Abstract:
Coriander (Coriandrum sativum L.) belonging to the Apiaceae family, holds significance is primarily cultivated year-round for its seeds. The economic value of seed spices hinges on their physic- biochemical attributes. This study investigates the impact of cryogenic grinding temperatures (-30 °C, -60 °C, -90 °C) versus ambient grinding on coriander seed powder. Particle size decreases progressively with lower cryogenic temperatures (0.596 mm, 0.523 mm, 0.463 mm for -30 °C, -60 °C, -90 °C, respectively), contrasting with ambient grinding (0.81 mm). Cryo-ground powders exhibit higher bulk densities (565 kg/m³, 688 kg/m³, 754 kg/m³ for -30 °C, -60 °C, -90 °C, respectively) than ambient ground (489 kg/m³), indicating greater compactness. Flowability, measured by angle of repose, decreases with temperature (31º, 28.3º, 25.6º for cryo-ground powders; 34º for ambient). Moisture content diminishes as temperature drops, with cryo-ground powders at -30 °C, -60 °C, -90 °C holding 6.786%, 7.07%, 7.73% moisture, respectively, versus 6.395% for ambient. These findings reveal the intricate correlation between cryogenic grinding and diverse attributes of coriander seed powder, informing potential optimizations for product quality and features.
