Bacterial cellulose (BC) has applied as a versatile biomaterial in a wide variety of applications, such as biomedical devices, acoustics, electronics, and paper products. The controlling of the procedure could significantly improve the chemical and structure properties of the BC foams. This study aims to compare the features of BC foam that synthesized from BC disintegrated by a high-speed blender (HSB) and high-pressure homogenizer (HPH). The methods are the synthesis of BC using pineapple skin extract, disintegration process using both HSB and HPH following by freeze-drying process and characterization using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and FTIR. The results show that freeze-drying to the pellicle did not produce a foam structure of BC. SEM morphology indicates that the disintegration process using HPH produces a better porous BC foam compared than HBS process. XRD analysis shows three peaks associated with the structure of BC, which are at 14.47°, 16.85°, and 22.69°. The crystalline structure of BC foam produced from HPH process has higher than BC foam produced from HBS process. FTIR analysis shows that there is a new peak find out in BC foam after the disintegration process. © 2020 Trans Tech Publications Ltd, Switzerland.
