Four broccoli hybrids, namely Packman, Suhani, Altar and CLX 35100 were assessed to find out suitability of their floret and stalk for dehydration and to know the variation in their physical-chemical constituents. Broccoli florets showed 1.3 times more ascorbic acid and 3 times more total chlorophyll content in comparison to the stalk portion. Florets of hybrid Suhani recorded higher content of total chlorophyll, total carotenoids, total phenols and antioxidant activity and also had better drying and rehydration ratio and less in non enzymatic browning as compared to Packman, Altar and CLX 35100. The stalk portion was found to have considerable amount of physico-chemical constituents. But, the values were manifold lesser than the respective value belonging to that of floret portion in all the hybrids of broccoli. Similarly, dehydrated florets and stalk obtained from hybrid Suhani was found to retain better nutritional quality and sensory score in comparison of dehydrated product obtained from Packman, Altar and CLX 35100, respectively.

Key words: Broccoli, Floret, Stalk, Ascorbic acid, Chlorophyll, Antioxidants, Dehydration
