The purpose of this study is to predict the economic size of foods-for-elderly market, which will be valuable information for establishing related policy and backup system. After setting the scope of related industry, detailed information for current market situation was investigated and a systematic forecast for market changes in the future was performed. Economic growth, changes in consumer expenditure and economic status of the elderly, current subscription of medical insurance and saving for pension were reflected. In addition, a survey toward related firms was completed and changes in aged population and incidence of chronic disease in the elderly were taken into account. Results show that the annual growth rate of the market was predicted to be the minimum 4.54% through the maximum 8.32% from 2010 to 2025 and its market size was forecasted to be the minimum 7,073 ten million won through the maximum 10,976 ten million won. It is expected that the market of foods-for-elderly will grow rapidly with development of foods technology and fast increase of aged population. Especially, growth of health functional foods and foods for special dietary uses for elderly will be distinguished. However, it seems that related firms are on the hedge, watching current trend of the related industry. This may results in insufficient supply against the demand. Therefore, policy for foods-for-elderly should be introduced and systematically administered, including R&D support, standardization and authentication for foods-for-elderly, construction of related database system.

A study was conducted to determine the dietary effects of Na-bentonite (NaB) and probiotics on meat characteristics and health of Hanwoo steers fed rice straw as a sole roughage source. A total of 24 growing Hanwoo steers (avg BW 232 kg) were assigned to two treatments which included a control diet (concentrate mix and rice straw) and a treatment diet (control diet + 0.5-1.0% NaB + 0.5-1.0% probiotics. The diets were fed for 22 months up to the time the animals were slaughtered. Dietary treatment increased (p<0.05) concentrations of trace minerals such as Zn, Cu, and Fe in the longissimus muscle compared to the control. The treatment diet did not affect cold carcass weight, yield traits such as backfat thickness, longissimus muscle area, yield index, yield grade and quality traits such as marbling score, meat color, fat color, texture, maturity and quality grade. Blood profiles of growing steers were within the normal ranges for healthy cattle. In conclusion, feeding a combination of clay mineral and probiotics to Hanwoo steers fed rice straw as a sole roughage source could have a desirable effect on improving trace mineral retention in longissimus muscle without any deleterious effects on carcass traits of steers.

This study focused on the yearly-dietary habits, nutrition status, and health of female students residing in Seoul. A number of classes were assess based on their dietary behaviors in oder to attempt to determine differences in their attitudes to nutrition, according to age. The students of class 2011 (sophomore) ate meals more regularly than the female students of the 2008 class (p<0.05). It was found that sophomore female students of class 2008 consumed higher than average nutrient intake. Sophomore female students of the 2011 class consumed lower than average vitamin B₂, C, Ca, and Fe intakes. Folic acid in take was lower than average in both groups. Phosphorus and sodium intakes in both groups were excessive (p<0.05). When surveyed, sophomore female students of the 2008 class believed that the most important thing for health was exercise, whereas students of class 2011 believed that nutrient intake was the most important factor (p<0.05). Female students of the 2008 class exercised 1～2 times a week generally, whereas students of class 2011 exercised three times (43.2%) (p<0.05). Therefore, it is necessary to study changes in dietary habits and health status according to the age of students, and develop specific nutrition education programs for female students.

This study investigated the effect of salt preference on dietary habits and the body composition of university students. The subjects were divided into two groups: 85 students who dislike salt (salt-dislike (SD) group) and 104 students who like salt (salt-like (SL) group). We found that the SL group showed a higher preference for sweet, sour, spicy, and bitter flavors compared to the SD group. There was no significant difference in the frequency of eating breakfast according to the salt taste preference. The meal speed of the SL group was significantly higher than the SD group (p〈0.01) and the body mass index of the SL group (22.59kg/m2) was higher than SD group (21.04kg/m2). The fat mass of the SL group (15.30 kg) was higher than the SD group (12.80 kg) (p〈0.01). Salt preference and snack intake frequency had a significant and positive correlation with fat mass. The frequency of eating breakfast, and meal speed also showed a significant and positive correlation with subcutaneous fat. In conclusion, the SL group eats relatively more, speedily and frequently intakes snacks and carbonated drinks, likely resulting in higher body and subcutaneous fat. These results suggest salt preference is related to food choice, influences unreasonable eating habits, and possibly changes body composition. Taste preferences should therefore be considered for dietary consulting and nutritional education.

This study was conducted to investigate the differences in households, parental perception, and dietary behaviors of preschool children from kindergartens with environment-friendly food service (environment-friendly food service group; EFG) versus children from kindergartens with general food service (general food service group; GFG). We sought this basic information to examine the impact of environment-friendly agricultural products in preschool food services. Age, education level, and monthly family income of the EFG were significantly higher than the GFG. The frequency of purchasing environment-friendly agricultural products was significantly higher in the EFG than the GFG, with the most frequently purchased items in both groups being vegetables. The GFG had a significantly higher perception than the EFG in the superior quality of environment-friendly agricultural products; however, a greater proportion of the GFG than the EFG thought environment-friendly products were too expensive. The most frequent reason for purchasing environment-friendly agricultural products in both groups was safety. When purchasing environment-friendly agricultural products, the most important selection factor for the majority of both groups was the label certifying quality assurance. Both groups also considered price reduction as essential for promoting environment-friendly agricultural products. In regard to parental perceptions on food service in kindergarten, the EFG had a significantly higher satisfaction with the nutritional adequacy of the menu compared to the GFG. Both groups considered food safety and health as primary reasons for using environment-friendly foods in the preschool food service, with a greater proportion of the EFG than the GFG responding this way. There were significant differences between the EFG and GFG, as the main satisfaction from using environment-friendly foods in the EFG was safety, freshness, and good hygiene, whereas the main satisfaction in the GFG was a good food service menu, freshness and good hygiene. Dietary behaviors of preschool children in the EFG were also significantly superior to the GFG. Thus, environment-friendly agricultural products have positive effects on the dietary behaviors of preschool children and should be increased in the preschool food service. Lowering prices and a strict supervision of quality assurance is also necessary to promote consumption of environment-friendly food materials.

The purpose of this study is to investigate factors influencing dietary satisfaction, and their perceived importance and performance, in North Korean refugees according to age. Questionnaires were completed by 220 North Korean refugees and data was analyzed with SPSS software. From our study we determined that fresh food, clean dishes, and proper vegetable oil are of high importance but considered poorly performed. 'Taste' and 'comfort' were factors with low importance but considered well-performed. The IPA technique proved that 8 items including Q4, Q5, Q6, Q7, Q8, Q9, Q11, Q13 were in 'Doing great, keep it up' and no items that got high importance and low performance were in 'Focus here'. North Korean refugees like Korean food more than Chinese, Japanese, and Western food. They specifically want to learn how to cook Korean casseroles, soups, and side dishes(e.g. Myeolchibokkum, Kongjorim). The North Korean refugees who resided in South Korea under a year have difficulties in understanding menus and Western table manners.

The purpose of this study was to investigate the dietary factors associated with characteristics of attention deficit hyperactivity disorder (ADHD) in upper-grade elementary school students. The study subjects were 397 students, and 52% of total study subjects were boys. The risk for developing ADHD was assessed by using a DSM-IV questionnaire. Boy's ADHD score was higher than that of girls (p<0.001). Subjects were divided into two groups according to the median of the ADHD score in boys and girls. The high ADHD score group showed higher frequency of skipping breakfast and a lower score for good dietary habits, as compared to the normal group. Further, the high ADHD score group showed higher frequency of processed food intake with lower frequency of vegetable intake, as compared to the normal group. These results suggest that undesirable eating habits and frequent intake of processed foods may be associated with higher risk of developing ADHD in elementary school students.

The purpose of this study was to develop children-friendly education materials based on food replicas for the dietary education of lower grade elementary students. Through a literature review on current dietary problems and dietary education for children, five education themes were chosen: balanced diet, seasonal food, traditional food, noodle culture, and making instant noodles. A total of 304 key food items for food replicas were selected based on the themes: six basic food groups (113 items), balanced meals (37 items), dietary habits (74 items), spring foods (13 items), summer foods (17 items), autumn foods (16 items), winter foods (11 items), Korean traditional foods (52 items), Korean native noodles (18 items), noodles from foreign countries (19 items), and making instant noodles (46 items). Next, a food replica database was developed consisting of name of the food, picture, size, ingredient, recipe, reference, and attached code. Powerpoint slides and teaching plans for all education themes were developed utilizing the food replicas in order to raise interest and understanding of serving size and intake amount. This research provides a basis for the development of food replicas as effective dietary education materials for elementary students and their use in extra-curricular activities, after school programs, community health centers, or food companies.

Probiotics, enzymes, organic acids, oligosaccharides, antioxidants, and other functional materials are actively being explored as alternatives to antibiotics. Probiotics include live beneficial microorganisms that colonize the intestinal tract and competitively inhibit attachment and growth of harmful microbes. Probiotics also increase feed efficiency by assisting in nutrient absorption and digestion. The current study was conducted in order to evaluate the effect of a new probiotic, CS-A, as a dietary supplement of a fermented product on growth performance, feed intake, and feed conversion efficiency in broiler chickens, and to evaluate its value as an alternative for antibiotics used as a feed additive. Antibacterial and anti-inflammatory effects of CS-A were investigated in vitro and the in vivo effects of a constant concentration of supplemented CS-A on growth rate and feed efficiency were evaluated. In addition, the safety of CS-A was assessed by examination of common symptoms and mortality. Determination of minimal inhibitory concentration revealed an excellent antibacterial effect of CS-A. Cytotoxicity was low and anti-inflammatory effects were achieved at the effective concentration of CS-A. Supplementation with 0.1% CS-A resulted in a feed efficiency score of 1.84 in broilers, compared to 2.00 in the control group. There were no adverse clinical findings, necropsy findings, hematology, and altered serum biochemistry parameters, and no mortality. Thus, it is concluded that CS-A is safe and effective as a feed additive.

This study was conducted to investigate the physicochemical properties of the ethanol extracts and soluble dietary fiber from Cassia tora L. seed. The proximate composition of Cassia tora, soluble solid contents, color intensity and contents of emodin and rhein of Cassia tora extract, molecular mass distribution, sugar contents and viscosity of soluble fiber from Cassia tora were analyzed. Cassia tora contains 12.6% of moisture, 5.2% of ash, 13.4% of crude protein, 7.2% of crude fat, 8.8% of insoluble fiber and 48.3% of soluble fiber. The effects of extract condition on soluble solid contents, color intensity and contents of emodin and rhein of Cassia tora extract were investigated. The soluble solid contents were higher in 70% or 50% ethanol extracts than those in 100% ethanol extracts and showed highest value in grind sample extracts. In Hunter's color value, 100% ethanol extracts and whole Cassia tora sample extracts were higher in L and b value, but on the contrary, were lower in a value, than those of the other. The highest emodin and rhein contents were observed in 70% and 50% ethanol extracts, respectively, and showed higher value in room temperature extracts than in heating extracts. The molecular mass of soluble fiber from Cassia tora seed was estimated by gel filtration chromatography. Most soluble fiber(80%) exhibited a molecular mass range of between 50～2000 kDa. The major sugars of soluble fiber from Cassia tora seed were identified as xylose, mannose and galactose. The apparent viscosity of 0.5% soluble fiber from Cassia tora seed was 33 mPas showing a higher value than pectin or xanthan gum.

This study aims to examine the effect of Genetically Modified β -Carotene Biofortified Rice rice developed by simultaneous expression technology in NAAS on biological immunity. Accordingly, this study added Genetically Modified β-Carotene Biofortified Rice 25, 50% and general rice 50% as control group into diet and provided rats with the prescribed feeds and then measured the contents of immunoglobulin and cytokine in blood. As a result, male and female IgM, IgE, male IgG1, female IgG2a and TNF-a, IL5 and IL12 showed no significant difference; male IgG2a tended to decrease dependently on the combined concentration of Genetically Modified β-Carotene Biofortified Rice; female IgG1 showed significance with control group, but its association with diet was not found. The higher the dietary mixing ratio, the more the male and female IFN-a and female IL-4 contents, regardless of rice variety, and it was found that female IL6 content decreased significantly, but its association with diet was not found. The risk of beta carotene-enriched rice into environment and human body has not been reported yet. The digestion of Genetically Modified β-Carotene Biofortified Rice can be seen as "safe" as this test result showed no big difference between general rice and Genetically Modified β-Carotene Biofortified Rice, and its usability is full of suggestions.

Lactose is a disaccharide consisting of a glucose and a galactose. Milk is a sole source of lactose in natural food. Lactase hydrolyzes lactose into glucose and galactose, which are absorbed in the intestine and utilized by the body. After weaning, lactase activity declines. Therefore, the majority of adults have hypolactasia. The prevalence is above 50% in South America, Africa, and Asia. A significant amount of lactose is consumed as cow milk-based food products. However, it has no special nutritional importance for adults, and it is suspected as a dietary risk factor for coronary heart disease (CHD) and ovarian cancer. The aim of this study is to review the evidence and to propose possible mechanisms regarding the relations between lactose intake and CHD and ovarian cancer. Epidemiological studies support the connection of lactose and CHD. Although several mechanisms for elucidation of this connection have been suggested, calcium theory is the most plausible. Galactose is known to be toxic to ovary. Galactose has been suggested to induce ovarian cancer through hypergonadotropic hypogonadism. Some epidemiological data support this but others do not. Consumption of lactose or galactose can induce CHD and ovarian cancer; however, more research will be needed in order to determine the relation between lactose and these diseases.

This study was conducted to examine the effect of dietary n-3/n-6 fatty acid (FA) ratio on in vitro dry matter digestibility (IVDMD), fermentation indices and FA profile. Rice bran was mixed with oil sources (cotton seed oil and linseed oil) to make the diets at 0.02, 0.29 and 0.61 of dietary n-3/n-6 FA ratio. These diets (0.5g) were placed into the incubation bottles with 40 ml of anaerobic culture medium, which contained rumen fluid and Van Soest medium at 1:2 ratio. Five replicates of each diet and two blanks were incubated at 39℃ for 48 hours. After incubation, the incubated contents were centrifuged. The residues were freeze-dried for DMD and FA analyses. The supernatant was used for pH, NH3-N and volatile fatty acid analyses. The concentrations of lactate (p<0.001) and iso-valerate (p<0.001) decreased linearly with increasing dietary n-3/n-6 FA ratio, but acetate concentration (p=0.056) and the ratio of acetate to propionate (p=0.005) was increased linearly. The concentrations of n-3, n-6 FA and the ratio of n-3/n-6 FA in residues increased (p<0.001) linearly with increasing dietary n-3/n-6 FA ratio, but C18:1n-9 FA concentration was decreased (p<0.001) linearly. With these results, it could affect fermentation characteristics and FA profile of rumen content by dietary n-3/n-6 FA ratio.

The purpose of this study was to provide basic information regarding desirable body image recognition by examining body image recognition 395 middle school students in the Chungnam area. The average age of the subjects was 13.7 years for boys and 12.6 for girls. Their average height and weight were 165.4 ㎝ and 57.1 ㎏ for boys, and 155.7 ㎝ and 48.8 ㎏ for girls. As for body shape, girls thought that they were overweight more often and wanted to lose weight compared to the boys. Over half of the respondents answered that their weight control efforts were not systematic such ad via professional counseling. Weight control by students was attempted by themselves in order to control their weight by skipping meals. Further, the subjects exhibit dietary behavioral problems such as overeating, skipping meals, unbalanced diet, and eating speed. In conclusion, correct body image recognition is needed and families and schools should make efforts to help students properly control their weight and adopt proper eating habits.

The aim of this study was to evaluate the status of consumption and consumer satisfaction of dietary fiber supplements. The survey was conducted using a self-recorded questionnaire developed to meet the purpose of this study. The characteristics of the subjects who have taken dietary fiber supplements in the past are as follows: distributions of socioeconomic variables showed that the highest-ranked group(the group that reported the highest consumption of dietary fiber supplements) was professionals with a college degree or higher degree. In addition, the highest-ranked group were the most healthy, nonsmokers and reported drinking habits of ‘1～2 times/week’. Regarding the health status of those surveyed, digestive disease and constipation were the most common complaints. The majority responded with ‘health concerns’ to the question that asked the reason for their purchase of the dietary fiber supplements. Three major places respondents could find dietary fiber supplements were ‘through the internet’, ‘the market’, ‘the pharmacy’ in descending order. The compositions of dietary fiber products varied. ‘konjac’, ‘cellulose’, ‘psyllium husks’ were the most popular components consumed by the subjects. The average duration of product consumption was less than one month. In terms of satisfaction levels(satisfaction was ranked from 1 to 5), ‘taste’ and ‘type’ scored the highest in satisfaction levels while ‘price’ ranked the lowest. When subjects were asked about self-awareness regarding the physiological efficacy of dietary fiber supplements, the responses were positive in ‘bowel movement’ and ‘weight loss’. Further research is required to improve the quality of dietary fiber supplements in order to assist consumers in selecting the appropriate products.

The objective of this research was to investigate the effect of dietary cottonseed meal (CSM) supplementation on carcass and meat quality characteristics of Hanwoo (Korean cattle) bulls. Twenty two months-old-Hanwoo bulls of eight heads (4 heads per treatments) were fed for 5 months on a diet with or without (control) CSM (500 g/head/day). The samples of M. longissimus dorsi from carcasses were used for the quality measurement. Dietary CSM supplementation did not affect the carcass traits of bulls and pH value, drip loss, water-holding capacity and fatty acid composition of beef loin. Crude protein and crude ash content of beef loin were significantly (p<0.05) higher in beef loin from bulls fed CSM than in the control. During storage of 5 days at 4℃, CIE a*, b*, C* and total color values were significantly (p<0.05) higher in beef loin from bulls fed CSM than in the control. Overall, the present results indicate that dietary CSM supplementation may improve the oxidation stability of Hanwoo beef loin.

This study was carried out to investigate the effect of wormwood meal addition on constituent of blood, and liver fatty acid in broiler chickens. Two-day old 25 male commercial broiler chicks were distributed to 5 treatments (wormwood meal levels ; T1 (1%), T2 (3%), T3 (5%), T4 (10%), and control (C)) for 5 weeks. Free fatty acids of liver were a little different among the treatments and the palmitic, stearic, oleic, and linoleic acids were occupied 92.5% of total free fatty acids. Hemoglobin and hematocrite concentration of blood were significantly decreased (p<0.05) as the levels of wormwood meal increased, and serum albumin concentration of broilers was little different between 0 week and 5 week experiments. Also serum cholesterol, phospholipid, total cholesterol, and triglyceride concentration of liver in broilers were little different during the 5 weeks experiment. Serum triglyceride concentration was significantly increased (p<0.05) as levels of wormwood meal increased. These results indicate that dietary wormwood meal addition has a little positive effect on increasing unsaturated fatty acid and decreasing saturated fatty acid.

쌀 가공식품 부산물의 효소 처리로 인한 단백질과 식이섬유, 색도의 차이는 시료에 따라 각각 다르게 나타났다. Gravimetric method와 Kjeldahl method 간에 단백질 함량의 차이가 조금씩 있는 것으로 확인 되었지만, 전체적으로 두 값의 패턴이 같은 것으로 보아 이 두 가지 단백질 측정 방법간에 유의성이 존재한다고 판단하였고, 두 값의 비교를 통해 단백질 함량의 변화를 더욱 자세히 비교 할 수 있었다. 주박의 경우 다른 효소보다 Termamyl이 단백질 함량을 높이는데 영향이 큰 것으로 나타났고, 효소를 혼합하였을 때 그 시너지 효과가 두드러졌다. 특히 세가지 효소를 모두 혼합하였을 경우 가장 좋은 시너지 효과를 나타냈다. 그러나 식이섬유의 경우 Termamyl 단일효소를 처리했을 경우가 식이섬유 함량을 높이는 데 가장 효과적인 것을 확인 할 수 있었으며, 탈지미강의 경우 역시 Termamyl이 가장 효율 적으로 나타났고 주박과 비슷한 패턴을 보여, 역시 혼합효소로 시너지 효과를 확인 할 수 있었다. 그러나 식이섬유 함량의 경우, Termamyl 처리를 했을 때 약한 증가 경향을 보인 반면, 다른 효소 처리로 인한 식이섬유 함량은 감소하는 경향을 나타냈다. 시럽박의 경우 초기 단백질 함량이 높아서 단백질 함량이 크게 증가하지 않았다. 최적의 효소라고 평가할 만한 효소를 찾을 수 없었고, 시너지 효과 역시 나타나지 않았다. 그러나 식이섬유의 경우 효소 처리로 인해 상당량이 증가하는 것으로 나타났다. 특히 Viscozyme 처리로 인한 식이섬유 함량은 큰 증가를 보였으나, 시너지 효과는 크게 나타나지 않았다.

본 실험은 호박분말 급여가 돈육의 품질 특성에 미치는 영향을 조사하기 위하여 평균 개시체중 64.5 kg인 총 20두의 3원 교잡종(Landrace×Yorkshire×Duroc)을 대상으로 호박분말 급여량을 0, 2, 5 및 7%로 처리구별 5두씩 공시하여 출하전 30일간 급여하였다. 호박분말 급여구에서 높은 수분 함량 및 조지방 함량을 나타내었다. 명도(lightness) 값은 처리구들 간 유의적인 차이가 나타나지 않았으나(p>0.05), 적색도(redness)는 2% 및 7% 호박분말 급여구가 대조구에 비해 유의적으로 높은 값을 나타내었다. 육즙 및 가열감량은 모든 처리구에서 유의적인 차이가 없었으나, 5% 호박분말 급여구에서 높은 pH 및 모든 호박분말 급여구에서 낮은 전단가 값을 나타내었다. 호박분말 급여구에서 대조구에 비해 낮은 콜레스테롤 함량을 보이며, 호박분말 급여수준이 증가할수록 콜레스테롤 함량이 감소하였다. 또한 호박분말 급여구에서 높은 myristic acid(C14:0) 함량을 보인 반면, 2% 및 5% 호박분말 급여구에서 높은 palmitoleic acid(C16:1) 함량 나타내었다. 따라서 호박분말 급여는 돈육의 사후 pH와 수분함량을 높이고, 전단가 및 콜레스테롤 함량을 감소시키는 등 돈육 품질을 개선시키는 것으로 나타났다.

Both iron-deficient and zinc-sufficient diets have been known to be associated with a decreased risk of colon cancer. We investigated that effect of dietary zinc on the formation of colonic aberrant crypt foci (ACF) induced by azoxymethane (AOM) followed by dextran sodium sulfate in iron-deficient mice. Five-week old ICR mice were acclimated for 1 week and fed on iron-deficient diet (4.50 ppm iron) with three different zinc levels (0.01, 0.1, and 1.0 ppm) for 12 weeks. The total number of aberrant crypt (AC) and ACF was measured in the colonic mucosa after methylene blue staining. The total ACF numbers of low Zn (LZn), medium Zn (MZn) and high Zn (HZn) diet groups were 10.00 ± 2.67, 8.78 ± 3.12, and 7.96 ± 2.44, respectively and there were no significant differences among the groups. However, the total AC numbers of HZn (27.07 ± 3.88) and MZn (26.39 ± 5.59) diet groups were significantly low compared to LZn (22.57 ± 5.09) diet group (p<0.01). Cytosolic SOD activity was the highest in LZn diet group. But thiobarbituric acid-reactive substances level in liver was also the highest in LZn diet group compared to other groups. There is no difference in cell proliferation in mucous membrane among the groups, while apoptotic positive cells were increased in the HZn diet group. The high zinc diet exhibited decreased β-catenin-stained areas on the mucous membrane of colon compared to the LZn or MZn diet group. These findings indicate that dietary zinc might exert a modulating effect on development of ACF/AC in the mice with iron-deficient status.
