Post Harvest Investigation on Processing,Packaging,and Storage of Lilii Bulbus / 中国实验方剂学杂志

ABSTRACT

Objective: To investigate the current harvest,processing,packaging and storage of Lilii Bulbus due to the great difference in quality of commercially available products,in order to realize the factors affecting the quality after harvest and provide reference for the standardized production. Method: A series of factors affecting Lilii Bulbus quality were analyzed comprehensively on the basis of both field survey in main producing areas and medicinal material markets and literature retrieval. Result: The current situation and problems in harvest,initial processing,drying technologies,packaging,and storage were summarized. Conclusion: The harvest link of Lilii Bulbus involves growing years,harvesting time,and collecting methods. The initial processing link involves stripping,cleaning,sulfur fumigation,and many cooking and drying methods. The hot-air,vacuum-freeze,far-infrared,and microwave methods are applied in drying Lilii Bulbus. The main metamorphic phenomena are brown staining,moth biting,and decay in the packaging and storage links. Lilii Bulbus are packed mainly in bulk,and a few of them are packed in plastic bags or vacuum bags for fresh bulbus. Because the operation process is not standard,the cooking and drying methods are the key factors affecting the quality of Lilli Bulbus. It is necessary to establish a scientific and unified standard operating procedure (SOP) for controlling the whole process of Lilii Bulbus in multiple links.
