Abstract:

BiotechnologyGreen Leafy Vegetables (GLV) constitutes the treasure trove of nutrients in addition to being cheap and easily available. Dehydration of GLV�??s concentrates nutrients, thus providing nutridense food. Hence an investigation was done with the objective to asses the effect of different drying methods (Sun drying, Microwave drying and cabinet drying) on the GLV�??s. Five types of locally consumed GLV�??s, (Murraya koenigii, Coriandrum sativum, Spinacia oleracea, Peucedanum graveolens, Trigonella foenum graecum) were selected. Dehydration protocol was assessed employing different methods of dehydration. Comparing the dying time and drying rate of the samples it was observed that Microwave drying was superior. Dehydrated curry leaves scored highest in terms of drying rate and rehydration ratio among the selected GLV�??s.
