Abstract:

Experiment was conducted to evaluate the availability of coriander leaves in off season by dehydration under greenhouse type solar dryer as compared to open sun (control) at three levels each of pretreatments (dipping in a solution containing 0.1% MgCl2 + 0.1% NaHCO3 + 2% KMS in distilled water; blanching in boiling water containing 0.5% sodium metabisulphite, and untreated i.e. control) and loading densities (2.0, 2.5 and 3.0 kg/m2). Sensory evaluation of dehydrated coriander leaves and changes in quality characteristics viz. chlorophyll content, ascorbic acid and rehydration ratio were studied during four months storage. The maximum value of sensory score of overall acceptability (8.5) for dehydrated coriander was obtained for chemical treated coriander leaves in the solution of 0.1% MgCl2 + 0.1% NaHCO3 + 2% KMS and with 2.5 kg/m2 loading density under greenhouse type solar dryer, while minimum score (6.0) were found for open sun drying with boiling water treated samples at 2.5 kg/m2 loading density. Four months storage study of dehydrated coriander leaves revealed losses of 18.9 % in chlorophyll content, 27.22 % in ascorbic acid and 2.84% in rehydration ratio for the dehydrated product under greenhouse type solar dryer, as compared to the losses of 18.6 % in chlorophyll content, 29.0 % in ascorbic acid and 1.91% in rehydration ratio under open sun drying.
