Abstract: In present study frozen food product developed from organically vis-a-vis conventionally grown exotic vegetables broccoli and kale. Samples were dived into two lots, first no treatment and second was subjected to water blanching for 2 minutes and then sulphuring by dipping in 2 per cent solution of potassium metabisulphite for 5 minutes. These frozen organic and inorganic broccoli and kale samples were utilized in preparation of traditional recipes like madra and sabji from frozen broccoli and bhujju and katlu from frozen kale which were stored for 45 and 90 days at -18 °C. Frozen food were evaluate for phytochemical contents and prepared recipes were evaluate for sensory acceptability at fresh and after various storage intervals. Results revealed that phytochemical constituents like beta carotene, chlorophyll and ascorbic acid contents in frozen broccoli and kale samples which were blanched before sulphuring were lower as compared to control frozen samples. The results of prepared recipes revealed that untreated frozen samples at 0 day of storage was more acceptable as compared to recipes prepared from treated samples. The sensory acceptability scores of bhujju and katlu prepared from treated frozen samples were significantly higher than those prepared from untreated frozen samples. Among the sources of broccoli and kale, recipes prepared from organic sources was rated better. The acceptability scores of the products prepared from stored frozen samples declined as the storage progressed and the scores ranged between “liked extremely” to “liked very much” on nine point hedonic scale. It is concluded that freezing of broccoli and kale can help to minimize their post-harvest losses. The consumption of broccoli and kale should be promoted to harness their health promoting and health protecting beneficial effects.
