This study aims to examine the effect of Genetically Modified ${\beta}$-Carotene Biofortified Rice rice developed by simultaneous expression technology in NAAS on biological immunity. Accordingly, this study added Genetically Modified ${\beta}$-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 ${\beta}$-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 ${\beta}$-Carotene Biofortified Rice can be seen as "safe" as this test result showed no big difference between general rice and Genetically Modified ${\beta}$-Carotene Biofortified Rice, and its usability is full of suggestions.

This study was conducted to evaluate the safety of ${\beta}$-carotene biofortified rice, a genetically modified organism (GMO) developed by Rural Development Administration. ${\beta}$-carotene biofortified rice were exposed on Sprague-Dawley rats for 13 weeks. All rats survived until the end of the exposure period. There were no biologically significant differences in body weight, feed and water consumption, weight gains and feed efficiency. There were no clinical signs of toxicity attributable to exposure to GM rice. Mild decreases in AST, ALT, TG levels were observed in Group II (25% GM rice (w/w) and Group III (50% GM rice (w/w), both in females and males. Results of histopathological changes treated with the ${\beta}$-carotene biofortified rice had no significant differences between the control and treatment groups. Based on these results, we deemed that genetically modified ${\beta}$-carotene biofortified rice was as safe as conventional rice.

The purpose of this study was to investigate antimicrobial, antioxidant, DPPH radical scavenging and SOD-like activity effect of Jubak(AFC) extract using hot water and ethanol solvent. All extracts from Jubak(AFC) had antimicrobial activities in the Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. Antioxidant activities of the Jubak(AFC) using soybean oil emulsion was confirmed to be higher in the extract using ethanol and hot water than control and the antioxidant was practically effective when concentration of the Jubak was 200 ppm. Scavenging effect of DPPH radical of Jubak extracts showed inhibition effect was above 80%. SOD-like activity were higher in hot water extracts than in ethanol extracts. If keeping up Jubak's study, it could have potential as a cosmetic raw material. Additionally, Jubak could be expected as functional material in food by different extract method.

Isotianil is a fungicide which has prevention effects against rice blast disease. In order to register this new pesticide, the series of toxicity data on animal testing were reviewed to evaluate its hazards to consumers and to determine its acceptable daily intake. Isotianil was almost excreted by urine and feces. It has low acute oral toxicity while has no skin toxicity and ocular irritation. Its skin sensitization was evaluated as slight. Genotoxicity of parent compound and metabolite was negligible. Chronic toxicity tests on rats and dogs showed changes of hematology, clinical biochemistry and liver weight. It had no reproductive and teratogenic effects. The estimation of Acceptable Daily Intake(ADI) is based on the lowest no-observed adverse effect level (NOAEL). The lowest NOAEL of 2.83 mg/kg bw/day was found in the twelve-months rats study. The NOAEL was based on increased liver weight and treatment-related effect on clinica chemistry finding at the nest higher dose level of 2.83 mg/kg bw/day. Therefore, it is considered appropriated to apply an uncertainty factor of 100 to the NOAEL 2.83 mg/kg bw/day from the rat study, resulting in an ADI of 0.028 mg/kg bw/day.

The global apple processing industry generates millions of tons of apple pomace (AP) annually, leading to significant environmental challenges owing to improper disposal methods, such as landfilling, which releases methane and other contaminants. This mini-review provides a concise overview of the strategies for the upcycling and circular resource utilization of AP. Upcycling strategies for AP can contribute to environmental protection through carbon reduction and resource circulation using existing resources in new methods instead of new materials. Additionally, this review presents the potential of AP as a raw material for food, pharmaceuticals, and cosmetics while examining the technical, economic, and environmental challenges and necessary improvements for its optimal use. Overall, the upcycling of AP offers a valuable opportunity to improve waste management and promote efficient resource utilization.

BACKGROUND: To investigate distribution and seasonal variation of concentration and flux of pesticides in Han river basin, water samples were examined at 24 sites in 2012 and 2014. METHODS AND RESULTS: Water samples were collected four times per year and subjected to liquid-liquid partition extraction followed by GC-ECD/NPD analysis. Of fifteen pesticides detected, iprobenfos, diazinon, isoprothiolane, endosulfan sulfate and oxadiazon were detected in a higher frequency, while fenoxanil, carbofuran, fenitrothion, butachlor and metolachlor were only detected in a sample. Pesticides with high occurrences, iprobenfos, diazinon, isoprothiolane, endosulfan sulfate and oxadiazon were detected in residue level of 0.01-0.46, 0.01-0.24, 0.03-0.85, 0.02-0.06 and 0.05-0.24 ㎍/L, respectively. Carbofuran and acetanilide herbicides were found at lower frequencies, but their concentrations were one order of magnitude higher than those of the others. CONCLUSION: Discharge of pesticides in downstream area were mainly contributed from rice farming and suburban horticulture, while pesticide occurrences in upstream area, such as Donggang river basin were caused by highland agriculture for cabbage and potato production. Despite the influx of pesticides from tributaries through intensive agriculture areas, pesticide concentration in the main stream water was low due to the dilution effect from the upstream. Therefore, the water quality was considered to be good at the most downstream, the effluent of Paldang dam.

To develop a new functional kimchi with cognition-enhancing properties, black Panax ginseng extract (0.5-5%, w/w) was added to a baechu kimchi preparation and the mixture stored at $4^{\circ}C$ for 30 days. Compared with control kimchi, the L values of ginseng-treated material were significantly decreased, but the a and b values were increased. The hardness value of ginseng-treated kimchi was significantly higher than that of control material from the $20^{th}$ day of storage. The edibility period of baechu kimchi treated with ginseng was prolonged by approximately 15 days compared with control kimchi. This resulted from decreases in the numbers of lactic acid bacteria and yeasts during the final stages of fermentation in ginseng-treated material. Inhibition of acetylcholinesterase activity by ginseng-treated kimchi was 2-fold higher than that of control material. A strong ginseng flavor and a bitter taste were evident in kimchi treated with 5% (w/w) ginseng, and sensory quality was thus decreased compared with control material. It was concluded that an appropriate concentration of black ginseng extract was 3% (w/w) in preparation of kimchi with a cognition-enhancing effect.

Novel food materials can be produced based on biotechnology such as genetic recombination, microbial fermentation, and enzymatic engineering by utilizing living organisms such as animal, plant, and microorganism or by applying the enzymes isolated from them. Especially, exploration and development of novel prebiotics and probiotics attracted great attention worldwide in the food industry, of which the research and industrial trends in food biotechnology field are promoting the production of next generation sweeteners and proliferation of beneficial bacteria in gastrointestinal tract. Development and commercialization of novel food materials by domestic bioprocessing technology have been sluggish due to the GMO/LMO food safety issues. Meanwhile, the US and EU do not perceive badly about gene manipulation technology, and the research is most active in the fields of crops and GMMs, respectively. Genetic scissors, which are considered as next generation technology, are notable since foreign genes do not remain in final products.
