Effect of heat pump drying temperature on moisture migration characteristics and quality of instant Tremella fuciformis.

ABSTRACT: Low-field nuclear magnetic resonance (LF-NMR) was used to analyze the moisture migration characteristics and water distribution of instant Tremella fuciformis (ITF) during heat pump drying at 35 °C, 45 °C and 55 °C. A fuzzy mathematical evaluation method was then used to investigate the effect of heat pump drying temperatures (35 °C, 45 °C and 55 °C) on the quality of ITF. Based on the screened appropriate temperature of 45 °C, the thin layer heat pump drying curve and drying rate curve of ITF were drawn, then four mathematical models were tested based on the coefficient of determination (R²). The result showed three water components (bound water (T ₂₁), immobilized water (T ₂₂), and free water (T ₂₃)) in ITF before dr
