A study was conducted to investigate the effect of cube size (2, 3, 4 cm³) and sugar concentration (40, 50, 60ºBrix) on osmotic dehydration of pineapple. Moisture loss, weight loss, solid gain and dehydrated yield during osmotic dehydration of pineapple were studied with respect to cube size and sugar concentration with sample to solution ratio 1:4 with soaking duration of osmotic solution 18 hours. It was observed that Higher moisture loss (27.10), weight loss (12.00), solid gain (15.09) and dehydrated yield (21.06) was observed in 2 cm³ cubes steeped in 60ºBrix sugar syrup for 18 hours and lower moisture loss, weight loss, solid gain and dehydrated yield was observed in 4 cm³ cubes steeped in 40ºBrix sugar syrup for 18 hours. It was also observed that decrease in cube size and increase in sugar concentration significantly increases moisture loss, weight loss, solid gain and dehydrated yield.
