Commercial Pangasius fillets
The chemical analyses of the 75 samples gave an average
nitrogen content of 2.69 g per 100 g, and fat content of 1.23 g per
100 g (Table 4). The commercially prepared samples had a
significantly lower fat content than the fillets prepared from
whole sh by hand because of differences in trimming the
fillets.
In Table 5 a comparison was made between:
the results of the 3 laboratories,
fillets from fish harvested in the wet and dry season,
the fish processed by the Agifish filleting plant, and those
from the other two filleting plants (DL 147 and 355).
All showed significant differences in the nitrogen content.
There also were significant differences in moisture content with
season and origin (between Agifish and DL147). All the results
were combined to give an average figure for each parameter that
was measured.
