La consommation d’aliments biologiques et sa part relative dans le régime alimentaire n’ont été que peu étudiées. De même, les profils nutritionnels et de santé, les motivations et les pratiques de tels consommateurs ne sont que rarement décrits. L’objectif de cette thèse était d’étudier et de caractériser les profils des consommateurs de produits issus de l’agriculture biologique sur le plan nutritionnel, de la santé et des pratiques. Les données de la cohorte NutriNet-Santé incluant des adultes français ont été exploitées. Les résultats de cette thèse ont montré qu’une forte consommation de produits bio était associée à une meilleure qualité nutritionnelle globale du régime. Le régime des très forts consommateurs de bio était ainsi souvent caractérisé par une place importante donnée aux produits végétaux et aux produits complets en particulier. La mise en oeuvre d'une analyse typologique a mis en évidence une diversité de profils des consommateurs sur le plan nutritionnel d'une part et sur les modes de production d'autre part. Ces différents profils de consommateurs étaient marqués par des différences sur le plan des caractéristiques sociodémographiques, des modes de vie, des pratiques d’achat et des motivations d’achat. Par ailleurs, la probabilité de présenter le syndrome métabolique était plus faible chez les forts consommateurs de bio comparés aux faibles consommateurs. L’étude cas-témoins a montré chez les forts consommateurs de bio une teneur significativement plus faible de certains résidus de pesticides dans les urines (2-(diethylamino)-6-méthylpyrimidin-4-ol/one total, en DETP et DMTP et en 3-PBA). Les conclusions des premières analyses transversales sur les marqueurs de santé restent à confirmer dans des études prospectives. L’ensemble de ces travaux souligne la nécessité de considérer toutes les dimensions de l’alimentation (structure du régime et mode de production bio ou conventionnel) dans les futures études sur les potentiels effets de la consommation de bio sur la santé. Ces résultats plaident également pour l’intégration d’une diversité de profils de consommateurs lors de l’élaboration de stratégies visant à encourager les consommations alimentaires durables. / Few data are available regarding the contribution of organic foods to the diet. In addition, dietary patterns, nutritional and health status of organic food consumers have rarely been described. The objective of this thesis was to study the characteristics of different groups of organic food consumers in terms of nutritional intakes, health status and practices. Data of the cohort NutriNet-Santé including French adults were analysed. The results showed strong dietary behaviour correlates associated with high organic food consumption. Higher levels of organic food consumption were related to healthier dietary patterns. Dietary patterns of high organic food consumers were characterised by high consumption of plant-based products, and wholegrain products in particular. A cluster analysis has underlined a diversity of profiles of consumers in terms of dietary patterns and mode of food production. Disparities in sociodemographic and lifestyle patterns were observed across clusters. Furthermore, the probability of having the metabolic syndrome was lower among high organic food consumers. The case-control study showed significantly lower levels of some pesticide residues (2-(diethylamino)-6-methylpyrimidin-4-ol/one total, DETP, DMTP and 3-PBA) among high organic food consumers compared to low organic food consumers. Prospective studies are needed to confirm these findings. To accurately assess potential effects of consumption of organic products, future etiological studies need to take into consideration all components of the diet (dietary patterns as well as level of organic food consumption in the diet). These results highlight the importance of the integration of a diversity of consumers’ profiles when developing strategies aimed at promoting sustainable food practices.

This thesis consider the use of organic products in spa facilities in South Bohemian Region and assess a regional supply of organic food. Results were obtained through primary and secondary data. Secondary data was provided by the study of literature and the subsequent creation of a literature review. Primary data were obtained in a questionnaire survey and structured interviews.

The whole environment - The climate of the earth. Because of the technology innovation causes the problem on ecological environmental protection. The implementation of the agreement of Kyoto, Already alert environmental protection of people on the global village. The organic industry is to safeguard the ecology, environmental protection and industry good for health. This thesis does the discussion to the development overview of the industry, carrying on consumers will do the market survey to the cognition of the organic products, purchase motive and buying the consideration, etc., probe into the organic marketing strategy in the supermarket of food. This thesis is consumed by two group (buyer and unbuyer) is investigated and analysed, in accordance with the demographic parameter, motive of buying, buy the parameter of considering, carry on comparative analysis, and the characteristic that the supermarket thorough fare is bought does analysis, to probe into the organic food on the thorough fare in the supermarket, feasible marketing strategy, this research from the product category to the organic industry, maker, supplyer the production and marketing system arriving and is worthy of selling to investigate , understand the marketing overview of organic industry's supplier , distributor in depth. Two consuming groups investigated by this research, the difference had in accordance with the demographic parameter is compared, in the characteristic to the organic consuming groups, the education degree is relatively high, there is more age by 41~50 and 51~60, the sex is mostly women, the professional housewife is in the majority, secondly government employees and teachers, income medium-sized income, buy the motive and rely mainly on the fact that there is no agriculture chemical, pollution-free and will not be endangered oneself and family's body, two colony that buy all with authentication most important government, to of fine qualities to afford to buy. As to the thing that production ground, the seller's trust will facilitate the trade, not the buyer will relatively consider whether the cost-effective and price are rational. The system of producing and selling of the organic industry, different from the general industry, the persons who engage in at present rely mainly on popularizing the idea more, For example ecological environmental protection to make the clever equilibrium of people's body and mind, healthy, also some are that Buddhism group make for good fortune, joining and popularizing in will engineering way, it is an invisible maturity sense to pursue, the persons who engage in at present have a good prospect to the future development of the industry generally because people can contact the organic products , go to experience one's own impression actually, nonpoisonous and light all over, and then promote the quality of life.

Recently years environmental protect conscious have raised and the people who concern the healthy issue. Lead to the organic food industry has been developing rapidly in Taiwan. Owing to the organic food industry are getting more acceptable and lovely by customers, therefore, organic food industry direct residence channel enter into the market, due to the organic food selling increasingly to be the current developing in the future, and the brand mark of organic of the stores have increasing rapidly in recently years. The system of producing and selling of the organic industry, different from the general industry, the persons who engage in organic food industry at present promote idea mainly, therefore, the purpose of the study is to study the organic food industry development status, and try to adopt in-depth interview to study the motivation of the organic food industry and business model framework. For view point of the theory of the industry analysis and competitive strategy, intend to study the feature of the case company practical operation, and submit business model suggestion for researchers and managers reference. The study results as follows¡G ¡]1¡^Under the uncertain environment, the case company will modify the organization framework and the other functions in order to construct suitable business model. ¡]2¡^The case company adopts prospectors strategy to suitable for enter into new industry or business model. ¡]3¡^The case company adopts both of emergent strategy and intended strategy to modify business model and competitive strategy continuously and in order to response non-forecast environment.

Genetically Modified Organisms (GMOs) are plants or animals that have been produced using genetic insertion or deletion via technology (also called genetic engineering or GE). Merged DNA from different species creates combinations of plant, animal, bacteria and/or virus genes that cannot occur in nature or in traditional crossbreeding. Our goal was to determine the presence or absence of GMO markers in USDA Organic Certified and in Non-GMO Project food products. We investigated only corn or soy-based products that were purchased from many types of retailers. Our study was limited to products that contained a label for USDA organic certification and/or Non-GMO Verified Project. DNA from each product was extracted, tested for purity, and examined for specific markers denoting the presence of genetic modification. Modified DNA was amplified using PCR techniques and tested against standards on electrophoretic agarose gel. Based on these results, we detected evidence of genetic modification in 75% of soy and 83.3% of corn claiming USDA Organic Certification and 0% of soy and 100% of corn claiming Non-GMO Verified Certification.

The booming organic food industry has led to an increased complexity in the way in which organic foods are marketed. Consumers now encounter a multitude of reasons for why they should (or should not) purchase organic foods. This research examines the promotion of organic food from four different food companies (three grocery stores and a food delivery program) as a way to uncover the narratives used to describe and endorse organic food. With an analysis of website and in-store content from chain, organic and local companies, I have used previous research in the area of organic food discourse to identify themes within the selected content. This study concludes that while there are important commonalities among the narratives, it is not the organic food itself that these commonalities stem from, but rather the company context (company goals and values) that frame the promotional narratives. / Graduate

In this study, we argue the organic industry's move towards a more legal definition of organic production indicated a shift in the legitimating criteria in the organic agriculture institutional field, which can be observed through the analysis of the legitimating accounts of various actors. Prior to USDA certification, institutional actors in the organic food field largely relied upon the norms and values of its participants to maintain order. Legitimacy was based on the perception that a firm embodied a certain value set, which typically included opposition to large-scale commercial operations (DeLind, 2000; Drinkwater, 2009). To some, the introduction of federal standards signaled a replacement of the personal trust between consumer and producer, and an increased reliance on external policies mandated by federal certification (Guthman, 2000; 2004a; 2004b). This study explores the intricacies of the various actors' legitimating accounts during this time of a shifting institutional field. Central questions include: how do these actors adapt their legitimating accounts to the changing context? Is there a discernible pattern to their rhetoric, not only over time, but also in relation to the other contemporary legitimating accounts? And finally, if patterns are evident, can they provide insight into the dynamics of legitimating sources in this institutional field?

The diploma thesis deals with the issue of organic food, organic food market, their prices and trade margins. The main part of the thesis is a survey of the prices of selected organic foodstuffs, both at the level of the producers (purchase prices) and at the level of the traders (selling prices). The data are collected at various points of sales chains, specialized stores and e-shops within the South Bohemian Region, as well as by addressing manufacturers. The thesis monitors the margins of individual sales formats for selected commodities and then evaluates them from several points of view.

research of price aspects, motivations of consumers
