Although the South Korean organic food market is in the infancy compared to other industrialized countries, Korean consumers'interest in organic food and retail stores devoting space to organic products have been rapidly increasing. Despite the fact of organic food popularity, the term "organic" is interpreted differently by individuals. As opposed to the US, Japan and the EU where have operated an integrated organic food labelling system, Korea has adopted complex organic labelling systems regulated by several different government bodies. As a result, complicated food labelling standards make consumers confused when purchasing organic foods. Furthermore, in terms of country of origin (COO), it is argued by a lot of researchers that COO effects vary from product to product and from country to country; moreover, other informational cues such as brand and price can influence COO effects. In modern society, COO labelling has been complicated, due to the sourcing, manufacturing and market locations of merchandise spread over the world. Accordingly, the evaluation of COO effects has become complex. In order to examine these issues, a quantitative research was selected to classify the commonfeatures of organic food consumers and construct statistics such as the extent to which people are aware of organic food and COO labellingvia a questionnaire which took place in two cities in Korea with a cluster sample of 161 organic food purchasers. As for the data analysis, one-way analysis of variance (ANOVA), T-tests, bivariate crosstatulations with Cramer's V were conducted,depending on the characteristics of variables and the assumptions the research data need to fit. It has been concluded that in general, Korean organic consumers comprehend the term "organic"in a closer way to the general concept rather than technical term, thus people do not appreciate environmentally labels which include organic food labels, although marital status influence the degree of label awareness, regardless of gender, age, education level and so on. Regarding COO effects on organic food, home organic products were Korean consumers'first choice over those from industrialized countries and developing nations. Specifically, in processed organic product category, domestically cultivated and processed organic products were absolutely preferred to leading national brands produced with imported ingredients and international brands. However, due to a lack of checks of ingredients' COO, consumers tend to purchase a leading national organic food brand, believing that it is a pure organic food sourced domestically. As a consequence, this research has suggested some important managerial implications and future research directions. In order to prevent consumer confusion when buying organic foods, it should be noted that consumers do not comprehend the organic food certifications, due to complicated labelling systems for organic produce and processed organic foods. Therefore, government bodies related to organic food distribution have to know consumers' perception of organic food labels and the significance of customer-oriented labels and reestablish labelling standards. Similarly, public advertising should be followed to raise public awareness of the labelling to enable customers to have the correct information. In addition, not only international marketers but also domestic marketers need to understand COO images and also the influence COO of ingredients has on the image of an organic product.

Kimchi, a centuries-old Korean fermented food, has gained global popularity due to increased interest in Korean cuisine. However, little is known about the actual status of kimchi information provided by major foreign online encyclopedias. In this study, we analyzed the content and quality of kimchi information in major foreign online encyclopedias, such as Baidu Baike, Encyclopædia Britannica, Citizendium, and Wikipedia. Our results revealed that the kimchi information provided by these encyclopedias was often inaccurate or inadequate, despite kimchi being a fundamental part of Korean cuisine. The most common inaccuracies were related to the definition and origins of kimchi and its ingredients and preparation methods. Our findings highlight the need for more accurate and reliable information about kimchi in major foreign online encyclopedias. This is particularly important in the context of promoting Korean food culture and increasing international awareness of kimchi. To achieve this, the collaborative efforts of Korean food experts and online encyclopedias are needed to ensure the accurate representation of kimchi in these resources. In conclusion, our study shows that foreign online encyclopedias often contain incomplete, inaccurate information about kimchi. This shortcoming must be addressed to promote a more accurate and comprehensive understanding of kimchi and Korean cuisine.

Salicylate from plant foods and histamine from animal foods have been suggested to cause various food allergic symptoms. Salicylate regarded as one of the inducing agents f3r chronic urticaria and asthma in allergic patients was studied. There is much interest about the effects of salicylate in food allergy. It it recently suggested that the intake of salicylate from foods may have contributed to chronic urticaria and asthma. The purpose of this study is to analyze the salicylate content in various foods. 153 ingredients commonly used in Korean foods were analyzed by HPLC. Among the vegetables, chard(8.22$\mu\textrm{g}$/g), soybean sprout(5.13$\mu\textrm{g}$/g), perilla lean3.03$\mu\textrm{g}$/g), Chinese cabbage(2.25$\mu\textrm{g}$/g), carrot(2.16$\mu\textrm{g}$/g), and squash(1.33$\mu\textrm{g}$/g) con-rained higher amounts of salicylate as compared to other vegetables. Among fruits, oranges(5.13$\mu\textrm{g}$/g), grapefruits(2.90$\mu\textrm{g}$/g), and plums(1.65$\mu\textrm{g}$/g) contained the most. In animal foods, almost no salicylate was found except in chocolate milk(0.32$\mu\textrm{g}$/g). It was also found in black pepper(8.2$\mu\textrm{g}$/g), coffee(can)(5.00$\mu\textrm{g}$/g), mustard(4.16$\mu\textrm{g}$/g), curry powder(3.24$\mu\textrm{g}$/g), kochujang(2.37$\mu\textrm{g}$/g), cream powder(1.19$\mu\textrm{g}$/g), brown rice(1.04$\mu\textrm{g}$/g) and sesame oil(1.00$\mu\textrm{g}$/g). All information found in this study can be used as nutritional education materials in potentially allergic people for a prudent diet plan and can also provide proper dietary guidelines for these allergic patients.

Dietary fiber imparts both mutritional and functional properties to foods. This review deals with (1) the classification of dietary fiber, (2) the plant cell wall models, (3) the relations between structure and physicochemical and functional properties of dietary fiber and (4) the applications of dietary fiber in foods. Dietary fiber can be classified in terms of source, plant function, solubility, charge and topology. Plant cell wall models are presented to provide information on the interconnections of dietary fiber components which determines the content of soluble and insoluble dietary fiber content. In reality, physicochemical and functional properties of dietary fiber originate factors such as chemical constituents , charge, branching degree, conformation and etc. Dietary fibers possess a variety of functional properties in food systems, which thus make them useful in food application. In particular, rheology and gelation of water-soluble gums or hydrocolloids are discussed for their effects on food quality. A guideline s also listed for the gum selection to meet the best product requirements.

The objective of this study was to analyze labeling improvements and evaluate willingness to pay for health functional foods with a focus on the caution for intake. For this study, we conducted a survey on health functional food intake behavior, confirmation and improvements of cautions for intake. We assessed the willingness to pay for improvement of the caution for intake. Consumers anticipate improved immune function, and fatigue improvement after consumption of health functional foods. They mainly checked the function components related to efficacy and effectiveness, ingredients and their contents, ingestion amount and method, expiry date and best mode of storage, product name, and cautions associated with ingestion of health functional foods. They has been difficulties in obtaining sufficient caution information for intake from the current labeling method. Therefore, it is necessary to improve the labeling of caution for intake. The analysis indicated that about 5.14% of the respondents were willing to pay more if new labeling was introduces. However, there is still controversy over their safety, which is damaging to the consumers. Therefore, by providing consumers with accurate and detailed information on cautions for intake, it can contribute to securing safety and improving the quality of health functional foods.

The aim of this study was to forecast the future Health Functional Food (HFF) market trends of Korea by studied about policies and market situation in Japan. The HFF is a food that is given an additional health function. In contrast with traditional foods, the HFF has unique characteristics in that it can be produced under the political regulations. The market size of the HFF was growing gradually due to the increased of an aging population and consumer need for high quality and diversified foods. The reason why the HFF market in Japan grew up earlier than other countries, Japan was the first country that institutionalized the HFF policies. Therefore, in this paper, by examining the policies and the market situation of Japan through literatures, we forecasted upcoming political and market situational changes of Korea's HFF market. We noticed that consumers needs about the HFFs which diversified, confidently ensured safety and ingredients will increase. In this regard, the government will reorganize legislation in order to increase the confidence of the safety of HFFs. In addition, the market size of domestic HFFs which are produced by major food companies will grow.
