  Con el fin de optimizar y cuantificar la aceptabilidad de una mermelada de mango enriquecida con pectina extraída de la cáscara de cacao cultivado en el departamento de Sucre, el experimento fue conducido bajo un diseño completamente al azar con arreglo factorial de dos factores: concentración de pectina (0.2%, 0.4%, 0.6%) y concentración de ácido cítrico (0.1%, 0.3%, 0.5%) con tres repeticiones por tratamiento, para un total de 27 unidades experimentales. Se mantuvieron fijas las variables fruta fresca 65,5% y azúcar 34,0%. El análisis de los datos se hizo mediante un Análisis de Varianza y una prueba de tukey para la comparación de medias. A las 24h de su elaboración se evaluó la aceptabilidad de la mermelada, empleando un panel de 60 personas y una escala hedónica de 7 puntos, donde se obtuvo un valor de 6.75, me gusta moderadamente; concentración de pectina y ácido cítrico: 0.2% y 0.3% respectivamente

  This experiment was conducted in order to optimize and quantify the acceptability of mango jam enriched with pectin extracted from husk of cacao grown in the department of Sucre, Colombia. The experiment was performed using a two-factor, completely randomized design: pectin concentration (0.2%, 0.4%, 0.6%) and citric acid concentration (0.1%, 0.3%, 0.5%). All experiments were conducted in triplicate for each treatment, for a total of 27 experimental units. Variables such as fresh fruits (65.5%) and sugar (34.0%) were held constant. Data analysis was performed using an analysis of variance while the comparison of means was performed by the Tukey's range test. After 24 hours, a test for measuring product acceptability was conducted among 60 people using a 7-point hedonic scale. The survey yielded an acceptability value (I like moderately) of 6.7 for pectin concentrations of 0.2% and citric acid concentrations of 0.3%
