dc.description.abstract | Viscera of Barramudi are low quality raw materials or waste, which might environmental and health problems if it’s not utilized. Barramudi viscera have high protein value (31.20%±0.33 bk) and fat (61.44%±1.22 bk). The fat content effects the process hydrolysis, so it requires process of disposal fat (deffating). Process deffating can reduce fat content from 61.44%±1.22 (bk) into 58.71%±0.65 (bk). Hydrolysis barramudi viscera using enzyme papain with activity 30 usp/mL. Optimal concentration of papain used for hydrolisis of barramudi viscera protein is 0.15% with hydrolisis time for 4 hours, temperature 55°C and pH 8. Characteristic products hydrolysates barramudi viscera (Lates calcarifer) has the water content (10.82%±0.84); ash content (7.30%±0.03); protein content (62.85%±0.72); fat content (0.84%±0.28); and carbohydrate (18.19%±1.32); protein digestibility (87.03%). Hydrolysates protein viscera barramundi has 15 content of amino acid, the highest and lowest amino acid, respectively, glutamic acid (10.75%) and histidine (1.38%). Hidrolisat protein can be applied as a source of protein in fish feed. | en |
