Diseño de un proceso tecnológico para la obtención de antocianinas a partir de la Hibiscus sabdariffa (Jamaica) como un proyecto de emprendimiento .

Abstract

In this research, the objective was to propose a proposal for the development of a technological process for the extraction of anthocyanins from jamaica that is grown in the province of Morona Santiago, in order to create a productive project in this area and thus give added value to this type of crop that is spreading rapidly not only in the Ecuadorian Amazon but also on the coast. It was started from a bibliographic-documentary review, looking for the best extraction techniques of anthocyanins and it was determined that the extraction by leaching with ethanol solvent acidified with 1% citric acid was the most effective, with a pH ranging between 4-5 with a leaching time of two hours. For the calculations, a batch of 250g of fresh jamaica was taken as a starting point, of which it was determined that 45.26 corresponds to the calyxes and 54.74 to the seeds. The mass balance was carried out, obtaining that from 46.26% of fresh matter, 8.03% of anthocyanins are obtained. The financial balance gave an internal capital return of 31%, in a capital return period of 1.8 and a positive net present value (NPV), indicating that the process is viable from the technical and economic financial point of view.
