The antimicrobial activity and preservative effect of Ceylon spinach (Basella alba L.) seed protein extract on sturgeon fillets stored at 4°C were investigated in this study. results showed that (CSSPE) had inhibitory 33 microorganisms, including 1 fungus 32 bacteria (25 gram-negative 7 gram-positive bacteria). In addition, CSSPE inhibited bacterial growth (total viable counts, Pseudomonas, Aeromonas psychrotrophs), suppressed ATP degradation retained good-quality characteristic 4°C. shelf life 30 mg/mL treated was around days according to the total count, which extended 2 compared with control group. stability also evaluated, excellent under UV irradiation, monovalent metal ions, surfactant protease treatment. could maintain high within range pH 2–8 12–13 its thermal denaturation temperature 70°C. suggested potential be developed as a for aquatic products.
