Background: Ginseng Jeongkwa is a traditional processed ginseng product; however, information on quality differences among commercial products is limited.
Methods and Results: Ten commercial ginseng Jeongkwa products manufactured in Geumsan were analyzed for their physicochemical properties, sugar composition, ginsenosides, total polyphenol content, and DPPH radical scavenging activity. The moisture content ranged from 20.79 to 32.23%, while the combined content of the six quantified carbohydrate components ranged from 60.47 to 82.63%. The total ginsenoside content ranged from 2.46 to 5.26 mg/g, with Rg5 being a major ginsenoside in most products. Hardness varied from 598.05 to 2,593.50 gf. The total polyphenol content and DPPH radical scavenging activity ranged from 4.5 to 14.0 mg GAE/g and 29.4 to 81.7%, respectively. The total polyphenol content was strongly correlated with DPPH radical scavenging activity (ρ = 0.997, P < 0.001), whereas no significant correlation was observed between the total ginsenoside content and DPPH radical scavenging activity.
Conclusions: This study identified considerable differences in physicochemical properties, ginsenoside profiles, and antioxidant activity among the analyzed products. The results provide fundamental information for quality characterization and future standardization of commercial ginseng Jeongkwa produced in Geumsan.
