Comparación de diferentes formulaciones para obtención de biopolimeros a partir de almidón de yuca (Manihot esculenta).

Abstract

The following research project aimed to conduct a comparative analysis of different formulations for obtaining biopolymers from cassava starch through a systematic literature review. The study was carried out with thorough and detailed research of documents considering their relevance, completeness, and timeliness. As a first point, different scientific publications about the formulations for elaborating biopolymers from cassava starch were compiled. The reported physicochemical properties of the biopolymers were compiled, and as a final point, the relationship between the formulations used and the properties presented by the biopolymers was discussed. The biopolymer formulations from cassava starch are mainly composed of distilled water with more than 50%, followed by cassava starch with a range of 10 to 25% and plasticizers from 3 to 5%. A biopolymer's main physicochemical and mechanical properties are density, tensile strength, elongation, deformation, solubility, humidity, gelatinization temperature, and biodegradability in soil. The formulation is directly related to the physicochemical and mechanical properties of a biopolymer, being the content of the raw material the one that will provide these characteristics. It is concluded that biopolymers from cassava starch can present similar characteristics to conventional polymers, so their use in the industry is recommended to conserve the environment.
