Pre-treatments modulate drying characteristics, moisture removals, pigments and browning substrates, flavor, and microstructure in hot air dried daylily (Hemerocallis citrina)

Introduction Hot air drying (HAD) of daylilies frequently results in prolonged drying. Severe browning, pigment degradation, and unacceptable colchicine retention, compromising both safety and market value. Selecting an appropriate pretreatment is key to mitigating these quality losses while enhancing drying efficiency...
