Cassava Starch as an Effective Component for Ideal Biodegradable Plastic
Title: Cassava starch as an effective component for Ideal Biodegradable Plastic Proponent: Zhaira Morysette L. Maco, III-Narra student Introduction:
Inventions have evolved and continue to evolve such that after several years of study, research and experimentation reach great developments. With continuing efforts to investigate the constituents of Philippine plants, we have pursued investigation of starch of the cassava plant (Manihot esculenta). Cassava tubers were gathered, ground and squeezed to extract starch. Cassava (Manihot esculenta), also called manioc, tapioca or yuca, is one of the most important food crops in the humid tropics, being particularly suited to conditions of low nutrient availability and able to survive drought (Burrell, 2003). The plant grows to a height of 1 to 3 m and several roots may be found on each plant. Although cassava leaves are sometimes consumed, the major harvested organ is the tuber, which is actually a swollen root. The plant is propagated mostly from stem cuttings. A major limitation of cassava production is the rapid post harvest deterioration of its roots which usually prevents their storage in the fresh state for more than a few days (Okezie and Kosikowski, 1982).
Cassava ranks very high among crops that convert the greatest amount of solar energy into soluble carbohydrates per unit of area. Among the starchy staples, cassava gives a carbohydrate production which is about 40% higher than rice and 25% more than maize, with the result that cassava is the cheapest source of calories for both human nutrition and animal feeding. A typical composition of the cassava root is moisture (70%), starch (24%), fiber (2%), protein (1%) and other substances including minerals (3%)
Compared to other crops, cassava excels under suboptimal conditions, offering the possibility of using marginal land to increase total agricultural production (Cock, 1982). Plant breeders, agronomists and recently molecular biologists have made
