  • For the production of ${\gamma}-aminobutyric$ acid (GABA) contents increased Seomaeyaksuk fermentant, 0, 0.25, 0.5 and 1.0% of monosodium galutamate (MSG) was added in Seomaeyaksuk water extract 15% contained Sikhye and inoculated with Lactobacillus brevis (KI271266). Physicochemical properties were sampling and analyzed at each 1 day during 3 days fermentation. Goes on fermentation periods, the turbidity was gradually reduced, but lightness and the yellowness was increased, redness was decreased. Soluble solid was also decreased. The reducing sugars content were also decreased during fermentation. pH was 4.65-4.83 before fermentation but it was lower 3.15-3.68 after three days fermentation. The GABA contents increased by fermentation periods and it was the highest in MSG 1.0% added sample (354.38 mg/L). Fructose, glucose and sucrose contents were 50-67% decreased at three days fermentation than before fermentation. Among the organic acids, propionic acid, oxalic acid, citric acid and fumaric acid contents were decreased and lactic acid, acetic acid and succinic acid were increased during fermentation periods. Contents of total polyphenol and DPPH radical scavenging activity were the highest in MSG 0.5% added sample. From these results, we confirmed that increasing of GABA content when the manufacturing of Seomaeyaksuk lactic acid fermentation product, is possibile by addition of MSG without affecting physicochemical characteristics.

  • This study was conducted to increase the functionality of Korean traditional beverage, Sikhye. The Sikhye were prepared by supplementation up to 20% of Seomaeyaksuk extract (SE) and saccharification for five hours (h). During the saccharification, turbidity of SE-added Sikhye (SES) was the highest at two hours of saccharification and then lowered gradually. L vlaue of SES did not show significant difference feduring saccharification, and both a and b value of Sikhye were increased as saccharification time passed and SE addition ratio was increased. The pH before saccharification was not significantly different by SE addition ratio but it was increased to 5.68-5.73 at 5 h saccharification. Soluble solid, total sugar and reducing sugar contents were enhanced as saccharification time and SE addition ratio were increased. The total phenolic compounds contents and DPPH radical scavenging activity showed a similar trend by saccharification time and SE addition. In sensory test, the evaluations of 5% SES and control were not significant different, but 20% SES group showed significant lower evaluation than other groups because strong color and mugwort flavor. From all of these results, physicochemical characteristics and antioxidant activity of SES was improved by SE addition but sensory characteristics was lower. Acceptable addition ratio of SE in Sikhye is determined to be within 15%.

  • This study was carried out to investigate the quality characteristics of vinegars containing jaceosidin and eupatilin using Artemisia argyi H. ethanol extract (AEE). 10% malt extract (ME) and water extract of Artemisia argyi H. (AWE) were also prepared for vinegar production. Three kinds of materials were mixed in the same amount to prepare vinegar as follows; CO (ME, water, 18% edible ethanol), SE (ME, water, and AEE), SW (ME, AWE, and 18% edible ethanol) and SM (ME, AWE, AEE). All samples were fermented by Acetobacter pasteurianus A8 at $30^{\circ}C$ for 25 days and analyzed at 10, 15, 20 and 25 days. The pH decreased significantly during the fermentation. pH was lower in SE and SM than CO and SW. The acidity increased significantly during the fermentation, and was highest in SM (4.44%) at 25 days of fermentation. The concentration of acetic acid was higher than other organic acids for all vinegars. Jaceosidin and eupatilin were not detected in both CO and SW, but both were detected in the SE and SM. At 25 days of fermentation, jaceosidin and eupatilin concentrations in SE and SM were 6.49-6.88 mg/kg and 2.23-2.24 mg/kg, respectively. From these results, we confirmed that production of vinegar containing jaceosidin, eupatilin and phenolic compounds can be prepared by using Artemisia argyi H. edible ethanol extract.

Effects of Seomaeyakssuk (Artemisia argyi H.) Vinegar on Lipid Metabolism in Rats Fed a High-Fat and High-Cholesterol Diet (섬애약쑥 식초가 고지방-고콜레스테롤 급이 흰쥐의 체내 지질대사에 미치는 영향)

  • The effects of orally administered Seomaeyakssuk (Artemisia argyi H.) vinegar on lipid metabolism in Sprague-Dawley rats fed a high-fat and high-cholesterol (HFC) diet were analyzed. The experimental animals were divided into five groups: a normal diet group (normal, N), HFC diet group (control, C), HFC diet with lovastatin at 20 mg/kg body weight (B.W.) group (positive control, PC), HFC diet with malt vinegar group (TM), and HFC diet with Seomaeyaksuk vinegar group (TS) (2 mL/kg B.W.). After 4 weeks of feeding rats the experimental diet, contents of serum total lipids and total cholesterol levels of TM and TS groups were significantly lower than those of the PC group. Triglyceride contents of the TM and TS groups were not significantly different from those of the PC group but significantly lower than those of the C group. Content of serum high density lipoprotein-cholesterol was significantly lower than that of the N group but higher than that of the C group. Low density lipoprotein-cholesterol content of serum was 190.68 mg/dL in the TS group, which was the lowest except for the N group. Aspartate transaminase and albumin transaminase activities as a measurement of liver damage index were not significantly different between the TM, TS, and C groups. Serum thiobarbituric acid reactive substance content of the TS group was reduced to a similar level as the N group but was lower than that of the C group in the liver and significantly higher than that of the N group. Antioxidant activity of the TS group was 55.69% in serum, which was a similar to that of the N group, and was 52.39% in the liver, which was not significantly different than that of the C group. From these results, we conclude that Seomaeyakssuk vinegar improves serum lipid content as a result of the complex action of vinegar, an active ingredient of Seomaeyakssuk and a product of the fermentation process.
