This study investigated the possibility of producing juice by hydrolyzing acha starch using crude amylase from germinated maize. Planted maize was monitored for seven days to determine germinative capacity and amylase activity of the seed. Extracted acha starch was hydrolysed using wet homogenised maize seedlings in an incubator at 62-68 °C for 6-8 hours. Colour, pH, titratable acidity (TTA), °Brix and sensory attribute of the juice were determined using standard method. A commercial malt beverage was used as reference. The maize sample had a mean capacity of 95% while its maximum amylase activity occurred at day 4. The pH, TTA, and °Brix of the juice were obtained as 4.5, 0.85 and 10 respectively. Colour values for L*, a*, and b* were 37.64, 7.6, and 15.3 respectively. Sensory analysis showed no significant difference between the juice and reference sample in terms of taste and colour. However, significant differences were observed in aroma and overall acceptability. Hence, malt beverages can be produced using this method but requires certain additives to impart prevalent aroma associated with malt beverages.
