Abstract:

Objective: To produce freeze-dried chips using Codonopsis lanceolata as raw material. Methods: The preparation processing of freeze-dried chips of Codonopsis lanceolata includes pretreatment with cleaning, cutting, thermal peeling and filling, pre-freeze and final sublimation-drying. Results: The optimal thermal peeling parameters were treatment temperature of 100 ℃ and treatment time of 20 min; the optimal drying parameters were material amount of 9.4 kg/m2, heating temperature of 80-65- 45 ℃ and vacuum pressure of 25-100 Pa. Conclusion: The prepared Codonopsis lanceolata chips under these optimal processing conditions have crisp taste, strong aroma and abundant nutrition.
