In this study, rice wine cakes (Jubak) was produced using with Astragali memvranaceus with excellent antioxidant and antidiabetic effects and produced. This Jubak was applied to improve the cookies of modern taste and well-being products. The cookies according to the different ratio (added 0-1.0%) of Astragali memvranaceus and investigated the physicochemical characteristics, sensory evaluation, DPPH free radical scavenging activities, polyphenol and flavonoid contents. There were little changes in pH and density. The hardness of all treated cookies increased with Astragali memvranaceus Jubak(AJ) containing of different moisture contents. In color, L and a values of most cases increased in most of the treatments, but b value was reduced. In the sensory evaluation, the flavor and total scores showed the highest in 0.5% AJ cookies. But the higher proportion of AJ cookies that had unique flavors and tastes, so the total acceptance score decreased. The polyphenol and flavonoid contents increased in the higher proportion of AJ. In DPPH free radical scavenging activities, the control (no Jubak added) was 44%, and containing of 1% AJ cookies showed 82%. In conclusion, our study suggests that 0.5% in addition of AJ increased positive attributes and functional to cookies.

This study was carried out to investigate the quality characteristics and storage of noodle with added flowering cherry fruit powder. Wet noodles were prepared at concentration of 1, 2, and 3% (w/w) of the fruit based on flour weight. Moisture content of the noodles with or without flowering cherry fruit powder was 33.09~33.50%. Ca, K and Mg contents of flowering cherry fruit noodle were increasing at increasing concentrations of flowering cherry fruit powder. Cooked weight, volume, and water absorption decreased with increased fruit powder, whereas turbidity increased. For Hunter's color values of noodles, L (lightness) and b (yellowness) values decreased with increasing concentration of flowering cherry fruit powder, whereas a (redness) value increased. For mechanical characteristics of the noodles, adhesiveness of cooked noodle with flowering cherry fruit powder were higher than those of control. The pH of flowering cherry fruit noodle was lower than that of control during storage. Bacterial counts of wet noodle with flowering cherry fruit powders were lower than those of the control on the 10th day of storage at
. From the sensory evaluation of 20's, texture, taste, and overall preference were not significantly different between the control and the fruit groups, but the color scores of 2% and 3% flowering cherry fruit noodle were significantly higher than that of 1% fruit noodle (p<0.05). In 40's sensory evaluation, color and overall preference scores of flowering cherry fruit noodle were significantly higher than those of control. In conclusion, the results of this study were suggested that the addition of flowering cherry fruit powder in combination with flour was tended to improve antimicrobial effects during storage when compared to control.

The effects of added brown rice flour on the quality characteristic of waffle were investigated. Waffle were prepared by the addition of 0%, 25%, 50%, 75% and 100% of brown rice flour on wheat flour. The weight of waffle with brown rice flour ranged from 103.0~107.0 g and that of the control was 100.0 g. The volume of the waffle prepared by adding brown rice flour were 225.0~303.0 mL and that of the control was 307.5 mL. The weight of the waffle increased with increasing brown rice flour concentration, whereas volume and baking loss decreased. The hardness, chewiness (p<0.05) and springiness decreased with the addition of brown rice flour. The Hunter L values of waffle decreased, whereas a and b values increased with the addition of brown rice flour. The result of the sensory evaluation showed that taste and overall acceptability (p<0.05) was the highest for added brown rice flour.

Lipid oxidation and antioxidants changes in perilla oil emulsion added with chlorophyll were studied during storage in the dark or under 1,700 lux light at
for 48 h. The emulsion was consisted of perilla oil (33.12 g), 5% acetic acid (66.23 g), egg yolk powder (0.5 g), and xanthan gum (0.15 g), and Chlorophyll b was added to the emulsion at 0, 2.5 and 4 mg/kg. The lipid oxidation was evaluated by headspace oxygen consumption and hydroperoxide formation, and tocopherols and polyphenols were monitored by HPLC and spectrophotometry at 725 nm, respectively. The lipid oxidation of the perilla oil emulsion in the dark was not significant regardless of the addition of chlorophyll. Light increased and accelerated the lipid oxidation of the emulsion, and increased addition level of chlorophyll under light increased it further. However, there was no significant change in fatty acid composition in any case. Contents of tocopherols and polyphenols in the emulsion were not significantly changed during storage in the dark regardless of chlorophyll addition, indicating their little degradation. Tocopherols and polyphenols in the emulsion were significantly degraded during storage of the emulsion under light, and the degradation rate of polyphenols was increased with addition level of chlorophyll. The lipid oxidation of the perilla oil emulsion was inversely related with the residual amounts of tocopherols and polyphenols, with more dependent on the retention of polyphenols than that of tocopherols.

The purpose of this study was to analyze the gap between importance and performance in perceived sanitation management for general hospital foodservice operations. Data were collected through surveys given to 168 hospital dietitians in the Seoul-Incheon, Gyeonggi-do, Daegu, and North Gyeongsang province. The 65 questionnaires from total questionnaires were usable and the response rate was 38.7%. All statistical analyses were conducted using the SPSS package program (version 20.0) for t-test, ANOVA, and importance-performance analysis (IPA). According to the importance and performance analysis for 26 items, the importance score was significantly higher than the performance score for 22 items. In addition, the results of IPA showed the following areas as improvement priorities: handling foods on working table and management of distribution temperature. In conclusion, the performance level of prerequisite programs applying to the hospital foodservice needs improvement, especially cross-contamination prevention and temperature control for distribution. Additionally dietitians should be educated about sanitation management items that perceived to be less important than the others.

The purpose of this study was to examine the level of importance of service quality provided by restaurant when industry meal service recipients used the restaurant. Additionally, the purpose was to compare the level of satisfaction on the respective service qualities of company cafeteria and outside restaurant. The level of relative importance and satisfaction of service quality attributes are comparatively analyzed using the Important-Performance Analysis (IPA) of customers in order to provide basic information on the direction of marketing to efficiently operate company foodservice facilities. Restaurant service qualities were divided into the six factors of hygiene, convenience, food, environment, subsidiary services and food distribution process. The results revealed that the 'environment' of both company cafeteria and outside restaurant was needed to improve as quickly as possible. Additionally, it was found that the level of satisfaction was higher in the 'food' and 'environment' factors when using company cafeteria and outside restaurants, which would become an important attribute for the company foodservice recipients to use outside restaurants than using company cafeteria. Accordingly, it could be said that company cafeteria will need further control of the 'food' and 'environment' factors.
