This study was conducted to investigate quality characteristics of Aster scaber to increase the value of functional food resources. To examine quality characteristics of Aster scaber, various factors such as color, texture, fiber, minerals, tannin, crude proteins, crude lipids and sensory quality were determined using physiochemical methods. The contents of dietary fiber were 0.68 g in each 100 g of Aster scaber (freeze drying base). In mineral contents, iron was the highest value in Aster scaber (freeze drying base). The contents of tannin were 35.6 ppm of Aster scaber (fresh base). Aster scaber was shown significant difference in tannin from freeze drying leaf. From the results of sensory evaluation, the age of 30's and 40's showed a better acceptability in blanching. Functional healthy drinks were made from extracts of Aster scaber for relieving thirst and promoting health. The recipe of drinks were decided to establish manufacture condition through the sensory evaluation, color, flavor, taste, and overall acceptability. The shelf-life was established in 18 months through quality was analyzed such as soluble solids, optical density 480, pH, acidity and microorganisms.

This study was conducted to develop a healthy and functional drink using red ginseng, maekmoondong and omija using Saengmaeksan. Since the red ginseng extract was used as a raw material, it was diluted from 1,000 to 1,500 times using distilled water and the highest sensory score was obtained when the red ginseng extract was diluted to 1,500 times. When the red ginseng extract was mired with omija and maekmoondong, there was no difference between the ratio of 1: 20 : 1, 1 : 21 : 1 and 1: 22: 1 (red ginseng : omija : maekmoondong). In case of sweetener, honey showed the highest sensory store compared to sucrose, pear extract apple extract, sucralose and aspartame. Additionally, the sweetness was evaluated using all sweeteners and 10 brix or 11 brix showed the highest sensory score. Therefore, red ginseng extract was first mixed with omija and maekmoondong in the ratio of 1 : 20 : 1, and distilled water was added to 1,500 times of the amount of red ginseng extract. Honey was finally added to the mixture to obtain 10 brix concentration and this was highly acceptable.

Functional healthy drinks were processed with freeze dried powders of ethanol extract from of defatted safflower (Carthamus tinctorious L.) seed cake and some useful components of the drinks were investigated. Yield of freeze dried powder was the highest as 8.42% when it extracted with 60% ethanol (60% EFDP). Each drink contained 0.02% of freeze dried powder and ranged 10.6∼13.8% of soluble solid, 2.90∼3.68 of pH, 0.10∼0.83% of titratable acidity. ‘L’ value of drink-I (DSD-I) was the highest as 94.82$\pm$2.45, ‘b’ and ‘a’ value of drink-V (DSD-V) was highest as 27.15-2.65 and 28.67$\pm$2.69, respectively. Major free sugars of drink were 6015.3∼7918.2 mg% of glucose and 1511.4∼2091.0 mg% of sucrose. The content of citric acid was the highest as 179.2∼981.3 mg%. The content of total phenol in 60% EFDP was 99.17 mg% and that of drink-II(DSD-II) and DSD-V was 307.84 mg% and 224.06 mg%, respectively. Total flavonoid was contained as 50.29 mg% in 80% ethanol extract (80% EFDP) and 125.20 mg% in DSD-V. N-[2-(5-hydroxy-1H-indol-3-yl) ethyl] ferulamide (serotonin-I) was determined as high as 18.81 ppm in 80% EFDP and ranged 2.42∼2.89 ppm in drinks. N-[2-(5-hydroxy-lH-indol-3yl)ethyl]-p-coumaramide (serotonin-II) was determined as 30.17 ppm in 80% EFDP and ranged 3.79∼4.59 ppm in drinks. Acacetin, flavonoid compound were 9.83 ppm in amyloglucosidase hydrosis + 60% ethanol extract (A + 60% EFDP) and ranged 0.98∼1.26 ppm in drinks. Electron donating ability (EDA, %) was measured and compared with 100 ppm BHA as chemical antioxidant. EDA was 93.97$\pm$2.21% in A+60% EFDP, 94.79$\pm$2.26% in DSD-I, 94.69$\pm$1.37% in DSD-II, and 93.83$\pm$1.49% in BHA. DSD-II added with hot water extract solution from Korean ginseng and safflower yellow pigment recorded the highest sensory score.

This study was carried out to develop a functional healthy drink using 60% ethanol of dried Acanthopanax senticosus stem extract (ASE). The preparation, physical activity, anti-oxidant activity, and sensory properties of ASE were investigated. The moisture, crude protein, crude lipid, and ash contents of dried ASE were $6.50{\pm}0.12%$, $5.89{\pm}0.16%$, $1.18{\pm}0.11%$, and $3.03{\pm}0.40%$ respectively. The 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity was $87.42{\pm}1.63%$ at 1/10 folds diluted ASE. In total, 40 male ICR mice were divided into five groups including the control (PBS), positive control (Red ginseng 200 mg/kg/day), and ASE-treated groups at doses of 35, 70, and 140 mg/kg/day for five weeks, respectively. ASE was administrated orally one time per day for five weeks before treadmill exercises, and normal and positive controls were fed PBS and red ginseng extract. In the treadmill test, ASE-treated mice (140 mg/kg/day) could run 1.4 times longer than the control mice. Healthy drinks were prepared with the addition of ASE at levels of 0.97% or 0.49% (A, B, and C type). Among the healthy drinks, the B type (ASE, 0.97%) was revealed to have the highest level of taste and overall acceptability through a sensory evaluation. The brix and pH of the ASE health drink (B type) were 14.9 and 4.51, respectively. These results indicated that the dried stem of Acanthopanax senticosus could be used as a functional material in the health drink industry.

This study was performed to reduce unpleasant taste and flavor of $Gastrodia$ $elata$ Blume as well as to improve utilization as functional food materials using fermentation. The component, antioxidant activity, and taste test were compared between fresh and fermented $Gastrodia$ $elata$ Blume powder (FGP). FGP contained higher level of total fat, protein, mineral, and fiber than raw material. The pH of FGP was higher compared to raw $Gastrodia$ $elata$ Blume powder (RGP), and antioxidant activity was as high as vitamin C regardless material status (raw vs. fermented). This result indicated that its activity was not decreased by fermentation. Dispersiveness and solubility of $Gastrodia$ $elata$ Blume powder was the best in 60-70 mesh. For sensory evaluation, FGP or RGP was mixed with either orange juice or yoghurt. The results showed that overall preference, taste, flavor, texture, and color were better in fermented $Gastrodia$ $elata$ Blume drinks than in raw ones. It is plausible that unpleasant taste and flavor of $Gastrodia$ $elata$ Blume was declined by fermentation. Thus, fermentation can be easily applied to eliminate unpleasant smell in $Gastrodia$ $elata$ Blume, and FGP can be mixed with other beverages to produce healthy food and drinks.
