  • This studies were engaged to investigate the potential us of Curcuma aromatica Salab. as a food ingredients. The antimicrobial activity of Curcuma aromatica Salab. extract (CE) and effect on shelf life of the cooked rice were examined. The antimicrobial activity of CE showed apparently against Bacillus cereus, B. subtilis and B. megaterium. The minimum inhibitory concentration (MIC) of CE was 0.15% for B. cereus md 0.2% for B. subtilis and B. megaterium. The antimicrobial activity of CE remained relatively high after heat treatments(30 min at 80 and $100^{\circ}C$, 15 min at $121^{\circ}C$). The shelf life of cooked rice containing above 0.05% CE increased more 1 or 2 days than that of control at $30^{\circ}C$, The texture of cooked rice was improved by addition of above 0.01% CE. The sensory quality of cooked rice with CE did not show significant difference between 0.00% and 0.05% in taste and overall acceptability but decreased above 0.10% in taste, color, flavor and overall acceptability.

  • In order to improve the utilization of seaweeds, two kinds of mixed seasoning concentrates (KMS, MKS) were prepared with Kjellmaniella crassifolia and Mytilus coruscus as main ingredients. Fermentation experiments were carried out at $4^{\circ}C$ for 70 days with Kimchi. As a result, SK-A showed a decrease in pH and an increase in acidity. Salinity was not significantly different after 70th day. Reducing sugar content was higher in mixed seasoning group. Lactic acid bacteria Leuconostoc sp. and Lactobacillus sp. Increased in the control group after 20 days of fermentation. The lightness was higher in the control group from the early stage of dipping to 30 days, and the degree of yellowing was higher than that of SK-B group from 20 days. The hardness of the SK-A group was high at the early stage of immersion and at 10th day. The content of aspartic acid and glutamic acid in free amino acid SK-A group was significantly higher (p<0.05). The content of sweet amino acids was significantly higher in the SK-A group on the 0th, 10th, and 30th days of fermentation than the other groups (p<0.05). The sensory test results showed that SK-A showed the most favorable taste. As a result of reviewing the above results, it is expected that SK-A group immersed in 100 g of seasoning liquid KMS made from Kjellmaniella crassifolia and Mytilus coruscus as a subordinate material will provide taste and nutrition to consumers.

  • The purpose of this study was to analyze consumer consumption and product concept demands of Korean rice-wine. An online survey, conducted from April 28, 2010 to May 6 2010, targeted 200 consumers in Seoul and the Gyeonggi-do area. More than half of the respondents (51.3%) drank rice-wine because of the taste. The common reasons for dissatisfaction with rice-wine were hangovers (35.7%) and taste (16.9%). From analyzing rice-wine preferences, the most preferred ingredient was rice (57.8%), while the most preferred aroma and taste was derived from the fruit (48.7% and 58.4%, respectively). The most common methods consumers observed for promoting rice-wine consumption were the "development and management of rice-wine brands" (59.7%), and "continuous promotion" (44.8%). The most important attributes of a rice-wine product included its taste (4.60), followed by its quality (4.41) using 5-point Likert scale. An importance-performance analysis (IPA) was performed for the 17 attributes of rice-wine and identified targets for product management strategies, including the "usage of domestic ingredients", "ease of purchase", clarity of "product information", and "external image". Therefore, developing solid concepts in marketing strategy are required and may be achieved by understanding the consumer preferences and demands of rice-wine.

  • 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.

  • This study was conducted to provide data on awareness and use of traditional foods, suggesting the desirable ways to succeed and develop traditional foods, and the possible direction of policies and applications for food industry. The study also aimed to figure out awareness of traditional food and dietary life behaviors of married women in order to offer or draw attention to new information for better healthy life styles. Five hundred and ten married women in parts of Seoul and Kyongki area were surveyed to figure out their awareness and use of traditional foods including some of fermented foods, such as Kimchi, Doenjang(soybean paste), and Gochujang(hot pepper paste). The results were summarized as follows. First the overall satisfaction degree with traditional foods reached as high as 74.4%. They preferred traditional foods because they are healthy(38.8%), seasonally celebrated(29.9%), and well known for a variety of fermented foods(28%). Second, Kimchi, Doenjang and Gochujang, home-made or factory manufactured in an old-fashioned way, were preferred. Third, the most frequently cooked traditional foods were Kimchi Chigae and Doenjang Chigae. The most preferred cooking methods using Gochujang were Jorim(stewing) and Bokkeum(roasting). These results showed that Kimchi, Doenjang, and Gochujang were still used in cooking by married women in parts of Seoul and kyongki area, which says those are still the traditional foods most of women think as important and essential. The producers of traditional foods have to consider the safety and improvement of taste and quality of ingredients in addition to the convenience in cooking, More researches should be conducted to enhance these aspects and to develop functional foods to satisfy various needs of consumers and to improve their health.

  • Jujube is a functional food, containing medicinal ingredients without side effects. Jujube can relieve digestive upset, inhibit tumor growth and protect the liver. It includes sterols, alkaloids, saponins, vitamins, organic acids, and amino acids. Jujube has also received attention as an anticancer agent and as a diet food. However, it is rare to find yogurt made with jujube, so we considered adding jujube powder to yogurt to popularize it as a new health food. We made yogurt with jujube powder at 0, 1, 2, 3, and 4%. We measured pH, acidity, color properties (brightness, redness, yellowness), viscosity, sensory qualities (color, flavor, taste, overall quality). We also experimented with storage stability at intervals of 1, 5, 10, 15, and 20 days. The results showed that pH increased significantly (p<0.001) with increasing amounts of added jujube powder. The pH also rose significantly with longer storage, but tended to decrease after 20 days. Acidity was reduced during the storage period. Viscosity was highest with 1% added jujube powder (p<0.001) on day 5 of storage (p<0.001). The L color value decreased as the amount of added jujube powder increased, whereas the a-value (redness) and b-value (yellowness) increased (p<0.001). In an sensory test, color in samples with 0, 1, and 2% jujube powder exhibited the highest values (p<0.01), but no significant differences in flavor or texture were observed. Sweetness and sourness were highest in the yogurt with 3% jujube powder (p<0.05). Overall quality tended to be higher for yogurt with 3% jujube powder, but the difference was in significant. Taken together, our results indicate that yogurt with 3% jujube powder may the most suitable for manufacturing purposes.

  • This study investigated the quality characteristics and antioxidant activities of wet noodles as well as their cooking properties following the addition of peanut sprout extract (PSE) and powder (PSP), which are known to contain a significant level of resveratrol. Wet noodles were prepared with 0, 2.5, 5, 7.5 and 10% PSE and PSP. Quality characteristics such as increasing volume of noodle, water ratio, turbidity of cooking water and color, texture, and sensory evaluation were then assessed. Additionally, the total resveratrol content in the cooked noodles was analyzed by HPLC and DPPH free radical scavenging capacity. As the amount of PSE and PSP increased, the L value of wet and cooked noodles significantly decreased, whereas the a and b values increased (p<0.001). The L value of cooked noodles was significantly lower compared to wet noodles (p<0.001) whereas the a and b values were higher. For the cutting intensity properties of the cooked noodles, hardness was reduced with increasing amounts of PSE (p<0.001), and was significantly increased in proportion to the amount of PSP (p<0.05). Meanwhile, springiness was not significantly different in all groups. Total resveratrol content and free radical scavenging activity significantly increased in proportion to the amounts of PSE and PSP (p<0.001), especially in noodles containing 5%, 7.5% and 10% PSE and PSP. Finally, sensory evaluation of PSE noodle revealed that color, flavour, taste were significantly decreased (p<0.05). But there was no difference in overall acceptance among cooked noodles with 2.5% to 5% PSE comparison to the control. Sensory characteristics in the PSP noodle showed similar results. In conclusion, these findings suggest that peanut sprout extract and powder could be potentially used as functional food ingredients. In addition, up to 5% PSE and PSP can be substituted for wheat flour.

  • Though traditional seasonings are widely used in many dishes, however, no attention has been paid to the investigation of their effects on quality characteristics of food products. The present investigation was undertaken to study the effects of incorporating several traditional seasonings including doenjang (fermented soybean paste), gochu-jang (red pepper paste), fresh medium-hot, and hot peppers, and fresh garlic on the lipid oxidation, cholesterol content and sensory characteristics of fermented sausages. Six fermented sausage treatments (5 with 1% (w/w) each test seasoning and 1 without added test seasoning (control) were prepared. The addition of seasonings generally had beneficial effects on the improvement of fermented sausage's quality however the effects differed depending on the each type of seasonings added. Significant lower pH values were found in all fermented sausages made with the seasonings while, lower levels of lipid oxidation were found in the treatments with hot peppers and garlic as compared with the control (p<0.05). The treatment with seasonings did not cause color or texture defects in the products whereas the sausages made with gochu-jang had significantly higher Commission International de $l^{\prime}Eclairagea^{\ast}$ (redness) value in comparison with the control. Noticeably, incorporating doenjang, medium-hot peppers, hot peppers and garlic resulted in reduction of 26.50, 32.54, 47.04, and 48.54 mg cholesterol/100 g samples, respectively (p<0.05). Higher scores for the sensory traits such as aroma, taste, color and acceptability were also given for the sausages made with seasonings. The current work demonstrates that the test seasonings represent potentially natural ingredients to be used for producing healthier fermented sausages.
