Evaluation of Drying Methods With Respect to Drying Kinetics and Mineral Contents of Dill and Parsley

Dill (Anethum graveolens L.) and parsley (Petroselinum crispum Mill.) were dried by using sun and oven (۵۰oC) drying methods. Oven drying decreased the drying time approximately ۵۰% when compared to the sun drying method for both herbs. K, Ca, P, Mg and Na were the most abundant elements in dill and parsley samples. Oven-dried samples had higher mineral values than that of the sun-dried samples. Page, Modified Page, Midilli and Küçük and Diffusion approach were shown to give a good fit to the sun drying of parsley. The Midilli and Küçük and Verma models have shown a better fit to the experimental sun drying data of dill. Wang-Singh and Midilli and Küçük models gave the highest r۲ values for oven drying of parsley and dill, respectively.
