EKSTRAK RUMPUT LAUT (Kappaphycus alvarezii) SEBAGAI CROSS LINKING AGENT PADA PEMBENTUKAN EDIBLE FILM GELATIN KULIT IKAN NILA HITAM (Oreochromis mossambicus)

The potential applications of gelatine from O.mossambicus skin as a component for edible films was recently observed. The observation leads to the modifications to improve the mechanical properties and inhibition properties of the edible film. One of modification was the addition of cross linking agent. Seaweed extract (K.alvarezii) containing phenol compounds, oxidised phenolic compounds will be converted into quinone, quinone is expected to act as a cross linking agent. The purpose of this study was to determine the characteristics of edible film from O.mossambicus skin gelatine by treatment with the addition of oxidized K.alvarezii extract concentratio
