[Proteolytic activity control in fish silage].
Microbial fish silage was produced from ground low commercial fish species added with 15% mollase and stored at 35 degrees C. Experiment were conducted to evaluate the effect of the addition of a commercial preparation of bromeline (0.20-0.90%) to the fish silage. Liquefaction was evaluated measuring both the product consistency and its non protein nitrogen content. Results indicate that bromeline addition (0.7 or higher), increases dramatically the rate of proteolysis and decreases the time required for liquefaction from 15 days (no enzyme control) to only 12 hours. Therefore, the use of the commercial preparation of bromeline is highly recommended for silage production.
