JIMENEZ-MUNOZ, Edith et al. Physicochemical characterization of four species of agaves with potential in obtaining pulp for paper making. Dyna rev.fac.nac.minas [online]. 2016, vol.83, n.197, pp.232-242. ISSN 0012-7353.

The overall objective of this work was to find a new value to the leaves of agaváceas, waste of agribusiness. Four species of agaves were studied in three states of the Mexican Republic: Agave angustifolia (Oacaxa), Agave tequilana (Jalisco), Agave salmiana and Agave lechuguilla (Hidalgo). After a classification taxonomy, phenology, ecological and ethnobotanical (morphology), various physical analysis (moisture, grinding, screening, grading and leaf characteristics, SEM) and chemical (fat and oils, ash, proteins, TGA and DTGA and FTIR were subjected). The species of A. angustifolia and A. tequilana are those with an optimum size of fiber for papermaking. It also corresponds to the highest percentages of cellulose (44.3% and 36.8%) by DTGA. The proximate analysis, it appears that the two species defined as obtaining better for pulp, significant differences have small content of fat, protein, water solubilizable hot material (AT) and moderately alkaline and/or alcoholic solution.

Palavras-chave : Agave ssp.; proximate analysis; DTGA; FTIR; celulose.
