  • 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 purpose of the present study is to investigate the correlations between food intake behavior and job stress level and neuropeptide hormone concentrations. Job strain and food intake behavior were first identified using a self-reported questionnaire, concentrations of neuropeptide hormones (adiponectin, brain derived neurotrophic factor [BDNF], leptin, and ghrelin) were determined, and the correlations were analyzed. In the results, job strain showed significant correlations with adiponectin (odds ratio [OR], 1.220; 95% confidence interval [CI], 1.001~1.498; p < 0.05) and BDNF (OR, 0.793; 95% CI, 0.646~0.974; p < 0.05), and ghrelin exhibited a significant correlation with food intake score (OR, 0.911; 95% CI, 0.842~0.985, p < 0.05). These results suggest that job stress affects food intake regulation by altering the physiological concentrations of neuropeptide hormones as well as emotional status.

  • 식품 중 불법적으로 첨가된 부정유해물질을 규명하기 위하여 HPLC/PDA를 이용하여 인삼성분을 함유한 것으로 선전하는 식품 원료를 조사하였다. 발기부전치료제로 사용되는 실데나필의 변형체인 홍데나필과 유사한 구조를 갖는 미지물질이 확인되어 분취 크로마토그래피 등을 이용하여 불순물을 제거한 다음 HPLC/MS/MS, NMR 등의 기기를 이용하여 그 구조를 규명하였다. HPLC/MS 분석결과 미지 물질이 480 m/z의 분자량을 갖는 물질임을 확인하였으며 LC/MS/MS 분석 결과 실데나필에서 특징적으로 검출되는 m/z인 311, 339, 353이 확인되어 발기부전치료제와의 구조적 유사성을 확인할 수 있었다. NMR 분석 결과 미지물질은 홍데나필과 같이 sulfonyl 기가 acetyl기로 치환된 것을 확인 할 수 있었으며 실데나필의 에틸피페라진기가 옥소에틸피페라진기로 치환된 구조를 갖는 물질임을 확인하여 그 이름을 옥소홍데나필로 명명하였다.

  • This review discusses the status, antimicrobial mechanisms, application, and regulation of natural preservatives in livestock food systems. Conventional preservatives are synthetic chemical substances including nitrates/nitrites, sulfites, sodium benzoate, propyl gallate, and potassium sorbate. The use of artificial preservatives is being reconsidered because of concerns relating to headache, allergies, and cancer. As the demand for biopreservation in food systems has increased, new natural antimicrobial compounds of various origins are being developed, including plant-derived products (polyphenolics, essential oils, plant antimicrobial peptides (pAMPs)), animal-derived products (lysozymes, lactoperoxidase, lactoferrin, ovotransferrin, antimicrobial peptide (AMP), chitosan and others), and microbial metabolites (nisin, natamycin, pullulan, ε-polylysine, organic acid, and others). These natural preservatives act by inhibiting microbial cell walls/membranes, DNA/RNA replication and transcription, protein synthesis, and metabolism. Natural preservatives have been recognized for their safety; however, these substances can influence color, smell, and toxicity in large amounts while being effective as a food preservative. Therefore, to evaluate the safety and toxicity of natural preservatives, various trials including combinations of other substances or different food preservation systems, and capsulation have been performed. Natamycin and nisin are currently the only natural preservatives being regulated, and other natural preservatives will have to be legally regulated before their widespread use.

  • Safety of present food has been accepted on the basis of extensive use experience for a long time. Many food resources have been developed by traditional techniques without any significant adverse impacts on the safety of food. Recently recombinant DNA techniques are being used to develop new food resources. These techniques enable developers to make specific genetic modifications in food resources that introduce substances that could not be introduced by traditional methods. With these techniques food resources are being to resist pests and disease, to tolerate herbicides, and to have improved characteristics for food preservation and nutritional contents. Because the properties of an organism results from interaction between biochemical pathways controlled by many genes, the genes conferring these traits usually encode directly responsible proteins for the new trait as well as proteins that indirectly modify carbohydrates or lipids in food. Therefore, this kind of food is regarded as new food that has not been existed before, and the safety of the food developed by recombinant DNA techniques should be evaluated upon scientific basis. In this paper, the issues upon safety of the food developed by gene manipulation are diseased in terms of composional changes that can be introduced, potential food safety harzards that might arise, present status of safety regulations in various countries and international organizations, and suggestions for the safety regulation in Korea.
