| Existe poca información referente a conservas como tal, contrariamente la información relativa a mermeladas y jaleas es abundante. Por lo anterior, el marco teórico que compone esta tesis, se basa en información relativa a mermeladas. Las mermeladas tradicionalmente se caracterizan por ser alimentos de alta densidad energética, con propiedades sensoriales muy atractivas para los consumidores por su sabor, aroma, color y su estabilidad durante el almacenamiento. En el presente trabajo, los parámetros que nos permitieron evaluar una conserva fueron °Brix, pH, actividad de agua (aw) y viscosidad. Al analizar los parámetros de los tratamientos realizados podemos considerar que los tratamientos T3 y T4 de carambolo 60% - piña 40% cumplen con las características... |

| Four formulations of gabiroba jam were processed, and their physicochemical and functional characteristics, rheological profile and jam acceptance were assessed. The physicochemical and chemical characteristics evaluated were water activity, titratable acidity, pH, reducing and non-reducing sugars, proteins, ashes, dietary fibers, color, and firmness. For functional analyses of the formulations, vitamin C, phenolic compounds and carotenoid contents were determined. The ABTS+ and DPPH· methods were employed to evaluate the antioxidant potential. Rheological analysis was performed in a HAAKE RS 75 Rheoestress rheometer with a plate/plate sensor. The flow curve behavior was adjusted using the Power Law and Herschel-Bulkley models. Sensory analyses were... |
