  • The quality characteristics of pork patty prepared with chitosan containing preservatives during storage at $4^{\circ}C$ were investigated to improve its functional property and shelf life using food preservatives of natural origin (PI; 0.1% chitosan, 2.5% citric acid, 100 ppm grapefruit seed extract, 0.2% adipic acid, 0.1% Cinnamomum extract, D.W. 97.09% and PII; 0.1% chitosan, 2.5% citric acid, 100 ppm grapefruit seed extract, 0.2% adipic acid, 0.1% Lysimachia christinae Hance extract, D.W. 97.09%). The sensory qualities (taste, appearance, texture and overall acceptability) of patties preserved with PI (1, 3 and 5%) and PII (1, 3 and 5%) were also investigated. The taste and overall acceptability of patties prepared with 1% PI and 1% PII were higher than those of the control. The DPPH radical scavenging activities of the control, 1% PI and 1% PII treated patties were 13.54%, 21.78% and 14.07%, respectively. The total aerobes and coliform count of patties preserved with 1% PI were $10^4$ CFU/g and $10^2$ CFU/g, respectively, after 10 days storage at $4^{\circ}C$. Cooking loss from 1% PI and 1% PII treated patties was lower than that of from the control. Water holding capacity was the highest for 1% PI (65.84%), followed by 1% PII and then the control. The shelf life of patties prepared with 1% PI and 1% PII was extended by about 5 days relative to the control at $4^{\circ}C$.

  • The objective of this research was to study the effect of different frying temperatures and time conditions on acrylamide formation, crispness, and sensory evaluations of french fries. Acrylamide concentration in french fries increased as frying temperature and cooking time increased. The french fries treated at $165^{\circ}C$ frying had higher crispness values than those with other treatments. Frying treatments for 2 min 30 sec had the highest crispness values of the french fries. Sensory evaluations in terms of color, texture, and overall acceptability, showed the better quality of french fries treated at the frying condition of $165^{\circ}C$ and 2 min 30 sec than with other treatments. French fries cooked at $165^{\circ}C$ for 2 min 30 sec had not only good sensory properties in french fries, but also led to a reduction in acrylamide formation.

  • This study was conducted to evaluate the physicochemical and sensory characteristics of chiffon cakes made with rice flour ranging from 20-100% in place of wheat flour. The water binding capacity of the rice flour was greater than that of the wheat flour and its fat binding capacity was lower than that of the wheat flour. The batter stability data indicated that the 100% treatment was better than the control, and specific gravity values and specific loaf volumes were lower in the samples with added rice flour. Texture analysis found no significant differences in hardness, adhesiveness, cohesiveness, gumminess, and chewiness between the control and the 100% treatment. In the case of crust color, the rice flour-added chiffon cakes did not show any significant differences for their 'a' values. In addition, their crumb color was not significantly different in terms of both their 'L' and 'a' values. According to the sensory evaluation, there was no significant difference in overall acceptability between the control and the rice flour-added chiffon cakes. The highest sensory scores were obtained by the 100% treatment for overall acceptance and moistness. However, flavor, cohesiveness, and brittleness were not significantly different. These study results show that wheat flour could be replaced by rice flour up to 100% in chiffon cake.

  • The purpose of this study was to investigate the physicochemical and pasting properties of long-term stored domestic and imported rice supplied for food processing from government-controlled public rice stocks. Goamibyeo, which was bred for processing and harvested in 2011, was selected as the control rice for comparison. Rice was dry-milled, and the amylose contents of stored rice were 12~13%. Stored rice kernels were significantly harder than those of control, whereas damaged starch content and water absorption of flour were not significantly different from those of control. Overall, long-term stored domestic and imported rice showed high peak viscosities along with high viscosities of both hot and cold pastes. Both imported and domestic rice demonstrated insufficient properties for making 100% flat rice noodles or bread. They showed the greatest shrinkage during cooling after baking. Although their levels of cooking loss were less than that of control, stored rice showed a less elastic and softer cooked noodle texture compared to control flour.

  • This study was performed to reduce unpleasant taste and flavor of $Gastrodia$ $elata$ Blume as well as to improve utilization as functional food materials using fermentation. The component, antioxidant activity, and taste test were compared between fresh and fermented $Gastrodia$ $elata$ Blume powder (FGP). FGP contained higher level of total fat, protein, mineral, and fiber than raw material. The pH of FGP was higher compared to raw $Gastrodia$ $elata$ Blume powder (RGP), and antioxidant activity was as high as vitamin C regardless material status (raw vs. fermented). This result indicated that its activity was not decreased by fermentation. Dispersiveness and solubility of $Gastrodia$ $elata$ Blume powder was the best in 60-70 mesh. For sensory evaluation, FGP or RGP was mixed with either orange juice or yoghurt. The results showed that overall preference, taste, flavor, texture, and color were better in fermented $Gastrodia$ $elata$ Blume drinks than in raw ones. It is plausible that unpleasant taste and flavor of $Gastrodia$ $elata$ Blume was declined by fermentation. Thus, fermentation can be easily applied to eliminate unpleasant smell in $Gastrodia$ $elata$ Blume, and FGP can be mixed with other beverages to produce healthy food and drinks.

  • This study was performed to characterize the mechanism of the acceleration of lactic acid fermentation in milk incubated with potato flour irradiated by ${\gamma}$-ray and two types of lactobacillus, Lactobacillus bulgaricus and Streptococcus thermophillus, and to examine its effect on the quality of yogurt by assessing the acidity of lactic acid, viscosity, free amino acid, and sensory. In lactic acid fermented in the presence of 0.5% (w/w) potato flour, its acidity was higher, its pH was lower, and its viscosity was increased than lactic acid fermented in the absence of potato flour. In the sample fermented with the mixture of S. thermophillus and L. bulgaricus, the acid production rate was highest. In the samples fermented with a single type of bacteria, the acid production rate of S. thermophillus was higher than that the L. bulgaricus. Fermented a single type of bacteria with potato flour, the lysine utilization rate of L. bulgaricus and S. thermophillus was high. L. bulgaricus produced a large quantity of glutamic acid whereas S. thermophillus consumed glutamic acid. In sensory evaluation of yogurt fermented with potato flour, the preference of texture was improved while its color, taste, flavor, and overall preference were decreased. The data suggest that L. bulgaricus stimulates the growth of S. thermophillus by providing free glutamic acid that is required by S. thermophillus and thus the addition of potato flour shortens the fermentation period of yogurt.

  • The objectives of this study were to investigate the soaking properties of the high-dietary fiber rice 'Goami 2'and to develop korean white Gruel prepared with Goami 2. With increasing soaking time at room temperature ($20^{\circ}C$), the water absorbing character of Goami 2 and Ilpum significantly increased during the first hour of soaking time, after which it remained constant. On the contrary, the hardness of Goami 2 and Ilpum significantly decreased with increasing soaking time until one hour, after which it remained constant. The properties of Korean white gruel were evaluated using two varieties of rice (Goami 2, Ilpum) and three blending times (10, 20 and 30 seconds respectively). The rice flour of Goami 2 for Korean white gruel showed a greater number of small particles (<20 $\mu$m) than that of Ilpum. Hunter a'and b'values of Korean white gruel prepared with Goami 2 were higher than that of Korean white gruel prepared with Ilpum. The consistency values on Bostwick consistometer of Korean white gruel prepared with Goami 2 were higher than those of Korean white gruel prepared with Ilpum. The texture of Korean white gruel was examined using a back extrusion rig. All of the rheological parameters of Korean white gruel prepared with Goami 2 were decreased with increasing blending time, while in llpum they were increased. In the sensory evaluation results, the overall acceptability of korean white gruel prepared with Goami 2 blended for 20sec showed the highest sensory scores and desirability.

  • The Beijing Opera is one of the leading representatives of Chinese culture, which includes literature, music, dance, martial arts, and a type of performance that stems from the Chinese cultural history that is still relevant today. The purpose of this study is to develop fashion-cultural products from the Lian Pu of the Beijing Opera, a Chinese cultural tradition that receives abundant positive feedback from around the world, showing its value in both academic and practical fields. This study was carried out first as a theoretical study of the literature, definition and types of facial make up used in the Opera, as a way of examining the formative aspect. Secondly, an analysis was conducted on the main characters, 'Guan Yu' and 'Zhang Fei' of "The Romance of the Three Kingdoms", 'Li Kiu' and 'Lu Zhishen' of "All Men are Brothers" and 'Monkey King' of "Journey to West", employing the collection belonging to 'Yongqi Zhao' who is an expert on the Chinese Beijing Opera. Thirdly, two concepts were categorized, based on the analytic results of the abovementioned characters, each of which were then further categorized into three sub concepts. In regard to cultural development designs, the results of an analysis on the facial make-up color, form, and texture of the four main characters were utilized to construct the themes, "Modern Chic" and "Traditional Splendor". The simplest form that has been represented in the four figures has been applied to "Modern Chic" to show a modern image in which black, white and light blue has been used alongside the vivid red, which is a Chinese favorite, to highlight the characters. In "Traditional Splendor", which is focused on the stage art of the Opera, we see more artistic traditions and colors, to further appeal to our emotions. Traditional motifs have been applied using traditional Chinese arts, in order to develop strong and brilliant colors. The two styles of cultural products were developed in the form of women's scarves and men's ties; a total of 24 designs were expressed, using Illustrator CS6. In the final step, 4 scarves and 6 ties were produced as a sample, using high quality silk. The development of these cultural fashion products will bring an opportunity to show how Chinese traditional culture can be widely utilized in commercial market design.

  • Since the Korean apple industry needs to expand its export market in Southeast Asia, this study investigates the attributes of Korean apples affecting consumer preference in Indonesia, Malaysia, Singapore, and Thailand. Based on an Importance-Preference analysis, the results are summarized as follows. First, price is the most important determinant for purchasing Korean apples by Southeast Asian consumers, except in Malaysia. Second, managing the intrinsic(sweetness and chewing texture) and extrinsic(surface and color) factors needs to be well maintained. Third, the priority of the marketing factor(wrapping) should be lowered. Fourth, while the importance of extrinsic factors(shape and size) is low, satisfaction is high, so these factors need to be managed to avoid overkill. Overall, Korean apples should have their own merits with an appropriate proper price, while maintaining a high quality. The results of this paper may provide suitable strategies for promoting apple exports to Southeast Asia.
