Resumen:
Starch is the most abundant reserve polysaccharide in plants and as such is a renewable resource with many practical uses. Starch is biodegradable, produced in abundance at low cost and can exhibit thermoplastic behavior. The botanical sources are seeds, roots and tubers in which starch arises as an organized structure - granules which are insoluble in cold water. The main commercial sources of starch are maize, potato and tapioca; however, there are a significant number of species that have high starch contents including legumes of grain (e.g., amaranth) and various nuts. Starch properties depend on the source, granule size distribution and morphology, genotype, amylose/amylopectin ratio and other factors like composition, pH, and any chemical modifications. In starch-based products, gelatinization and reorganization behaviour control the texture and stability of the final product [1-6].
