The purpose of this study was to compare the status of sanitation education and sanitation knowledge in school foodservice with commercial foodservice. The survey sample was institutional foodservice directors (n = 88) in A office of education and commercial foodservice directors (n = 81) in B foodservice industry. The questionnaire requested information about demographic information, situation of sanitation education, contents of sanitation education practice, importance of sanitation education, and sanitation knowledge. Data were analyzed using frequencies, means, chi-square test, and t-test. Over half (52.1%) of the respondents were institutional foodservice directors, 47.9% of the respondents were commercial foodservice directors. The majority of institutional foodservice directors were 25-29 years of age (38.6%), over 10 years of working experience (63.6%) and commercial foodservice directors were 25-29 years of age (53.1%), 5-10 years of working experience (35.0%). 66.3% of the respondents were educated food safety once a month, but 8.6% of commercial foodservices were never educated. The majority of the respondents used printing materials (73.3%) or lecture (74.8%). The importance level of institutional foodservice directors about sanitation education was significantly higher than commercial foodservice directors. The average score of institutional foodservice directors' sanitation knowledge was 87.05/100.00. The commercial foodservice directors' sanitation knowledge 67.74 was significantly lower than institutional foodservice directors (p < 0.05). Therefore, there should be a systematic education program designed for commercial foodservice directors.

Fermentation plays a vital role in the nutritional enrichment of food. Korea has a long tradition of adding fermented food to the daily diet and jeotgal is one of the common fermented and salted foods in Korean cuisine. In our study, we added soymilk as an additive to squid jeotgal to improve its functionality. We mixed different concentrations of soymilk (2, 5, and 10 mg/g) with squid jeotgal samples, fermented them for one week, and then tested their antioxidant and anticancer activities to compare with those of squid jeotgal samples without soymilk additive. To investigate the anticancer characteristics, glutathione-S-transferase (GST)-pi enzyme assay was used. To test the antioxidant activities, various assays were performed, including 2,2-diphenyl-1-picryl hydrazyl free radical scavenging activity, 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium saltradical cation scavenging assay, and reducing power assay. Samples fermented with a small amount of soymilk showed excellent anticancer activity. The addition of only 2 mg/g of soymilk to squid jeotgal inhibited the activity of GST-pi by almost 50% when compared with the sample with no addition. Moreover, no undesirable bitterness or astringency was noticed. Our results could help to improve the current food status of squid jeotgal and it could be used to reduce the risk of chronic disease along with its basic nutritional function.

The purpose of this study was to develop cultural food contents from local dishes related to the historical and cultural heritage in the representative areas of Gurye and Jinan. The information on 'Story' was collected from each region's representative local native journal, searches of related web-sites, analysis of old literature, and interviews of traditional households. 'Telling', the conveyance, was focused on texts of literature analysis, which were synthesized from historical conditions, regional food materials, cuisine, regional symbolism, etc. The created food contents were displayed with balanced and healthy Korean food dishes after nutritional analysis. In Gurye, the content was extracted from the story of Hwang hyun (黃玹, 1855-1910) - figura of Gurye - and his collection, "Maecheonyarok", and the storytelling native food was prepared. In Jinan, the content was extracted from the text of an anecdote from "filial son Kwang-beom Lee", a local journal. We tried to express Gurye's clean image in connection with the patriot - Hwang hyun (his nick name was Maecheon), in the late period of Chosun through the unprocessed and simple nature of the dining table. As in Jinan's storytelling materials, we tried to express a healthy menu of health food for older people based on the clean nature and documents about the real character's filial behavior. The developed healthy menu and dining table properties in this study have been established in accordance with nutrient intake standards of energy in Korea.

This study will introduce the foods recorded in Gyemiseo and disclose the substantive characteristics of traditional Korean food in the early stage of the Joseon Dynasty. Gyemiseo is a cook book manuscript written in the Chinese language that was rebound into book format at the end of the Joseon Dynasty in 1911, some 358 years after it was originally written in the $163^{rd}$ year of the Joseon Dynasty (1554) While the majority of cook books begin with recipes for various types of wines and liquor followed by those for fermented sauces, fermented vegetables (such as kimchi), vinegars and storage methods, etc., Gyemiseo begins with recipes for fermented sauces, followed by recipes for various kimchis, how to make vinegars, main meals, side dishes, rice cakes and confectionaries, with recipes for wines and liquor introduced last. Therefore, it can be assumed that the methods of brewing wines and liquors were additionally recorded for bookbinding. There are a total of 128 recipes recorded in Gyemiseo, including 13 for fermented sauces, 14 for kimchi, 11 for the main meal, 26 for side dishes, three storage methods, four for rice cakes and confectionaries, and 44 for wines and liquors. It is believed that contents of Gyemiseo will provide a foundation on which to pursue researches on the process of transition of cooking methods of traditional cuisines of Korea during the Joseon Dynasty.

This study was performed to examine the physicochemical characteristics and sensory properties of makgeolli with dried citron peel and levels (3, 6, and 9%) of citron (Citrus junos) in makgeolli during fermentation with two-step-brewing. The pH of makgeolli with citron dried peel increased within 5 days of fermentation, and decreased until 11 days of fermentation. Total acidity increased after 3 days of fermentation then decreased after 5 days of fermentation, but continued to increase slightly up to 12 days. Changes in alcohol content and amino acidity increased during fermentation. A sensoryevaluation of appearance, flavor, sourness, sweetness, bitterness, and overall acceptance of makgeolli with citron dried peel showed lower values than those of the control.

In this study, the approximate compositions, color properties, texture properties, physical characteristics, and sensory evaluation of muffins prepared from legumes (mung bean, cowpea, chickpea, or lentil) and wheat flour blends was evaluated. Pasting viscosity of legume flours was lower than that of wheat flour. The moisture, crude ash, and crude protein content of muffins made with legume-wheat flour blends were higher than those of control muffins made exclusively with wheat flour. The lightness value of muffins was decreased by adding legume flour. The hardness of muffins made from legume-wheat flour blends was higher than that of control, whereas springiness and cohesiveness was lower. The weight of muffins made with legume-wheat flour blends were higher than that of control, whereas the height and volume were lower than those of control. The scores of taste, aroma, and texture of muffins were not significantly changed by adding legume flours. The overall acceptability of muffins that were made with lentil or chickpea flour was similar to that of control muffins.

There is increasing interest in developing flavor-enriched concentrate using byproducts of skipjack tuna Ktsuwonus pelamis as a replacement for commercial beef bone extract concentrate (CBB-EC). This study was compared on sanitary and nutritional characteristics between skipjack tuna frame extract concentrate (ST-EC) and CBB-EC as a control of skipjack tuna frame extract concentrate. The moisture contents of CBB-EC and ST-EC 41.4-4.9% and 45.3%, respectively. The results of viable cell counts and E. coli assays suggested that CBB-EC and ST-EC is a safe and sanitary for use in food. There were no differences in peroxide values among CBB-ECs. The total amino acid contents in CBB-EC and ST-EC were 25.6-29.3 g/100 g and 37.9 g/100 g, respectively, and the major amino acids present glutamic acid, proline, glycine, alanine and arginine. Regardless of kinds of the mineral, mineral contents of ST-EC higher than those of CBB-EC. The major fatty acids were 16:0, 18:0 and 18:1n-9 in CBB-EC, 16:0, 18:1n-9 and 22:6n-3 in ST-EC. These results can be used as background information to develop flavor-enriched concentrates from byproducts of skipjack tuna as replacement for CBB-EC.

This study aimed at helping to raise the reputation of Tteokgalbi for tourists visiting Damyang by studying the plating of Tteokgalbi. For 15 representative restaurants selling Tteokgalbi, we investigated the balance, blank, and proportions through studying the shape, material, and size of the dishes, and the number, shape, and garnish of one serving size of Teokgalbi. The results of our study suggested that round dishes (7 restaurants) and elliptical dishes (6 restaurants) similar to the shape of Teokgalbi are mainly used. For 13 out of 15 restaurants, the dishes were mainly casting pans in order to serve Tteokgalbi warm. The diameters of round dishes were 230 mm (3 restaurants), 265 mm (2 restaurants), and 300 mm (2 restaurants), and the elliptical dishes mostly had widths of 150 mm and lengths of 240 mm. The color of the dishes was N2-N3, similar to black, and N1, black of pale colors, because the dishes were mainly casting pans. The number of Teokgalbi per serving size was 3 in 12 restaurants. whole sesame was used most (7 restaurants) as a garnish. The results suggested that the color of the dishes and garnish could not imbue much distinction in the color of Tteokgalbi. In other words, Tteokgalbi is now served without consideration of the color, shape, size, or material of Tteokgalbi. The size of Tteokgalbi should be decided with consideration for the size of the dish and the amount of one serving size, and it is necessary to keep studying the process of making and garnish of Tteokgalbi.

This study was carried out to investigate the mechanical and sensory properties of Teriyaki sauce made with different boiling time(6, 8, 10 and 12 hrs). The results were as follows. As for the mechanical characteristics, moisture contents, L-value, a-value, salinity and pH decreased with increasing boiling time. On the other way, viscosity, b-value and sugar contents of Teriyaki sauce increased with increasing boiling time. From results of quantitative descriptive analysis, offensive flavor was significantly different when examining Teriyaki sauce alone, but there was no difference when the sauce was accompanied with food. The 8 hr-boiling sauce was favored most in chicken with Teriyaki sauce, and 10hr-boiling sauce was favored most in eel.
