  • The purpose of this study was to investigate the practical application and optimum conditions for adding functional dropwort, which is rich in physiological activity to Sulgidduk, toward developing dropwort-added dduk as a healthy food. To this end, samples of Sulgidduk with 0, 1, 3, 5 and 7% added dropwort powder were prepared, stored for 2 days at $20^{\circ}C$, after which the water content, chromaticity, and mechanical and sensory quality characteristics were measured. The results were as follows. The water content of nonglutinous rice powder and dropwort powder used for dropwort-added Sulgidduk was 41.73% and 3.5%, respectively. The water content decreased with increasing amounts of dropwort powder the group with 7% added dropwort powder was 33.88%, the lowest. For chromaticity, the L value decreased with increasing amount of dropwort powder with significant differences between groups with different added amounts (p<0.001). The a and b values increased with increasing amount of dropwort powder while they were 7.21 and 29.22, respectively, in the 7% dropwort powder-added group with significant differences between samples (p<0.001). For mechanical quality characteristics hardness decreased with increasing of amount of dropwort powder with significant differences between samples (p<0.001). There was no difference between samples in cohesiveness and springiness. Gumminess increased with increasing amount of dropwort powder with significant differences between samples (p<0.05). Chewiness and adhesiveness had a tendency to decrease with increasing amounts of dropwort powder. Overall acceptability was in the order of 3%, 5%, 1%, 7%, and 0% dropwort powder-added groups. Overall, for dropwort powder added Sulgidduk, the quality of flavor, color and taste was acceptable, compared to other powder-added groups. The 3% dropwort powder-added group was highly rated in general preference making it most desirable for making dropwort powder-added Sulgidduk.

  • The aim of this study was to establish the superiority of ohmic heating over conventional heating for the sterilization of mulberry juice. Heat treatment of fresh juice significantly reduced the concentration of soluble solids, lowered the pH, and lowered the reducing sugar content (p<0.01). Color measurements showed decreases in the L and a values and increases in the b, H and C values after heat treatment, although the total color differences were smaller after ohmic heating than after conventional heating of fresh juice. The antioxidant capacities, such as reducing power, FRAP, and DPPH, decreased in the order of fresh juice, ohmically heated juice and conventionally heated juice. Furthermore, the anthocyanin, flovonoid, and total antioxidant capacities of the juices significantly decreased in the same order. Sensory evaluations showed no difference between fresh and ohmically heated mulberry fruit juice excluding off-flavor, whereas conventionally heated juice received significantly lower evaluations. The microbial counts were zero in the juice after either heat treatment. Thus, ohmic heat treatment can be effectively used to sterilize fresh mulberry juice to obtain good shelf life with minimal physicochemical, color, antioxidant and sensory deterioration.

  • Osteoporosis is recognized as one of the major hormonal deficiency diseases, especially in menopausal women and the elderly. When the estrogen level is reduced in the body, local factors, which are known to be related with bone resorption, are increased and promote osteoclastogenesis. In our previous study, we validated the estrogenicity of silkworm pupa. In this study, we investigated the effect of silkworm pupa extract (SPE) on the function of osteoblastic MC3T3-E1 cells. SPE (10 and $50\;{\mu}g/mL$) significantly elevated cell viability, alkaline phosphatase (ALP) activity, and collagen content in the cells. The effect of SPE ($50\;{\mu}g/mL$) in increasing cell viability, ALP activity, and collagen content was completely inhibited by the presence of $10^{-6}\;M$ of cycloheximide and $10^{-6}\;M$ of tamoxifen, suggesting that SPE's effect results from a newly synthesized, protein component and that it might be partly involved in estrogen action. Furthermore, we examined the effect of SPE on the $H_2O_2-induced$ apoptosis and production of local factors in osteoblasts. Treatment with SPE ($50\;{\mu}g/mL$) decreased the 0.2 mM $H_2O_2-induced$ apoptosis and the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and nitric oxide (NO) in osteoblasts. Our data indicate that the enhancement of osteoblast function by silkworm pupa may prevent osteoporosis and inflammatory bone diseases.

  • The purpose of this study was to investigate the product characteristics of 'Songhwasulgi,' which combines different kinds of pine pollen flours and sugars with non-glutinous, rich flour. The results of sensory evaluation indicated that the larger amount of pine pollen flour was mixed with non-glutinous rice flour higher level of bitterness, softness, and feeling after-swallowing was obtained degree of chewiness was in relation to the lesser amount of pine pollen flour. With regard to color, a higher acceptance level was achieved as the lesser amount of pine pollen flour was incorporated with non-glutinous rice How. On the other hand, it was revealed that the category of adding a honey to $7\%$ of pine pollen flour was found to be the highest level of flavor and overall quality According to the results of texture evaluation, the degree of hardness, adhesiveness, and cohesiveness decreased as the larger amount of pine pollen flour was combined with non-glutinous rice flour. It was also found that the springiness of the texture tended to be low as more pine pollen flour was added. In addition, the degrees of gumminess and chewiness was inversely related to the amount of pine pollen flour With respect to a correlation between sensory evaluation and mechanical test, it was found that Songhwasulgi with higher acceptance level for color and flavor also obtained a higher level of hardness and overall quality.

  • In this study, five different Gochujang (a traditional Korean sauce prepared using fermented red pepper paste) sauces were heated at $100^{\circ}C$ for 5 min using a continuous ohmic heating system. Ohmic heating yielded greater reduction in microbial counts (90-95% reduction) than did conventional heating (65-75% reduction). The sterilization effect of the continuous ohmic heater increased with increasing sample flow rate and decreasing Reynolds number inside the pipe. Low-viscosity samples had higher electrical conductivity and were better suited for ohmic heating than were high-viscosity samples. The color and texture were also satisfactorily maintained after ohmic heating. Compared with conventional heating, ohmic heating provided rapid and uniform heating, which is more suitable for aseptic thermal processing of viscous foods.

  • As Korea has approached the aging society, older Koreans have become an important force in restaurant sales today. To succeed with this silver market, it is important for restaurant managers to know who they are and what factors influence older Koreans' eating-out decision making process. The purpose of this study was to investigate the effect of the silver consumers' education level on eating-out decision making process. Data were collected from 178 older consumers above 55 years old and analyzed using the descriptive statistic analysis, MANOVA, and one-way ANOVA. The results showed that the elderly consumers' education level significantly influenced the decision making process in determining where to eat out. Significant differences were found in the Problem Recognition Step(Wilks' Lambda=0.817, F=2.991), Information Search Step(Wilks' Lambda=0828, F=2.218), Alternative Evaluation Step II(Wilks' Lambda=0.741, F=3.596), Purchase Decision Step(Wilks' Lambda=0.859, F=2.223), and the Post-Purchase Behavior(Wilks' Lambda=0.885, F=1.780). The higher education level was, the more directly involved in the eating out decision process. The elderly consumers with university education were likely to 'propose to eat out by themselves'(F=9.346), to obtain restaurant information from the 'printed materials'(F=7.452), to go to 'family restaurant'(F=9.057), 'Japanese restaurant'(F=8.7891) and 'fine dining restaurants'(F=3.936), and to directly express their emotion when they had complaints about restaurant service(F=3.206). In conclusion, older Koreans will become more healthy and wealthy which means the dining out activity will be an important part of their life to socialize with people. Therefore, food service operations should consider the elderly consumers' needs and expectation of restaurant services and actively position themselves for this new market segment.

  • The purpose of this study is to determine the optimal mix ratio of Maneul-Sulgi and thereby, review its availability as health cake. For this purpose, the ratios of garlic juice and powder were varied with sugar added. As a result of quantitative descriptive analysis, it was found that the more the garlic juice and powder were added to non-glutinous rice, the Garlic taste was stronger. On the other hand, the less garlic powder was added, the cake would taste softer, and the less garlic juice was added, the cake was more chewy and moist. The feeling after swallowing was best when the ratio of garlic juice was $7\%$. As a consequence of surveying the tastes of Maneul-Sulgi, it was found that the less garlic powder was added to non-glutinous rice, the cake was more preferred. It was perceived that the ratio of garlic juice should be $7\%$ for flavor and desirable taste. As a result of testing the mechanic characteristics, it was found that the less garlic juice was used, the cake was more hard, elastic, cohesive, viscose and chewy. The more garlic powder was used, the Adhesiveness was higher. The Overall acceptability of sensory examination for Garlic taste had positive correlation Hardness of sensory examination and mechanical examination for adhesiveness.

  • The fermentation of Panax ginseng yields many compounds including ginsenosides that have various biological functions. The objective of this study was to investigate the modulation of nitric oxide (NO), Interleukin (IL)-6 and tumor necrosis factor $(TNF)-{\alpha}$ in Raw 264.7 cells treated with ginseng fermented by Penibacillus MBT213. Nitric oxide production in the Raw 264.7 cells treated for 24 hours with fermented ginseng at 3, 7, and 14 days after the treatment decreased to 74, 43, and 36%, respectively, compared with the positive control. The production of IL-6 was inhibited in all the cells treated with fermented ginseng at 3, 7, and 14 days after the treatment except for the positive control. The $TNF-{\alpha}$ production in the Raw 264.7 cells treated with fermented ginseng for 6 hours at 3, 7, and 14 days after the treatment was about 40,000, 85,000 and 65,000 pg/mL, respectively. Moreover, the $TNF-{\alpha}$ production in the Raw 264.7 cells treated with fermented ginseng for 24 hours at 7 and 14 days after the treatment was about 160,000 and 180,000 pg/mL, respectively. However, $TNF-{\alpha}$ production was inhibited in the Raw 264.7 cells at 6 and 12 hours after the treatment with fermented ginseng. herefore, it was confirmed that the immunological activity of the Raw 264.7 macrophages was affected by the treatment with fermented ginseng. It was concluded that ginseng fermented by Paenibacillus MBT213 possesses a potential anti-inflammatory activity and could be used as an ingredient in functional foods and pharmaceutical products.
