Resumen
El trabajo de Tesis “Isotermas de adsorción pera el arándano (Vaccinium sp)
deshidratado” tuvo como objetivo determinar las isotermas de adsorción del arándano
deshidratado mediante modelos matemáticos.
Las conclusiones del trabajo fueron:
Las isotermas obtenidas presentan forma sigmoidal, como la gran mayoría de alimentos
Se comprueba que la temperatura influye en el fenómeno de la adsorción, cuando la
temperatura aumenta los contenidos de humedad para un valor determinado del Aw
disminuye.
El modelo matemático de GAB es el que presento mayor correlación con los datos
obtenidos experimentalmente con un r = 0.996 a 20 °C, r = 0.998 a 30 °C y un r = 0.992
a 40 °C, Por otro lado, los valores del error medio relativo fueron: EMS = 2.066 a 20 °C,
EMS = 1.596 a 30 °C y EMS = 3.44 a 40 °C.
Los valores monocapa obtenidos del modelo matemático GAB son: 8,805 g agua/100
g.m.s a 20°C, 8,479 g agua/100 g.m.s a 30°C y 7,928 g agua/100 g a 40°C.
Thesis work “Adsorption isotherms for dehydrated blueberry (Vaccinium sp)” aimed to determine the adsorption isotherms of dehydrated bluberry using mathematical models The conclusions of the work were: The isothems obtained have a sigmoidal shape, like the vast majority of foods. It is found that the temperatura influences te phenomenon of adsorption when the temperature increases the moisture content for given value of Av decreases. The GAB mathematical model is the one that presented the highest correlation with the data obtained experimentally with r = 0.996 at 20 °C, r = 0.998 at 30 °C and r = 0.992 at 40 °C. On the other hand, the error values relative mean were: EMS = 2.066 at 20 °C, EMS = 1.596 at 30 °C and EMS = 3.44 at 40 °C. Single layer values obtained from the GAB mathematical model are: temperature 20°C, 8.805 g water/100 g dry mass, 30°C, 8.479 g water/100 g dry mass and 40°C, 7.928 g water/100 dry mass mass.
