In this study, we configured a system which ranks hazardous chemicals to determine their management priorities based on experts' opinions and the existing CRS (chemical ranking and scoring). Aggregate exposure of food, health functional food, oriental/herbal medicine and cosmetics have been taken into account to determine management priority. In this study, 25 hazardous chemicals were selected, such as cadmium, lead, mercury, and arsenic, etc. These 25 materials were ranked according to their 1) risk (exposure or hazard) indexes, 2) exposure source-based weight, and 3) public interests, which were also formed based on the existing priority ranking system. Cadmium was scored the highest (178.5) and bisphenol A the lowest (56.8). Ten materials -- cadmium, lead, mercury, arsenic, tar, acrylamide, benzopyrene, aluminium, benzene, and PAHs -- scored higher than 100. Eight materials -- aflatoxin, manganese, phthalate, chromium, nitrate/nitrite, ethylcarbamate, formaldehyde, and copper -- recorded scores in the range from 70 to 100. Also evaluated as potential risks were 7 materials; sulfur dioxide, ochratoxin, dioxins, PCBs, fumonisin, methyl mercury, and bisphenol A, and these materials were scored above 50. Then we compared risk index and correlation coefficient of total scores to confirm the validity of the total scores; we analyzed correlation coefficient of parameter and indicator. We discovered that the total score and weight, which has incorporated public interests, were high and statistically significant. In conclusion, the result of this study contributes to strengthening risk assessment and risk management of hazardous chemicals.

A simple and sensitive analytical method was developed using gas chromatography with electron capture detector (GC-ECD) and gas chromatography-mass spectrometry (GC-MS) for determination of Picoxystrobin in agricultural products (apple, hulled rice, mushroom, pepper, soybean, and mandarin). Picoxystrobin residues were extracted with acetonitrile, partitioned with saline water, and then they were cleaned up on a florisil solid-phase extraction (SPE) cartridge to obtain an extract suitable for analysis by GC-ECD and GC-MS. The method was validated using 6 agricultural product samples spiked with Picoxystrobin at different concentration levels (0.02, 0.05 and 0.5 mg/L). Average recoveries of Picoxystrobin (using each concentration three replicates) ranged 64.0~98.3% with relative standard deviations less than 10%, calibration solutions concentration in the range 0.1~5 mg/L, and limit of detection (LOD) and limit of quantification (LOQ) were 0.005 and 0.02 mg/L, respectively. The result showed that the developed analytical method is suitable for Picoxystrobin determination in agricultural products.

Food allergy refers to an immunologically mediated adverse reaction to food, mainly to proteinaceous constituents. Health implications vary between those individuals who experience mild physical discomforts to those with fast-acting, life-threatening anaphylactic reactions. The prevalence of food allergy is higher in children than in adults, estimated around 4-8% and 1-2% respectively in developed countries. Food allergy has no effective cure at the present time and total avoidance of causative foods is the most reliable prophylactic method currently recommended by the medical community. To help food allergic patients to make informed choices of their foods, mandatory labeling of selected food allergens has been introduced in several countries. All food allergen labelling provisions specify a set of allergens common to the regulated countries. Policy divergence, however, exists between countries by inclusion of additional allergens unique to specific countries and enforcement of specific labelling requirements. Such variations in food allergen labelling regulations make it difficult to manage allergen labeling in imported pre-packaged food products. This paper addresses two current issues in food allergen regulation: 1) an urgent need to determine true prevalence of food allergy in the Asia-Pacific region. This will enable refinement to the food allergen regulation to be more country-specific rather than simply adopting CODEX recommendations. 2) There is an urgent need for harmonization of food allergen regulation in order to prevent food allergen regulation becoming a trade barrier.

The objective of this study is to propose activation ways through an analysis on processing actual conditions and quality of farm food. For the analysis we have surveyed the actual condition of farms and conducted sensory test on farm food. Difficulties of farm business are in order to ‘preparation of papers’, ‘facility standard’, ‘improvement of quality’ and ‘labeling’. Overall, products from major food companies achieved better results than farm foods in all sensory test. It is necessary to educate the ‘Food Sanitation Act’ and prepare a manual for the development of farm food.

he purpose of this study is to offer youth with the basic materials for developing nutrition education programs and to help domestic science teachers in schools implement effective dietary education by examining their awareness of food additives. In the source of acquiring knowledges on food additives, the results were through mass media, technology and home economics teachers, and family members in order. The majority of students thought that they don't need the education about food additives. As effective teaching methods, they first selected the use of visual media, followed by experimental cooking classes, field trip, and inquiry lessons using processed foods. As a result of analyzing the education on food additives in accordance with demographic factors, more number of female students, compared to male students depicted the need for education on food additives. Further, the lower the cost students spend on purchasing processed foods per day, the higher the necessity of the education they indicate. The necessity of education content on food additives showed significant difference depending on the cost of buying processed foods, and the degree of interest and help real-life according to gender indicated significant differences. The satisfaction with education on food additives, which was implemented in home economics education revealed significant differences according to gender. This study aims to provide the basic data for the development and research of educational programs regarding good eating habits among the general youth. However, there are limitations to the presentation of the practical training program. For this reason, based on the results of this study, further studies should follow this study in order to develop and study educational programs related to food additives for teaching and learning purposes.

The purpose of this study is to determine the possibility of using Agarum cribrosum as a natural health food source.

Aroma compounds in sun-dried salt according to saltern material and packaging box were extracted by the headspace and were isolated by using GC-MS. These compounds were identified including ketones, heterocyclic compounds and six other compounds. Major aroma compounds in salts were identified as 4-methyl-2 pentanone, 5-methyl-3-hexanone, 4-methyl-3-penten-2-one, 2-hexanol, benzothiazole, 2, 4-bis(1, 1-dimethylethyl)-phenol, and 1, 3, 5 tri-tert-butyl benzene. However, we found no significant differences according to the saltern materials in three salts. Salts stored in Chamaceyparis obtusa (Sieb. et Zucc.) had more diverse aroma profiling than those in Pinus densiflora and Paulownia coreana. We consider that it need to research the development of high value added products for new aromatic salt.

The objective of this study is to investigate the sensory quality attributes for the development of soy sauce containing Cheongmirae (Smilax china) root. Aqueous extracts of Cheongmirae root and Cheongmirae-soy sauce were used for determining the antioxidant effect by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and sensory evaluation. Chengmirae-soy sauce was prepared by mixing Chengmiae extract (50%) and soy sauce (50%). Cheongmirae extract and Cheongmirae-soy sauce had strong DPPH scavenging effects, compared to that of general soy sauce. In sensory analysis, low intensities of smell, taste and overall preference were observed in Cheongmirae root extract. Various seasoning items, such as anchovy, dried-pollack, katsuobushi, shiitake, radish, and kelp, were used to determine the suitable type of soy sauce containing Cheongmirae root extract. The anchovy-kelp-radish and anchovy-shiitake kelp-radish among the seasoning items were well-matched with Cheongmirae root extract. From these results, soy sauce containing Cheongmirae root extract may be used as a soup seasoning for Korean style noodles.

Ohmic heating uses electric resistance heat which occurs equally and rapidly inside of food when electrical current is flown into. In other study, we researched about soybean protein’s characteristic changes by ohmic heating. Nevertheless treated same temperature, denaturation of soybean protein were accelerated by ohmic heating than conventional heating. In this time, we studied thermal property change of potato starch by ohmic heating besides conventional heating. For this purpose, potato starch was heated at same subgelatinization temperature by ohmic and conventional heating. And thermal properties were tested using DSC. Annealing of starch is heat treatment method that heated at 3～4% below the gelatinization point. DSC analysis results of this study, the T_o, T_p, T_c of potato starch levels were increased, whereas T_c～T_o was narrowed. This thermal property changes appear similar to annealing’s result. It is thought the results shown in this study, because the heating from below the gelatinization point. 6, 12, 24, 72, and 120 hours heating at 55℃ for potato starch, T_o, T_p, T_c values continue to increased with heating time increase. The gelatinization temperature of raw potato starch was 65.9℃ and the treated starch by conventional heating at 55℃ for 120 hr was 72℃, ohmic was 76℃. The gelatinization range of conventional (72 hr) was 10℃, ohmic was 8℃. In case of 24 hours heating at 45, 50, 55, 60, 65℃ for potato starch, the result was similar to before. T_o, T_p, T_c values continue to increased and gelatinization range narrowed with heating temperature increase. In case of conventional heating at 60℃, the results of gelatinization temperature and range were 70.1℃ and 9.1℃. And ohmic were 74.4℃ and 7.5℃. When viewed through the results of the above, the internal structure of starch heated by ohmic heating was found that the shift to a more stable form and to increase the homology of the starch internal structure.

In order to produce Hongkuk-ju, the production and characterization of Hongkuk (Monascus red koji) by Monascus anka KCTC 6121 were investigated. The optimum cultural conditions for the production of enzyme (α-amylase and glucoamylase) and pigment (yellow and red) from this strain on solid culture (steamed rice) were examined. The results showed that the production of α-amylase and glucoamylase reached the highest for 9 days and 8 days, respectively. Since then, the productions decreased slightly. The production of yellow and red pigments reached the highest for 8 days, decreasing slightly soon after. The optimal content of the initial moisture equally presented 30% in the enzyme and pigment production. After that, the enzyme production decreased slowly, whereas pigment production decreased sharply. The optimal temperature of the culture also showed 30℃ in the production of enzyme and pigment. It was found that the initial inoculum size in enzyme and pigment production was 10% and 20%, respectively. Under these optimal conditions, the production of monacolin K and citrinin was 74.35 ㎎/㎏ and 5 ㎎/㎏ for 12 days, respectively.

The purpose of this study was to compare the anthropometry, serum lipid levels, dietary behavior and health-related behaviors of shipbuilding workers. The education level was significantly higher in office workers than laborers, while age, monthly income and working years were not significantly different between both groups. The serum triglyceride, glucose concentration and AI were significantly higher in office workers than in laborers, but the serum LDL-cholesterol and HDL-cholesterol concentrations were significantly higher in laborers than in office workers. The frequency of breakfast and coffee intake was significantly higher in office workers than in laborers. In the office workers, age was positively correlated with systolic blood pressure but was negatively correlated with hemoglobin and hematocrit concentration In the laborers, working year was negatively correlated with hemoglobin, total cholesterol and serum LDL cholesterol concentrations. Exercise was negatively correlated with total cholesterol concentration, triglyceride and LDL-cholesterol concentration and AI in the office workers. The results of this study showed that office workers are more prone to related chronic degenerative diseases. Therefore, nutritional education for the provention of chronic degenerative diseases of shipbuilding workers needs to be more focused on improving the health status of office workers.

The purpose of this study was to lay emphasis on the importance of a restaurateur's role and qualities as well as to provide the restaurateur information necessary to effectively run a restaurant. To address the purpose, this study analyzed the qualities of a restaurateur and determined the influence they have on the business results, via conducting a survey with 117 restaurateurs from June 11th to June 26th 2011. In summary, male restaurateurs were higher in the vision directivity, desire to learn, accomplishment, challenge and pro-activity than their female counterparts, with a significant difference of p<0.05. According to their ages, the surveyees showed significant differences in the vision directivity (p<0.05), desire to learn (p<0.01), challenge (p<0.01) and pro-activity (p<0.01). In addition, also the survey revealed that the qualities of a restaurateur had a significant influence on financial performance, a sense of satisfaction and business results (p<0.001). The questionnaire resulted in the following: first, the vision directivity (p<0.05) and the challenge (p<0.05) affected the financial performance; second, the challenge had influence on the sense of satisfaction; and last, the vision directivity (p<0.05) and the challenge (p<0.05) had an effect on the business results. Thus, the study concluded that restaurateurs need two qualities: (i) the vision directivity in order to meet their goals and to have a higher business results and (ii) the challenge to try new managing methods in order to cope with the ever-changing environment.

This study was done to provide basic information about the storage and distribution of specialty grade coffee of which the market will be expanded through customer sensory evaluation according to the storage period of specialty grade coffee by the SCAA classified method with consideration to defective beans and scent. The specialty grade coffee sample of this study was extracted on day 1, day 14, and day 28. The water content showed a significant reduction on the 28th storage day and there was no pH change according to the storage period. Color degree was brightened according to the preservation period before and after grinding but there was no significant difference. The panels for sensory evaluation considered of 24 university. The sensory evaluation consist of aroma, bitterness, and astringency, acidity, aftertaste, overall satisfaction, and items for strength estimation consist of aroma, acidity and bitterness. The sensory evaluation was expressed by applying a 5 point Likert scale. The results showed that as the storage period increased so too did the aroma and the strength of bitterness. Preference was the highest on day 1 in every items except aroma and astrigency. However on day 14 and day 28, most of the sensory evaluation became low and then became high, which was inconsistent. Male students were not consistent in their evaluation according to the preservation period, but female students rated aroma and bitterness the lowest on preservation period day 1 and they prefer after a storage period of 1 day in regards to the entire degree of satisfaction including sour test. astrigency and aftertaste. The analysis of visiting frequency for coffee shops used demonstrated that the longer the preservation period, the lower the preference but was not significant in the case of involving a little frequency group. The group that did not like Americano coffee evaluated that the longer the preservation period, the lower the preference based on Americano coffee preference analysis. There was no consistency between the storage period day 14 and day 28 in strength and preference, but preference for storage period day 1 was high in every group, which means that the quality of coffee is affected by the preservation period.

We investigate the changes of fatty acids in blood for an evaluation of the effects of soft and enteric coated capsules containing omega 3 fatty acids. Fish oil, which contained 62.87 g/100 g of sum of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), was used as nutracueticals for omega 3 fatty acids. Lipid releasing amount in soft capsule was 70% in stomach condition. However, there was 10% of releasing amount of lipid observed in enteric coated capsule in stomach condition. In intestinal condition, 50% of lipid releasing amount in enteric coated capsule showed until 6 hr, but soft capsule until 90 min. EPA and DHA contents in soft capsule administration showed higher level than those in enteric coated capsule until 8 hr. However, the administration of enteric coated capsule showed higher level of EPA and DHA in blood after 8 hr. After 24 hr, mono-, poly-unsaturated and saturated fatty acids contents with enteric coated capsule showed higher level than those with soft capsule. The enteric coated capsule containing omega 3 fatty acids was expected to sustain omega 3 fatty acids.

In order to investigate the effects of 70% EtOH extract obtained from Hovenia dulcis Thunberg on enzymes relating reactive oxygen intermediate, cancer-stricken animals induced by DEN (N, N diethylnitrosamine) were recovered by administering the extract of Hovenia dulcis Thunberg. It showed that there was no effect on the generation of superoxide radical by the extract of Hovenia dulcis Thunberg. However, considering the increase of the activity of Cu, Zn-SOD and Mn-SOD in the tested animal class, the extract of Hovenia dulcis Thunberg could participate directly in removing of superoxides. The experimented-animals treated with the extract of Hovenia dulcis Thunberg showed an increase in the activity of the enzymes, catalase and glutathione peroxidase, which can eliminate hydrogen peroxide pertained in liver tissue. The extract of Hovenia dulcis Thunberg seemed to have some factors that accelerate the oxidation. Also, the extract of Hovenia dulcis Thunberg showed effects on the enzymes relating to the active oxygen toxicity which could be an indicator of aging and body toxicity.
