Description 
Storage in alkali solutions is an emergency method of holding fish when landings exceed plant capacity. After heating and oil separation the aqueous phase is acidified and dried to yield alkali-reduction meal. The maximum concentration of sodium hydroxide that should be used in the storage liquor seems to be slightly above 2%. When 2.25% sodium hydroxide solution was used for storage, there was less destruction and the alkali-reduction protein was nutritionally similar to soybean meal protein.
Nutritional aspects
Nutritional attributes 
The nutritive value of the meal depends on the concentration of sodium hydroxide in the solution.
Potential constraints 
With 3% sodium hydroxide the meal was toxic to poultry and low in nutritive value because of partial destruction of vitamins and essential amino acids.
