Quality Characteristics of 4 Year-old Ginseng by Enzymatic Hydrolysis Conditions

Abstract

This study investigated quality characteristics of 4 year-old ginseng by enzymatic hydrolysis conditions to increase utilization. Ginseng was ground after steaming and was each treated with hydrolase A, B, C and D. When quality characteristics by the enzymes were examined, no significant difference was observed with pH of 5.5～5.6 and the sugar content of 4.0～4.33. The crude saponin content was the highest in ginseng treated with D, followed by B, C and A. The crude saponin, the reducing sugar and the total sugar contents increased until 0.3% (w/w) concentration in enzyme D with no significant difference by its concentration. Although active ingredients increased with time passage of hydrolysis, no significant change was found after three hours and the crude saponin content was the highest when ginseng was treated at 60 o C. From these results, optimum conditions for 4 year-old ginseng were 60 o C for 3 hours with 0.3% (w/w) enzyme D, and under these conditions the reducing sugar, the total sugar and the crude saponin contents recorded 18.11, 36.21 and 4.23 mg/g, respectively. Therefore, enzymatic hydrolysis was found to be effective in increasing active ingredients of 4 year-old ginseng with various usages expected.

Panax ginseng Fruit Has Anti-Inflammatory Effect and Induces Osteogenic Differentiation by Regulating Nrf2/HO-1 Signaling Pathway in In Vitro and In Vivo Models of Periodontitis

“…The P. ginseng fruit extract used in this study was obtained through enzymatic decomposition processes such as amylase, pectinase, and cellulase. According to previous reports, this enzymatic decomposition minimizes the destruction of major components more so than hot water extraction, and it has been reported that it can increase the extraction yield of useful components [30,31]. In this study, using this P. ginseng fruit extract, we investigated the inhibitory effect of PGFE on a periodontitis model using the ligature method and induced PG-LPS, which are representative models most widely used in periodontitis research [32,33].…”
