  • A nutritional quality and rancidity of marketed korean traditional foods were assessed. That is, basic chemical analysis were done in Galbi-tang, Sullung-tang, Pibimbap, Pulkogi and Naeng Myon. Ca and P for the Galbi-tang and Sulung-tang and vitamin C for the Pibimbap were analyzed. Chemical analysis were done in Gangjung 4, Sanja 1, Parksan 6, Yoomilkwa, 4 out of korean traditional cookies. Amounts of energy and protein in Galbi -tang and protein and Ca in Sullung -tang are more than the recommended allowance at ta meal. Amounts of Ca in Galbi-tang and energy in SUllung-tang are less than the recommended . The amounts of energy and protein in Pibimbap, Pullkigi and Naeng Myon Except protein in Pullkogi are short of the recommended at a meal. And amounts of vitamin C in Pibimbap are short of the recommended, too. The content of carbohydrate in Korean traditional cookies is the highest one comparing to others. Contents of crude fat in Gangjung Parksan and Dasik which are made up of sesame, black sesame and pine nuts are higher than that of other Korean traditional cookies. Acid value and peroxide value in all Gangjung, Yoomilkwan and Sanja except the peroxide value in one Sanja product, are not in the excess of standard of peroxide value and acid value. The standard are 600meq/kg and 3 for peroxide value and acid value respectively in oil treated foods.

  • The present study aimed at evaluating the intensity of Tifton 85 conditioning using a mower conditioner with free-swinging flail fingers and storage times on dehydration curve, fungi presence, nutritional value and in vitro digestibility of Tifton 85 bermudagrass hay dry matter (DM). The dehydration curve was determined in the whole plant for ten times until the baling. The zero time corresponded to the plant before cutting, which occurred at 11:00 and the other collections were carried out at 8:00, 10:00, 14:00, and 16:00. The experimental design was randomised blocks with two intensities of conditioning (high and low) and ten sampling times, with five replications. The high and low intensities related to adjusting the deflector plate of the free iron fingers (8 and 18 cm). In order to determine gas exchanges during Tifton 85 bermudagrass dehydration, there were evaluations of mature leaves, which were placed in the upper middle third of each branch before the cutting, at every hour for 4 hours. A portable gas analyser was used by an infrared IRGA (6400xt). The analysed variables were photosynthesis (A), stomatal conductance (gs), internal $CO_2$ concentration (Ci), transpiration (T), water use efficiency (WUE), and intrinsic water use efficiency (WUEi). In the second part of this study, the nutritional value of Tifton 85 hay was evaluated, so randomised blocks were designed in a split plot through time, with two treatments placed in the following plots: high and low intensity of cutting and five different time points as subplots: cutting (additional treatment), baling and after 30, 60, and 90 days of storage. Subsequently, fungi that were in green plants as well as hay were determined and samples were collected from the grass at the cutting period, during baling, and after 30, 60, and 90 days of storage. It was observed that Tifton 85 bermudagrass dehydration occurred within 49 hours, so this was considered the best time for drying hay. Gas exchanges were more intense before cutting, although after cutting they decreased until ceasing within 4 hours. The lowest values of acid detergent insoluble nitrogen were obtained with low conditioning intensity after 30 days of storage, 64.8 g/kg DM. The in vitro dry matter of Tifton 85 bermudagrass did not differ among the storage times or the conditioning intensities. There was no fungi present in the samples collected during the storage period up to 90 days after dehydration, with less than 30 colony forming units found on plate counting. The use of mower conditioners in different intensities of injury did not speed up the dehydration time of Tifton 85.

  • This study was performed to analyze children's perceptions and practice levels according to gender and obesity status using a dietary life safety index. A national survey was conducted on fifth grade children (n = 2,400), who were selected using three-stage stratified cluster sampling from 16 provinces. The average height was 144.8 cm, and weight was 38.8 kg. The average body mass index was 18.4 kg/$m^2$ and underweight, overweight, and obese children were identified using the 2009 KHNANES cutoff values, which were 5.3%, 10%, and 5.9%, respectively. The perception and practice scores for hand-washing prior to eating were high and the score for willing to buy at a clean store was also high. However, students answered that the hygiene level of food stores near the school was poor. More students skipped breakfast than lunch or dinner. The frequency scores for fruit and vegetables were significantly higher for girls than those for boys. Students had a good understanding of nutrition labeling but did not frequently check the label. Seventy-five percent of the students tried to avoid high calorie foods with low nutritional value, but only 40% had the appropriate knowledge about high calorie foods with low nutritional value. Girls had better dietary life perception and practice levels than those of boys. No differences in perception or practice levels were observed based on obesity status. Nutrition education on the importance of eating breakfast and having accurate knowledge on nutrition labeling and high calorie foods with low nutritional value is needed. Behavior-centered education should be implemented to improve the perceptions and practice level of student's dietary life.

  • Objective: This study was conducted to evaluate nutritional value and in situ degradability of fruit-vegetable byproducts and their feeding effects on performance of growing Hanwoo steers. Methods: Nutritional value and in situ degradability of cabbage, Chinese cabbage and fruit-vegetable byproducts were assessed. In vivo feeding trial was also performed for 12 weeks. Thirty-six growing steers were randomly allocated into three groups according to body weight (BW) and age in 12 pens (4 replications/treatment) and assigned to one of the three dietary treatments: control (byproduct 0%), FV-B (fruit-vegetable byproduct 20%), and CA-B (cabbage peel 15% plus Chinese cabbage peel 15%, total byproduct 30%). Results: The crude protein contents of cabbage, Chinese cabbage and fruit-vegetable byproducts were 18.69%, 20.20%, and 10.07%, respectively. Concentrations of neutral detergent fiber (NDF) were higher in cabbage (22.31%) and Chinese cabbage (28.83%) than fruit-vegetable (13.94%). Higher concentrations of non-fiber carbohydrate were observed for fruit-vegetable (66.72%) than cabbage (44.93%) and Chinese cabbage byproducts (24.69%). The effective degradability (ED) of both dry matter (DM) and NDF for fruit-vegetable byproduct (DM, 84.69%; NDF, 85.62%) was higher (p<0.05) than cabbage (DM, 68.47%; NDF, 55.97%) and Chinese cabbage byproducts (DM, 68.09%; NDF, 54.22%). The DM intake was not different among treatments because the amount of feed was kept constant according to the BW of growing steers to prevent overweight during the growing period. The average daily gain during the whole experimental period was not different among treatments (1.26, 1.25, and 1.34 kg/d for control, FV-B, and CA-B). The ED of both DM and NDF degradability of the total mixed ration (TMR) diets were very similar among treatments. Feed conversion ratio during the whole period showed no significant difference among treatments. Conclusion: This study demonstrates that fruit-vegetable and cabbage byproducts up to 20% and 30% (as fed basis), respectively can be included in TMR diets for growing beef cattle.

  • Goat milk production and processing is a dynamic and growing industry that is fundamental to the health of hundreds of millions of people worldwide and is recognized as an important contributor to many national economies. Goat milk has contributed significantly to the economic and nutritional quality of life in developing countries, particularly in the Mediterranean, the Middle East, Eastern Europe, and Latin America. Goat milk has played an important role in the health and nutrition of infants and the elderly, and is also known to be beneficial and therapeutic for people with milk allergies. The potential and value of the nutritional, health, and therapeutic effects of goat milk and specialized goat milk products are now attracting attention. Various products can be made from goat milk based on its chemical properties. In addition, special products such as hair, skin care, products, and cosmetics produced using goat milk have garnered more attention in recent years. Nevertheless, high quality products can only be made from good quality goat milk. Advanced technical treatments are necessary to produce high quality goat milk that meets consumer expectation of nutritional, hygienic, and good sensory products. Good taste has been a critical criterion when deciding to buy and consume goat milk and associated products. However, it may be possible to produce more value-added products that cater to the new trends in consumer needs and thus maintain economic sustainability of goat milk industry.

  • This study was performed to investigate the awareness of the value on milk and the consumption pattern on milk of elementary, middle and high school students. The subjects were 453 students(129 elementary, 129 middle, and 195 high school students) living in the Seoul area. The results were as follows. The students of this study demonstrated low levels of awareness of the value of milk. They had an awareness of the value of milk about 'convenience', 'healthful', 'safety', 'diversity', and 'useful for snack'. Most students reported drinking milk two to three times a week and 13.2% of students preferred flavored milk rather than plain milk. General preference for milk was significantly higher in elementary school students than in high school students(p<0.001). The degree of satisfaction on milk was significantly higher in elementary school students than in middle and high school students(p<0.001). The respondents answered that their source of information about milk was the mass media. Their source of information from school was very low. In order to increase the consumption of plain milk, milk nutritional education is necessary in schools.

  • This study conducted an exploratory factor analysis to examine how consumers' confidence on the local foods used at tasty farm eateries influence their purchase behaviors. The four factors of perception of local foods used at tasty farm eateries and the factors of consumer confidence and purchase behaviors were extracted for a reliability analysis, correlation analysis of variables, and simple and multiple regression analysis. The following are the findings: first, among the four factors of perception of local foods used at tasty farm eateries, safety, sociality and product value had statistically significant influences on consumer confidence, whereas regional economic value did not. In other words, safety referring to the nutritional value and sanitary safety of food ingredients used for the native foods at the tasty farm eateries, product value referring to the characteristics differentiated from general Korean cuisine, and sociality referring to the various related experiences for the interests in farm culture and local food, leads to consumer confidence, whereas regional economic value referring to farm household income, local job creation, and development of farm tourism does not. Second, consumer confidence had a statistically significant positive impact on consumers' purchase behaviors. Among the five principles of local foods, reliability is the most important factor. When consumers gain confidence on local food items and are satisfied with them, they make additional purchases and revisits. Therefore, confidence is a very important aspect for the loyalty and sustainability of business.

  • The purposes of this study were to examine school foodservice employees' awareness on dietitians' service leadership and to analyze the effects of the service leadership on employee attitudes (leader reliability, value correspondence, and leader satisfaction). Questionnaires were distributed to 208 school foodservice employees from November 2007 to January 2008. The results were as follows. First, in terms of the employees' perception on the dietitians' service leadership, service belief gained the highest score, followed by insight, attitude, and ability: the average score was 3.8 point. Second, the leader reliability and leader satisfaction scores perceived by the employees were over 3.8 point on average but the awareness on the value correspondence was 3.43 point. Third, among the service leadership factors, service belief (p<0.001) and insight (p<0.001) had positive effects on leader reliability. Also, service belief (p<0.01), service ability (p<0.001), and insight (p<0.01) had positive effects on value correspondence. Finally, service belief (p<0.001), service ability (p<0.05), and insight (p<0.001) had positive effects on leader satisfaction. Fourth, a hypothesis test using path analysis revealed that dietitians' service leadership produced positive effects on school foodservice employees' attitudes (leader reliability, value correspondence, and leader satisfaction). In conclusion, the service leadership of dietitians directly contributed to leader satisfaction, value correspondence, and leader reliability in school foodservice employees.

  • This study was performed to analyze the nutritional contents (calories, carbohydrate, protein, fat, sugar, sodium and potassium) of home meal replacements (HMRs) and assess the total nutritional value of these meals. The energy, carbohydrate and sodium contents were highest in fried rice, and the percentage of the daily value (%DV) was also higher than 50%. In all HMRs, the sodium Index of Nutritional Qualities (INQs) was higher than one, but all sugar INQs were lower than one. Most of the energy contribution of the carbohydrates in fried rice, spaghetti and tteokbokki exceeded the recommended range, whereas protein and fat values were mostly under the recommended range in one-dish type lunchboxes and tteokbokki respectively. When applying the nutritional labeling requirements for food, a difference of 31% above or below the labeling standard indicates that continuous monitoring is needed. These results suggest that HMRs contain high levels of sodium and appear to be nutritionally imbalanced in part.
