Area of Science:

  • Phytochemistry
  • Biotechnology
  • Food Science

Background:

  • Panax ginseng is cultivated for its medicinal properties, affecting the immune system, blood pressure, and cancer.
  • Major ginsenosides transform into more bioavailable and bioactive minor ginsenosides through structural changes.
  • Hydrothermal processing aims to increase yields of transformed ginsenosides (e.g., 20(S)-Rg3, Rk1, Rg5) and enhance antioxidant activities.

Purpose of the Study:

  • To optimize ginseng preparation using hydrothermal processing for increased transformed ginsenoside yields.
  • To enhance the antioxidant activities of ginseng extracts.
  • To compare the efficacy of hydrothermal processing with conventional steaming methods.

Main Methods:

  • Ginseng extract underwent hydrothermal processing in batch reactors at 100-160°C.
  • Quantitative ginsenoside analysis was performed using High-Performance Liquid Chromatography (HPLC).
  • Antioxidant activity was assessed via radical scavenging assays and phenolic antioxidant evaluation, with red and sun ginseng prepared by steaming as controls.

Main Results:

  • Hydrothermal processing yielded 2.5-25 times more transformed ginsenosides than steaming under homogeneous conditions.
  • Antioxidant activities increased 1.6-4 fold with hydrothermal processing.
  • Reaction times were reduced from 3 hours to 15-35 minutes.

Conclusions:

  • Hydrothermal processing offers substantial advantages over conventional steaming for ginseng preparation.
  • Temperatures exceeding 140°C during hydrothermal processing rapidly yield high amounts of transformed ginsenosides with enhanced antioxidant capacity.
