In Mexico, 145,426 tons of banana (Musa paradisiaca) are produced annually,
which 46,939 tons correspond to Tabasco, that occupies the second place in
production in 2017. During the processes production of this crop, large
quantities of residual that have not utility are generated (fruits of low quality,
broken or yellowish leaves, pseudostem, rachis or pinzote, etc.). However, it has
been reported in different studies the management of these organic residual to
make compost, leachates, bioles and to extract cellulose micro-nanofibers, with
the purpose of reducing the environmental impact. The objective of the present
study was the isolation of cellulose nanofibers agro-industrial residues of
banana rachis. The methodology used for the extraction of cellulose included
various chemical treatments. The microfibers were twice subjected to an
alkaline solution of potassium hydroxide (5% wt KOH), interspersed with a saline
solution (1% wt NaClO2 and NaClO) for bleaching, and finally acid hydrolysis with
hydrochloric acid (1% wt HCl). The nanofibers were characterized by Fourier
transform infrared spectroscopy (FTIR), X-ray diffraction and thermogravimetric
analysis (TGA). Using scanning electron microscopy (SEM), diameters of
nanofibers less than 100 nm were found.
