Abstract
Coriander (Coriandrum sativum L.) is an aromatic and nutritious herb but often wasted due to limited processing. Drying is a common method for extending its shelf life. In the study, coriander was hot water blanched, pureed and dried with varying thicknesses of puree (2, 4 and 6 mm) and water temperatures (70, 80 and 90 °C) to assess drying characteristics, mass transfer and quality of coriander powder. It was noted that the time required for drying decreased as the water temperature was raised from 70 to 90 °C. The mathematical modelling showed that the Exponential two-term model had the highest R2 and lowest RSME and SEE values. Moreover, MR was accurately predicted using MLF-ANN with back-propagation algorithm, outperforming the mathematical model. Mass transfer calculated using Dincer and Dost analytical approach showed Deff and hm in the range of 1.980 × 10−9 to 1.839 × 10−8 m2/s and 1.881 × 10−6 to 5.653 × 10−6 m/s, respectively. Regardless of puree thickness, samples dried at 70 °C exhibited superior quality, followed by those dried at 80 °C and 90 °C. The 2-mm-thick puree, dried at 70 °C, displayed the highest antioxidant activity (82.893%), total phenolic content (20.833 mg GAE/100 g dw), total flavonoid content (11.159 mg QE/100 g dw) and total chlorophyll content (95.306 mg/100 g dw), in spite of a longer drying duration. This method appears favourable for yielding high-quality coriander powders.
