Red ginseng is a widely used dietary supplement and medicinal herb, and there are so many forms of ginseng products including tea, extract, capsule and jelly. The purpose of the present study was to propose some amendments on ginsenoside content of red ginseng products in Korea. For this purpose, we analyzed red ginseng products for simultaneous determination of 26 ginsenosides by ultra performance liquid chromatography with diode array detector. Some developmental aspects of Korea's ginsenoside content standard regulations for red ginseng products are needed to be examined as follows : Firstly, we proposed that four ginsenosides ($Rb_1$, $Rg_1$, Rf and $Rg_3$) would be detected in red ginseng products. Secondly, in case of red ginseng extracts, the sum of $Rb_1$, $Rg_1$ and $Rg_3$ would be 4.0 mg/g. The two proposals are helpful to comprehensive evaluation of quality of red ginseng products. In conclusion, the scientific studies on amendment scheme of ginsenoside content standard regulation of red ginseng product are very important to fortify quality control.

This is the result of pesticide residue monitoring certified Good Agricultural Practice (GAP) by national agricultural cooperative federation (NACF) from 2009 to 2012. NACF evaluated simultaneously 283 pesticide multi-analysis method with GC (ECD, NPD) and HPLC. 6,590 agricultural products were analyzed in this period. As the results 1) detected 20.27% in 2009, 23.42% in 2010, 28.07% in 2011 and finally 31.75% in 2012, respectively. There was the total detected pesticide residue in the agricultural products. The violated ratio of agricultural products were 2.25% in 2009, 1.82% in 2010, 1.67% in 2011 and 3.47% in 2012, respectively. 13 pesticides went over the maximum residue limits (MRLs); carbendazim was the predominant violation. 40 pesticides; endosulfan was the predominant detected pesticide did not registered respectively crops in Korea. Most agricultural products that were under the MRLs met the safety standard, however agricultural products that contain neither registered nor set up MRL any level for example endosulfan in strawberry. Agricultural products that go over the MRLs with permitted pesticides, for example carbendazim in apple, are rejected. Because of these intricacies continual observation and evaluation will be need during GAP agricultural cultivation.

The Ministry of Agriculture, Food, and Rural Affairs is currently pushing forward policies targeting the Rural Convergence Industry initiative to incubate the front-runners of the '6th industry', to increase off-farm income, to create rural jobs for elderly, and to create women-based farms. As a result, in 2017, a total of 11,604 Rural Convergence Industries were in business, and the goods produced from those industries were diverse. However, the quality and safety of those products are not being checked and managed thoroughly, which has caused consumers to not trust products made from the Rural Convergence Industries. Through a survey and the ordering logit model, this study analyzed consumer perception of the safety and quality of goods from the Rural Convergence Industries. The analysis revealed that we must first raise awareness of the importance of rural agriculture areas and the products of the Rural Convergence Industries to uplift consumer perceptions regarding the products produced by the industries. The analysis also revealed that diverse points of distribution (sellers), education on the importance of rural and urban areas, and marketing Rural Convergence Industry products within suburban consumer populations are necessary to increase the consumption of these products.

This study aims to examine the structural relationship between consumers' health-related lifestyle. purchasing attitude and purchase intention in the rice-based bakery products market. Data were collected from 397 consumers in their 20 years old and more. Results showed that purchasing attitude positively affected nutrition, trends and taste, and it was a key variable in explaining the intention to purchase rice-based bakery products. Therefore, it is necessary to develop and cultivate rice flour varieties containing various nutrients and develop products by capturing the food trends among consumers to induce them to purchase rice-based bakery products. Purchasing attitude fully mediated the relationship between taste and purchase intention, which suggests that it is necessary to hold tasting or sampling events and carry out promotional activities for consumers to perceive that rice-based bakery products taste good, which may lead to positive purchasing attitude.

Objective: The objective was to evaluate the impact of different forms of iron including myoglobin, hemin, and ferric chloride on the quality of chicken breast meat. Methods: Chicken breast muscles were subjected to 1, 2, 3 mg/mL of FeCl₃, myoglobin and hemin treatment respectively, and the production of reactive oxygen species (ROS) and malondialdehyde, meat color, tenderness, water holding capacity and morphology of meat was evaluated. Results: Hemin was found to produce more ROS and induce greater extent of lipid oxidation than myoglobin and ferric chloride. However, it showed that hemin could significantly increase the redness and decrease the lightness of the muscle. Hemin was also shown to be prominent in improving water holding capacity of meat, maintaining a relatively higher level of the immobilized water from low-field nuclear magnetic resonance measurements. Morphology observation by hematoxylin-eosin staining further confirmed the results that hemin preserved the integrity of the muscle. Conclusion: The results indicated that hemin may have economic benefit for the industry based on its advantage in improving water holding capacity and quality of meat.

This study determined the removal ofrates for three types of pesticides which were spiked from Chonggak radish during the preparation of chonggak kimchi. When Chonggak radish (leaves) were brined with 10% salt solution and rinsed with water, the removal rate of the three pesticides was 43.8%, 41.9% and 89.8% for diazinon, diniconazole and dimethomorph, respectively. When Chonggak kimchi (leaves) were prepared and fermented for 4 weeks at 4℃, the removal rate of the three pesticides was 82.4%, 77.2% and 98.9% for diazinon, diniconazole and dimethomorph, respectively. Pesticide residues in chonggak radish (roots) were removed by up to 54.7-85.1% of initial concentration through brining and washing. During the fermentation of chonggak kimchi (roots) for 4 weeks at 4℃, the amount of pesticide residues was decreased by 94.0%, 91.8% and 90.0% of initial concentration for diazinon, diniconazole and dimethomorph, respectively. The highest relative removal rate by percentage for the three pesticides asreached 66.5% by salting chonggak radish (leaves). On the other hand, the highest relative removal rate by percentage of pesticides was shown during fermentation, reaching 51.8% and 55.8% for diazinon and diniconazole, respectively, in Chonggak kimchi (roots). As a result of examining the differences ofbetween the three pesticide removal rates rates according to temperature while fermentedduring fermentation of Chonggak kimchi with three pesticides for 4 weeks at 0℃ and 4℃, diazinon pesticide removal was has a high pesticide removal rate of 2.7-10.8% from fermented Chonggak kimchi (roots) at 4℃ compared to 0℃. In the other pesticides, the difference in removal rate of the pesticideresidual pesticides residues by aging temperature was found to be insignificant.
