RESUMO
Snack factories produce effluents, which are high in starch and suspended solids. The recovery of starch from effluent shows, besides a significant improvement of the effluent quality, a very promising substrate. Analysis for chemical composition, microscopic examination, colour measurements and viscosity of recovered starch paste were carried out. The result of analysis revealed that, the recovered starch met the Egyptian standards for edible starch. The colour quality was promising and just needs little purification. Recovered potato starch has several interesting, desirable characteristics. These include swelling power that results in high viscosity of the pastes. The excellent colloidal properties of recovered starch suggest a high spreading industrial potentiality in the near future for local market. Microscopic examination supported some of these findings
