There are many possibilities that recycled papers adulterate contaminants during the process. The objective of this research was to evaluate safety of paper-based packaging materials for food, especially commercial pizza boxes in Korea. Ultimately, we compared recycled and non-recycled commercial paper packaging materials. This study was based on Korean Food and Drug Administration (KFDA) regulation. PCBs were measured by GC-ECD. Arsenic and lead were analyzed using an ICP-MS. Formaldehyde was determined by LC-MS. Fluorescent materials were detected by UV lamp. The result of this study shows that non-recycled paper packaging materials meets all the tested hygienic specifications for food packaging materials, whereas recycled paper-based paperboard box may be contaminated by fluorescent whitening agent. Though these results need to be further studied, it is recommended to avoid using recycled paper in direct contact with food when used in food packaging.

With the breathtaking stride beingmade in the field of biotechnology, biocatalyst research using genetically modified microorganism (GMM) is actively being pursued in food industry. However, domestic food and food additive regulation standards and the number of examination management examples currently used in industry is lacking significantly. Up till now, there are only 6 examples of domestic GMM examination and approval cases for food production purposes and furthermore they are limited to the production of functional sweeteners. Domestically, although GMM is developed as a processing aid (contained use), if they are used in the production of food, the safety of GMM, including environmental safety, is evaluated. Also the produced food or food additives using GMM need to be separately examined and approved as a novel food. On the other hand, imported products produced using GMM need to gain approval for the final product only. Thus the expense and the time to obtain regulatory approval is advantageous for imported products versus domestically produced products. This commentary is written to create the opportunity to reform the current domestic food GMM regulation by comparing and discussing domestic and foreign case analyses of safety evaluation of GMM and related regulations.

The purpose of this study was to investigate the effect of Schizandra chinensis extract on the serum and hepatic lipids inhyperlipidemic rats fed with high-fat diet. The Schizandra chinensis extract decreased significantly in total serum cholesterol, serum triacylglycerol and heptic triacylglycerol but not in the total hepatic cholesterol. The Schizandra chinensis extract also decreased in very low density lipoprotein increased by the highfat diet without affecting high density lipoprotein cholesterol. These results suggest that Schizandra chinensis extract may be benificial for the regulation of hyperlipidemia.

Antioxidative potentials of estrogen and genistein were compared by measuring the degree of protection against plasmid DNA strand breakage induced by peroxyl free radicals using the DNA strand scission assay with pBR322 DNA. Genistein decreased DNA strand breakage by AAPH radical treatment at the all of three concentrations tested (0.5, 1.0, 1.5 $\mu\textrm{g}$/$m\ell$) with the range of 89.5% to 99.6%.(omitted)

This paper evaluates the new food policy adopted by the European Union to enhance the food safety after the mad cow crisis occurred in 1990's. Newly introduced rules at the EU level are characterized by two features. Firstly, an important part of them have the form of Regulation which is a binding legislative to all member countries. Secondly, most of them are horizontally applied to the whole food industry, irrespective of their kinds of performance, hygiene or labelling. According to theoretical studies on this topic, any food safety regulation for solving adverse selection problem or reducing negative externality in food consumption should be fine-tuning depending on the concrete demand and costs conditions of the food sector concerned. In this theoretical perspective, the food safety laws introduced at EU level after mad cow crisis have been over-regulated for improving social welfare. The true motivation for the transfer of the policy competence on food safety to the Union level is political rather than economic. Our analysis with a political economic perspective shows that how the EU food regulations have been embraced not only by the governments of member countries, but also by diverse interest groups like food processor & distributors, consumers and agro-livestock groups, and that they have been used as protectionist purpose specially against non-member developing countries. Taking into account the fact that the basic aim to form the Union is to establish a single market to enhance economic efficiency at the Union level, the EU is required to adopt some policy actions to reduce negative effects of too restrictive food safety regulations.

The present study evaluates the immunomodulatory effect of Bifidobacterium longum KACC 91563 in murine primary splenocytes and macrophages. B. longum KACC 91563 regulated T- and B-cell proliferation and inhibited the Th1 (IL-2, IFN-γ)/Th2 (IL-4, IL-10) cytokine imbalance and immune cytokine production. Moreover, immunoglobulin E (IgE) levels were significantly lower after treatment with B. longum KACC 91563. These findings suggest that B. longum KACC 91563 could modulate the systemic immune system toward both IgE production and regulation of the Th1/Th2 balance.

Mycotoxins are a group of toxicants giving a risk potential to human health in connection with the daily food intake. Food commodities once contaminated with mycotoxins can not be detoxified by any economic means and prevention was suggested as the only measure. In order to minimize the economic loss and health hazard posed by mycotoxins and toxicoses, systematic and toxicological studies on the subject should be undertaken. Most reports in Korea were concentrated on the mycological studies of relatively easy techniques and the confirmation or quantitation of mycotoxins was rarely done. Research topics to be undertaken in future may be exemplifid below: (1) Establishing assay methods for individual or multi-residue of mycotoxins (2) Monitoring of mycotoxins for suspicious food or feed samples in Korea (3) Epidemiological survey of mycotoxicoses (4) Etiological survey of disease outbreaks associated with mycotoxins (5) Accumulation of testing method and data on the toxicity of mycotoxins (6) Legal regulation to control mycotoxins and development of their detoxification / elimination methods
