Unit price of meal provision in industrial foodservice differs with each business. It is believed that menu management work, contents of menu, and nutrition supply performed by dietitian are different with unit price of meal provision. In this sense, purposes of this study are to examine meal management work and contents of menu, by food cost, at industrial foodservice in Taegu, Kyungbuk area and to evaluate variety of menu and nutrition supply. Results of the study are as follows: 1. Average number of side dishes provided at meal, including Kimchi, was 2 at low unit price, 3.0 at middle unit price and 3.1 at high unit price. 2. Possession ratio of account books using for menu management was low. 3. With regard to kind of menu, high unit price was most various and showed more various, compared to low unit price, especially in cooking oil-used cook methods such as broil, pan-fried food, fry, and roast. 4. High unit price was found as the highest in kind of used food and supply volume. 5. Sugar, Mineral, Vitamine, and Protein were satisfied with standard food content, but fat and calcium were not. 6. Supply volume of food was positively correlated to supply volume of nutrient, but kinds of cook methods and food type were not correlated to that of nutrient.

Algeria is located at the Mediterranean coast of north Africa, 90% of its population is concentrated in the coastal area which is mainly devoted to agriculture. Highland steppe and vast desert climate have determined its food culture. Long arab domination has influenced food of Algeria which has also undergone certain impact of Spanish, Turkish and French occupation. A variety of agricultural products, vegetables, fruits, spices and herbs have determined cooking method and food combination of Algeria. It use neither pork nor alcohol. Its main food consists of bread made from wheat flour and couscous cooked with semoule, Mechuwi, roast lamb and chorba, mixed soup are also typical foods of this region. For climatic reason lamb and chicken are prefered. Energy efficient method is applied to cooking through using oil for saute and water for boiling. Under european influence, Algerian salad used dressing for leaf vegetables, root and other kind vegetables were boiled. Serving with cake and cookies as dessert may possibly be the influence from the French occupation. The cake and cookie are made of wheat flour or other grain flour and take a specific form to be fried sweet with honey. Herbs and spices are widely used in cooking which are easily cultivated in household: mint, basil, rosemary, bayleaf, thyme, sage, fennel, marjoram, coriander, celery. Garlic, onion, piment, red pepper, cinammon are also widely used in an ordinary cooking. Reasonable food combination and economic cooking method could be subject of Algerian food study.

This study was performed by questionnaire to investigate the preference and satisfaction on the menu of school foodservice of high school students. This study aims at providing useful information to establish subdivided menu developing direction. The subjects were consisted of 637 high school students(435 males and 202 females, 5 direct type schools and 5 trust type schools) in Gyeongju area. The results of this study were: The preferred school foodservice menu of subjects was 'seasoned roast chicken', 'steamed pork rib', 'beef rib soup', 'yogurt', 'sandwiches', 'boiled rice with assorted mixtures', 'boiled rice', 'watermelon', 'spaghetti' in that other. On the other hand, the preference for 'spinach soybean soup', 'steamed Mideodeok', 'boiled lotus root', 'roasted sweetpotato stalk', 'chopped and seasoned cucumber' was very low. Males favoured rice and meats, while females liked better noodles and vegetables. Direct type foodservice students' preference scores were higher than those of type foodservice students in side dish menu categories. The preferred and satisfied menu of subjects was meats and sweet foods, and but the preference and satisfaction for vegetables and tough foods was very low.

Processed foods containing pork fat tissue to improve flavor and gain economic benefit may cause severe issues for Muslims, Jews, and vegetarians. This study aimed to develop an indirect enzyme-linked immunosorbent assay (iELISA) based on a monoclonal antibody specific to thermal stable-soluble protein in pork fat tissue and apply it to detect pork fat tissue in heat-processed (autoclave, steam, roast, and fry) beef meatballs. To develop a sensitive iELISA, the optimal sample pre-cooking time, coating conditions, primary and secondary dilution time, and various buffer systems were tested. The change in the iELISA sensitivity with different 96-well microtiter microplates was confirmed. The detection limit of iELISA performed with an appropriate microplate was 0.015% (w/w) pork fat in raw and heat-treated beef. No cross-reactions to other meats or fats were shown. These results mean that the iELISA can be used as an analytical method to detect trace amounts of pork fat mixed in beef.

The purpose of the present study was to evaluate the sensory and instrumental quality of thawed beef steak prepared by searing and oven cooking. Beef purchased in the local market was divided into two groups; one group was cooked in a 180℃ oven until the internal temperature reached 60℃, and the other group was oven cooked until 35℃, then cooked in a 250℃ pan until the internal temperature reached 60℃. Despite a noticeable change in appearance due to the high temperature of the searing, there was no significant difference in juiciness, water content, and cooking loss between the searing-cooked and the oven-cooked steaks. However, in searing cooking, both scores of overall flavor and roast meat flavor were significantly higher than those of oven cooking. In the searing-cooked steak, the reducing sugar, which is a reactant of the Maillard reaction, was lower and Maillard-reaction products were higher than oven-cooked steak. From our results, it can be concluded that searing does not improve juiciness of the steak, but improves the flavor of beef steak due to higher levels of Maillard reaction products.

Members of the genus Brassica, which are known as oil crops or cruciferous vegetables, are widely cultivated in Canada, Australia, Asian and Europe. Because Brassica species have high yields, are well adapted to their environments, and are self-incompatible, the germplasm is abundant. Previous studies have reported abundant genetic diversity even within Brassica subspecies. In Korea, fresh cabbage leaves are eaten with roast meat, and to meet the current popular demand, new varieties are being increasingly bred. To determine the genetic diversity and relationships among the cabbage vegetables in Korea, we evaluated the genetic variation of 18 accessions based on 5S and 18S ribosomal RNA (rRNA) gene sequences. We detected many variable nucleotide sites, especially in the 5S rRNA gene sequences. Because the length of the 18S rRNA gene might influence the dissimilarity rate statistics, we used both the 5S and 18S sequences to analyze the phylogenetic relationships. S7 (B. oleracea) showed the most distant phylogenetic relationship with the other Brassica species. Interestingly, B2 (B. oleracea), B15, and B18 (B. campestris) have three different types of leaf profiles, and were divided into one group, and the other Brassica species formed another group. Statistical analysis of interspecies and intraspecies genetic distances revealed that B. campestris L. showed higher genetic diversity than B. oleracea L. This work provides additional data that facilitates the evaluation of the genetic variation and relationships among Brassica species. The results could be used in functional plant breeding programs to improve Brassica crops.

The objective of this study was to investigate free amino acid composition, antioxidant activity, alcohol dehydrogenase activity and the sensory quality attributes for the development of functional soy sauce using Hutgae (Hovenia dulcis Thunb) fruit, which is well-known for improving liver function and alleviating various negative physiological effects following heavy consumption of alcoholic beverages. Soy sauces adding six types of extract from Hutgae fruit (HF) were prepared (SSH1: HF 20%, SSH2: HF 10%, SSH3: HF 20%/40 days NaCl extract, SSH4: HF 20%/20 days NaCl extract, SSH5: HF 20% water bath extract, SSH6: freeze-drying powder from HF 20% aqueous extract), compared with soy sauce using the conventional method. These soy sauces were used for determining alcohol dehydrogenase activity by NADH absorbance, the antioxidant effect by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and sensory evaluation by sensory scaling. Total free amino acid contents for most samples were in the range of 327.3 to 375.5 mg%, and then, aspartic acid and glutamic acid content of SSH1 and SSH5 were higher than that of others. DPPH radical scavenging activity was shown to be the highest in SSH4, also SSH1, SSH5 and SSF6 were shown to be higher than the control group. Alcohol dehydrogenase activity was shown to be the highest in SSH5. In sensory evaluation, the highest intensity of roast smell was observed in SSH4 while sweet taste was shown to be the highest in SSH5, and SSH3 and SSH5 revealed higher overall acceptability. From these results, Hutgae fruit soy sauces demonstrated antioxidant activity and alcohol dehydrogenase activity. In conclusion, soy sauces containing the water bath extract of Hutgae fruit may be used as a functional seasoning.

Annual variations In main fishing grounds of common squid with different angling and their fishing conditions in Korean waters were studied by analyzing catch and water temperature data. The main fishing grounds of squid angling fishery started to moved to the north in April and to the south in September in the last Sea of Korea. The catch of squid was related to the direction of thermal fronts. The catch was high when the thermal front was formed in the east-west direction, while there was low catch when the thermal front was formed in the south-north direction which runs parallel to the roast.

A mass fecal examination was performed in Seoul, Korea from December 1983 to March 1984 and 15 egg positive cases of Fibricola seoulensis were discovered. They were treated with praziquantel($Distocide{\circledR}$) 20mg/kg single dose and magnesium salt for purgation. The adult worms of F. seoulensis were collected from 6 of them. The number of the flukes ranged 1-78 by the case. The cases had no clinical manifestation at all. They were all Korean males in twenties, and had the histories of eating the roast or raw snakes or frogs. Fibricoliasis is expected to be prevalent among the snake-eaters in Korea. Further cases will be detected by sedulous differentiation of thinshelled immature operculated eggs of 0.08~0.102mmn length. Praziquantel seems to be an excellent chemotherapeutic for fibricoliasis.
