Objective:
To study the feasibility of the application of ultra high-pressure processing (UHPP) as an anticorrosion and anti-mould method by comparing the total numbers of bacteria and mould colonies and the content of ginsenosides before and after UHPP.
Method:
The total numbers of bacteria and moulds colony were determined by microbiological test method. The contents of 12 ginsenosides were determined by HPLC.
Result:
Under the three selected conditions, the total number of bacterial colony decreased significantly, while the mould was not detected in UHPP samples; and the contents of 12 ginsenosides were increased significantly in methanol extracts and water extracts.
Conclusion:
UHPP not only shows anticorrosion and anti-mould effects, but also enhances the leaching rate of ginsenosides. It is a highly effective, safe and environmental friendly anticorrosion and anti-mould technique for Ranax ginseng worth in-depth study.
Insights
Ultra-high pressure processing (UHPP) effectively inhibits bacteria and mold in ginseng. This innovative method also increases the extraction of beneficial ginsenosides, offering a safe and eco-friendly preservation technique.
