Drying Temperature Affect the Quality of Dehydrated Mint

The quality of the mint dried at 55, 65, 75, 85, and 95 oC were compared during the drying process. The moisture content and water activity of the mint decreased with the drying time and drying temperature during the drying process. The moisture content of 7.0 % guaranteed the safety of the dehydrated mints from the view of the water activity. The drying temperature of 55 and 65 oC preserved the chlorophyll of the dehydrated mint. Hence, the drying temperature of 55 and 65 oC was a better option to dry the mint.
