Fruit weight losses are mainly associated with respiration and moisture evaporation through the skin. The results in Figure 1 showed that all fruit samples lost weight during storage; however, the rates of weight loss were significantly greater for uncoated fruits than that of coated fruits. Infact, chitosan coating acts as a semi-permeable barrier to water, resulting in procrastination of water transfer with more control over weight loss and forms a layer of semi-transparent to smooth the surface of pericarp [22]. This coating can also be used as a protective barrier to reduce
respiration and transpiration rates through fruit surfaces [23]. At the end of 14 day, the control group lost 5.5
% of total weight, but samples treated with T1, T2, and T3 lost 4.5%, 3.99% and 3.75% of their total weight
respectively. There was a small difference in the percentage of weight loss within the coated samples, least weight
loss was found for T3. Results were in accordance with [24] in sapota fruits. This quality parameter is quite crucial,
since every loss in weight translates into an economic loss
