Reducing sugar, total sugars and ascorbic acid: Reducingsugars contents gradually increased which might bedue to hydrolysis of total sugars into reducing sugars (Table4). The effect of treatment, duration of osmosis and theirinteraction were signifi cant (p <0.05). Sharma et al. (1997)and Palve et al. (2007) reported similar results in osmodriedapple candy and fi gs on storage, respectively. Asexpected, the total sugars content increased (p <0.05). Thisincrease during storage was a mass reduction effect due toloss in moisture content. Treatment, duration of osmosisand their interaction effects were also signifi cant (p <0.05).Similar results were reported by Palve et al. (2007) in osmodriedfi gs. The ascorbic acid content decreased graduallyduring storage in all the samples, possibly due to oxidationof ascorbic acid to dehydro-ascorbic acid during storage.The effect of storage was signifi cant (p <0.05).The osmo-dried banana slices on storage for 6 monthswere microbiologically found safe (Table 4), which couldprobably be because of addition of KMS, citrate, lowmoisture and high concentration of sugar. The higher TSSand acidity of the product might have also played a role inpreservation of the product.Considering about 20% yield of osmo-dried bananaslices, the cost of production of osmo-dried banana sliceswas nearly Rs 65/kg.
