  • The informations concerning knowledge, value and consumption pattern for rice foods of elementary schoolchildren (630 boys and 550 girls in 5th or 6th grade) were investigated in Changwon and Gimhae of Gyeongnam province. They were asked based on knowledge, one’s value and intake frequence of rice foods by questionnaries. Menus for 3 days including 2 weekdays and 1 weekend day were taken from 136 students (77 boys and 59 girls) in two Elementary Schools in Changwon and Gimhae to know intake reality of rice product. The purpose of this survey was to find the way of encouraging rice intake and preference which now seemed to be low because of simplified, westernized eating habits, and to provide basic information needed for inheriting and improving our traditional cooked rice centered eating culture. The results are summarized as follows. The knowledge of rice was positively correlated to the one’s value (r=0.365, p<0.001) and the preference (r=0.132, p<0.001), the one’s value was positively correlated to preference (r=0.409, p<0.001). The score of knowledge for rice was 12.8 points out of 20, the girls get points(13.12) significantly higher than the boys (12.53) (p<0.01). One's value about rice foods was 37.35 points out of 50 what is relatively high. They have eaten cooked rice type food for 2.24 times per day. Both boys and girls in Changwon and Gimhae area were having cooked rice type food significantly more during weekdays compared to weekends (p<0.001) by 3 days food record. According the results, we can see the possibility that schoolchildren can be encouraged to eat more rice foods by nutritional education to go with the development of various programs.

  • Background: New alternative types of pet foods such as raw and cooked homemadestyle diets containing human food ingredients have been introduced due to a trend of pet humanization and diversification of consumer needs. Objectives: To evaluate nutritional adequacy of new alternative types of dog foods containing human food ingredients as maintenance diets for dogs. Methods: Eleven homemade-style foods for adult dogs were purchased from online channel in Korea and analyzed to evaluate nutritional adequacy for adult dogs. Nutrients analyzed included crude protein, amino acids, crude fat, fatty acids, and minerals. Results: Crude protein and amino acids in all products satisfied Association of American Feed Control Officials (AAFCO) requirements. Crude fat in one of 11 products did not meet AAFCO requirements. The most deficient minerals were selenium (10 of 11, 90.9%), copper (five of 11, 45.5%), zinc (five of 11, 45.5%), potassium (three of 11, 27.3%), calcium (three of 11, 27.3%), iron (two of 11, 18.2%), and magnesium (one of 11, 9.1%). Six products were not in the range of the recommended Ca:P ratio in AAFCO dog food maintenance nutrient profiles. Conclusions: This study performed nutritional evaluation of raw and cooked homemadestyle foods as maintenance diets for adult dogs. Some nutritional inadequacies were observed including some minerals, Ca:P ratio, and omega-6:omega-3 fatty acid ratio, although three products (26.2%) satisfied the AAFCO standard except selenium. Overall, the data suggest a need for accurate nutritional adequacy statement for consumers based on proper methods to validate the formula.

  • Sasa borealis leaf has been known to have anti-diabetic properties. In this study, we tried to evaluate the effects of Sasa borealis leaf extract (SBE) on the inhibition of $\alpha$-glucosidase activity and postprandial glycemic response following ingestion of four carbohydrate-rich foods; cooked rice, ramen (instant noodle), noodle, and bread. Fourteen healthy female adults consumed 50 g of glucose (control) or one of the four foods containing 50 g of available carbohydrate with or without 2,000 mg of SBE. The activity of $\alpha$-glucosidase was inhibited dose-dependently by SBE. With SBE, blood glucose concentration at 15 min and the positive area under the curve (AUC) of postprandial glycemic response at 15 min and 30 min after consuming each of the four foods were reduced significantly. As the result, total positive AUC during 120 min was decreased in case of taking cooked rice or bread. Glycemic index and glycemic load of the four foods were declined from 13% to 23% with SBE. The results of this study suggest that SBE may be effective for postprandial glucose control by inhibiting $\alpha$-glucosidase activity.

  • The microstructure, contents of pectic substances and textural properties of cell masses separated from cooked kindey bean and soybean were investigated. Cooked kidney bean could be easily separated to the individual cells, while soybean yielded mixture of individual cells and cell clusters. The break down of the middle lamella was observed, but cell wall was not injured . Separated cells from kidney bean were spherical, while those from soybean were long sack shape as observed in both optical microscope and SEM. Cooked soybean cell mass, which had higher content of pectic substances, showed higher cohesiveness and adhesiveness compared to kidney bean cell mass.

  • To develop a optimized method for educing the errors associated with the estimation of portion size of foods, fuzzy-dta processing of portion size was performed. Cooked-rice was chosen as a food item. The experiment was conducted in two parts. First, to study the conceptions of respondents to bowl size(large, medium, small), 11 bowls of different size and shape were used and measured the actual weights of cooked-rice. Second, to study the conceptions of respondents to volume(1, 1/2, 1/3, 1/4), 16 different volumes of cooked-rice in bowls of same size and shape were used. Respondents for this study were 31 graduate students. After collecting the data of respondents to size and volume, fuzzy sets of size and volume were produced. The critical values were calculated by defuzzification(mean of maximum method, center of area method). The differences of the weights of cooked-rice in various bowl size and volume between the critical values and the calculated values by average portion size using in conventional methods were compared. The results hows large inter-subject variation in conception to bowl size, especially in large size. However, conception of respondents to volume is relatively accurate. Conception to bowl size seems to be influenced by bowl shape. Considering that the new fuzzy set was calculated by cartesian product(bowl size and volume), bowl shape should be considered in estimation of bowl size to make more accurate fuzzy set for cooked-rice portion size. The limitations of this study were discussed. If more accurate data for size and volume of many other food items are collected by the increased number of respondents, reducing the errors associated with the estimation of portion size of foods and rapid processing will be possible by constructing computer processing systems.

  • This study was undertaken to determined the metabolizable energy of cereal by the different method. Raw or cooked cereal foods were freeze-dried and fed to Sprague Dawley rat with 200-300g body weight to measure apparent metabolizable energy(AME) values and nitrogen-corrected AME(AMEn) values for four days after three days of preliminary period for adaptation to the diets. The AME values of Karaeddok, raw rice, cooked rice, raw brown rice, raw glutinous rice, cooked glutinous rice, raw barley and cooked barley applerared 4516.1, 3380.6, 4072.2, 3457.0, 4448.0, 2929.4 and 3780.2kcal/kg dry matter, respectively. The AMEn values of karaeddok, raw rice, cooked rice, raw brown rice, cooked brown rice, raw glutinous rice, cooked glutinous rice, raw barley and cooked barley appeared 4421.5, 3349.6, 4160.0, 3918.7, 4039.3, 3572.0, 4552.5, 3009.9 and 3873.4kcal/kg dry matter, respectively. A slight difference was observed when the AME values of the cereals measured in present study were compared with the energy values calculated by various conversion parameters such as Atwater's, Rubner's, Sochun's adn FAO's, indicating that the latter energy values by all conversion factors are acceptabel for several cereals.

  • This study was conducted to investigate mean height, weight, food preference and satisfaction of 231 children in preschool in four different regions(Susung-ku, Jung-ku, Nam-ku, Dalseo-ku) of Taegu. Mean height of the children was increased by priority of Jung-ku, Dalseo-ku, Susung-ku and Nam-ku, and mean weight was of Jung-ku, Susung-ku, Dalseo-ku and Nam-ku. In food preference, boiled rice had the highest score of cooked rices in all of the different regions, jajangmyun had the highest score of noodles in Susung-ku, Jung-ku and Dalseo-ku. Cake had the hightest score of breads in Susung-ku and had significantly difference all the kind of other lesions. Songpyun had the highest score of rice cakes in all four regions. Jangjorim had the highest score of jorim foods in all four regions, but anchovy and green pepper jorim had the lowest. Toasted lavor and steamed chicken had the highest of toasted foods and steamed foods, respectively. Salads had the highest of muchimryu cooked potherbs and salads in all regions but kimchi and jangachi had low scores. Sujungkua had the lowest scores of beverages in all regions, but chocolate had the highest scores of cookies. In food intake satisfaction according to the regions, regularity, variety, hygiene, amount, and quantity of meal had the highest in dalseo-ku. Food temperature was highest in susung-ku. There was a direct correlation between type of housing and satisfaction in diversity of foods.

  • This study was conducted to estimate the safety level of non-cooking and cooking processed foods to propose the sanitary management of foods donated to foodbanks. The time and temperature were measured and the microbial levels of aerobic plate counts (APC), coliforms, E. coli, Salmonella spp., S. aureus, B. cereus, and E. coli O157:H7 were analyzed on ten food items donated to seven foodbanks. The amount of cooked foods donated to each foodbank was about 10 to 40 servings. All foodbanks hired a supervisor and had at least one refrigerator/freezer and one temperature-controlled vehicle, but only four foodbanks had the separate offices to manage the foodbank operation. The flow of donated foods was gone through the steps; production, meal service and holding at donator, collection by foodbank, transport (or holding after transport) and distribution to recipients. After production, the levels of APC of both non-cooking and cooking processed foods were complied with the standards by Ministry of Education & Human Resources Development, and were not increased till distribution. Only the level of coliforms in dried squid & cucumber salad (1.5×$10^3$ CFU/g) was not met the standards. E. coli and other pathogens were not detected in all tested samples. The microbial levels of delivery vessels and work tables were satisfactory, but the APC levels of two of four tested serving tables (6.9×$10^3$ and 5.3×$10^3$ CFU/100$cm^2$) and the coliforms level of one (1.1×$10^3$ CFU/100$cm^2$) were over the standards. The air-borne microflora level in serving room was estimated as satisfactory. It took about 3.0 to 6.5 hours from after-production to distribution and the temperatures of donated foods were exposed mostly to temperature danger zone, which had a high potential of microbial growth. These results imply that a checklist to monitor time and temperature in each step should be provided and the employees involving foodbank operation should be properly educated to ensure the safety of donated foods.

  • The purpose of this study is to suggest the menu patters of people in Kangbukgu for the basic data of the nutrition education program in its health center. The dietary intake was investigated by the 24-hour recall method for 488 subjects. To analyze patterns, dishes were classified into major staple food, kimchi, soup and side dishes and also classified into 24 categories by cooking method. Patterns by the kind of dishes for the subjects were cooked rice + soup + kimchi 〉noodle + kimchi > cooked rice + kimchi in the order of frequency of use. Patterns for breakfast were, cooked rice + soup + kimchi > coated rice + soup + two dishes of kimchi. For lunch, patterns were, noodle + kimchi > footed rice + kimchi = cooked rice + soup + kimchi. For dinner, patterns were, cooked rice + soup + kimchi = cooked rice + kimchi > noodle + kimchi. Results of analyzing by the number of dishes, were cooked rice + soup + kimchi + one side dish 〉cooked rice + soup + kimchi + two side dishes. It was significantly different by meal(p<0.01). The results of analyzing patterns for the main staple foods were cooked rice〉noodle > bread in that order. It was significantly different by meal(p<0.01). The results of analyzing patterns, with those considered basic food, cooked rice, soup and stew, were cooked rice + soup > cooked rice > cooked rice + stew. It was significantly different by meal(p < 0.01). With these results, the menu patterns of people in Kangbukgu were different by meal. The main dish was mostly cooked rice and the menu has the traditional menu patters, composed of cooked rice, soup and kimchi.
