OBJECTIVETo explore an economical and practical storage method for angelica roots (Angelica sinensis). Various treatments were used in packaging and storing dry and fresh angelica roots.

METHODThe experiment was designed in single-factor completely random as compared with the traditional stack without package. The character, weight, extract contents and volatile oil were measured within the storage process.

RESULTIf stored for long-term use, the dried angelica roots should be packaged with vacuum-exhausted bags cleaned with water, which resulted in less loss in weight, higher extracts and volatile oil. However, if stored for fresh use, the fresh angelica roots should be packaged in vacuum-exhausted bags after cleaned with sorghum alcohol and stored under low temperatures if possible, which resulted in less loss in weight and longer fresh time. Considering volatile oil and extract contents, it is better to use the dried angelica roots for storage.

CONCLUSIONIf stored for long-term use the dry angelica roots should be packaged with vacuum-exhausted bags cleaned with water, while for fresh use the fresh angelica roots should be packaged with vacuum-exhausted bags cleaned with sorghum alcohol and stored under low temperatures if possible.
