Abstract: The effects of plate temperature and coriander weight of freeze-drying on lyophilizing time, sample quality andproductive forces were investigated.Lyophilizing time decreased 15.68% as the plate temperature increased 10℃;however,coriander got the hay flavour when the temperature was over high. Lyophilizing time increased 2.5~3h as coriander weightincreased 100g per layer.Lyophilizing time required 12.5h at a plate temperature of 40℃with coriander weight of 400g per layer.The quality of the lyopilized sample was superior to that of the vacuum dried sample, the former after redehydrating was closeto the fresh sample.

Key words: coriander, freeze-drying
