| Popis: | Kerala, the Indian state has the distinction of producing the earliest mangoes in the country, in February and the season extends up to May, coinciding with South West monsoon. Mango cultivar ‘Neelum’, the last commercial variety to attain maturity in the State is hampered by the incidence of fruit fly and anthracnose disease. An attempt was made during 2019-20 to extend the availability of the fruits of this cultivar by giving a surface coating with ‘Nipro Fresh’ wax containing the fungicide, Carbendazim, followed by shrink-wrap packaging in trays made of areca nut leaf sheath, before sanitizing with chlorine (100 ppm) and alum solution (1%). Surface coating with ‘Nipro Fresh’, followed by shrink-wrap packaging of trays containing mangoes, and their subsequent storage in cool chamber at 12-13 °C and 85-90 % relative humidity, extended the shelf life by 54 days, compared to the uncoated and unwrapped samples which had a shelf life of 9 days under ambient conditions. Respiration rate, physiological loss in weight, total soluble solids and carotenoids showed a steady rise while titratable acidity, total phenols and ascorbic acid recorded a declining trend. |
