Abstract

Bacterial cellulose has many advantages when applied in various fields, such as medic. This research reported the fibrillation process effect on bacterial cellulose using a blender and HPH on bacterial cellulose produced from pineapple skin waste. The produced pellicle after the fermentation process was cleaned and received treatment from a blender and a High-Pressure Homogenization (HPH) machine. After that, the bacterial cellulose was dried using a freeze-drying method. Use scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) to observe bacterial cellulose. The SEM results showed that the HPH treatment created a more homogenous porosity in the bacterial cellulose. The XRD result presented that similar crystal positions were found at 14°, 16°, and 22°. The HPH treatment produced a higher crystallinity value. The FTIR test showed that the fibrillation process did not change the bonds of bacterial cellulose. © 2022 Author(s).
