dc.descriptionThe objective of this experimental work was to evaluate the physicochemical, microbiological and organoleptic profile of a cocoa mucilage nectar (Theobroma cacao L.) with the incorporation of moringa (Moringa oleifera); 6 formulations were prepared varying the proportion of cocoa mucilage (50-70 %) and moringa (5-10 %) with xanthan gum as a stabilizer. The treatments were evaluated in the statistical program ANOVA by means of pH and °Brix analysis and then in TUKEY to show the differences of the groups among themselves, then the sensory analysis was carried out by a panel of 30 semi-trained tasters and the best treatment was subjected to microbiological analysis. ANOVA analysis showed that there were significant differences in pH (𝑝<0,0002, 𝑅2 =0,89) and °Brix (𝑝<0,0001, 𝑅2 =0,93). All treatments complied with INEN 2337:2008 with a pH range between 3,20 and 3,90 meeting the maximum limit 4,5, in the °Brix only T4 met the minimum of 14 °Brix. T4, which contained 70 % cocoa mucilage, 10 % moringa extract and 0,4 % xanthan gum, was the best formulated, obtaining an acceptability of 96,67 % in sensory evaluation. The microbiological analysis of T4 showed that the mold and yeast counts were <10 CFU/mL, complying with INEN 2337:2008. In conclusion, the incorporation of moringa affected the physicochemical and organoleptic profile of the nectar. It is proposed to evaluate the stability of the product by accelerated aging to estimate its shelf life.es_ES

dc.description.abstractEl objetivo de este trabajo experimental consistió en evaluar el perfil fisicoquímico, microbiológico y organoléptico de un néctar de mucílago de cacao (Theobroma cacao L.) con la incorporación de moringa (Moringa oleífera); se elaboraron 6 formulaciones variando la proporción del mucílago de cacao (50-70 %) y la moringa (5-10 %) con goma xantana como estabilizante. Los tratamientos se evaluaron en el programa estadístico ANOVA mediante análisis de pH y °Brix y luego en TUKEY para mostrar las diferencias de los grupos entre sí, posteriormente el análisis sensorial se realizó a un panel de 30 catadores semi entrenadas y al mejor tratamiento se le realizo el análisis microbiológico. El análisis ANOVA mostró que había diferencias significativas en pH (𝑝<0,0002, 𝑅2 =0,89) y en °Brix (𝑝<0,0001, 𝑅2 =0,93). Todos los tratamientos cumplieron con la normativa INEN 2337:2008 con un rango de pH entre 3,20 y 3,90 cumpliendo el límite máx. 4,5, en los °Brix solo el T4 cumplió con el mínimo de 14 °Brix. El T4 que contenía un 70 % de mucílago de cacao, un 10 % de extracto de moringa y goma xantana 0,4 %, fue el mejor formulado obteniendo una aceptabilidad del 96,67 % en evaluación sensorial. El análisis microbiológico del T4 mostró que los recuentos de mohos y levaduras fueron <10 UFC/mL cumpliendo con la normativa INEN 2337:2008. En conclusión, la incorporación de la moringa afectó el perfil fisicoquímico y organoléptico del néctar. Se propone evaluar la estabilidad del producto mediante envejecimiento acelerado para estimar su vida útil.es_ES
