Abstract:

The experiment on post-harvest dipping of guava fruits to increase the shelf life and quality of fruits was done with the concentrations of Potassium permanganate (KMnO¬4) and silver nitrate (AgNO3). The harvested fruits were dipped in 0.5%, 1% and 1.5% of silver nitrate and 300, 600 and 900 ppm of potassium permanganate for 10 minutes and packed in CFB boxes. Analysis was done in terms of physical and chemical characteristics of fruits. The results indicated that the minimum physical loss in weight (1.53%) was observed in the fruits treated with Silver nitrate (1.5%). Maximum specific gravity (0.92) was recorded in fruits treated with KMnO¬4 @600 ppm while maximum ascorbic acid (254.16mg) was observed in fruits treated with AgNO3 @1.5%. Potassium permanganate and silver nitrate was helpful in maintaining the quality of fruits up to 9 days while fruits under control were spoiled on the 9th day of storage.
