  • Sensory comparison of the flavor of ginseng teas prepared from concentrated white or red ginseng extract was investigated by multipl comparison test and quantitative descriptive analysis (QDA) on 12 selected descriptions. The white ginseng tea revealed higher intensities in odor and taste than those of red ginseng tea, particularly on earthy and sweet odor and bitter and astringent taste. Increase in sample temperature from $2^{\circ}C$ to $80^{\circ}C$ caused a general increase in aroma and bitter taste. When sucrose added into 3% ginseng tea solution, all of the taste descriptions, most significantly on bitterness and astringency, scored lower except sweetness while the aroma was affected a little.

  • This study was conducted to understand sensory characteristics of commercial functional beverages, to analyze and the drivers of liking and disliking of it by Korean consumers. Descriptive analysis and consumer taste testing were conducted with ten commercial products of functional beverages. Samples were consisted of good for beauty, relieving hangovers, and health tonics. For the descriptive analysis, 45 attributes were developed by ten panelists and it shows differences among the all samples. For the consumer testing, 81 panels evaluated the overall liking, acceptance of appearance, odor, flavor, and texture of 10 samples. As a result, attributes of brightness, yellow color, Nurungji flavor, roasted bean power flavor, and milky texture of functional beverages were positive drivers of liking, but attributes of astringent texture, bitter taste, and viscosity were negative drivers of liking on the commercial functional beverages.

  • This study was performed to investigate flavor modification effects of ${\beta}-cyclodextrin$ $({\beta}-CD)$ inclusion complex on the flavor of Doenjang (Korean traditional fermented soy paste) with various substitution levels of 10, 20, and 30%. Water and protein contents of the substituted samples showed significantly lower values compared to those of control(p<0.05). Results of DSC(Differential Scanning Calorimetry) showed that significantly higher ${\Delta}H$ values (386.03 and 304.23) in the 20 and 30% substituted samples represented the stabilized internal cell structures(p<0.05). Internal structures observed with the scanning electronic microscope tended to be less rough and organized making even and ordered internal cell structures as the substitution levels were increased. Results of sensory evaluation showed significantly higher savory flavor and significantly lower bitter and astringent flavors with the substituted samples compared to those of control(p<0.05). Results from this study showed the substitutions of ${\beta}-CD$ could possibly modify unfavored flavors of Doenjang while keeping the unique, nutritional and functional properties when ${\beta}-CD$ was used as a flavor modifier.

  • The purpose of this study was to develop a seasoned Hwangseoke-jeot(a kind of salted and fermented fish) with chitosan having less fishy smell and salty taste. In order to decrease the fishy smell and increase the palatable taste effectively, four types of seasoning were developed, in which minced ginger, garlic and onion were included. In order to improve the color and flavor of seasoned Hwangseoke-jeot, high-quality powdered hot red pepper was also added in all the seasonings. Seasoned Hwangseoke-jeot type 1 had the oil and roasted powder of sesame, which are known to decrease fishy smell and palatable taste, and was the basis of other seasoned Hwangseoke-jeot. Type 2 had the oil and roasted powder of perilla, which also were known to decrease fishy smell and to increase palatable taste effectively. Type 3 had roasted soybean powder and laver to increase savory and palatable taste. It was developed especially for old and young people who like savory taste. Type 4, containing citron syrup, was for the young and children. All the developed seasoned Hwangseoke-jeot samples had better red color and other sensory properies than the control (S-company's seasoned Hwangseoke-jeot), as tested by colorimetry and sensory evaluation. More than 1% (w/v) of chitosan gave an astringent taste to seasoning, so it is recommended not to exceed 1% (w/v) in the seasoning. The developed functional seasonings of jeot would be applicable to other kinds of jeot.

  • Adolescent menorrhagia is defined as excessive menstrual bleeding from menarche to adolescents. It is a distressing condition both for the patient as well as for her parents. If it is not managed in time itmay pose significant health problems that may leads to blood transfusion. We determined the efficacy of Geru (Red ochre) in controlling the amount and duration of blood flow in patients of Adolescent menorrhagia. This study included 40 teenage girls, who presented with heavy bleeding during menstruation to Outpatient Department, Sameena Maternity Nursing Home, Hyderabad during the year of 2013. Assessment of each case was done by history and Pictorial Blood loss Assessment Chart (PBAC) score. Geru powder was given for 2 cycles and results were assessed. The data was analyzed statistically. The mean PBAC score before treatment was $497.04{\pm}389.92$ and after trial in $1^{st}$ and $2^{nd}$ it was found to be $471.13{\pm}162.18$ and $310.13{\pm}142.15$ respectively. On basis of results it was concluded that single unani drug Geru is enough in controlling bleeding and was found effective by its astringent and styptic properties.

  • Chemical compositions were investigated by harvested months and produced methods. The level of crude protein and crude ash of ginseng leaf tea harvested in July was slightly higher than it harvested in September. However, the level of crude fat and carbohydrate of ginseng leaf tea harvested in September were higher than it harvested in July. The results indicated that the harvest month influenced the chemical composition of the ginseng leaf tea. Also, the level of free sugar was increased when the ginseng leaf team harvested in September was produced by FHT(fermented and then hot-air dried) or HHT(heated and then hot-air dried). The results indicated that the subjects were preferred the color of ginseng leaf tea which was harvested in July. However, they were preferred the aroma and ginseng's aroma which was harvested and produced by HHT in September. Because they responded that the ginseng leaf tea tasted too bitter, it suggested that the taste of bitterness needed to remove. Also, the astringent, the savory, after aroma, and after say cry of the ginseng leaf tea was improved with FHT or HHT, and those results obtained from September's harvest rather than July's. Therefore, the overall quality of ginseng leaf tea which was harvested in September and produced with FHT or HHT were evaluated better than it of DHT(dried on the shade and then hot-air dried).

  • Purpose: This study investigated the quality characteristics of vegetable pancake prepared with various levels of barley flour. Methods: The pH level and spreadability of the batters as well as the color, texture, and sensory evaluation of the vegetable pancake were analyzed. Results: The results show that spreadability of batter significantly decreased as the substitution amount of barley flour increased (p<0.001). The pH level of the batter significantly decreased as the substitution amount of barley flour increased (p<0.001). Redness and yellowness increased as the substitution amount of barley flour increased. For texture, the sample groups with substituted barley flour showed high characteristics of hardness, gumminess, and chewiness. Principal component analysis showed that the sample group with a high substitution amount of barley flour was characterized by relatively high darkness, roasted grain aroma, bitterness, astringent, and chalkiness. Acceptance test found that the sample group with 15% barley flour received higher acceptance than the sample group with 0% barley flour in terms of color, texture, and overall acceptance. Conclusion: Acceptance test found that the sample group with 15% or 30% of barley flour had significantly higher or similar acceptance attributes than the sample group without barley flour, which suggests the possibility of developing vegetable pancake with barley flour.
