“Diseño del proceso industrial para la obtencion de una bebida alcohólica tipo vodka a partir de papa china (colacasia esculenta) para la cervecería nefer”

Abstract

The main objective of this graduation work was to obtain a vodka-type alcoholic beverage from the Chinese potato (Colacasia esculenta), since this is a tuber produced on a large scale, but little used in the food industry. For this purpose, an industrial process was designed to obtain the alcoholic beverage, where first the raw material was characterized based on the Ecuadorian standard INEN 1 516, and then the starch was obtained and subsequently the process variables were identified and the engineering calculation was continued based on the process variables. Once the process of obtaining the vodka was completed, the technical and economic validation of the proposed design was carried out through the physical, chemical and sensory characterization of the product based on the INEN 369 standard (ALCOHOLIC BEVERAGES. VODKA. REQUIREMENTS), with a sample of 250 ml of vodka in the Multianalítyca S. A. laboratory. The following results were obtained: 40° GL, 0.20 mg/100 cm^3 of methanol, < 0.01 of furfural mg/cm^3 and 0.7 mg/cm^3 was obtained of superior alcohols. Before carrying out the studies, a drink of high alcoholic degree was obtained, but by means of the dilution a vodka of 40°GL could be obtained, where, by means of all the tests carried out it is concluded that the alcoholic drink type vodka is acceptable and could compete with other brands already established in the market. The economic validation was carried out with a production cost of ($5.17); PVP ($6.01) with a fixed investment of 38535.00, annual income of 93756, NPV 39606.85 and a recovery period of one year, resulting, that the implementation of the project is feasible.
