Extraction of a biodegradable polymer from second-grade cassava starch.
Cassava is one of the major crops produced in Costa Rica, and as one of the top exporters in the world, there is a lot of competition in its production. In the area of Siquirres, the farmers cultivate cassava as a means for exportation. However, farmers in this area have been losing over 40 % of their cassava harvest yield due to quality control regulations. For exportation purposes, first grade cassava is always the priority, where second and third grades are either sold at a very low price or the clients do not purchase it at all. The hard work and dedication invested into the cassava production without earning the anticipated benefit is quite a challenge and financial loss. The objective of this investigation is to characterize this second-grade cassava being produced in Siquirres according to its physiochemical properties and to extract its biopolymer for possible bioplastic production. The starch of the cassava contains many functional properties, rendering a wide variety of products for industrial and culinary purposes. One main characteristic of the cassava starch is the gel that is formed when heat is applied, and the mixture of this gel with other materials can produce a biodegradable plastic. There is a need now to reduce the use of plastic worldwide, and there are many companies that are now investing in biodegradable plastic to be more ecofriendly.

La yuca es uno de los principales cultivos producidos en Costa Rica, siendo uno de los principales exportadores de yuca en el mundo existen muchas competencias en su producción. En el área de Siquirres, los agricultores cultivan mandioca como medio de exportación, sin embargo, los agricultores de esta área han estado perdiendo más del 40 % de su rendimiento de cosecha de mandioca debido a las regulaciones de control de calidad. Para fines de exportación, la yuca de primera calidad es siempre la prioridad, donde la segunda y tercera calidad se vende a un precio muy bajo o los clientes no compran nada. El arduo trabajo y la dedicación invertidos en la producción de yuca y no obtener la recompensa necesaria es todo un desafío y una pérdida financiera. El objetivo de esta investigación es caracterizar esta yuca de tercera calidad que se produce en Siquirres y extraer su biopolímero para una posible producción de bioplásticos. El almidón de la yuca contiene muchas propiedades funcionales, por lo que rinde una amplia variedad de productos para fines industriales y culinarios. Una característica principal del almidón de yuca es que cuando se aplica calor se forma un gel, la mezcla de este gel con otros materiales puede producir un plástico biodegradable. Ahora existe la necesidad de reducir el uso de plástico en todo el mundo, además, hay muchas empresas que ahora están invirtiendo en plástico biodegradable como un medio para ser más respetuosos con el medio ambiente.
