Abstract : The present investigation was undertaken to evaluate the effect of paraffin liquid on shelf life and changes in sugar content of mango (Mangifera indica L.) cv. Dashehari during storage period at ambient conditions. The experiment was laid out in Completely Randomized Design with total 9 treatments and three replications. Pooled data of 2009 and 2010 showed that shelf life of whole fruit coated with 8% paraffin liquid could be maintained up to 13 days as compared to without fruit stalk uncoated fruits (7 days) treated as control. The mangoes were analyzed from the day of harvest to 14th day of harvest. Total sugar contents of whole fruit coated with 8% paraffin liquid were found up to 18.54% on 12 day. Similarly higher reducing sugar and non reducing sugar contents were found in whole fruit coated with 8% paraffin liquid having values 7.58% and 10.41% both on 12th day, respectively. All the three sugar contents on the day of harvest were found minimum.
