Study on Preparation and Optimization of Amino Acid Chelated Calcium

Abstract:

Hydrolysis of the raw material that is tilapia(fish heads, fish ribs) to obtain complex amino acid solution and fishbone, Acid-hydrolyzed fishboneThe free calcium to obtain free calcium.Final, Complex amino acid chalated calcium was developed by complex amino acid and free calcium.The experiment obtains better conditions of acid hydrolysis bone and better chelating conditions. Calcium leaching result: Acidolysis temperature 50 ℃, Acidolysis time 100 min, The concentration of Hcl 4 mol/L, the quality rate of Hcl and bone meal 12 mL/g. Chelating result: pH 5, Chelating time 60 min, The quality Rate of complex amino acid and calcium 2.5∶1, Chelating temperature 80 ℃.
