Summary

The enzyme activity at low temperatures is very important for the evaluation of an accurate shelf life of chilled products. 7 Bacillus, 4 Pseudomonas, and 3 Aeromonas strains of 5 species were tested on their digestion of gelatine and casein at temperatures from -2 to 7°C for a period of 27 days. Proteolytic activity was observed at all tested temperatures. First reactions occurred after 3 days. Even storage at -2°C did not inhibit the activity of proteases completely. For the practical application can be concluded, that during storage of chilled products proteolytic activity can occur, provided that enzyme synthesis had taken place before chilling started.
