases the maximum
specific growth rate of
Bacillus cereus
and prolonged the shelf life
of the fish flesh after the application of a similar inactivation treat
