④ Preparation of carotenoprotein complexes from crustacean waste
1. Carotenoprotein complexes from lobster shells using semipurified extract from the Pyloric
caecum and intestines of Atlantic cod
2. The cod enzyme extract recovered relatively lower yield of the products (about 14-46%
less) than bovine trypsin
⑤ Supplementation of squid and herring fermentation with cod trypsin
1. Greenland cod trypsin was used to ferment herring and squid
2. The fermentation was more rapid at lower temperature than bovine enzymes
3. The reaction by the cod enzyme slowed down much more quickly than bovine enzymes
⑥ Prevention of copper-induced off flavors in raw milk
1. Raw milk samples were dosed with cu+2 , then treated with either Greenland cod or bovine
trypsin, to prevent off-flavor development
2. Both enzymes was effective
3. Only the cod enzyme was inactivated after heating at 70℃ for 45 min
4. The cod enzyme can be inactivated by mild treatments to prevent continued proteolysis
⑦ Preparation of shrimp flavor extract with turbot protease
1. An ammonium sulfate protease extract from turbot pancreas and intestines
2. The turbot extract was used to supplement the fermentation of shrimp heads
