Abstract

To evaluate the effect of infrared color:#ff0078">drying on color parameters, color:#ff0078">essential oil content and composition of German chamomile (color:#ff0078">Matricaria chamomilla L. ), three different infrared intensities (125, 132, and 220 W) with three airflow velocities (0. 5, 1. 0, and 1. 5 m. s-1) on a total of nine treatments were examined in a completely randomized design, and the shade-dried plants were considered as a control treatment. The results indicated that the treatments had significant effects on color:#ff0078">drying time, color parameters, and color:#ff0078">essential oil content. The control (shade color:#ff0078">drying) and the 220 W radiation intensity with 0. 5 m. s-1 air velocity treatments had the highest (2367 min) and lowest (83 min) color:#ff0078">drying time, respectively. With increasing infrared intensity, the main color parameters such as L, a, b, Δ E (total color changes) and BI (browning index) changed significantly, compared to the control; however, increasing the airflow rate caused less variation of the mentioned parameters in all levels of infrared radiation intensity than the control. The highest color:#ff0078">essential oil content (0. 23% w/w) was obtained at 125 W radiation intensity with 0. 5 m. s-1 air velocity and the lowest (0. 12% w/w) was observed at the 220 W radiation intensity with 0. 5 and 1 m. s-1 air velocity treatments. color:#ff0078">essential oil analysis showed that the highest amount of α-bisabolol-oxide A (60. 6%), (Z)-spiroether (16. 5%), and chamazulene (4. 6%) belonged to 132 W radiation intensity with 0. 5 m. s-1 air velocity, 220 W radiation intensity with 0. 5 m. s-1 air velocity, and control treatments, respectively. In general, the results of this experiment showed that due to the decreased duration of color:#ff0078">drying time, color preservation and desired color:#ff0078">essential oil content and composition, the 125 W radiation intensity with 0. 5 m. s-1 air velocity treatment could be a suitable method for chamomile flowers color:#ff0078">drying.
