  • Quality evaluation for food and agricultural products have always been one of the most elusive problems associated with the handling , processing and marketing in a food plant production. In order to detect physical foreign materials in food and agricultural products, non-destructive techniques have been developed for many years. Application of X-ray system to detect physical foreign materials in food and agricultural products could be considered to be a high potential method. Especially , it is impossible to detect internal physical foreign materials by visual inspections. In this study, it was tried to be applied for two different X-ray devices. Soft X-ray system with CdTe sensor and X-ray CT scanner were evaluated for advantage of the detection of non-meltallic foreign materials in food and agricultural products . Though the soft X-ray is not a high energy radiation, it is possible to detect small different density in a material. The CdTe sensor has a high resolution for t e soft X-ray energy region. The density characteristics of foods and foreign material were expressed region. The density characteristics of foods and foreign materials were expressed as a soft X-ray energy spectrum. The energy spectrum was analyzed by a personal computer with a multi-channel analyzer. X-ray CT scanner can provide visual image and analyze by three dimensional information inside food and agricultural products. The X-ray CT scanner using as a medical equipment was used to detect a foreign material. The density characteristics of food and foreign materials in food were tried to be detected by the threshold value on the basis of the CT numbers. The soft X-ray absorption characteristics for acrylin plates and distilled water were obtained and could be found the possibility of detecting a small physical foreign materials such as a plastic wrapping film , a stone and grasshopper in food and agricultural products.

  • The purpose of this study was to investigate basic data on the degree of parents' recognition and satisfaction with the use of environment-friendly agricultural products. The conclusions of this study are as follows. The survey on the use of environment-friendly products in households showed that 68.7% of the respondents used environment-friendly products at home. The frequency of purchasing organic products by household consumers showed that 25.1% of the respondents bought organic products one to two times per week. The most popular items of the environment-friendly agricultural products used were vegetables, comprising 63.9%. The households with more than 3,000,000 won of monthly income tended to consume more domestic livestock products (p < 0.05). In comparison to general agricultural products, environment-friendly agricultural products users showed higher satisfaction level with a better quality in term of safety, quality, nutrition, taste, appearance, diversity and price. The degree of satisfaction with safety was the highest ($3.8{\pm}0.68$), and price showed the lowest ($2.76{\pm}0.79$). The degree of parents' recognition of the governmental support for environment-friendly agricultural products showed that those who were aware of the supporting policy were 44.5%, but 55.5% of them didn't know about the fact that 46.6% of the respondents agreed that environment-friendly agricultural products should be used in more than 50% of the foods used for school food service. The respondents pointed out that vegetables (45%) sprayed with pesticide are the most urgent food item that need to be replaced by environment-friendly farm products.

  • Purpose - The number of consumers adopting a lifestyle of health and sustainability has recently increased with the rise of trends in healthy living. The size of the organic agricultural product market has also increased given that these consumers prefer consuming environmentally friendly products that promote family health. However, awareness of organic agricultural products remains insufficient because of the characteristics of the Korean organic agriculture system, which only focuses on food safety inspection. The object of this research is to suggest a policy approach to increase understanding and to expand the purchasing of organic agricultural products by analyzing the influence of customer recognition of such products on their willingness to repurchase. Research design, data, and methodology - This study used binomial logistic regression analysis with the aim of explaining the effects of consumers' socio-demographic characteristics, their awareness of the equivalence arrangement for organic food and of the abolishment of low-pesticide agricultural product certification, and their viewing of negative broadcasts about organic agricultural products on their repurchase intention of such products. A questionnaire survey was conducted with 655 respondents who were in their 20s, lived either in Seoul or in its metropolitan area, and had purchased organic agricultural products. Result - From the results of the analysis, the majority of the respondents recognized organic agricultural products, but they found their prices to be expensive. The majority of the respondents were also aware of the certification system and the reliability of organic agricultural products. However, the results indicate that efforts need to be made to recover consumer trust as many respondents stated that their trust levels in these products were low. In general, those purchasing organic agricultural products were satisfied, but those answering "very satisfied" were not in the majority. Binomial logistic regression analysis results revealed that repurchase intention decreased as consumers viewed a greater number of negative broadcasts about these products. On the other hand, repurchase intention increased as they became more aware of the abolishment of low-pesticide certification. Repurchase intention also increased as income increased, as the number of family members decreased, and when a consumer was a member of a consumer organization. In addition, the older the consumers were who watched the TV programs, the smaller the number of family members that were aware of the abolishment of low-pesticide agricultural product certification and, the higher the income of the consumers aware of organic equivalence arrangement, the greater their repurchase intention. Conclusion - External stimuli, such as negative TV programs on organic agricultural products and the abolishment of the low-pesticide agricultural product certification, relevant social issues and systems, influence consumer repurchase intention. To that end, positive environmental and ecological broadcasting about organic agricultural products would contribute to an increase in purchasing. Additionally, this could be used for promotion and marketing plans as the results indicate that trust in organic agricultural products would cause a positive repurchasing effect.

  • Purpose - This study aims to understand the brand marketing of agricultural products and redefine their status in South Korea by analyzing impacts on consumer buying behaviors. Research design, data, and methodology - Products, with independent variables, were divided into agricultural brand products and generic products. Dependent variables were limited to expanding sales of a specialty brand through consumer awareness, consumer buying behavior, and confidence in agricultural products' quality. Control variables were based on characteristics of products such as freshness, safety, quality, and their category. Moderating effects were examined on consumer characteristics, including income levels and age. Results - Consumers increasingly purchased agricultural brand products rather than generic agricultural products because of the general reliability of quality assurance. Conclusions - Large agricultural specialty stores have enhanced the perceptions of quality assurance, freshness, safety, and diversity. Through a critical analysis of the domestic consumer income levels and age, gender, and demographic factors, such as agricultural consumer buying behavior not affecting consumers' health and life, this study proposes positive changes in quality perception.

  • 본 연구는 취나물, 고춧잎, 열무를 대상으로 건조에 따른 procymidone, diazinon의 잔류량의 경시적 변화를 연구할 목적으로 수행되었다. 실내풍건 방법으로 건조하는 경우, procymidone, diazinon의 잔류량이 증가하지만 수분함량의 감량을 고려하여 보정하면 $10{\sim}83%$ 감소하였고, 열풍건조 방법으로 건조하는 경우도 농약 잔류량은 증가하여도 수분함량의 감량을 고려하여 보정하면 $44{\sim}71%$ 감소하였다. 이 결과에 의하면, 건조에 의하여, 수분 보정한 농약잔류량이 대부분 감소하므로 건조농산물을 판정함에 있어 단순히 신선농산물의 기준에서 수분함량의 감량을 고려하여 기준 적용할 것이 아니라 건조과정 중 농약잔류량에 영향을 미치는 여러 요인을 고려한 추가연구가 필요하다고 판단된다.

  • 펩타이드형 독소인 마이크로시스틴(microcystins, MCs)과 노둘라린(nodularin, NOD)은 남조류라고도 알려진 시아노박테리아에 의해 생성되는 2차 대사산물로, 독소에 오염된 물, 토양 및 비료를 사용함으로써 농산물 내에 축적되고 이를 사람이 섭취함으로써 건강상 위해가 발생할 수 있다. 최근 MCs과 NOD의 농산물 내 오염에 대한 관심이 대두되며 국내외에서 여러 분석법을 기반으로 농산물 내 오염 수준을 조사하고 있다. 하지만 아직까지 수행된 연구가 많지 않으며, 특히 펩타이드형 독소 중 MCs의 분석 연구에 치중되어 있거나 오염 취약 지역에서 재배한 농산물이 주로 오염도 조사에 사용되는 등 연구에 한계가 있으므로 MCs과 NOD의 관리를 위해서는 보다 많은 체계적인 연구가 필요할 것으로 생각된다. 본 연구에서는 체계적인 모니터링 및 안전관리의 기반을 마련하기 위해 MCs 및 NOD의 이화학적 특성, 독성, 분석법, 오염사례 및 관리현황에 대해 기술하였다.
