The present invention relates to a method for producing a water-soluble amino acid extract by using clotted pig blood. More specifically, the present invention relates to a method for producing a water-soluble amino acid extract including fourteen kinds of amino acid and active ingredients from clotted pig blood. Clotted pig blood in a clotted thrombin state is produced into water-soluble powder, and the water-soluble powder is treated by carboxylic acid and pyroligneous liquor, so bloody smells of pig blood and fat components which are animal glycerin are removed. To this end, the method comprises: a clotting step of clotting thrombin state pig blood; a step of producing pig blood powder by pulverizing the clotted pig blood to have a particle size of 600 nm to 35 μm; a step of producing a first mixture by mixing the pig blood powder with distilled water and by heating the same at a temperature of 70-80°C; removing a supernatant solution and separating coagulated and precipitated pig blood by cooling the first mixture at room temperature and by precipitating the same; producing a second mixture by mixing the clotted pig blood and edible acetic acid and by heating the same at a temperature of 60-70°C; filtering and removing precipitated fats and extracting a solution including supernatant water-soluble amino acid by cooling the second mixture at room temperature and by precipitating the same; removing bad smells by mixing pyroligneous liquor with the solution including supernatant water-soluble amino acid.;COPYRIGHT KIPO 2016
