Diseño de un proceso industrial para la elaboración de una bebida alcohólica a partir de pulpa guanábana (Annona muricata) y enriquecido con jugo de caña (Saccharum officinarum)

Abstract

The company Comercializadora Allpa Grefa Guayusa Shayary Cía. Ltda. needs to establish a production line to expand the industrialization of soursop (Annona muricata) and sugarcane (Saccharum officinarum) in order to produce an alcoholic beverage, since these fruits are mainly used for the production of pulp and nectars. The project focused on designing an industrial process to produce an alcoholic beverage using soursop (Saccharum officinarum) pulp and sugarcane (Saccharum officinarum) juice, validating its technical and economic feasibility. Deductive, experimental and inductive methods were used to select raw materials, collect data and perform a bibliographic analysis of regulations and techniques. In addition, knowledge of processes and unit operations was applied. The characterization of the raw materials was carried out using practical guides from the ESPOCH laboratories. The following values were obtained for the soursop: total solids 17.68, total ash 0.10, acidity 0.69, pH 3.19 and °Brix 13.08. For sugarcane, the following values were obtained: total solids 5.34 g/ml, total ash 0.09%, acidity 0.17, pH 4.37 and °Brix 17.66. The processes involved included washing, pulping, liquefying, filtering, fermenting, distilling and rectification. The results of the industrial design showed a yield of 5.60% of ethyl alcohol distilled with 30.44 liters of mixed juice, obtaining 2.64 liters at 95 °GL. The validation of the ethyl alcohol produced met the requirements established by NTE INEN 375:2018-03. In conclusion, the project has proven to be technically and economically feasible, with a production cost of $5176.96 and an internal rate of return of 22%. This represents an opportunity to reduce the export of raw materials and increase the production of higher value-added products in the country.
