Performance of Cellulose Membrane from Bacterial Cellulose in Fermented Coconut Oil Treatment

Cellulose membrane was produced from bacterial cellulose in the mixture liquid medium by Acetobacterxylinum. The different medium was used including 100% coconut juice (A), 100% sugar palm juice (B) (Arengapinnata), and the mixture liquid medium between 50% coconut juice and 50% sugar palm juice (C). This cellulose membrane was applied for fermented coconut oil as a microfiltration process to determine the ability of cellulose membrane. The goal of this study is to investigate characteristic of fermented coconut oil resulted and physical properties of membrane cellulose, such as the degree of crystallinity by x-ray diffraction (XRD), water content and thermal decomposition behaviour with TGA, scanning electron microscopy analysis (SEM). From different types of cellulose membrane, cellulose membrane C (50% coconut water and 50% sugar palm juice) is the best physical properties for XRD, TGA and SEM. For all cellulose membrane which applied in fermented coconut oil it was reported that it can reduce water content and free fatty acid, but not significantly for refractive index. Cellulose membrane C was also obtained as a better cellulose membrane to increase the quality of fermented coconut oil.
