Evaluation of phytochemical contents and physiological activity in Panax ginseng sprout during low-temperature aging

Abstract

To investigate the phytochemical componetns and physiological activity of Panax ginseng sprout (PGS) during low-temperature aging, sprouts were aged at 40 and 60℃ for 0.5, 1, 2, 3, and 4 days. The crude saponin content in PGS aged at 60℃ was found to be higher at an early aging time. However, with aging, the content at 40℃, increased rapidly, and become significantly higher in the PGS aged at 60℃. The total content of phenolic compounds gradually increased with aging, with the highest content being 341.3 gallic acid equivalent (GAE) mg/100 g on day 4 at 40℃ and 431.5 GAE mg/100 g on day 3 at 60℃. Among the ginsenosides, the Re, Rb1, and Rg1 contents were higher and the total content was higher at the early aging time in sprouts aged at 60℃, however, there were no significant differences in the contents on day 4. The 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities increased with aging of PGS. The ABTS activities in PGS aged at 40℃ and 60℃ were highest on day 3 and 2, respectively. Thus, the ginsenoside content and physiological activity of the PGS increased throughout the aging process. The optimal aging temperature and time were 3 days at 40℃ and 2 days at 60℃.

Hygienic effect of modified atmosphere film packaging on ginseng sprout for microbial safety

“…Ginseng (Panax ginseng C. A. Mayer) is a key agricultural crop in Korea and is known for its rich saponin composition and a wide array of pharmacological benefits, including antioxidative, antiaging, antifatigue, antidiabetic, and cardiovascular enhancement properties (Cho et al, 2019;Jin et al, 2007;Seong et al, 2019). To maximize these therapeutic effects, various ginseng derivatives have been commercially developed, including baeksam (white ginseng), hongsam (red ginseng), and taegeuksam (taegeuk ginseng), exhibiting enhanced storage and distribution efficiencies.…”
