Comparison of Quality Changes of Angelicae Sinensis Radix Treated by Ozone Gas and Sulfur Fumigation
Objective:To provide theoretical basis for the feasibility of ozone treatment technology as a select alternative technology to sulfur fumigation by comparing the quality of Angelicae Sinensis Radix after ozone treatment and sulfur fumigation treatment. Method:Angelicae Sinensis Radix was treated with intermittent ozone gas and sulfur fumigation process
respectively.The content of ferulic acid in Angelicae Sinensis Radix was determined by RP-HPLC.The volatile oil from Angelicae Sinensis Radix was extracted by steam distillation and its chemical constituents were determined by GC-MS.The microbial content was taken as the index
the effect of different treatments on the storage period of Angelicae Sinensis Radix was evaluated. Result:Compared with the untreated Angelicae Sinensis Radix
the content of ferulic acid decreased 23.72% and 34.43% after ozone and sulfur fumigation treatment
respectively.After ozone and sulfur fumigation treatment
the color
content and compositions of volatile oil from Angelicae Sinensis Radix were changed
the amount of volatile oil decreased by 53.85% and 76.92%
the content of ligustilide decreased by 10.65% and 9.32%
respectively.The microbial content in Angelicae Sinensis Radix after ozone treatment was less than that of sulfur fumigation treatment. Conclusion:The changes in chemical composition of Angelicae Sinensis Radix treated with ozone are less than that of sulfur fumigation treatment.It is expected to be an alternative to sulfur fumigation treatment of Angelicae Sinensis Radix.
