  • This study was performed to make new products rising Pimpinella brachycarpa N., one of the Korean aromatic medicinal plant called chamnamul, which is a perennial plant of the Umbelliferae family. New products were natural chamnamul spice, chamnamul soup, chamnamul tea, and chamnamul mook as functional foods. The masking effect of Pimpinella brachvcarpa N., on fishy and meaty odor were investigated to test the usefulness of chamnamul as a natural spice. It could be concluded that the effect of added amounts of chamnamul on the cream soup increases the taste and appearance, and improves the flavor and color by the sensory evaluation. The chamnamul tea prepared by a filtration method is better than that by a leaching method on the preference test. In the texture properties of chamnamul mooks by a texture analyzer (XT-RA, Texturometer), the cohessiveness of them was higher than that of the white one.

  • The purpose of this study was to investigate the eating behavior and food preference of preschool children in day care facilities. Subjects of this study were 192 young children who lived in Sungnam city, Gyeonggi-Do. The results are summarized as follows: The parents reported that 34% of the children ate 'unbalanced diet'. And 16% of the children ate small portions of food. The parents picked up several reasons for their children's 'unbalanced diet' such as 'dislike of the tastes(29.2%), 'texture in the mouth(28.6%)', 'smell of food(18.2%)' Fifty-six percent of parents took 'to change the cooking methods' as the best way to make their children have good eating habits in their home. The highest score of preference among the children was noodles with bean sauce and kimbab for staple food, stews seaweed soup for soups and stews, bulgogi and fried chicken for side dish. The young children's preference score fur side dish made with meats were higher than made with vegetables. This study made a suggestion to parents of children ages 4 to 6 and to teachers in preschool that they prepare for foods made with vegetables.

  • This study analyzed the quality characteristics of nutritional bars with varying concentrations (0, 0.5, 1.5, 2.5%) of Enteromorpha intenstinalis powder added. To achieve this, color analysis, an assessment of DPPH radical scavenging activities, and sensory evaluations were performed. The results revealed that as the amount of Enteromorpha intestinalis powder (EIP) increased, pH and lightness values decreased. DPPH radical scavenging activities of 75.26%, 56.11%, 71.59%, and 62.49% were exhibited for the 0%, 0.5%, 1.5%, and 2.5% concentrations, respectively at 50 mg/mL. Significant differences were observed between the samples with respect to the color, appearance, texture, taste, and overall preference for the nutritional bars. Overall preference was highest for the nutritional bar with 1.5% Enteromorpha intenstinalis powder added. Therefore, adding 1.5% of Enteromorpha intenstinalis powder to a nutritional bar is most suitable for enhancing preference and quality characteristics.

  • This study investigated the influence of incorporating chestnut inner shell powder (CISP) at varying levels (0%, 3%, 6%, 9%, and 12% w/w) on the quality, antioxidant potential, and consumer preference of garaetteok, a Korean rice cake. Findings revealed a decrease in moisture content and pH with increasing CISP content. Color analysis indicated a reduction in lightness (L) and yellowness (b) values, while redness (a) values increased. Textural properties displayed an increase in hardness, chewiness, and gumminess, but a decrease in springiness, adhesiveness, and cohesiveness with increasing CISP levels. Sensory evaluation for appearance, taste, flavor, texture, and overall preference revealed the sample containing 6% CISP to be the most favorable. Moreover, the antioxidant activity of the garaetteok exhibited a positive correlation with increasing CISP content. In conclusion, incorporating 6% CISP resulted in improved quality characteristics for garaetteok development, offering enhanced nutritional value, antioxidant properties, and overall consumer preference.

  • Changes in the Qualify Properties of Doenjang Prepared using the Powder or extracts of Paecilomyces japonica were investigated during fermentation at 20$^{\circ}C$. The moisture content was increased during fermentation but was not significantly different in all treatments. The pH of Doenjang with p. japonica was lower than the control group and decreased with the fermentation time. The amino nitrogen content increased gradually for up to 60 days and decreased slightly at 90 days. The L, a and b value decreased in proportion to the fermentation period and those of Doenjang with P. japonica powder were the lowest. From the results of the sensory evaluation, the color of the control group was similar to "yellow" but that of the Doenjang made from powder of P. japonica was close to "dark brown" and those of the Doenjang made from the P. japonica extract were darker than that of the control group. The texture was "glossy and smooth" in all cases and preference about the texture was high. The Doenjang with added P. japonica Powder had a saltier taste and the Doenjang with P. japonica Powder had the least sweet taste. In the flavor and overall Preference, the Doenjang with P. japonica powder was the lowest.

  • The objective of this study was to compare the quality characteristics of cultured and red sea bream. The color of dorsal muscle was different between wild and cultured red sea bream. Lipid content of the dorsal muscle was higher in cultured fish than in wild one. The contents of moisture and crude protein in cultured fish muscle were almost same as those of wild one. Sensory evaluation of raw fish meat showed that cultured fish had lower preference in appearance, taste and texture than wild one. Especially the texture of cultured raw fish meat had lower preference than wild meat. For cooked fish meat, cultured fish were harder and less juicy than wild fish. These textural differences between wild and cultured meats were confirmed by objective evaluation including the measurements of hardness, springiness, and cohesiveness. Light microscopic observation showed that cultured red sea bream had more lipid in the surface layer near epidermis than wild one. Also more lipid droplet between muscle fibers were observed in cultured red sea bream by SEM.

  • The effect of using Korean wheat flour versus Australian wheat flour on noodle quality as a result of differing physical and chemical properties of the flours was investigated. The results provided appropriate technical information for selection of wheat varieties to produce high quality Korean salted noodles. Noodle quality was quantified based on measurement of the appearance and texture of noodles. When consumer preference tests were conducted, a firmer and more elastic texture was preferred for Korean white salted noodles, however, when appearance was included in the consumer tests, noodles made with Australian wheat were favored over Korean wheats. Korean flour was found to produce firmer and more elastic noodles, whereas Australian flour produced brighter, creamier colored noodles. In flour quality tests, Korean flours were found to have a higher setback viscosity and lower swelling power than Australian flour. Additionally, Korean flours had higher water absorption values. Protein content of flour was an important parameter affecting the firmness of Korean noodles, whereas setback viscosity and swelling power were the major determinants of elasticity. Overall, the important parameters for determination of the quality of Korean salted noodles were high setback viscosity, low swelling power, and high protein content.

  • The goal of this study is to show that the investigate is preference of beetroot cookie is preferred by consumers and can help to replace calcium, which is depleted because of the stress. As the amount of beetroot powder is increased, pH value, spread factors, loss and leaving rates, and texture properties of cookies were decreased. As a result of the measuring of colorimetric characteristics, the values of "L", "a", "b" were all decreased as the amount of beetroot powder was increased. The cookies containing 30% of beetroot powder was estimated as the most suitable to eat because of the flavor, color, and taste of the beetroot. But cookies having 20% of beetroot powder were estimated as the best to eat because of the texture, sticking power, hardness, and general preference. According to the results, the cookies containing 20% of beetroot powder were selected as the most suitable cookies to eat.

  • This study was conducted to investigate the effects of acorn ($Quercus$ autissima carruther) powder on the antioxidant activity and quality characteristics of cookies. Cookies were prepared with different amounts of acorn powder (at ratios of 0, 0.5, 1, 3 and 5% to total flour quantity). Antioxidant activity was estimated based on DPPH free radical scavenging activity and total phenol content in acorn powder and cookies. To analyze quality characteristics, bulk density, pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations were measured. Loss rate, a values, total polyphenol contents and DPPH free radical scavenging activity of cookies significantly increased with increasing acorn powder content (p<0.01), whereas pH of the dough, L values and b values of the cookies significantly decreased with increasing acorn powder content (p<0.01). The results of sensory evaluation (appearance, taste, flavor, texture and overall preference) demonstrate that the 3% acorn cookie group showed the highest degree of preference among all items of added acorn powder. From these results, we suggest that acorn is a good ingredient for increasing the consumer acceptability and functionality of cookies.
