| A study was undertaken to examine the effect of blanching on the dehydration characteristics of unripe banana slices blanched and dried at temperatures 50, 60 and 800C. The effects of pretreatments such as blanching, dehydration and combination treatments on the quality of unripe bananas (Musa acuminata) were investigated. The banana fruits were dehydrated at 50, 60 and 800C in a tray dryer at the air velocity of 2-2.5 m/s. The moisture loss from unriped banana slices sample A1, A2 and A3 was higher at blanching temperatures 500C was 7, 6.91 and 6.86 gram and percentage loss in weight was also higher was 2.38, 2.28 and 2.24%, respectively than the blanching temperatures 50 and 600C The drying rates of all treatments were high at drying temperature 500C... |
