Process optimization and quality assessment of redistilled Ethiopian traditional spirit (Areke): ethanol yield and zinc contamination control

Abstract This research presents a comprehensive optimization of the ethanol re-distillation process focusing on maximizing ethanol purity while minimizing heavy metal contaminants, particularly zinc. Using a rigorous experimental design, key parameters, holding time, reflux ratio, and temperature, w...
