  • We evaluated fruity characteristics to select the desirable mulberry varieties for the production of fruit from 2002 to 2003. Tested items were total yield, weight of single fruit, soluble solids and fruit size including length, width, and petiole length. We started yield of mulberry fruits from 27th of May, and continued for two weeks or three weeks according to mulberry varieties. 'Susungppong', 'Cheongnosang', and 'Jeolgokchosaeng(Chungbuk)' were showed high and similar quantity for two years. In weight of single fruit, 'Jeolgokchosaeng(Chungbuk)' and 'Ficus' were 4.6 g respectively. 14 mulberry varieties were showed more than 17 Brix % in soluble solids. From that results, eight suitable varieties such as 'Jeolgokchosaeng(Chungbuk)', 'Dangsang 7', 'Jangsosang', 'Susungppong', 'Suwonnosang', 'Palcheongsipyung', 'Kangsun', and 'Jukcheonchosaeng' were selected for the production of fruit.

  • Recently, as the interest in makgeolli has increased and its products have become more diverse, the need to analyze the flavor of makgeolli has emerged. In this study, we analyzed the volatile flavor components in commercial makgeolli using an electronic nose. Discrimination function analysis suggested differences in flavor characteristics of commercial makgeolli depending on sterilization and type of fermentation starter. According to the variable importance point scores determined by partial least squares-discriminant analysis, it was revealed that sterilization, nuruk, and yeast profoundly influence the contents of ethyl acetate (fruity scent), acetaldehyde (strong odor) and isoamyl acetate (fruity scent), respectively. This result is expected to be a valuable stepstone to the characterization of makgeolli.

  • Eleven strains had been previously isolated from kimchi and identified in our laboratory. The ability of each strain in aroma production was investigated by sensory evaluation. Among them Saccharomyc s sp. YK-17, Saccharomyces sp. YK-18, Saccharomyces sp. YH-3 and Saccharomyces fermentati YK-19 produced fruity flavour. Especially, Saccharomyces fermentati YK-19 produced apple and pineapple-like flavours. Pichia media YK-11, Saccharomyces sp. YK-20 and Pichia chambardii YH-4 produced wine-like flavour. Debaryomyces sp. YK-6, Debarymyces coudertii YK-10, Saccharomyces sp. YK-12 and Pichia haplophilia YH-5 produced alcoholic flavours. Using the good flavour producing strains as starters, various groups of kimchi were fermented, and the sensory characteristics of each group such as odor, taste and total acceptability were evaluated. The acidic odor, moldy odor and taste were reduced by adding starter, while the fresh sourness odor and taste similar to fruity fiavour were increased by starter. Comparing with the control group, these odor, taste and total acceptability were increased in the starter-added groups, such as Pichia edia YK-11, Saccharomyces sp. YK-17, and Saccharomyces,fermentati YK- 19. Saccharomyces fermentati YK-19 added kimchi group was higher siginificantly (P<0.05) than the others at the total acceptability. Volatile compounds of the culture broth of Saccharomyces fermentati YK-19 were analysed by gas chromatography, and 6 species of esters and 4 species of alcohols were identified. Among them, the ester substances which broth largely responsible for the apple-like flavour in the sensory evaluation, were found to be ethyl 2-methyl butvrate, ethyl pentanoate and ethyl acetate.

  • Herein, nuruks derived from non-glutinous and glutinous rice inoculated with Aspergillus oryzae N159-1 (having high alpha-amylase and beta-glucosidase activities) were used to produce Korean alcoholic beverages. The resultant beverages had enhanced fruity (ethyl caproate and isoamyl alcohol) and rose (2-phenethyl acetate and phenethyl alcohol) flavors and high taste scores.

  • The component and content of free sugar in mulberry fruits were evaluated. In all accessions, fructose and glucose were identified as the major free sugar. The ratio of two components appeared in the same level. But CV (coefficient of variation. %) of fructose and glucose were 23.6%, 23.4%, respectively. It might suggest that varietal variation exists in sugar contents. The mean of total free sugars were 9.11${\pm}$2.14%. Among the tested 49 accessions, ‘Geunanosang’ showed the highest total free sugars in 14.67%, whereas ‘Cheongsipyung’ showed the lowest total free sugars in 5.57%. Also fruity characteristics as well as total free sugars to select the desirable mulberry varieties for the production of fruit were researched and analyzed. From that results, four suitable varieties such as ‘Hwansipchosaeng’, ‘Junggojo’, ‘ Kaery-angchosaengsipmunja’, and ‘Geunanosang’ were selected.

  • The objective of this study was to determine sensory profiles of rice confections. The samples used in this study obtained from Korea (traditional Korea rice snack and local specialty rice snack) and three countries (USA, Japan, and China) were evaluated and compared. The sensory characteristics of five kinds of rice confections were evaluated using a sensory test and were analyzed via quantitative description analysis (QDA), principal component analysis (PCA), and hierarchical cluster analysis (HCA). In the descriptive analysis, 10 trained panelists evaluated sensory characteristics consisting of 19 attributes, and there were significant differences (p<0.05) among the 16 characteristics. For the descriptive data, multivariate analysis of variance was carried out and identified differences among the samples. The PCA of rice confections for the first two principal components could explain 85.66% of the variations. The Korean, Japanese, and Chinese rice confections were savory, gritty, and particle-sized, the other Korean local specialty rice confections were fruity, sweet, honey-flavored, compact, and crispy, and those from the USA were glossy, grainy, bright, adhesive, cohesive, crispy, and sweet.

  • To investigate the quality characteristics of domestic $ros{\acute{e}}$ wines marketed in Korea, 11 kinds of wines were purchased at the Korea Wine Festival in 2016. The color, physiological activity, aroma component and sensory evaluations were conducted. The hue value of $ros{\acute{e}}$ wines ranged from 0.592 to 1.990, with the Ro7 of Delaware having the highest value. The brightness of $ros{\acute{e}}$ wines ranged from 42.96 to 94.99, the redness from 3.20 to 59.37, and the yellowness from 8.43 to 24.83. Of the 11 $ros{\acute{e}}$ wines evaluated, 1 was a dry wine and 10 were sweet wines. The average sugar content of the sweet wines was 73.89 mg/mL. Among the organic acid contents, malic acid ranged from 0.214 to 2.903 mg/mL, and lactic acid content ranged from 0 to 3.423 mg/mL. Malolactic fermentation differed, depending on the source. The total polyphenol content of $ros{\acute{e}}$ wines ranged from 50.55 to 99.55 mg%, the anthocyanin content was 2.12 to 213.30 mg/L, and the DPPH radical scavenging activity of $ros{\acute{e}}$ wines was between 73.75 to 90.41%. A total of 41 volatile components were detected, including 7 alcohols, 22 esters, 4 terpenes, 3 acids and 5 other compounds. Of these, 9 compounds had odor activity value(OAV) greater than 1; these were identified as 1-propanol (alcohol, pungent), 3-methyl-1-butanol (harsh, nail polish), ethyl butanoate (strawberry, lactic), isopentyl acetate (fresh, banana), ethyl hexanoate (green apple, fruity), ethyl octanoate (pineapple, pear, floral), ethyl decanoate (fruity, fatty, pleasant), linalool (flower, lavender) and limonene (lemone, orange). As a result of the sensory evaluation, the Ro5 wine made from Campbell Early grape, and having a good color, flavor and taste, was the most preferred.

  • Rutin has many beneficial effects on human health. It was established that rutin antagonizes the increase of capillary fragility associated with hemorrhagic disease, reduces high blood pressure, decreases the permeability of the vessels, and has an antiedema effect, reduces the risk of arteriosclerosis, and shows antioxidant activity. Rutin analysis with mulberry fruits was carried out by high-performance liquid chromatography (HPLC) to reveal the possibility of source of functional food. As a result, mean content of fifty accessions was 0.14±0.050% DW. Among the tested fifty accessions, 'Sabangso' was showed the highest rutin in 0.29%DW, whereas 'Simseol' was the lowest content in 0.05% DW. Also, we researched the change of rutin content according to harvested date. The rutin contents of earlier harvested groups were higher than later harvested groups. Simultaneously, fruity characteristics as well as rutin content were researched and analyzed to select the functional mulberry varieties for the production of fruit. From the six accessions which were contained high rutin content, we selected three suitable varieties such as 'Ficus', 'Kangsun', and 'Palcheongsipyung'.
