  • In this study, the antioxidant activities of 27 medicinal herbs and plants were measured. The dried medicinal herbs and plants were pulverized and extracted by water, 15% ethanol, and 45% ethanol, respectively at above $80^{circ}C$ for 90 minutes. The original and diluted extracts were tested for their antioxidant activities by 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical-scavenging activity assay. Cornus officinalis (C) and Scutellaria baicalensis (S) were selected to develop rice wines with higher antioxidant activities, based on the result of the 45% ethanol extraction. The rice wine developed using sample showed the highest antioxidant activity as comparing to those of other commercial rice wines. The rice wine samples were analyzed for titratable acidity, pH, $^{\circ}Brix$, reducing sugar content, color (L, a, b), amino-acidity, and ultraviolet absorption. The preferences for color, aroma, and overall acceptability were determined using a 9-point hedonic scale by 150 consumers. The sweetness, sourness, fruitiness, color, and medicinal herb-taste levels of the developed rice wines were also evaluated, using a 9-point just-about-right scale. The mean overall acceptability score of c (5.54) was higher than that of sample S. Based on the results, the sourness and medicinal herb-taste levels of sample s should be modified to higher levels, and the fruitiness of sample S also needs to be adjusted. For a future study, the final compositions of the developed rice wines will be adjusted for product launching based on the preference test data acquired in this study.

  • This study was performed to evaluate the quality characteristics and the antioxidant activities of yanggeng added with the aged black chestnut inner shells (ACI). The levels of ACI addition to Yanggeng were 0%, 1%, 3%, or 5%. The moisture content and the reducing sugar contents of Yanggeng increased with the amount of ACI. The pH of Yanggeng with ACI decreased with the amount of ACI, but the acidity increased. Depending on the amount of ACI added, the lightness (L) and yellowness (b) values of Yanggeng with ACI decreased in the Hunter color system, and the redness (a) value increased. Textural properties by TPA showed that hardness, springiness and chewiness decreased as increase in the amount of ACI added. Total phenol content in the Yanggeng added with ACI increased with the amount of ACI added. Increasing amount of ACI addition enhanced antioxidant activities of Yanggeng, as evidenced by DPPH radical scavenging activity and hydroxyl radical scavenging activity assays. In the preference test, Yanggeng added with 3% ACI showed the highest overall preference and texture. Based on these results, when 3% ACI was added to Yanggeng the quality characteristics, antioxidant property and sensory properties were excellent.

  • The purpose of this study is to examine whether any correlation exists between the dental health capacity and preferred foods of Korean senior citizens over the age of 65 years. The 5th Korean National Health and Nutrition Survey were used. Tissue health index (T-health), Sound teeth (ST), Functioning teeth index (FS-T), Present teeth (PT), and Missing teeth (MT) were used as variables to assess the dental health capacity of the elderly. Preferred foods of the elderly included 63 foods that were categorized as cereals, pulses and roots, meat and poultry, fish, vegetables, sea algae, fruits, milk and dairy products, cream and sugar, and other foods. For data analysis, the weighted average was taken into consideration to generate planning files, and then complex sample analysis were conducted. For statistical analysis, frequency analysis, t-test, one-way ANOVA, and compound specimen linear regression analysis were conducted. T-health score was significantly high in the group with high preference for cereals, fruits, and other foods. In terms of age and economic status, 65~69 years, 70~74 years, and mid to low range in the income ranges scored high in T-health. ST score was significant in the group that preferred cereals, other foods; the corresponding demographic profiles represent 65~69 years, 70~74 years, and the mid-range income communities. FS-T was significant in relation with a preference for fruits, creams and sugars, other foods; the scores were also high for 65~69 years, 70~74 years, and mid-low to low income groups. PT and MT were significant in the group that preferred cereals and fruits; the same applied for 65~69 years, 70~74 years, and mid-low to low income individuals (p<0.05). Food preferences seemed to vary depending on the dental health state of the elderly, and the dental health state of the elderly may act as a risk factor for nutritional imbalance.

  • We studied the antioxidant activities and quality characteristics of gelatin jelly prepared with different amounts (0%, 0.25%, 0.50%, and 0.75%) of Rehmannia Radix Preparata (RRP) concentrate. The moisture content of the control group was 61.62%, and the acidity and pH were 3.68 and 1.96%, respectively. The reducing sugar content of the jellies ranged from 10.83% to 13.1% (from 35.0 $^{\circ}Brix$ to 37.0 $^{\circ}Brix$). The acidity of the control group was the lowest, followed in order by the 0.25% RRP, 0.50% RRP, and 0.75% RRP groups. The lightness, redness, and yellowness of the Hunter color system decreased with increasing RRP concentrate, whereas the hardness, cohesiveness, and springiness increased with increasing concentrate. The total phenol content was the highest in 0.75%. Antioxidant activities such as DPPH radical scavenging and hydroxyl radical scavenging were the highest with the 0.75% group ($IC_{50}$ value of DPPH radical scavenging activity: 85.42 mg/mL for 0.75%, 484.25 mg/mL for control; $IC_{50}$ value of hydroxyl radical scavenging activity: 54.42 mg/mL for 0.75%, 135.54 mg/mL for control). The sensory evaluation results showed that overall preference and texture were the highest in the 5% addition group. From these results, it was suggested that the optimum amount of RRP concentrate to add to jelly is 0.50%.

  • We investigated the quality characteristics of dohwaju (fermented with peach flowers and branches, a Korean traditional alcoholic beverage) containing different sub-ingredients. During fermentation, the inner temperatures of the added sub-ingredient treatments were higher compared to non-treatment, and only peach branches treatment. showed the highest inner temperature. There were no significant differences in the physicochemical results among the treatments. pH decreased from the first mashing day to the second and then increased slightly until fermentation was terminated. Total acidities showed opposite patterns as compared to pH level. Amino acid contents, soluble solids, and alcohol contents increased steadily until the end of fermentation, whereas reducing sugar contents showed the opposite trend. In a preference survey, DB (only peach branches)-treated dowhaju showed the highest evaluation in terms of taste and overall acceptability with walues of $5.07{\pm}1.38$ and $5.57{\pm}1.16$, respectively. Based on the results of this study, we concluded that only peach branches treatment is optimal for the manufacture of dowhaju. We expect that the quality of dowhaju can be improved by providing basic information concerning its manufacture.
