Abstract
Pretreatment followed by low‐temperature low humidity drying was explored for ef‐ ficient dehydration of coriander foliage to retain its quality characteristics. Newton, Page, Handerson & Pabis, Logarithmic & Midilli and Kucuk models were used to study the drying kinetics. Hygienic shelf‐stable green dried coriander foliage (HSSGDCF) obtained was evaluated for their flavour, physico‐chemical, microbial and sensory qualities during storage at ambient (65% RH, 27 ± 1°C) and accelerated (92% RH, 37 ± 1°C) conditions for 90 days. Logarithmic model with higher (R2 = 0.9997) and lower root mean square error value (0.0050) showed the best‐fitted model. Major volatiles identified in HSSGDCF were decanal (5.103%), 2‐decenal (10.021%), do‐ decanal (7.314%), 2‐dodecenal (7.684%), tetradecanal (8.509%), 13‐tetradecenal (19.393%) and decanoic acid decyl ester (6.051%). Degradation of chlorophyll, ca‐ rotenoid and colour values were higher at 37 ± 1°C during storage. HSSGDCF was found to be microbiologically safe and sensorily acceptable at the end of 90 days at 27 ± 1°C.
