|Abstract:||An experiment was conducted to study the effect of different drying media and methods for chrysanthemum var. marigold flowers in the Department of Post Harvest Technology, KRC, College of Horticulture, Arabhavi during the year 2016-17. Among the different media used for dehydration, silica gel was found to be the best with respect to quantitative and qualitative parameters such as minimum dry weight (0.57 g/flower), highest moisture loss (92.90 %), least final moisture retention (1.88 %) and maximum xanthophyll retention (42.35 %) with highest score for colour (4.45), shape (4.40), appearance (4.90) and overall acceptability (4.50) of flowers throughout the storage period. Data on drying of flowers in hot air oven had significant influence on dry weight, moisture loss, final moisture retention and xanthophyll retention. Maximum moisture loss (85.33 %), minimum dry weight (0.49 g/flower) and minimum final moisture (2.07 %) were recorded in the flowers dried at 60ºC. Whereas highest xanthophyll retention (45.10 %), maximum score for colour (4.00), shape (4.50), appearance (4.50) and overall acceptability (4.50) were observed in the flowers dried at lower temperature of 35ºC for 87.00 hrs. This study also revealed that microwave oven drying had significance influence on dry weight, moisture loss and quality parameters. The minimum dry weight (0.87g/ flower) and maximum moisture loss (87.84%) were recorded in flowers dried at lower power density till the flowers completely dry for duration of 15 min. With regard to quality parameters, drying of flowers at medium level for 2 minutes and then at low level for 4 minutes was found to be superior with respect to colour, shape, appearance and overall acceptability (4.05, 4.04, 4.07 and 4.10 respectively) of dried chrysanthemum flowers. The results of the present study suggests that the combination of silica gel + sun drying was found superior in better quality dried chrysanthemum var. marigold flowers.|
