Item type:Publication, Valorization of Black Plum Peel in Spread Formulation: Optimization of Physicochemical and Sensory Properties via RSM(MDPI AG, 2025-12-23); Plum peel is a major by-product of plum processing and a rich source of nutrients and bioactive compounds. This study aimed to optimize a black plum peel spread formulated with apple puree (20–40%) and plum puree (10–30%) using response surface methodology (RSM). Increasing apple puree up to 30% reduced acidity, firmness, cohesiveness, and consistency while improving sourness and overall acceptability. At 40%, apple puree decreased total acceptability and sourness while slightly increasing texture parameters. Increasing plum puree up to 20% lowered acidity, firmness, consistency, cohesiveness, viscosity, and sourness, but further increases to 30% reversed these effects. Both apple and plum purees enhanced antioxidant capacity in a concentration-dependent manner. The interaction between apple and plum purees notably affected the viscosity of the spread. Overall, plum puree had the strongest influence on texture and color, while apple puree primarily affected sensory acceptance. The optimal formulation was 32.01% apple puree and 28.16% plum puree (R2 = 0.999). Developing a spread from black plum peel demonstrates a sustainable strategy for upcycling fruit-processing waste into nutritious, high-value products. This approach reduces environmental impact, supports circular food production, and creates new opportunities for functional spreads in the health-oriented food markets. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, El tamal lojano como patrimonio vivo de la gastronomía del EcuadorEl patrimonio culinario refleja la tradición y la historia de una región a través de su cocina. La ciudad de Loja, en Ecuador, con sus platos típicos, los cuales han sido elaborados y adaptados a lo largo del tiempo en respuesta a los cambios de consumo. El tamal lojano forma parte esencial de la alimentación de la región, y su preparación facilita la interrelación cultural entre el sector productivo y la sociedad. Esta investigación tiene como objetivo identificar y comprender los procesos y la evolución de los ingredientes que intervienen en la preparación actual y su permanencia en la cocina local, considerándolo un componente importante del patrimonio cultural intangible. La investigación es de tipo cualitativo, utilizando técnicas de observación, entrevistas y revisión bibliográfica. Los resultados obtenidos se analizaron considerando aspectos como la distribución geográfica, los tipos de relleno, la base de la maza y los métodos de cocción.
