Abstract : The aim of research was to evaluate the efficacy of chitosan, calcium chloride separately and in the combination (hurdle technology) as an effective preservative for the increase of the shelf life period of mango (Mangifera indica) during storage. Fruits were harvested from mango-farm of Gwalior (M.P.) at the matured stage. Treated fruits and controls were stored at 15±1°C and 85% RH with chitosan and calcium chloride separately and 60 days shelf life was recorded. But 65 days shelf life period was noticed when treated with chitosan and calcium chloride in combination i.e with hurdle technology. Fruit firmness, weight loss, skin color, microbial counts, total soluble solids (TSS), and total titratable acidity (TTA) were evaluated. Calcium chloride was notably more effective when applied in combination of chitosan. But in all the controls, the decaying process was started after 7 day in similar conditions.
