Resumen: | En este proyecto se utilizó el residuo de mora para la producción de un colorante natural, este pigmento se caracteriza por contener antocianinas, un componente importante que genera una tonalidad roja característica. Para su obtención, se realizaron tres métodos de extracción como son: soxhlet, ultrasonido y microondas. Para el caso de la extracción soxhlet y ultrasonido, se utilizó como disolvente principal etanol en diferentes concentraciones en medio acuoso. Los extractos fueron caracterizados por medio de un ensayo ácido-base y cuantificación de las antocianinas, estos análisis se realizan para identificar el mejor método de extracción y la concentración de etanol que condujo al mayor rendimiento. Entre el método de extracción soxhlet y ultrasonido se identificó que, en cuanto a rendimiento y cantidad de antocianinas totales, el mejor es la extracción soxhlet utilizando como disolvente etanol al 96% (v/v), en el que se obtuvieron 1413.839±4.20 mg de cianidin-3-glucosido/100g de residuo de mora. |
Abstract: | In this project are the blackberry residue for the production of a natural dye, this pigment is characterized by containing anthocyanins, an important component that generates a characteristic red hue. To obtain it, three extraction methods are used, such as: soxhlet, ultrasound and microwave. In the case of soxhlet and ultrasound extraction, ethanol in different variables in aqueous medium were analyzed as main analyzes. The extracts were characterized by means of an acid base test and quantification of anthocyanins, these analyzes were performed to identify the best method of extraction and the concentration of ethanol that led to the highest yield. Among the soxhlet and ultrasound extraction method, it was identified that, in terms of yield and amount of total anthocyanins, the best is the soxhlet extraction using as ethanol 96% (v / v), in which 1413,839 ± 4.20 mg were obtained of cyanidin-3-glucoside / 100g of blackberry residue. |
