South Korea is the representative consumption country of herbal medicines and most of herbal medicines circulating in Korea have been importing from the developing countries of Southeast Asia such as China, Vietnam, Indonesia and so forth. Domestic hygiene and safety are continuously proposed because herbal medicines which are circulating have the possibility could remain contaminants or residues. Physicochemical contaminants such as heavy metals, persistent organic pollutants, radionucleosides, microbial toxins, biological contaminants such as microorganisms and animals, agrochemical residues such as pesticides, substances used for fumigation, antiviral agents, and solvent residues are classified as major contaminants and residues in herbal medicines from 2005 September WHO.$^{1)}$ Currently our administration have established a permission standard and the inspection criteria against the heavy metal, the residual pesticides and a residual sulfur dioxide. Furthermore our administration is continuously monitoring and conducting researches for the policies and their scientific ground against herbal medicines. But the appearances or discoveries of the harmful new species due to environmental and industrial developments are becoming social problems. Therefore it may be necessary to continuously consider and investigate regarding hereupon. Recently, the contamination of the mycotoxins against foods such as cereals, nuts and the powdered red pepper have developed and started became problematic issue, and possibility of contamination against the herbal medicine is proposed. And since populations who are using the herbal medicines very limited to several nations, recognition and researches about contamination of mycotoxins in herbal medicines are very insufficient. Therefore it will be need to more focus on the international regulation of quality control and safety for herbal medicines. Now on, we are going to introduce the importance, occurrence, characteristic properties, World-wide research trends and detoxification of aflatoxins, which is known as the most potent mutagen, carcinogen and teratogen mycotoxins.

Purpose: The growth of online commerce is now becoming a major threat and a new opportunity for retailers. Existing offline retailers struggle to cope with new online retailers' threats by utilizing offline infrastructure. Besides, online retailers expand their online strengths to offline sales by opening their offline stores. Many retailers are paying close attention to the O2O business and the resulting changes. Thus, this research focuses on the O2O business model and process that retailers can adopt. Research design, data and methodology: Considering the features of products that retailers sell, this paper divides O2O business process with the following criteria: delivery lead-time and delivery area. And This research uses the business model canvas to define the features of O2O commerce business process. This paper also uses nine key elements in the business model canvas for analyzing the structure of O2O commerce business. Results: This paper suggests the delivery model of retailers respond to offline customer orders and summarizes the following results. (1) Considering characteristics such as logistics process, delivery area, and product type, we define the features of O2O business models: wide-area (warehouse) based O2O business model, regional area (store) based O2O business model and time-separated O2O business model. (2) This study checks the availability of the business model through the business cases of O2O business models. (3) This study also analyzes the O2O business model of domestic retail companies by the factors defined in the business model canvas. Conclusions: Retailers can adopt the O2O business process to fit their business requirements and strategy. The online retailers who deal with normal consumer products mainly have the wide-area based O2O business model. The wide-area based O2O business model can be suitable for retailers who manage inventory centrally. The time-separated O2O business model can be a good solution for fresh food retailers to operate the logistics process efficiently. And to shorten the delivery lead-time of fresh foods, the regional area based O2O business model can be fit to the retailer that utilizes its offline logistics or sales infrastructure. It may be much more important for retailers to share the inventory information with other branches and to change the role of offline stores.

Kochujang, a fermented hot pepper soybean paste, is a spicy condiment mixed with red pepper, boiled rice and mold fermented soybean (as koji) which is then fermented for several months. It has unique taste of hot, sweet, salty and savory flavor by all mixed ingredients by fermentation, and is one of most famous Korean traditional foods. The scale of the kochujang industry is about 200 billion won in Korea, and 7.8 million dollars and 4,500 tons in exports. Although it is still not a large part of the food industry in Korea, the scale of soy products will increase because it is a major subsidiary food in our dietary life and has grown from a homemade to a mass produced product. Kochujang has the largest market in the scale of sales among fermented soybean products and has merit because of its domestic base and its ability to grow to an international market due to its unique fermented taste. In order to make kochujang an international food, it Is necessary to study the scientific development of kochujang and the diversity of products using kochujang that are fitted to the taste of people around the world. In addition, participation in various exhibitions and food fairs supported by the government should help to promote kochujang throughout the world. In addition, these should be actively supported by the related businesses. Red pepper, a major ingredient in kochujang, has been widely studied and shown to have a positive effect on the reduction of fat, on the strengthening of the immune system, and on active biological functions. A fermented spice like kochujang has been shown to be beneficial for the body due to the process of fermentation rather than from the red pepper itself. If we prove the various biological functions of kochujang with a particular taste and flavor, it will energize a new market. It is necessary for business to make a continuous effort supported fly the scientific world and by government policy, in order to introduce this traditional food to the world. In the present day, the kochujang market is now on a firm basis and has been activated in the field of its study. Now, it is possible to achieve the birth of a secondary international market by concentrating on these efforts.

Fermented soybean foods are an important component of the Korean diet. Eoyukjang is a type of traditional fermented soybean source. Microbial analysis of eoyukjang was conducted during the fermentation period in this study. Microorganisms isolated from eoyukjang were identified by biochemical tests and 16S rDNA sequencing. 17 different microorganisms, including bacteria, yeast, and fungi were detected in eoyukjang during the fermentation period. Even though Aspergillus participated in the early stage of fermentation of eoyukjang, Bacillus species and Saccharomyces cerevisiae were the major microzymes in eoyukjang throughout the maturation period. Eoyukjang is generally consumed after the boiling of the final sample. Therefore, the final sample of eoyukjang was boiled and analyzed. Our results showed that no vegetative microorganisms survived under the boiling conditions for eoyukjang. Fermented soybean products in the domestic market were also assessed for comparison with the results from eoyukjang. The total cell number of kanjang (soy sauce) samples was between 0 to 42 CFU/mL. The isolated microorganisms were identified as Bacillus species. All Bacillus isolates were not found to harbor the three enterotoxin-producing and emetic toxin-producing genes.

Competitive direct enzyme-linked immunosorbent assay(cdELISA) of aflatoxin $B_1$ ($AFB_1$) in deonjang(Korean-style soybean paste) and kochujang(fermented hot peppersoybean paste) and the level of $AFB_1$ in modern or traditional style deonjang and gochujang, produced in Korea, was surveyed by cdELISA. From the standard curve of the cdELISA, the detection limit of $AFB_1$ was 0.2 ng/m/. The average recovery of $AFB_1$ was 71.5% in the range of 1~100 ng/g after spiking $AFB_1$ into deonjang and it means that it could be possible to detect the $AFB_1$ in these range by the cdELISA in deonjang. Among the 30 kochujangs tested, no $AFB_1$ was detected in kochujangs. Among the 30 deonjangs, $AFB_1$ was detected in 6 ones in the range of 1.0~6.0 ng/g. The occurrence of $AFB_1$ in deonjang and kochujang tested in this study was less than the Korea Standard and Specification of aflatoxin in foods (10 ppb).

This study is to compare the differences in food quality between traditional Korean restaurants and Western-style restaurants, and then to identify the shortcomings as traditional Korean food prefered than western food. The object of this study is not only to provide the basic data of the domestic food service industry to enable the traditional food ingredients but also increase the sales produced in the farm and fishing economy. Western-style and traditional Korean restaurant food quality were subjected to an IPA analysis to understand the importance and satisfaction with each of them. The IPA analysis of Western-style restaurants and traditional Korean restaurants showed that using regional specialties ingredients, healthy food, and the number of dishes in a set menu were commonly included in the first quadrant. Menu planners of Korean restaurants in should consider the need to develop traditional food using regional ingredients prepared by a reputable chef from the region, and develop delicious healthy food using local specialties without artificial flavors. In addition, considering the demographic characteristics, the ideal food should target visitors in their 40s who with 300~400,000 to spend with friends or colleagues.

Purpose: This study examined the food composition of four raw and boiled domestic potato cultivars: Superior, Dejima, Bora Valley and Rose. Methods: Proximate composition (moisture, protein, ash, dietary fiber and fat), minerals (calcium, phosphorus, iron, potassium, sodium and magnesium) and vitamins (thiamine, riboflavin and niacin) were analyzed in the study. Results: In this study, it was observed that the moisture contents of raw and boiled Bora Valley potato were 83.74 g/100 g and 81.57 g/100 g, respectively, which was highest among the studied cultivars. The protein content of the raw and boiled Rose potato (12.23 g/100 g and 11.02 g/100 g) was higher than that of the other cultivars. Protein contents of boiled Bora Valley and Rose potatoes were significantly lower than those of their respective raw samples. The potassium, phosphorus and sodium contents of Bora Valley potato were 2,397.69 mg/100 g, 389.13 mg/100 g and 14.12 mg/100 g, respectively. In case of raw potato, the calcium, iron and magnesium contents of Dejima potato were 51.52 mg/100 g, 3.21 mg/100 g and 137.62 mg/100 g, respectively, which were the highest values among the tested potato cultivars. Total dietary fiber content of Dejima potato was 14.78 g/100 g, which was the highest level. The dietary fiber contents of four cultivars of potatoes were lower after boiling. Thiamine content was highest in the Bora Valley potato (0.43 mg/100 g). Riboflavin contents of the Rose potato was 0.35 mg/100 g, which was higher than that of the others. Conclusion: Overall, four cultivars of raw and boiled potatoes had enhanced food composition. Therefore, these potato cultivars are expected to be highly valuable food items for the development and application of functional foods.

For agriculture is very highly dependent on climate and weather condistions, global warming seems to have a great impact on it, including its productivity, cultivation condition, product quality, and optimum cultivation location. In this study, we adopted geographical information system (GIS) in order to investigate the changes of Korea's cultivation area which are caused by global warming, especially with the examples of such tropical and sub-tropical fruits as lemon, fig, kiwi, orange, pomegranate, and mandarin. In terms of GIS techniques, we utilized the interpolate function for temperature changes, surface analysis function for slope, and raster calculator. Currently, these fruits's cultivation areas are in Jeju island and southern part of Korea. But these areas will be expanded according as our GIS model assumes $3^{\circ}C$ and $4.5^{\circ}$ increases of average and lowest temperature by the global warming in Korea. Optimum cultivation areas of these six fruits have two patterns; one is expansion and the other is belt shape shift. From the results of the study, we call for an urgent need of Korea government's policy and farmers' reasonable responses about global warming, which will be able to give more opportunities and better foods to Korea society in general.

This study was conducted to develop an edible smoked egg by penetrating seasoning through pressurization without damaging the eggshell and to investigate the quality characteristics of the product. The lyophilized smoked egg consisted of 2.43% moisture, 4.11% crude ash, 46.08% crude protein, 40.85% crude fat and 6.53% hydrated carbon. The total content of polyphenol was 3.11 mg%, 35.70% saturated fatty acid and 64.30% unsaturated fatty acid. Major types of saturated fatty acids included palmitic acid (C16:0), stearic acid (C18:0) and lauric acid (C12:0), while major unsaturated fatty acids included oleic acid (C18:1) and linoleic acid (C18:2). Due to smoking of the egg, the eggshell is dark brown, the egg albumen, egg yolk and egg shell are darker than boiled eggs, and the value of a (redness) is higher than that of boiled eggs. Overall, smoked eggs were organically superior than boiled eggs because of their seasoning and smoke flavor. The results of this study are expected to further the development of processed foods using domestic eggs and improve the egg processing industry.

For this survey, PCR (polymerase chain reaction) testing was conducted using 14 species-specific primers to monitor the labeling of allergy-causing substances in various foods. Sixty samples from stationary stores near elementary schools and imported confectionery shops were tested, including snacks, candies, and chocolate. Allergens of milk, wheat, eggs, tomatoes, almonds and peanuts were detected in 30 cases (50.0%). In addition, many products were detected as either containing unlabeled substances or not showing allergen-related information and labeling in Korean. In order to ensure that consumers are able to purchase products safely and securely, a system for thorough guidance and monitoring of allergen-related labeling by domestic manufacturing and processing companies and import-related companies is required.
