QUALITY ATTRIBUTES OF CRISPY BANANA SLICES PRODUCED BY FLUIDIZATION BED PUFFING TECHNIQUE

Banana slices with initial moisture content of 380 % d.b.were dried by fluidized bed puffing technique in order to produce free-oil crispy food.Puffing conditions were varied with 3 parameters, i.e.puffing temperature, intermediate moisture content (initial moisture content before puffing) and puffing time.The samples were dried in a hot air dryer at 90 °C to the intermediate moisture content of 15, 25 and 35 % d.b., before they were puffed in fluidized bed dryer at 170, 190 and 210 ° C for 0.5, 1, 1.5 and 2 min under a superficial velocity of 3.5 m/s, and dried again in a hot air dryer at the same temperature to the final moisture content of 4 % d.b.The results showed that high puffing temperature increased drying rate of banana slices and also resulted in crispy final products in case the intermediate moisture content of 25 % d.b.Long puffing time resulted in crispy products as well, but not dominant.High puffing temperature and long puffing time, however, enhanced browning effect and caused the final products more brown.
