AbstractThis research illustrates the extraction of cellulose from banana peel due to the removal of fat, protein, and pigments from banana peel cellulose (BPC). The optimum extraction and bleaching conditions included using 90% ethanol for 16 h for fat removal, followed by sodium hydroxide pH 11.6 for 24 h for elimination of protein, and soaking in 15% hydrogen peroxide for 3 h for bleaching. The obtained BPC was washed and dried at 60 o C for 10 h. The chemical, physical, and microbiological properties and the cellulose structure as well as the functional properties of the BPC were studied. The BPC contained some impurities and had a lower L* value (84.66) compared with commercial cellulose (CC, 98.61). It also had higher moisture, fat, protein, and ash content as well as water activity but was lower in fiber and cellulose contents than those of the CC. The BPC microstructure was glacial and of various sizes. The bulk, packed, and hydrated densities, and the water retention capacity of the BPC were 0.646 g/ml, 0.923 g/ml, 2.5 g/ml, and 2.91 g water/g dried basis, respectively. The emulsifying activities and oil retention capacity were 40.70 and 0.08 (g oil/g dried basis), respectively. The nuclear magnetic resonance spectra of the BPC indicated that it contained some impurities.
