Protein hydrolysate was prepared from visceral waste proteins of Persian sturgeon (Acipenser persicus), an Iranian major
sturgeon. Hydrolysis was performed at 55 ° C, 205 min, pH 8.5 by 0.1 AU/g protein E/S Alcalase 2.4L. Protein content for
hydrolysate was 65.82%, and lipid content was 0.18%. The highest degree of hydrolysis was observed in conditions of 55°C
after 205 min. (46.13%) (P<0.05). The results showed that the amino acid profiles of the Persian sturgeon viscera hydrolysates were generally higher in essential amino acid profiles compared with the suggested pattern of requirement by FAO/WHO for adult humans and could fulfill this requirement.
