Physiochemical Characteristics of &lt;i&gt;Panax ginseng&lt;/i&gt; C. A Meyer Sprout Cultivated with Nanobubble Water and Antioxidant Activities of Enzymatic Hydrolysates

This study aimed to improve the physiological activity and processing properties of ginseng sprouts. We first determined the effect of extraction and fermentation conditions on the antioxidant activity of ginseng sprouts. The optimal extraction conditions were 2 h at 80°C, with water as a solvent. The fermentation strains used were Lactobacillus delbrueckii subsp. bulgaricus KCTC 3635 and Enterococcus faecalis KCTC 3206. We then analyzed the changes in the reducing sugar and alcohol content. In fermented samples, the reducing sugar content was lower and the alcohol content was higher than those in control sample. The cell counts of lactic acid bacteria were higher in the fermented samples than those in the control sample. Fermented samples contained more ginsenoside than the extract samples, and ginsenoside was not detected in the control sample. The total polyphenol and total flavonoid contents were relatively high in the fermented samples, particularly in the sample fermented by E. faecalis. Finally, sensory evaluation revealed that the Yakju prepared using ginseng sprouts fermented by lactic acid bacteria was preferable to other drinks control and ginseng sprouts extracted sample. Overall, it was confirme that the addition of fermented ginseng improved the physiological activity and palatability of yakju, there by improving the quality of yakju.

In this study, the ginseng sprout has produced through smart farm was classified according to its size and divided into above-ground (AG) and below-ground (BG) parts to compare ginsenoside contents and antioxidant activity. In the case of the AG part, the total phenolic contents were the highest at 5.16 mg/ g in medium (M) size and the lowest at 2.23 mg/g in largest (L) size. The BG part also showed the highest content in the M size, but there was no significant difference. Also, the total flavonoid contents were also high in the M size in both the AG (5.16 mg/ g) and BG (1.28 mg/g) parts. The major ginsenosides in the AG part were Re (20.33-24.15 mg/g) > Rd (11.36-27.42 mg/g) > Rg1 (4.48-5.54 mg/g) and the main ginsenosides in the BG part were Rb1 (5.09-8.61 mg/g) > Re (4.48-5.54 mg/g) > Rc (3.11-4.11 mg/ g) in orders. In the case of M size, Re and Rd were approximately 4-and 19-folds higher at 24.15 mg/g and at 27.42 mg/g in the AG part and 5.20 mg/g and 1.43 mg in the BG part, respectively. In addition, F3 and Rh1 were detected in the AG part, but not in the BG part. 2,2-diphenyl-1-picrylhydrazyl (74.95%), 2,4,6-azino-bis (3-ethylbenzothiazoline-6-sulphnoic acid) diammonium salt (94.47%), and hydroxyl (70.39%) radical scavenging activities and FRAP (2.169) assay were the highest in M size than other sizes.
