چکیده انگلیسی
The aim of this work was the determination of the best experimental conditions for the production of amino acids from bovine serum albumin (BSA) by continuous sub-critical water hydrolysis. The results were compared with conventional acid hydrolysis in HCl. At a residence time of 30Â s and a pressure of 25Â MPa, the highest amount of amino acids was obtained at 583Â K. An increase in residence time to 90Â s led to a shift of the temperature optimum to 543Â K. The highest amino acid yield in sub-critical water was obtained at 563Â K and 65Â s. No significant influence of operating pressure (15-27Â MPa) could be observed at the tested temperature (523Â K) and residence time (30Â s). The addition of carbon dioxide led to an increase in amino acid yield due to the acceleration of acid hydrolyzed catalysis steps. This protein treatment may provide a practical and economical solution for the disposal of protein-rich sources like marine wastes, hairs, and feathers, which are considered as waste so far.
