Comparación de diferentes dosificaciones para la obtención de un biopolímero a partir de almidón de quinua

Abstract

This research focused on the development of biopolymers based on quinoa starch. Three levels of distilled water (175, 200, 225 ml) as a hydrating and plasticizing agent, along with three levels of glycerin (25, 20, 15 ml) performing as a plasticizer, and acetic acid (19 ml) incorporated as a stabilizer and chemical modifier. All this mixture, followed by Carboxymethyl cellulose (CMC or Ig) working as a thickener, was also included. These values of the formulation were blocked using a completely randomized block design, resulting in 9 treatments with three replications each. After getting these formulations, the biopolymers were created, which resulted in some prototypes for subsequent analysis. Mechanical, chemical, and functional characterizations were essential to test the developed biopolymers. After performing these characterization analyses, the most effective treatments were determined through statistical analysis using the Info Stat program. Finally, it was possible to determine that water levels did not significantly differ in influencing the biopolymer characteristics, whereas glycerin levels showed significance, influencing the behavior of the biopolymer due to its role as a plasticizer.
