dc.description | The main objective of this research was to evaluate the physicochemical and organoleptic parameters of yogurt made from pasteurized milk, enriched with jackfruit pulp (Artocarpus heterophyllus) and stabilized with cassava starch (Manihot esculenta) as a natural alternative. Six different formulations were developed using varying concentrations of pulp (25% and 45%) and starch (0%, 0.5%, and 1%) to determine their influence on the final product’s properties. The samples were analyzed for pH, titratable acidity, and density, and were also subjected to a sensory evaluation using a hedonic test with 30 semi-trained panelists. The results indicated that treatment T3, containing 25% jackfruit pulp and 1% cassava starch, showed the best physicochemical stability and the highest sensory acceptance in terms of flavor, texture, color, and aroma. The addition of cassava starch improved the yogurt’s consistency, while the jackfruit pulp contributed a natural sweetness and a characteristic exotic aroma. Moreover, the use of natural ingredients was found to not only enhance nutritional value but also offer functional benefits, making this an innovative alternative within the agro-industrial dairy product market. It is concluded that producing functional yogurt using tropical fruit and natural starches is viable, promoting the use of local crops such as jackfruit and cassava in line with healthy and sustainable consumption trends. | es_ES |

dc.description.abstract | La presente investigación tuvo como objetivo principal evaluar los parámetros fisicoquímicos y organolépticos de un yogurt elaborado a partir de leche pasteurizada, enriquecido con pulpa de jackfruit (Artocarpus heterophyllus) y estabilizado con almidón de yuca (Manihot esculenta) como alternativa natural. Se desarrollaron seis tratamientos con distintas concentraciones de pulpa (25% y 45%) y almidón (0%, 0.5% y 1%), a fin de determinar su influencia en las propiedades del producto final. Las muestras fueron analizadas en cuanto a pH, acidez titulable, densidad, además de someterse a una evaluación sensorial mediante una prueba hedónica con 30 panelista semi entrenados. Los resultados indicaron que el tratamiento T3, con 25% de pulpa de jackfruit y 1% de almidón de yuca, presentó los mejores valores en estabilidad fisicoquímica y mayor aceptación sensorial en cuanto a sabor, textura, color y olor. La incorporación de almidón de yuca permitió mejorar la consistencia del yogurt, mientras que la pulpa de jackfruit aportó dulzor natural y un aroma exótico característico. Además, se observó que el uso de ingredientes naturales no solo aporta valor nutricional, sino también funcional, lo que representa una alternativa innovadora dentro del mercado agroindustrial de productos lácteos. Se concluye que es viable la elaboración de un yogurt funcional utilizando fruta tropical y almidones naturales, promoviendo así el aprovechamiento de cultivos locales como el jackfruit y la yuca, en línea con las tendencias de consumo saludable y sostenible. | es_ES |
