In 2007, due to the outcome of the Korea-U.S. FTA negotiations, the opportunities for American beef greatly increased and a serious change in the domestic dining market is expected. The market currently faces issues such as the settlement of the beef origin declaration policy and the fulfillment of customer needs on domestic and imported beef. The following are the summary of the results of the aforementioned research and analysis. First, the consumer awareness level of origin declarations was comparatively low. Second, the reason behind the propensity for imported beef was the comparatively cheaper price despite the lower taste quality, and it was determined that there is a high level of distrust on domestic beef sold in general restaurants. Third, domestic beef showed a high valuation in taste, safety and freshness, while imported beef showed results which were below average. Concluding from the above research results, a dining environment should be created where consumers can trust what they eat through settlement of an origin declaration policy, and more efforts should be put into fulfilling consumer needs for both domestic and imported beef.

In this study, the most preferred trans fatty acid analysis methods, AOAC 996.06 and the Korea Food and Drug Administration official method, were reviewed and modified to apply to dairy products and dairy products imported into the Republic of Korea for evaluating trans fatty acid (TFA) content. The Rose-Gottlieb method for total fat analysis was validated with accuracy and precision parameters by analyzing infant formula standard reference material provided by the National Institute for Standards and Technology. The accuracy and precision data satisfied the CODEX guidelines. TFAs were analyzed with a resolution of 1.5 for 45 min using the modified oven temperature program. This modified method was applied to 45 dairy products from 11 countries. Average TFA contents in these imported dairy products ranged from 0.1 to 5.4 g per 100 g product. The majority of dairy products imported into the Republic of Korea were cheeses. TFA contents in the cheeses were 0.1 to 2.4 g per 100 g cheese. TFA contents in other dairy products were 1.7 to 5.4 g per 100 g product. These TFAs content variations can be explained by the trans fatty acids naturally present in ruminant milk formed by bacterial bio-hydrogenation in the rumen of cows and the different vegetable fat used as ingredients in the final products.

In recent years, polyphenol-rich herbs, fruits and processed foods, which are made of plant origin, have attracted much attention due to their potential health benefits. Pomegranate (Punica granatum L.) is an important source of bioactive compounds and has been used to treat diseases because of its medicinal properties. This research was focused on characterizing Korea's national cultivar and a similar product from California, USA. To evaluate their bioactive compounds and pharmacological activities, their anti-oxidation and cancer inhibition properties, as well as their organic acid and free sugar contents, were investigated. The national cultivar had low total sugar and high organic acid contents, contrary to the imported product. The results showed that the peel of national cultivar had high polyphenol and ellagic acid contents compared to imported product. The free radical scavenging capacity was evaluated via 2,2-diphenyl-1-picrylhydrazyl (DPPH) and its positive correlation with the total polyphenol contents was found. The anti-cancer activity of methanol extracts revealed growth inhibition against the prostate cancer cell. These results signify that while pomegranate, national cultivar, is more sour than the imported product, its health benefits could be excellent. Also, the polyphenol compound content of the non-edible part (such as the peel and the seed) was higher than that of the juice. Thus, it is suggested that the byproduct of the juice extraction could be potentially used in other fields such as medicine or dietary agents.

Thirteen species of mealybugs were intercepted in quarantine at Korean ports of entry on plant materials from China over the past 9 years (2000-2009). Of these, Phenacoccus madeirensis Green has been newly reported in China through this study. This list and key are provided to assist in identifying intercepted specimens of mealybugs from China.

After Freer trade, it is increasing to import crops, aquatic products, and livestock which are produce in a foreign land. But it is affect negatively to trust relationships and markets of Jeju's goods because of breaking it out that foreign productions exchange domestic. We need to traceability system. Therefore, this paper designed and implemented the traceability system of black pigs using RFID. To enhance more the Jeju's fresh image, this proposed system is designed to manage all process which are breeding, butchery, industrial processes, and traceability of black pigs, a local speciality, using RFID tags. also the user can provide the traceability system which is using webs anywhen and anywhere. The results is to provide farm's income rise and to make for steady supply and guarantee the quality of Jeju's goods with FCS, FCG, HACCP quotation.

The purpose of this study was to compare the chemical properties of the bokbunja distributed in Korea with the content of the bioactive substance ellagic acid. The bokbunja was Rubus coreanus group and Rubus occidentalis group were compared, domestic bokbunja and import bokbunja were compared. In bokbunja, free sugar was 30.89 ± 0.7 mg/g of Rubus coreanus and 29.05 ± 0.87 mg/g of Rubus occidentalis. and 27.28 ± 7.4 mg/g of domestic bokbunja and 21.58 ± 6.73 mg/g of import bokbunja. The free amino acids was 4.50 ± 0.08 mg/g of Rubus coreanus and 5.05 ± 0.08 mg/g of Rubus occidentalis. and 4.13 ± 1.09 mg/g of domestic bokbunja and 3.75 ± 0.31 mg/g of import bokbunja. Validation of the ellagic acid method was confirmed by comparing the retention time and spectrum of the standard and extract using HPLC. The calibration curve (R²) showed linearity of 0.9999. As a result of analyzing the ellagic acid content of each extraction solvent, DMSO and methanol mixture extracts were high, and Rubus coreanus was 2.56 mg/g and Rubus occidentalis was 3.16 mg/g, which was not significantly different (p < 0.05) In addition, the ellagic acid content of domestic bokbunja and import bokbunja was 2.83 mg/g and 2.99 mg/g, which was not significantly different (p < 0.05).

This study was carried out to estimate the quality of Jeonbuk-originated brand rice by comparing with other domestic brand rices and imported market rices. Rice variety, "Ilmi" was a major portion of brand rices in Jeonbuk region, and in few portion, there were variety-mixed brands, Shindongjin, Kosihikari, and Hitomebore. Comparing the ratio of head rice of high-quality Jeonbukoriginated brand rice with other domestic brand rices were not significantly different. Head rice ratio and mechanical taste values were not significantly different between high-quality Jeonbuk-originated brand rice and the other domestic brand rices. The contents of protein, moisture, amylose of rice were also not significantly different between them. The quality of high-quality Jeonbuk-originated brand rice was as good as that of other domestic brand rices and had not changed it by period. The foreign rice imported from United States, Chinese (involved parboiled), Thailand and the domestic rice cultivated in Jeonbuk province were investigated. There could get difference on the major component related to palatability of rice as country in this study. Comparing with foreign rices. protein content of domestic rice (6.1%) was similar with that of United States, lower than those of Chinese and Thailand. The head rice ratio of the domestic rice was 92%, which was similar with those of Unite State and Chinese but the Chinese parboiled rice was completely cracked during processing. The setback viscosity of domestic rice related to retrogradation was lower than those of the imported rice except United States. The Ad (Adhesiveness / H(Hardness) ratio was higher in the domestic and United States rice.
