  • The aim of this study was to use purple sweet potato powder to develop a recipe for a nutritional cookie with an optimal composition of ingredients and texture, in order to acquire strong preference responses by all age groups in sensory tests. Wheat flour was partially substituted with purple sweet potato powder to reduce the wheat flour content of the cookies. Measurements were made and analyzed according to the Response Surface Methodology technique, which showed 16 experimental points including 3 replicates for the purple sweet potato powder, sugar, and butter. The compositional and functional properties of the sample were measured, and the values obtained were applied to a mathematical model. A canonical form and perturbation plot showed the influence of each ingredient on the final product mixture. The results of sensory evaluations showed very significant values for flavor (P<0.0071), texture (P<0.0306), taste (P<0.0190), and overall quality (P<0.0142). Instrumental analysis showed significant values for hardness (P<0.0027), yellowness (P<0.0061) and spread ratio (P<0.0001). The optimal compositional ratios were determined to be 21.75 g for the purple sweet potato powder, 37.05 g for the sugar, and 60.59 g for the butter.

  • In order to standardize a recipe of Jeung-Pyun, fermented rice cake, we studied the sensory, rheological and physicochemical characteristics of Jeung-Pyun in terms of fermentation time and ratio of ingredients. Jeung-Pyun fermented for 3 hours was higher in pH, better in taste, hardness and overall quality than that fermented for 7 hours. It was softer, and had more moisture and fine grain as the amount of added water increased. Jeung-Pyun made with 80% added water had the greatest volume. Jeung-Pyun without salt was the worst in color and flavor and the smallest in volume. As the Jeung-Pyun was added more sugar and Tak-Ju, the volume was more larger and the moisture was more less. Taste and overall quality of Jeurig-Pyun was not affected by the amount of Tak-Ju added. The pH of Jeung-Pyun was lower as it was added more Tak-Ju. Therefore, Jeung-Pyun which is fermented for 3 hours, with 70% water, 0.8% salt, 15% sugar, and 30% Tak-ju was the most acceptable one in terms of sensory qualities and physiochemical properties.

  • This study sought to identify unique semiotic codes of Korean cuisine, including table settings, service styles, service ware selection, cooking techniques, and the logic behind menu composition. This research also aimed to verify that yangnyomjang reflects the code of Korean food culture. One of key findings from this study was that hidden codes of Korean food were found in their daily set-up for bapsang (dining table), which was found to decodify polysemic characteristics with an emphasis on harmony. These semiotic codes were influenced by the yin and yang philosophy and impact dining activities in our daily lives. Korean bapsang, composed of bap (rice), guk (soup) and banchan (side dishes), helps every individual diner share the semiotic codes of Korean cuisine within the context of paradigm and syntagm. Yangnyomjang, a major component of the Korean menu, also represents a unique code of Korean cuisine in its structure, main ingredients, production, and usage. This study also mathematically verified that a synchronic table setting of Korean cuisine provides diners with more opportunities for potential flavor combinations, compared to the Western service setting.

  • Objectives of this study were to investigate the acceptability of liver sausages, one of the most favorite product of meats, and to examine the applicability of pork liver in manufacturing sausages. Sausages containing different proportions of pork liver were manufactured with various processes and were tested and analysed by means of sensory evaluation. Based on th basic recipe for manufacturing sausages, fifteen recipies were proposed with different combinations of ingredients, followed by evaluations on their physicochemical and nutritional properties. Sausages manufactured with different methods (sliceable, spreadable, smoked spreadable) and different proportions of liver were also evaluated. The Findings from these experiments are summarized as follows: 1. As the percentage of the liver was increased, outer color of experimental sausages were significantly decreased. 2. The hardness, gumminess, chewiness were significantly decreased as the amount of liver increased. 3. Sausages containing 30% pork liver had best acceptability after swallowing. 4. The flavor and taste of liver in experimental sausages were significantly increased by adding liver. In summary, sausages containing 30% pork liver had best acceptability for consumption in terms of the indices measured in this study.

  • This study was designed to investigate the possible utilization of Ligularia stenocephala as a source of functional ingredients in white bread. In terms of color values, as more Ligularia stenocephala leaf powder was added, 'lightness,' 'redness,' and 'yellowness' decreased in the crust, while in the bread crumb 'lightness' and 'yellowness' decreased, but 'redness' increased. When 5.0%, 7.5%, or 10.0% Ligularia stenocephala leaf powder was substituted for an equivalent amount of strong flour, the ratio of the volume and specific volume of white bread decreased while its weight increased. In the texture measurements for the white breads, the hardness decreased slightly with the addition of 2.5% Ligularia stenocephala leaf powder, but increased with the addition of 5.0%, 7.5%, or 10.0% Ligularia stenocephala leaf powder. The addition of the Ligularia stenocephala leaf powder also increased the springiness and gumminess of the white bread. The highest sensory scores for color, flavor, taste, texture, and overall acceptance for both the student group and the baker group were obtained from white bread with 5.0% Ligularia stenocephala leaf powder. The highest sensory scores for the housewife group for taste, texture, and overall acceptance were obtained from control bread. Through the results of these experiments, we conclude that the highest quantity of Ligularia stenocephala leaf powder content should be no more than 5.0% when making bread with added Ligularia stenocephala leaf powder.

  • Omega-3 rich fish oils are extremely labile, thus requiring control of oxidation and off flavor development. A recently proposed emulsification method, layer-by-layer (LbL) deposition, was found to be a plausible method to enhance the characteristics of bioactive ingredients, especially lipids. The present work was designed to test the possibility of enhancing the uptake and utilization of omega-3 fatty acids present in fish oil. The bioavailability of nano-emulsified fish oil was monitored in terms of intestinal absorption as well as skin permeability by using the everted intestinal sac model and Franz cell model. The skin permeability and intestinal absorption characteristics was significantly improved by LbL emulsification with lecithin/chitosan/low methoxypectin. Multilayer encapsulation along with nano-emulsification can be a useful method to deliver biologically active lipids and related components, such as fish oil. The protective effect of this tool from lipid oxidation still needs to be verified.

  • This study aimed to find oils that can replace high-priced sesame oil. The quality of baked Yackwa containing different types of oils (rice bran, olive, or sesame oils) and amount of oils (30, 35, 40%) were investigated. The hardness of the baked Yackwa depended on the amount of oil, as more oil led to a softer texture of baked Yackwa. According to sensory evaluations, baked Yackwa with rice bran oil received the highest score in taste quality, with sesame oil receiving the second highest score. The flavor of baked Yackwa containing the rice bran oil was also better than other samples. In contrast, there were no significant differences in taste between other samples, including baked Yackwa containing all ingredients, 40% sesame oil, and 40% olive oil. The overall acceptance showed the highest score in baked Yackwa with rice bran oil (35%). In conclusion, rice bran oil (35%) is recommended as an oil ingredient for baked Yackwa.
