Abstract: | When considering the sustainability of a business, deciding on the industrial use of starchy raw materials requires more than just the information on their agricultural productivity and starch yield. The main goal of this work was to investigate ten different cultivars to select for industrial applications seeking to minimize residue generation and water consumption in the production of cassava starch. The cassava cultivars that are richer in starch (22.61-22.89 g 100 g−1) generated the smallest amounts of residues (420.63-423.52 kg ton−1 of cassava roots) and required the smallest amounts of water for processing. There is an inverse relationship between the dry matter content in cassava roots and the amount of solid residues generated. One of the cultivars stood out for showing the following features: high starch yield, little tendency for generation of residues, low requirement of water for processing, easiness in the peeling process, and high content of total solids; therefore such features can suggest its use for starch extraction with wastes minimization. |
