This study was conducted to determine the effect of different proportions of Alaska pollack surimi, chicken breast surimi and starch on textural properties of sausage. Sausage were manufactured such as Alaska pollack surimi(control), T1(90.91:0:9.09), T2(80:0:20), T3(62.5:37.5:0), T4(58.82:35.3:5.88), T5 (40:60:0) and T6(36.36:54.55:9.09) depending on different proportions of Alaska pollack surimi, chicken breast surimi and starch. Brittleness, breaking force and gel strength were significantly higher in T1 than the control(P<0.05), and breaking force, gel strength and folding test were significantly higher but sensory evaluation was significantly lower in T2 than the control(P<0.05). Breaking force, gel strength and jelly strength were significantly higher in T3 and T4 than the control(P<0.05). Gel characteristics and sensory scores were significantly higher but texture properties were significantly lower in T5 and T6 than the control(P<0.05). The T3 and T4 had similar textural and sensory properties in the surimi- sausage compared to the control. Therefore, the results of this study indicated that textural properties of sausage can be acceptable when chicken breast surimi replaced Alaska pollack up to 35%.

A bacteriological survey for 20 large grocery stores (M 1 to M20) in Korea was investigated for one year. The average detection rate of Esherichia coli was $22\%$ (166/763) for 7 kinds of ready-to-eat food through the year, where each grocery store and each type of food showed different detection rates. Eleven grocery stores showed lower detection rates, while 9 grocery stores showed a higher than average rate. Especially, M3 showed a rate that was twice as high as the average and one which was 7 times higher than M14, which had the lowest rate of $6\%$ E. coli detection. The detection rate for each type of food was: $38\%$ (41/109) for Kimbop, $31\%$ (34/109) for vegetable salad, $19\%$ (21/109) for bean-curd, $18\%$ (20/109) for the cooked materials used in making Kimbop, $17\%$ (19/109) for Hoe (sliced raw fish) and Sushi (Japanese vinegared rice delicacies), and $11\%$ (12/109) for cooked pork hock. During the summer, the E. coli detection rate averaged $43\%$ (71/166), which was twice as high as other seasons. Most (89/100) of the food contacting surfaces contained more than the critical limit $(1.3\;log_{10}\;CFU/10cm^2)$ of aerobic viable cell counts (AVC). The $log_{10}$ AVC and $log_{10}$ coliform count (CC) of 218 meat samples (beef, pork, and chicken) ranged between 4.6-7.1 CFU/g and 1.9-6.4 CFU/g, except for 41 meat samples $(19\%)$ which were found to contain no coliform. There was a definite correlation between the $log_{10}$ AVC and $log_{10}$ CC, and the values of $log_{10}$ CC made a more accurate straight than the $log_{10}$ AVC, which are variable. From these results, it is suggested that a detection rating of less than 2.1 CFU/g of $log_{10}$ CC (correspond to 5.0 CFU/g of $log_{10}$ AVC) is the critical point of freshness, and a rating of more than 6.3 CFU/g of $log_{10}$ CC (correspond to 7.0 CFU/g of $log_{10}$ AVC) can be considered an initial spoilage point.

Background: The aim of this study was to investigate demographic features, dietary habits, and some possible risk factors for being susceptible to breast cancer in Iranian women. Materials and Methods: A study of dietary habits and breast cancer was conducted among 53 Iranian women with histological confirmed disease and 40 matched controls. A dietary habits questionnaire was used to evaluate the pattern of selected food intakes. The risk of cancer was analyzed after adjustment for confounding factors. Age, weight, body mass index (BMI), waist circumference, educational status, parity, lactation, marital status, menopause, history of estrogen therapy, and family history of breast disease or cancer were assessed among participants. Special attention was given to the relationship between consumption of high fat meat, milk, yogurt and cheese as well use of frying oils for frying foods, use of olive/liquid oils for cooking, removing fat from meat and poultry, removing chicken skin and not use of mayonnaise as salad dressing and the risk of breast cancer. Moreover, salad, vegetable and fruit consumption, and eating outdoors owere investigated. Results: Our results revealed significant lower education and higher BMI and waist circumference levels in patients with breast cancer. There was significantly increased breast cancer risk in overweight women in comparison with normal weight (OR=2.91, 95%CI 1.24 to 6.82). High intake of fat dairy products including milk and cheese was found to be a statistically significant factor for increasing breast cancer risk in models adjusting for age, BMI and education. Use of olive/liquid oils for cooking and avoidance of mayonnaise as salad dressing are related to lower risk of breast cancer. The frequency of vegetable and fruit consumption was significantly lower in patients with breast cancer compared to healthy women. Conclusions: Dietary habits might be risk factors for breast cancer among Iranian women. Adoption of a prudent diet could be an appropriate strategy for preventing breast cancer.

Background: Lung cancer is one of the most prevalent malignancies in the world and both incidence and mortality rates are continuing to rise in Pakistan. However, epidemiological studies to identify common lung cancer determinants in the Pakistani population have been limited. Materials and Methods: In this retrospective case-control study, 400 cases and 800 controls were enrolled from different hospitals of all provinces of Pakistan. Information about socio-demographic, occupational, lifestyle and dietary variables was extracted by questionnaire from all subjects. Odd ratios (ORs) and 95% confidence intervals (CIs) were calculated. and dose-response associations were also assessed for suitable factors. Results: Strong associations were observed for smoking (OR=9.4, 95%CI=6.9-12.8), pesticide exposure (OR=5.1, 95%CI=3.1-8.3), exposure to diesel exhaust (OR=3.1, 95%CI=2.1-4.5), red meat consumption (OR=2.9, 95%CI=1.8-4.7) and chicken consumption (OR=2.8, 95%CI=1.7-49). Other associated factors observed were welding fumes (OR=2.5, 95%CI=1.0-6.5), sedentary living (OR=2.0, 95%CI=1.6-2.6), family history (OR=2.0, 95%CI=0.8-4.9), wood dust (OR=1.9, 95%CI=1.2-3.1), tea consumption (OR=1.8, 95%CI=1.2-2.6), coffee consumption (OR=1.8, 95%CI=1.1-2.8), alcoholism (OR=1.7, 95%CI=1.1-2.5) and asbestos exposure(OR=1.5, 95%CI=0.5-4.4). Consumption of vegetables (OR=0.3, 95%CI=0.2-0.4), juices (OR=0.3, 95%CI=0.3-0.4), fruits (OR=0.7, 95%CI=0.5-0.9) and milk (OR=0.6, 95%CI=0.5-0.8) showed reduction in risk of lung cancer. Strongest dose-response relationships were observed for smoking ($X^2=333.8$, $p{\leq}0.0000001$), pesticide exposure ($X^2=50.9$, $p{\leq}0.0000001$) and exposure to diesel exhaust ($X^2=51.8$, $p{\leq}0.0000001$). Conclusions: Smoking, pesticide exposure, diesel exhaust and meat consumption are main lung cancer determinants in Pakistan. Consuming vegetables, fruits, milk and juices can reduce the risk of lung cancer risk, as in other countries.

Purpose: This study was conducted in order to analyze the dietary habits and food intake status according to the prevalence of depression in adults. Methods: A total of 496 subjects, 224 men and 272 women aged 50 to 100 years were recruited from more than 13 cities in Korea. The questionnaires consisted of general characteristics, dietary life status, food intakes, the mean mini dietary assessment and satisfaction with food-related life questionnaire of the subjects to ask according to the degree of depression. Depression status was evaluated according to the Korean form of the Geriatric Depression Scale (K-GDS). Results: All subjects were divided into depression or normal groups; the prevalence of depression was 13.8% (male) and 23.9% (female). People aged 65 or older were more likely to have higher prevalence of depression and to be bereaved. People in the depression group had poor appetite, almost never dined-out, and ate alone. The food intake of miscellaneous cereals, beans, tofu, chicken/duck meat, cabbage, carrot/amber, fungi, apple, pear, strawberry, grapes, and banana was significantly higher in the normal group compared with the depression group. In particular, significantly higher intake of vegetables and fruits was observed in the normal group. In addition, subjects in the depression group ate more fatty meat and were more dissatisfied with food-related life than those in the normal group. Conclusion: The results of this study imply that the prevalence of depression may affect the dietary habits, food intake, and dietary behaviors in the older adult population.

This study was conducted to compare the general composition and immunomodulatory activity of breast and thigh meats from four lines of Korean native chickens: Yeonsan Ogye, Hyunin Black, Hwangbong, and Hoengseong Yakdak. White Leghorn was used as a control. Fifteen male chickens (three chickens in each line) were grown under the same conditions and slaughtered at 13 weeks old. The four lines of Korean native chickens, regardless of the part, had higher contents of crude fat (p<0.05) than White Leghorn. The cholesterol contents were significantly higher in Hyunin Black and significantly lower in Hoengseong Yakdak than those of other chickens (p<0.05). The immunomodulatory effect, assessed by macrophage cell proliferation and nitric oxide production, was only observed in the breast meat of the four lines of Korean native chickens. The phagocytic activity of macrophage cells was significantly augmented by the breast meat of Hyunin Black and Hoengseong Yakdak. Furthermore, the mRNA expressions of pro-inflammatory cytokines, such as IL-4, IL-10 and $IFN-{\gamma}$, was significantly suppressed by Korean native chickens compared with White Leghorn. These results suggested that the four lines of Korean native chickens exhibited greater immune-enhancing activity than White Leghorn.

The purpose of the present study is to assess nutrient content for providing nutrition information such as nutrition labeling on Korean dishes in restaurant and food service institutions. The content of nutrients was calculated in recipies used to prepare dishes which has been frequently consumed in such four groups as the literature, foodservice institutions of industries, restaurants, and households. The numbers of dishes surveyed were 15. Total numbers of literture used for recipies analysis are 20. Recipies used in foodservice institutions of industries were abstracted from the journal 'Guk-Min Young-Yang' published in Korea dietetic association and obtained with the help of dietitians working in those institutions. Also, recipies has been using in restaurants were given from the Korea restaurant association. Recipies in households was calculated from the secondary analysis of the Korean National Nutrition Survey. Nutrient content from foods except steamed rice and side dishes in each dish was calculated using data of Korean food composition table published. The content of energy and protein in 'Gal-bi tang' (beef-rib soup) were highest in recipes used at restaurants, vitamin C in recipes of food service institutions of industries due to the generous use of meats and vegetables than other recipies. 'Doen-jang chigae' (soybean paste stew) showed the lowest content of energy in results analyzing recipes presented on the literature and varied protein level by four groups for difference of protein source used. The content of energy in 'Gop-chang jeongol' (small intestines stew) is 150 kcal more than 'Soegogi jeongol' (beef stew) in general. The energy level of 'Daeji-galbi' jim (braised pork ribs) and 'Dak jim' (braised chicken) turned out to be the highest in recipies presented on literature. Variation of each nutrient content including energy and protein was relatively high, since some of foods used in 'Pibimbab' (mixed rice) varied with four groups. Amounts of energy and protein in 'Naeng-myeun' (cold noodles) is the highest in recipies of foodservice institution of industries because much amounts of noodle and meats were used comparing to other groups. The average content of energy in 'Pulgogi' (grilled meat with sauce) was 50% to Korea recommended amounts of one meal, 833.3 kcal. Content of vitamin $B_1$ in 'Jeuk pyeunuk' (boiled pork), which is made of pork meat, was higher than other dishes. The ingredients of frequently consumed Korean dishes were highly variable among the four groups which inevitably results in variation of nutrient content in each dishes. The high variation of nutrient content in each dish according to study requires careful collecting of the large number of recipies in presenting representative nutrient content for nutrition labeling on dishes in restaurant and food service institutions effectively.

The purpose of this study was to survey the recognition and the actual state of use of Native pork. The recognition on Native pork were examined using a questionary to eight hundred males and females in Kyeongbuk and Daegu. The results were as follows : The meats which they often ate in the order of pork, beef and chicken. When people eat out, 43.7% of those ate pork and 42.7% of those ate beef, the younger people liked pork more than the older people. The recognition on pork dishes showed the a high mean value of 3.38 to "I like Pork dishes" 53.5% of the respondants liked three-ply flesh and 33.6% of those liked rib among the part of pork. The favorite pork dish was pork roast meat at 48.1 o/e, Kimchichige at 13.6%, and sweet and sour pork 10.9%. Suitable and garnish food with pork were lettuce, sesame leaf and garlic, and alcoholic drinks such as soju. The Native pork showed a higher mean value than improved pork in taste(lightness, tasty) . sticky meat qualify, low fat content and good food for health. 30.9% of the respondants recognised as a traditional food. 59.1% of respondants have used the native pork, ingest place came out special eating house 42.2%. 38.3% of respondants suggested' convenience of purchase' and 31.6% of those suggested 'low price' as facts that has been improved in the native pork.tive pork.

This research was performed to identify the components and types of comfort foods and to verify gender differences on choosing comfort food in various emotional states. The total of 425 Korean college students participated in this study. The results are as follows. First, most students rated foods that give warmth and relaxation, foods that are reminiscent of happy memories, food that tastes good, were rated as types of comfort foods. On the other hand, external condition and fast food were less likely to be rated as a comfort food. Second, male students reported meat dishes, stew or soup, and alcohol as comfort foods whereas female students reported stew or soup, fruit or vegetable, and meat dishes as comfort foods. Third, the students chose different comfort food in different emotional states. In negative emotions, most students chose alcohol, chocolate, hot (spicy) food, and drinks as a comfort food. But in positive emotions, most students chose chicken as comfort foods. While male students chose alcohol as high ranking comfort food, female students chose various foods as their comfort food. The limitations of this study and suggestions for future studies were discussed.

This study was conducted to determine the effects of dietary supplementation with conjugated linoleic acid (CLA) feeding levels (0, 0.5, 1.0, 1.5, and 2.0%) on the carcass characteristics, growth performance, serum cholesterol, and fatty acid in thigh of chicken meat. Two hundred broiler (Arbor Acre Broiler, male) were randomly assigned to five groups and were fed for five weeks and slaughtered. Thigh muscle was used for determining fatty acid composition. There was no significant difference in growth performance, such as weight gain, feed intake and feed conversion by CLA levels. Among carcass characteristics, percentage of carcass, thigh, breast, and drumstick was not influenced by the dietary CLA levels, but abdominal fat was significantly reduced with the increased CLA amount in the broilers diets (p<0.05). Higher CLA levels increased HDL-C and reduced total cholesterol and LDL-C (p<0.05). As the dietary CLA levels increased, muscular palmitic acid (saturated fatty acid) levels was increased, but the rates of oleic acid, linoleic acid, and arachidonic acid (unsaturated fatty acid) were decreased. In addition. CLA isomers were linearly increased with the increase in dietary CLA levels (p<0.05). As a conclusion, 2% of CLA feeding is possible to maximize accumulation of CLA in meat, but changes in fatty acid composition is not profitable. Therefore, 1% of CLA feeding i,j considered to be proper for accumulation of CLA and minimization of the change in fatty acid.
