Efecto de las condiciones de freído sobre la pérdida de humedad y ganancia de aceite en trozos de ？ame (Dioscorea alata)

the effect of frying conditions on immersion on moisture loss and oil content were studied at different times in two yam varieties: diamante 22 and pico botella. the experimental data adjusted itself to the first order exponential model for humidity transfer (r > 0.9) for both cultivars. the humidity diffusion coefficient for the two varieties of yam fried at 140°, 160° and 180°c for 1 to 9 minutes were 8.11±0.76, 8.2±0.81, and 8.62 ±0.71*10-9 m2/s for the diamante 22 variety, respectively, and 8.32±0.82, 8.38±0.78, 8.54±0.84*10-9 m2/s for the pico de botella variety. activation energy was 24.43 kj/mol for the diamante 22 variety and 21.27 kj/mol for the pico de botella variety. the results showed that there was higher oil absorption after 180 s and at 140°c while taking into account 0.377 kg water / kg solid moisture loss for diamond 22 and 0.410 kg water / kg solid pico de botella at 180°c for 540 s.
