Glass bottles were found more suitable than PVC, HOPE or HMHO film for storage of mango pulp. The pulp was organoleptically acceptable upto 1 year in glass bottles, 7–8 months in PVC bottles, 2 months in HOPE and 45 days in HMHO pouches. Addition of sodium benzoate to 502 (KMS) was found equally effective for the retention of colour but in its presence, there was a slight increase in non-enzymatic browning and decrease in carotenoid pigments in pulps during storage. Addition of 502 alone helped in better retention of carotenoids and flavour during storage. Low temperature also helped in better retention of carotenoids as well as reduction in non-enzymatic browning in the pulp.
