Foxtail millet (Setaria italica L. Beaur) is a native Korean herbal medical food and a native millet, and Koreans have eaten it as a substitute for rice since ancient times. Foods using foxtail millet (Setaria italica L. Beaur) have been recorded not only in cookbooks but also in Korean traditional medical books several times. Therefore, the purposes of this study was to investigate Food-Therapy (食治) using foxtail millet (Setaria italica L. Beaur) recorded in the literature from 1300 to 1600 from early to mid-Joseon (朝鮮) and provide data required to develop menus for Yaksun (藥膳, herbal food). This study examined Food-Therapy using foxtail millet (Setaria italica L. Beaur) in 10 types of literatures from the 1300s to the 1600s. and is described in the literature a total of 63 times. According to classification by cooking method, porridge (粥) was most frequently mentioned in the literature at 27 times. The cooking method of Soup (湯) is described 11 times. Cooking methods such as porridge juice and soup are frequently used since those methods are digestive and absorptive. Other food ingredients described using foxtail millet (Setaria italica L. Beaur) are white leek (Allii Fistulosi Bulbus) ginger (Zingiber officinale), chicken egg, Allium chinense, sparrow (Passer montanus), rooster liver, Du-si, crucian carp (Carassius auratus L), and white broiler. Other medicinal herbs described with Setaria italica are Panax ginseng (人蔘), Poria cocos (茯笭), Angelica acutiloba (當歸), Ziziphus jujuba (大棗), Liriopeplatyphylla (麥門冬), and cinnamon (肉桂). Food-Therapy using Setaria italica L. Beauv was described as a prescription for stomach and spleen (脾胃), stomach reflux (反胃), defecation and urinary disorder (大小便難), cholera, deficiency syndrome (虛症), and tonification (補益). This focus on promoting health and preventing diseases by strengthening the stomach and spleen and improving defecation and urination using Food-Therapy when herbal medicine was rare.

${\beta}-Carotene$, vitamin E, and folate contents according to color and species of Capsicum annuum were investigated. In addition, four C. annuum species were cooked by using different methods (boiling, pan-cooking, pan-frying, deep-frying, steaming, roasting, and microwaving), and retention rates of ${\beta}-Carotene$, vitamin E, and folate affected by color and species were evaluated. Weight loss was observed in all paprika and pepper species using all cooking methods. ${\beta}-Carotene$ and folate contents of C. annuum samples were significantly different by color, species, and cooking method (P<0.05), whereas vitamin E contents were not significantly affected by species. ${\beta}-Carotene$, vitamin E, and folate contents (mg/100 g) of raw C. annuum showed ranges of 95.4 (green pepper)~2,441.1 (red pepper), 0.7 (green paprika)~4.2 (red paprika), and 6.2 (green pepper)~148.7 (red pepper). As a result, the highest ${\beta}-Carotene$, vitamin E, and folate contents were detected in deep fried red pepper, roasted red pepper, and boiled red pepper, respectively, among the cooked samples. Retention rates of C. annuum varied by cooking method, resulting in ranges of 77.3% (boiled red pepper)~356.4% (roasted green pepper) for ${\beta}-Carotene$, 2.0% (microwaved red pepper)~789.3% (deep-fried green paprika) for vitamin E, and 20.9% (microwaved red pepper)~445.1% (steamed green pepper) for folate. Over 75% retention rates were observed for ${\beta}-Carotene$, vitamin E, and folate in all samples except for red pepper. However, in red pepper, vitamin E and folate retentions were remarkably lowered by deep frying and micro-waving, resulting in rates of 2.0~32.1%. This study provides information on effective cooking methods for vitamin retention in C. annuum depending on color and species.

In this study, 0, 20, 40, 60, 80, and 100% $Ulmus$ $pumila$ L. nonglutinous and glutinous sikhe were added to $Ulmus$ $pumila$ L. extracts for 15 days at $4^{\circ}C$, and for seven days at $25^{\circ}C$, to examine the extracts' storage properties and sensory characteristics. The results are as follows: (1) On the changes of pH and acidity during storage of $Ulmus$ $pumila$ L. nonglutinous and glutinous sikhe, both of them showed lower pH values with lower additive $Ulmus$ $pumila$ L. extract contents. The pH value continuously decreased with a longer storage period, and the acidity was higher with a lower concentration of $Ulmus$ $pumila$ L. extract. (2) The total microbial cell count during storage of $Ulmus$ $pumila$ L. nonglutinous and glutinous sikhe at $4^{\circ}C$ was 4.6-5.0 log CFU/g at 0 day. The sikhe to which $Ulmus$ $pumila$ L. extract was not added increased to 8.8-9.0 log CFU/g on the seventh storage day, while the sikhye to which 80 and 100% $Ulmus$ $pumila$ L. extracts were added were 7.8 and 6.9 logCFU/g, respectively. Thus, the total cell count was lower with a higher additive content of $Ulmus$ $pumila$ L. extract. The total cell count of the sikhe to which 0-60% $Ulmus$ $pumila$ L. extracts reached the maximum value on the seventh storage day and did not show any change thereafter. The total cell count of the sikhe to which 80 and 100% $Ulmus$ $pumila$ L. extracts were added, however, reached the maximum value on the 10th to 13th storage days, thus showing that the storage period was increased by $Ulmus$ $pumila$ L. At $25^{\circ}C$, the total cell count was 4.6-5.0 log CFU/g on 0 day and continuously increased during the storage period. It had increased to 8.9-9.5 log CFU/g on the seventh storage day, and no differences were shown according to the additive content of $Ulmus$ $pumila$ L. extract. (3) On the sensory characteristics of $Ulmus$ $pumila$ L. nonglutinous and glutinous sikhe, the $Ulmus$ $pumila$ L. nonglutinous sikhe to which 20% $Ulmus$ $pumila$ L. extract was added showed the highest overall-acceptability value ($4.23{\pm}0.95$), whereas the $Ulmus$ $pumila$ L. glutinous sikhe to which 40% $Ulmus$ $pumila$ L. extract was added showed the highest overall-acceptability value ($3.95{\pm}0.95$). The sikhe to which 20 and 40% $Ulmus$ $pumila$ L. extracts were added showed significantly high taste, flavor, sweetness, and overall-preference values (p<0.05).

Effects of extraction methods on reducing concentrations of pro-oxidants (total iron and protein) of salmon was determined. For development of the extraction process, the effectiveness of several extraction methods was determined and compared, including heat treatment (60, 80, and $100^{\circ}C$), ion exchange and carboxymethyl (CM)-cellulose column chromatography, and ultrafiltration (UF). Protein, total iron, and anserine contents of salmon extracts were 23.64 mg/mL, $16.20{\mu}g/mL$, and 5.47 mg/mL in non-heated extracts, 7.40 mg/mL, $2.32{\mu}g/mL$, and 5.20 mg/mL in heated extracts at $60^{\circ}C$, 7.64 mg/mL, $1.20{\mu}g/mL$, and 5.21 mg/mL at $80^{\circ}C$, and 7.04 mg/mL, $0.68{\mu}g/mL$, and 4.04 mg/mL at $100^{\circ}C$, respectively. Heating and UF decreased contents of protein and total iron, whereas only UF slightly decreased anserine content. Application of the primary ion exchange method increased the content of anserine up to 16%. Protein and total iron contents by the primary ion exchange method decreased by 70 and 98%, respectively. Secondary ion exchange (CM-cellulose) treatment after primary ion exchange and UF resulted in lower anserine content than the primary ion exchange method. However, the content of impurities (protein, total iron) was lower than in all other salmon extracts. Therefore, primary ion exchange, UF, and secondary ion exchange method were the best extraction processes in this study.

The purpose of this study was to analyze the importance and performance of sanitation management within childcare center foodservice facilities in Gyeongbuk province. The survey involved 248 people who participated in the food hygiene and safety education for childcare center managers in Gyeongbuk province from June to July 2010. A total of 236 survey papers were analyzed statistically by SPSS program. By the method, t-test and importance-performance analysis (IPA) was performed. Among the respondents, facility managers are 40s (41.9%) which accounted the most percentage, and for the type of facility, the largest amount was home (39.9%). The number of preschool children who are under 20 people accounted for 45.3% and food service staffs were accounted for 36.7%. No significant differences were observed for the four items on the IPA, except for the topics "the immediate deal with trash and leftover food" and "minimizing time (within 2 hours) for distribution after cooking" (p<0.001). The average score on the IPA was 4.14 points, and the average score for the importance of the evaluation was 4.49 points out of 5. Finally, childcare facility managers are aware of the importance that is lower than can be done. The results suggest that continuing education is necessary to administrators to manage the health care facility effectively.

Ulmus pumila L. bark underwent distilled water extraction under three temperature condition ($4^{\circ}C$, room temperature, or $80^{\circ}C$) and two extraction times (1, or 5 min) in order to develop a functional beverage products. Changes in yield, pH, color, total phenolic (TP) content, tannin content and antioxidant activity of the aqueous extracts were evaluated for each extraction temperature and duration. Extraction conditions did not affect yield or pH value of the extracts; however CIE $b^*$ values were high in extracts prepared under high extraction temperature ($80^{\circ}C$) and long extraction duration (5 min) conditions. Both extraction temperature and duration affected the TP and tannin contents of the extracts; however, all extraction conditions resulted in ${\geq}450\;mg\;GAE/g$ TP content and ${\geq}80\;mg\;CE/g$ tannin content. All extracts exhibited ABTS and DPPH radical scavenging ability similar to that of vitamin C. Nitric oxide inhibition activity was lower in the 5 min duration sample than in the 1 min sample. The $4^{\circ}C$ extraction temperature produced an extract with the highest reducing power and hydrogen peroxide values. Extraction temperature also affected sensory evaluation results with the $80^{\circ}C$ extraction temperature producing significantly higher flavor, bitterness, and color score, than those obtained under $4^{\circ}C$ and room temperature extraction conditions.

The purpose of this study is to examine the difference of Chinese consumer preference between chicken burgers cooked by Sous-vide adding Korean-styled seasoning and chicken burgers from local fast food restaurants. For Chinese women in their 20s who reside in Beijing, China, the most important attribute for eating-out was taste (M=6.5), health (M=6.0) and pleasure (M=5.6) in order and 68.60% of them replied that they were interested in Korean cuisine. More than 90% answered they like Korean food for its good taste, shape and color. As for burger preference, BB was significantly higher in terms of the overall and appearance preference. However, there was no significant difference between AB and SB. As for flavor and texture, it showed no significant differences among BB, AB, and SB products. For SB, total balance, soft texture of patty and balance of flavor characteristics were the reasons for their preference of the burger.

Fatty acid composition, protein content, and shape change of Listeria monocytogenes treated with ethanol extracts from Schizandra chinensis were examined. Transmission electron micrography of cells treated with ethanolic S. chinensis extracts showed development of morphological changes. Cell surfaces were irregular, swollen, or even disrupted after treatment with ethanol extracts, compared with the smooth surfaces of normal cells. Interestingly, cell protein content was decreased by ethanol extract treatment. Cell fatty acid composition was also changed after treatment with ethanol extracts. The levels of 13-methylpentadecanoic acid (i-15:0), 12-methylpentadecanoic acid (a-15:0) and 15-methylpentadecanoic acid (i-17:0) of L. monocytogenes Scott A and L. monocytogenes ATCC 19111 were decreased, but the concentrations of Cis-9,12 octadecanoic acid ($18:2^{9,12}$) and cis-9-octadecanoic acid ($18:1^9$) were increased. 13-methylpentadecanoic acid (i-15:0) and 12-methylpentadecanoic acid (a-15:0) levels in L. monocytogenes Brie I were decreased but the concentrations of Cis-9,12 octadecanoic acid ($18:2^{9,12}$) and cis-9-octadecanoic acid ($18:1^9$) were increased after treatment with ethanolic extracts. Notably, the levels of 12-methylpentadecanoic acid (a-15:0) significantly were decreased but those of cis-9,12 octadecanoic acid ($18:2^{9,12}$) significantly were increased in all tested microorganisms.
