  • Backsulgi, the most basic type of rice cake, were prepared with the addition of process rice flour at 0%, 10%, 20%, 30%, 40% and their sensory quality and mechanical characteristics were compared. In addition, the changes in the sensory and textual characteristics of Backsulgi were determined while storing them at the temperatures of 4$^{\circ}C$ and 20$^{\circ}C$ for 0, 1, 2, and 3 days. As a result of sensory evaluation, Backsulgi with 30% process rice flour showed the highest score in overall quality, and the one with 10% process rice flour showed higher scores than controls. Backsulgi with process rice flour did not show significant differences in whiteness, graininess, sweet aroma, roasted nutty taste, sweet taste compared with the control even in the longer storage time at 4$^{\circ}C$ and 20$^{\circ}C$. In the measurement of color changes, L value (lightness) was not significantly different, but a value (redness) and b value (yellowness) were increased as the addition of process rice flour increased.

  • The objective of this study was to access the effects of sensory and physical properties of Beandaeduk on 7 different combination methods (three were combined with mung bean and different proportions of water; four were combined with mung bean and various cereals with constant water), and 3 storage periods (0, 1 and 3 weeks at $-18^{\circ}C$). This experiment was consisted of sensory evaluation I (appearance, texture, taste, flavor and overall preference), II (color, moisture, volume, hardness, elasticity, viscosity and ratio materials, off-flavor and oder) and physical analysis of each sample, and questionaire survey of Beandaeduk. In sensory evaluation I except flavor, significant differences (p<0.05) were found among different combination methods of sample. Also significant differences (p<0.05) were found in sample for storage periods, except appearance. In sensory evaluation II, only moisture and oder of samples were significantly different (p<0.05) for storage periods, and there were significant differences (p<0.05) in samples among different combination methods, except elasicity. Stepwise regression for storage periods in sensory I showed that texture and taste were important factors in overall preference of sample. In the questionaire survey, preference and adding materials of Beandaeduk were different according to province. Half of respondents preferred to get instant Beandaeduk and instant mung bean powder.

  • To utilize the leaves of broccoli, the shape of which was similar with that of kale leaves, as a vegetable juice, the extracts from two types of vegetable leaves were subjected to the analyses of proximate com ponents, volatile sulfur compounds, vitamin C and minerals. The sensory evaluation of the juices, prepared from kale and broccoli leaves, were performed by duo trio test and scoring test. Among eight varieties of broccoli, four varieties('Pilgrim', 'Greenbelt', 'Salinas' and 'Shasta')were not significantly different from kale(p<0.05), based on the duo trio sensory test. Sulfur and nitrogen compounds present in the dichloromethane extracts of kale and broccoli leaves 'Pilgrim' were identified as 3 butenyl, allyl, butyl and 4 methylsulfinylbutyl isothiocyanate(sulforaphane), 4,5 epithiovalero, 4,5 epithio 3 hydroxyvalero, benzenepropane, 3 hydroxy 4 propene, 4 methylthio butane, 3 hydroxy 3 phenylpropane, 5 methy lsulfinylpentane, 4 methoxyphenyl 3 hydroxypropane nitrile and dimethyl trisulfide by GC/MSD analysis. Proximate components were observed to be relatively similar between kale and broccoli leaves. Vitamin C and sugar content were higher in broccoli leaves(125∼180mg% and 8∼12°Brix) than in kale(101mg% and 7oBrix). In mineral analysis by AA and ICP Mass, 'Pilgrim' showed a higher content of K, Fe, Mn, Zn and Se. In separate experiment, sensory scores of bitter taste and astringent taste were lower and scores of over all taste and over all acceptability, higher in broccoli('1243') juice than those in kale juice.

  • The objective of this study was to investigate the sensory quality attributes for the development of soy sauce containing Hutgae(Hovenia dulcis Thunb). Aqueous extracts of Hutgae were prepared from different parts such as trunk, twig, and fruit. These extracts were used for determining the antioxidant effect by 2,2-diphenyl-1-picrylhydrazyl(DPPH) radical scavenging activity and sensory evaluation. Hutgae twig and fruit extracts had a strong DPPH scavenging effect compared to Hutgae trunk extract. In sensory analysis, high intensities of roast smell, bitter taste, and astringent taste were observed in Hutgae twig extract, whereas those of sweet smell and sweet taste were predominated within Hutgae fruit extract. Hutgae trunk and fruit extracts obtained higher overall acceptability. Various seasoning items such as anchovy, dried-pollack, katsuobushi, shiitake, radish, and kelp were used to determine the suitable type of soy sauce containing Hutgae extracts regarding the different parts. Hutgae fruit and trunk extracts were evaluated for use as a good source of seasoned soy sauce, and the dried-pollack and radish among the seasoning items were well-matched with Hutgae extracts. From these results, soy sauce containing Hutgae trunk and fruit extracts added to dried-pollack soup may be used as a functional seasoning in order to remove hangovers.

  • Objective: This study aimed to evaluate the physicochemical, metabolomic, and sensory qualities of Chikso and Hanwoo beef during 28 days of wet aging. Methods: Rump and loins from Hanwoo and Chikso were obtained and wet-aged for 28 days at 4℃. The samples were collected at 7-day interval (n = 3 for each period). Physicochemical qualities including pH, meat color, shear force value, and myofibrillar fragmentation index, metabolomic profiles, and sensory attributes (volatile organic compounds and relative taste intensities) were measured. Results: Chikso showed a significantly higher shear force value than Hanwoo on day 0; however, no differences between breeds were found after day 14, regardless of the cuts. Overall, Chikso had more abundant metabolites than Hanwoo, especially L-carnitine and tyrosine. Among the volatiles, the ketone ratio was higher in the Chikso rump than the Hanwoo rump; however, Chikso had fewer alcohols and aldehydes than Hanwoo. Chikso rump showed higher taste intensities than the Hanwoo rump on day 0, and sourness decreased in Chikso, but increased in the Hanwoo rump on day 14. Wet aging for 14 days intensified the taste of Chikso loin but reduced the umami intensity of Hanwoo loin. Conclusion: Chikso had different metabolomic and sensory characteristics compared to Hanwoo cattle, and 14 days of wet aging could improve its tenderness and flavor traits.
