| dc.description.abstract | This research aim is to produce peptone with spoiled by cath fish as a raw materials using microencapsulation technique and maltodeskstin as a coating inngridients.. Microencapsulate of peptone has chemical composition with moisture content 8.95%, ash content 5.26%, protein content 62.79%, fat content 0.44% and carbohydrate content 21.48%. The chemical characteristic peptone by-catch spoiled fish indicate that product has solubility 98.87%, nitrogen total 10.05%, α amino nitrogen 1.22%, AN/TN 12.14%, salt content 8.04% and pH 6.69. Microencapsulate peptone has physical characteristic with dominatic colour yellow to redness. Water activity of microencapsulate spoiled by cath fish peptone at room temperature of storage during 5 hours was lower than peptone spoiled by cath fish without microencapsulation and comercial product of peptone. The amino acid content of microencapusalate spoiled by cath fish peptone consist of 15 amino acid that consist of 9 esensial amino acid and 6 non esensial amino acid. Microorganism growth kurve with optical density (OD). That indicate microencapsulate spoiled by cath fish peptone has bacterial growth kurve more good than comercial product of peptone and peptone spoiled by cath fish without microencapsulation. | en |
