John Glenn, America's first man to eat anything in the near-weightless environment of Earth orbit, found the task of eating fairly easy. With improved packaging came improved food quality and menus. By the time of the Apollo Program, the quality and variety of food increased even further. Apollo astronauts were the first to have hot water, which made rehydrating foods easier and improved the food's taste. Thermostabilized pouches were also introduced on Apollo. The task of eating in space got a big boost in Skylab. It also had a food freezer and refrigerator a convenience offered by no other vehicle before or since. Two different food systems will be used for future long-duration missions to other planets, one for traveling to and from the distant body and one for use on the surface of the moon or Mars. The transit food system will be similar to the space station food system with the exception that products with three-to five-year shelf lives will be needed. Thus, this part of the trip will be similar to what occurs aboard space missions now. The surface food system, be it lunar or planetary, will be quite different. It will be similar to a vegetarian diet that someone could cook on Earth. Once crew members arrive on the surface and establish living quarters, they can start growing crops. Once the crops are processed into edible ingredients, cooking will be done in the spacecraft's galley to make the food items. Disposal of used food packaging will be an issue since there will be no Progress vehicles to send off and incinerate into the Earth's atmosphere. Packaging materials will be used that have less mass but sufficient barrier properties for oxygen and water to maintain shelf life as those now in use.

Purpose: This study aimed to investigate the association between steamed food intake and risk of metabolic syndrome (MetS) in Korean females. Methods: Using Ansan/Ansung data of Korean Genome and Epidemiology Study, general characteristics, nutritional intake and biochemical and anthropometric markers of a total of 4,056 females aged 40 to 69 years were analyzed. MetS was defined following National Cholesterol Education Program Adult Treatment Panel III with some minor modifications. Logistic regression models were established to present the association between steamed food intake and the risk of MetS. Levels of food and nutrient intake by the frequency of steamed food intake and MetS phenotype were analyzed using general linear models. Results: A total of 38.4% of females had MetS. Among them, 24.9% of females with MetS had steamed food more than 1-3 times per week, which reduced the risk for MetS by about 25% (95% confidence interval [CI], 0.650-0.865). However, such association was not evident when various lifestyle factors were considered in statistical models. In rural residents, the benefit of having more steamed food was observed (adjusted odds ratio: 0.747; 95% CI, 0.583-0.958). The frequency of steamed food intake was associated with various food and nutritional intakes. However, trends in those did not differ by MetS phenotype. Conclusion: Having steamed food more than 1-3 times per week may reduce the risk of MetS compared to those who had less steamed food in Korean females. This protective effect of steamed food intake may differ by lifestyle and environmental factors. Although a clear difference in food and nutritional intake was not observed in this study, steaming could be an effective cooking method for a healthy diet for disease prevention and management.

This study was conducted to evaluate sanitary managment practices of institutional foodservice employees in Daejeon and Chungnam areas, and to suggest a guideline for an effective safety & sanitary managment of the institutional foodservice. The subjects consist of 782 employees in 80 institutional foodservice, respectively. The collected data was processed using the SPSS V.10.0 package for descriptive analysis. The results of this study were summarized as follows. The employees were female(97.2%), over 41 age(68.1%), high school(51.0%), less than 1-5 years(52.8%) of total career in the institutional foodservice. Employment status was contract(64.2%) and cook's certification w3s not applicable(80.1%). The institutional foodservice was over 1,000 number(65.0%) of average serving per day and operations format was direct(69.6%) management and 11-20 number of employees for cooking were 58.2%. Employees(96.0%) were received sanitation training and 82.4% of them have been monthly educated. Sanitation training instructor was dietitian 91.6%. The rating of sanitary management practices was food handling 4.36/5.00, food products management 4.32/5.00, personal hygiene 4.31/5.00, equipments and tools handing 4.18/5.00. The employees, who were educated in the sanitation training, presented significantly higher rates of the sanitary management practices than of the uneducated employess. Therefore, the institutional foodservice operations will have to pay special attention to sanitation training program of the employees. The suitable methods of sanitation training must be developed to improve the practical use of sanitary management by employees and institutional foodservice. Also, to enhance these practices, it is necessary to establish the countermeasure to care for safety & sanitary management of the institutional foodservice.

This study was conducted on 4th and 5th grade elementary school students in Daegu, Korea for the purpose of promoting health and proper dietary habits. A children food safety education program was developed and its effects evaluated on 4th and 5th graders (3,932 students for 4th year, 4,438 students for 5th year) at 46 elementary schools, which were under the jurisdiction of the four educational bureaus of Daegu city. Education was conducted in accordance with an education design plan, of which there were two goals, including know the contents of 'special act on children's dietary life safety management' and 'practice proper hand-washing'. 'Special act on children's dietary life safety management' was explained, and the education curriculum included proper hand-washing for prevention of food poisoning, quality certification mark on children's favorite foods, harmful foods such as unsanitary and adulterated foods, and green food zone. Flash songs, PowerPoint, 'glitter burger' notice note, and banner were used as education media. It was found that the awareness level of items related to 'special act on children's dietary life safety management' increased significantly after education (p<0.001). 'Necessity of nutrition education and children's food safety' also increased significantly (p<0.05) after education. Lastly, children answered that they washed their hands more often after education (62.9%) than before (60.7%).

The purposes of this study were to survey the present situation of nutrition education in junior/senior high school, to analyze the difference between the favorite subjects on students and the existing subject done by dietitians on nutrition education, and then to identify the subjects of nutritional education for junior/senior high school students. Self-administered questionnaires were given to dietitians and students and 142 of the 200 dietitians (71.0%) and 479 of the 564 students (84.9%) responded to the questionnaire on the nutritional education. According to the survey results, 76.1 % of school dietitians currently were doing nutrition education for students while the other 23.9% didn't have such education programs even though they recognized the necessity strongly. The target of nutrition education was student rather than parents or teacher generally and the principal measuring method for nutrition education effect was change of plate waste and leftover'. It was found that significant difference in the collector and source of nutritional education information between junior and senior high school dietitians (p< .05) . About ninety-eight percentage of dietitians felt that nutrition education should keep pace with meal service and this meant that almost respondent recognized the necessity of nutrition education for students. Because the most serious one among operational problems of nutrition education program was lack of enough time owing to too many affairs as dietitian, junior and senior high schools should support so that dietitians would share enough time for nutrition education. And also, a gap was existed between actual and favorite subjects on nutrition education. Significant differences existed in the following subjects; 'basic concept of food and nutrition', 'disease and nutrition', 'food culture in the world', 'cooking and culinary art', 'food of the 24 divisions of the year in the lunar calendar', 'food waste and environmental issue', 'food habit and food behavior', 'exercise and nutrition' (p< .001) 'table manner', 'food and individual sanitation', 'recommended dietary allowance' (p < .01) and 'menu planning' (p< .05) .Finally, 24 subjects of nutritional education were selected based on the survey results. These subjects would be expected to be able to contribute the effective and interesting nutrition education program for junior and senior high school students.

A survey on sanitary management at 98 food service institutions located in Jeollabuk-Do were conducted. Food service institutions included 13 hospitals, 38 schools, 40 enterprises, and 7 others. The sterilization in boiling water was used for disinfection of tableware, spoon and chopsticks, and dish towel. Cooking kit, refrigerator, chopping board, and knife were sterilized with disinfectant. Frequency of sanitary training program on employees was 56.1% for 1 time/month, 12.2% for 2-3 times/month, and 11.3% for 1 time/week. Preparing ratio of defrosting, warehouse and rest room, and washing and sterilization diary were 73.8, 60.5, and 54.5%, respectively. However, checking ratio of environments (9.5%), personal sanitation (10.8%), and sanitary training program diary(8.4%) were low. Major obstacle factors on the introduction of Hazard analysis critical control point (HACCP) system into food service institutions were lack of equipment and facilities (54.1%) and lack of understanding and data on HACCP system (17.3%). Therefore, in order to reduce the outbreak of food-borne diseases increasing frequency, we estimated that the introduction of sanitary management system and the conversion of dietician' perception on sanitary managements in food service institutions were needed.

The purpose of this study was to investigate the dietary habits, the nutritional knowledge and the consumption patterns of convenience foods of 618 university students located in the Gwangju area, from November twentieth to November thirtieth, 2002. The subjects included 301 males (48.7%) and 317 females (51.3%). This survey was conducted using a self-administered questionnaire. The percentage of students who were underweight, normal and overweight based on their body mass index (BMI) was 3.7, 88.0 and 8.3 far the males, and 29, 71 and 0 for the females, respectively. Most students (73.8%) skipped breakfast. This was because of lack of time (65.1%) of the cases. Self-reported eating habit problems were eating irregular meal (52.4%), overeating (21%), prejudiced meal (12.4%) and skipping meal (7.4%). The type of favorite snack was biscuit (31.9%) and cup Ramyon (31.9%). The rates of alcohol drinking in male and female students were 88.0% and 85.8% respectively, and the rates of smoking were 35.9% and 28% respectively. Males ate fiequently cup Ramyon (2.08 $\pm$ 2.95), fries (pork cutlet, fried potato) (1.91 $\pm$ 2.58), Ramyon (1.81 $\pm$ 3.00) and kimbab (1.70 $\pm$ 3.17) more frequently, while females ate kimbab (2.25 $\pm$ 3.26), cup Ramyon (1.89 $\pm$ 2.09), fries (pork cutlet, fried potato) (1.77 $\pm$ 2.67), Ramyon (1.46 $\pm$ 1.1.95) and fish paste (1.45 $\pm$ 2.22) more frequently. The nutritional knowledge score was higher in females than in males. The mean consumption patterns of convenience foods of students living in home were lower than that of students living in dormitory and boarding w/cooking. When the amount of pocket money available and the body mass index increased and the nutritional knowledge level was low, the mean consumption of convenience foods increased. The mean consumption of convenience foods correlated negatively with nutritional knowledge (p < 0.01). Therefore, nutritional education for university students is needed so as to improve their health and nutritional education program should be developed to meet the various needs of these students.

The purpose of the study was to investigate the perception and the knowledge of the Korean traditional foods in elementary school students. For the investigation, 373 fifth-grade elementary school students in Incheon were surveyed by a questionnaire, and the data were analized by the SPSS 10.0 program. The result showed that 85% of the surveyed schoolchildren showed the interest in the Korean traditional foods. It also revealed that female students are more interested in the traditional food than male students and the children of the career woman are more interested than those of the housewives. As for the motive of their interest, 39.7% of the subjects answered 'through mass media'. Male students and the children of the housewives got the interest through their mother, and female students and the children of the career woman got the interest through their hobby of cooking food. Among the traditional foods, 76.4% of the children designated kimchi as the most proud traditional food. As for the reasons of reducing traditional food use, 39.9% of students responded because of 'not-tasty' and 28.7% of students replied because of 'not enough time to cook'. But 62.2% of the subjects thought the traditional foods should be more used in the future. As for the succession and development of the traditional foods, 33.8% of the subjects said it should be carried out by the family. The basic knowledge score of the traditional foods was 5.78 on a scale of 10, which showed relatively low level. The lower their basic knowledge, the less their interest in the traditional foods was. The samgyetang, ogokbap and bindaetteok were the most perceived traditional foods. The cheonggukjang, nabakgimchi and jindallaehwajeon were the foods they had seen, but the they didnot have heard or seen the others. Among the traditional foods, susugyeongdan, jindallaehwajeon and dasik were more perceived by the schoolchildren in the rural area than those in the urban area. The jindallaehwajeon and dasik were more perceived by female students than by male students. Therefore, in order to make elementary schoolchildren take the traditional foods with pride by increasing their perception and knowledge of them, the family should give them many opportunities to eat traditional foods. The school also should try to establish a cooperative relationship to the family of schoolchilderen and use more Korean traditional foods in the school's meal program. Furthermore, the society's concern and support are necessary and also the role of mass media, which have great influence on children, is important.

Objective: This research aims to explore the nutritional and bioactive peptide properties of goat meat taken from various primal cuts, including the breast, shoulder, rib, loin, and leg, to produce these bioactive peptides during in vitro gastrointestinal (GI) digestion and absorption. Methods: The goat meat from various primal cuts was obtained from Boer goats with an average carcass weight of 30±2 kg. The meat was collected within 3 h after slaughter and was stored at -80℃ until analysis. A comprehensive assessment encompassed various aspects, including the chemical composition, cooking properties, in vitro GI digestion, bioactive characteristics, and the bioavailability of the resulting peptides. Results: The findings indicate that the loin muscles contain the highest protein and essential amino acid composition. When the meats were cooked at 70℃ for 30 min, they exhibited distinct protein compositions and quantities in the sodium dodecyl sulfate-polyacrylamide gel electrophoresis profile, suggesting they served as different protein substrates during GI digestion. Subsequent in vitro simulated GI digestion revealed that the cooked shoulder and loin underwent the most significant hydrolysis during the intestinal phase, resulting in the strongest angiotensin-converting enzyme (ACE) and dipeptidyl peptidase-IV (DPP-IV) inhibition. Following in vitro GI peptide absorption using a Caco-2 cell monolayer, the GI peptide derived from the cooked loin demonstrated greater bioavailability and a higher degree of ACE and DPP-IV inhibition than the shoulder peptide. Conclusion: This study highlights the potential of goat meat, particularly cooked loin, as a functional meat source for protein, essential amino acids, and bioactive peptides during GI digestion and absorption. These peptides promise to play a role in preventing and treating metabolic diseases due to their dual inhibitory effects on ACE and DPP-IV.

The objective of this study was to investigate the relationship between measurements of color and water-holding capacity (WHC) in pork loin. A total of 419 pork loins were sampled from crossbred (Landrace$\times$Jeju native black pig) F2 pigs at a commercial slaughter house. Meat color measurements (CIE $L^*$, $a^*$, $b^*$), chroma ($C^*$) and hue angle (h) were measured with the Minolta Chromameter and WHC was measured by filter paper fluid, drip loss and cooking loss. Also pH, moisture content and crude fat content were measured at 24 hr postmortem. CIE $L^*$, $b^*$ and h values had positive correlation with drip loss (r=0.52, 0.42), but CIE $a^*$ and $C^*$ values were not related to drip loss. Results showed that CIE $L^*$, $b^*$, and h color system was better than CIE $L^*$, $a^*$, $b^*$ color system to predict WHC, especially drip loss. pH was negatively correlated to drip loss (-0.42) and CIE $L^*$ (-0.67). Although CIE $L^*$ and pH were correlated to drip loss, the accuracy of their estimates for drip loss was 27% and 17%, respectively. Consequently, it was confirmed that meat color and WHC were not perfectly related and suggested that CIE $L^*$, $b^*$, and h color space should not be used independently to predict WHC of pork loin.
