MORENO QUINTERO, María E; GUTIERREZ BARBUENA, Julio C; GUTIERREZ R, Betzabeth G  y  SANCHEZ PEREZ, Franmis Y. Dextrine and pectin extracted from vegetal disposals and their use as additive for glue. Rev. Bol. Quim [online]. 2020, vol.37, n.2, pp. 85-93. ISSN 0250-5460.

Abstract Dextrin and pectin extracted from cassava, potato and yam plant residues were used in the formulation of a glue. The plant residues were characterized and the yield was determined for the dextrin extraction process by calcination method (80.0%) and for the pectin extraction by acid hydrolysis (10.3%). Dextrin was characterized by the positive test with iodine and the solubility in water with the absence of reducing sugars. In IR spectroscopy, the characteristic bands of dextrin fiinctional groups were observed. The pectin obtained is low in methoxyl and with a high degree of esterification, which is why it needs the presence of calcium ions to gel. The fiinctional and organo leptic properties of the glue samples were evaluated, with the one formulated with 0.25% pectin showing the best characteristics..
