The control and measurement of the pH was carried out daily for a period of 15 days at a fixed time, and ºBrix were controlled every 3 days for the period of 15 days, the initial pH of 4.5 prior to the adjustment with citric acid and 8, 5 ºBrix which was improving the fermentation conditions until finally reaching day 15 with a pH of 3.87 and 6.40 ºBrix. The organoleptic tests carried out on the must of the alcoholic drink resulted in treatment 4 as the best according to the variables of smell, color and flavor. The physicochemical analysis carried out in the laboratory of the best t₄ treatment (potato bean starch + baking powder) results in alcohol, volumetric fraction 4.04% v / v; higher alcohols 55.68mg / 100ml; methanol 0.36 mg / 100 and furfural 0.38 mg / 100ml, these parameters according to the NTE - INEN 369 determine that if the conditions and requirements to be considered an alcoholic drink vodka are met. |
