Calorimetric and Thermogravimetric Analysis of Agave tequilana Weber Fibers

摘要

Applying extraction processes that involve the use of acid-alkali solutions with or without pressure can enhance the removal of components within Agave fibers as well as the components of more open microfibrils within fiber complexes. At the beginning of the extraction process, important water-soluble components are removed; these include reducing sugars, chlorophylls, and pectins that are widely used in the food industry. TGA coupled with Fourier transform infrared (FTIR) spectroscopy, DSC, and XRD is a useful tool for analyzing any changes that may occur during the dissolution of lignocellulosic materials contained in Agave fibers.
