METHOD FOR MANUFACTURING THE PROTEIN-RICH FEED FROM ANIMAL BY-PRODUCTS TO BREED LIVESTOCK AND FISH

摘要

PURPOSE: Provided is a method for manufacturing a high protein feedstuff for fishes and animals by decomposing waste matters of animals with an alkaline solution and extracting decomposed protein with a acid solution. Therefore, manufacturing time is reduced, the generation of wastewater is inhibited maximumly to prevent environmental pollution, and manufacturing cost is reduced. CONSTITUTION: A method for manufacturing a high protein feedstuff comprises the steps of: collecting waste matters of animals and dipping them in NaOH solution of pH 10; heating the NaOH solution to 50-80 deg.C and holding it for 10-20 minutes to decompose and liquify proteins contained in the by-product; solidifying and simultaneously neutralizing the liquified protein solution by adding HCL solution; and collecting the sludge containing solidified protein and drying it to give a high protein feedstuff.
