Summary for Project title: R6316: Small scale starch extraction and storage to improve process efficiency.
Some 60% of the water used in producing starch from cassava can be recycled using a hydrocyclone (a device that separates particles in a liquid suspension). The savings from water extraction offset production costs, and the technology can prove especially useful in areas with growing water shortages. Low concentrations of acetic acid (2%) can also help cassava processors to protect their profits, preventing the growth of micro-organisms in stored starch and thereby helping to maintain its quality. This knowledge addresses two of the major constraints to the cassava starch industry in India, and can be applied in other cassava-producing countries.
