Syfte: Meningen med studien är att bidra med en större förståelse och förhoppningsvis nya insikter om konsumtionen av lyxprodukter inom matbranschen genom att integrera redan existerande teori med empiriskt material. Syftet är att ur ett företagsperspektiv beskriva hur en förståelse för konsumententbeteende kring exklusiva matprodukter kan användas i marknadsföringen av dessa produkter.Studien riktar sig till människor, forskare samt organisationer som är intresserade av marknadsföring av lyxprodukter, men är även riktad till människor med intresse för nutidens konsumtion. Vidare motiveras studien ur ett etiskt perspektiv genom att belysa fenomenet kring dagens konsumtion och göra konsumenter medvetna om drivkrafterna bakom sitt beteende.Problemformulering: Hur kan företag som säljer exklusiva matprodukter använda förståelsen för konsumenternas beteende i sin marknadsföring? Vad kan vara bakgrunden till att konsumenter väljer att konsumera högkvalitativa och exklusiva matprodukter? Hur kan företag kategorisera in dessa konsumenter i olika konsumentgrupper? Var och vid vilka tillfällen väljer dessa konsumenter att konsumera exklusiva matprodukter?Metod: Studien är en kvalitativ studie där en kombinerad fall- och tvärsnittsstudie är genomförd. De data som samlats in och ligger till grund för studiens resultat och slutsats är genomförd genom litteraturstudier, intervjuer samt en frågeenkätundersökning. Företagsrespondenterna som medverkade i intervjuerna samt enkätundersökningen är verksamma inom branschen samt har en dokumenterad erfarenhet av exklusiva matprodukter.Resultat och slutsatser: Det finns olika anledningar till att konsumenter väljer att konsumera exklusiva matprodukter, det vi har kommit fram till är att alla konsumenter gör det av emotionella och självuttryckande värden som grundar sig i olika externa och interna ambitioner. Utefter våra resultat valde vi att dela in konsumenterna i fem olika grupper baserat på konsumentbeteende: traditionalisterna, matälskarna, prestigesökarna, trendsättarna samt de utåtriktade konsumenterna. Dessa olika konsumentgrupper väljer att konsumera exklusiva matprodukter vid olika tillfällen samt av olika emotionella eller självuttryckande anledningar. Marknadsföringen kan utifrån en förståelse för konsumenterna anpassas och utformas till olika konsumentgrupper, rikta sig till fler målgrupper och på det sättet förhoppningsvis göra marknadsföringen mer effektiv utifrån ett företagsperspektiv. / Purpose: The purpose of this study is to contribute to an understanding and hopefully new insights about the consumption of luxury goods within the food industry by integrating existing theory with empirical material. The purpose is that from a business perspective describe how an understanding of consumer behavior can be linked to the consumption of exclusive food products and how this can be used in a marketing perspective of these goods.The study is aimed to benefit people, researchers and organizations that are interested in marketing of luxury goods, but also to people interested in today’s consumption. From an ethical perspective, the study is motivated by illustrating the phenomenon of today’s consumption and making consumers aware about the forces behind their own behaviour. Research question: How can companies that offer exclusive food products use the understanding of consumer behavior in their marketing?What can be the underlying reasons for consumers choosing to consume high quality and exclusive food products? How can companies categorize these consumers in different customer groups? Where and in what occasions do these consumers consume exclusive food products?Methodology: The study is executed through a qualitative approach where a combined case and cross-sectional study is conducted. The material that has been gathered as the fundament of the papers results and conclusion is made through literature studies, interviews and a questionnaire survey. The respondents of both interviews and the questionnaire survey are people active in the business and have recognized experience from the food industry.Results and conclusions: There are various reasons why people choose to consume exclusive food products, what we have come to is that all consumers do this of emotional and self-expression values that are based on different internal and external ambitions. Based on the results we have gathered in this study we chose to divide the consumers in five different groups based on consumer behaviour: the traditionalists, food lovers, prestige seekers, trend-setters and the outward consumers. These different groups of consumers choose to consume exclusive food products at different times and by different emotional or self-expressing reasons. With an understanding of the consumers the marketing of these products can be adapted and designed for different consumer groups, be targeted to a broader audience and thus hopefully make the marketing more effective from a business perspective.

Childhood obesity is a major public health issue. Canada has one of the highest childhood obesity rates in the world. Food advertising and marketing have contributed to the rapid rise in childhood obesity. High energy and low nutrient foods have been promoted directly to children through attractive imagery on packages, including the use of popular cartoon characters. Children’s food packaging also features a range of nutrition information targeted at parents, including nutrition claims; however, there is relatively little research on the impact of these nutrition claims and the extent to which they may interact with child-friendly imagery to influence parents’ perception of food quality. The current study used a 2 x 2 experimental design to examine the effect of four front-of-package (FOP) nutrition information and four cartoon characters on parental perceptions of children’s food products. Participants consisted of 897 parents recruited across Canada through GMI, a market research company. Participants were over 18, had at least one child between ages 4-10 and the primary shopper of their household. Participants completed an online survey in July 2011. Participants were shown images of food products with or without cartoon characters and with or without FOP nutrition information and were asked to rate the food product on appeal, nutritional quality, intention to buy and willingness to pay. Participants were also asked to rate the FOP nutrition information on believability, ease of understanding and perceived effectiveness. Linear mixed modelling examined the influence of cartoon characters, FOP nutrition information and socio-demographic factors on these outcomes. Results indicated that cartoon characters increased product appeal and FOP nutrition information increased the perceived nutritional quality of food products with low nutritional value. No significant differences were observed for intention to buy or willingness to pay. There was no consistent pattern between socio-demographic factors and product rating outcomes. For FOP nutrition information ratings, Health Check and Source of Fibre were rated more believable, easier to understand and more effective overall than Sensible Solution and Given the Thumbs Up by Kids. Overall, the findings indicate that cartoon characters can increase the perceived appeal and FOP nutrition information can increase the perceived nutritional quality of food products with low nutritional value.

The main goal of this study is to investigate stimulus that can be used to increase consumers purchase intentions toward suboptimal food products. Consumers seem to have low preferences to buy fruits and vegetables with unusual appearance, products with damaged package and close to the expiration date, usually called suboptimal food products. However, rejection of suboptimal food is an important contributor to food waste levels. Interventions aimed at encouraging the purchase of suboptimal food are scarce, however needed. This study used the theory of normative influence to test the effect of both descriptive and injunctive norms on a product with an unusual appearance, a product with a reduced expiration date and a product with a damaged package. The first study tested different messages appeals to create a realistic norm in study 2. From this study, it was selected the social message appeal and the frequencies of purchase toward each product, using them in the messages as the prevalent norm The second study analysed the effect of injunctive and descriptive norms of purchase intentions toward suboptimal food and also tested the effect of environmental concern and food waste problem awareness. Results show that both environmental concern and food waste problem awareness impact purchase intentions toward suboptimal food. Additionally, appeals employing social norms proved to affect purchases intentions toward these products. However, this effect only occurred for the vegetable with an unusual appearance and the product with a package damaged. For the product with a reduced expiration date the norms had no effect. Moreover, for the product with an unusual appearance, food waste problem awareness mediated the effect of injunctive norm on purchase intentions. Based on the results, this study contributes to the theory of normative influences by showing that, in a general way, this theory is applied to food waste reduction issues, more specifically, with suboptimal food consumption. However, it is necessary to consider the type of sub-optimally and the context where the influence is applied. Additionally, was discussed how social norms can be used to tackle food waste and the implications for marketing and policy actions.

Assim, esta dissertação tem como objetivo investigar as revistas de divulgação, os livros didáticos e os rótulos de produtos alimentícios a fim de verificar os significados que tais artefatos vêm produzindo no que diz respeito às gordurastrans e o quanto eles produzem discursos com relação à alimentação e a saúde dos sujeitos. Este estudo fundamenta-se a partir do campo teórico dos Estudos culturais sob um viés pós- estruturalista, entendendo que as pedagogias que permeiam tais artefatos produzem os modos de ser e viver dos sujeitos, mostrando o quanto essas pedagogias modificam e instituem as identidades e as subjetividades. Percebemos que os conhecimentos apresentados pelos artefatos são produzidos em instituições autorizadas como universidades, institutos e agências, mas nem todos os conhecimentos são considerados válidos para compor os currículos desses artefatos estabelecendo algumas relações de poder na escolha dos temas que emergem dependendo da demanda econômica sóciocultural. Assim vamos entender que os enunciados que são apresentados pelas revistas, livros didáticos e rótulos de produtos alimentícios atrelados ao discurso da ciência regula, dita e prescreve os cuidados que os sujeitos devem ter com relação á alimentação e a saúde. / Based on numerous studies which have been conducted establishing a direct relationship between trans-fat consumption and high rates of cardiovascular disease, we realize the importance of this topic and its repercussion in various cultural artifacts. Therefore, the aim of this work is to investigate advertisement magazines, didactic books and labels of food products, to verify the meanings produced by these artifacts regard to trans-fat and how they produce speech in relation to food and health of the individuals. This study is based on the theoretical field of the cultural studies under a post-structuralist view, understanding that pedagogies permeating those artifacts produce ways of live and be of the individuals, demonstrating how these pedagogies modify and determine identities and subjectivities. We realize that the knowledge presented by the artifacts are produced in authorized institutions such as universities, institutes and agencies, but not all knowledge is considered valid to compose the curriculum of these artifacts, establishing some power relations in the choice of themes that emerge depending on the economic socio-cultural demand. Therefore we will understand that statements presented in advertisement magazines, didactic books and labels of food products linked to the speeches of science regulates, determines and prescribes the care that individuals should have regarding to food consumption and health.

<p>Predmet disertacije predstavlja istraživanje trži&scaron;ta organskih poljoprivredno-prehrambenih proizvoda i analiza mera za pobolj&scaron;anje proizvodnje i potro&scaron;nje istih u Republici Srbiji.&nbsp; Osnovni cilj istraživanja je sagledavanje trenutnog stanja na međunarodnom i domaćem trži&scaron;tu organskih poljoprivredno-prehrambenih proizvoda i ispitivanje i jasnije definisanje određenih grupacija i stavova potro&scaron;ača u vezi potro&scaron;nje istih.&nbsp; Za potrebe ovakvog cilja istraživane su navike potro&scaron;ača, mi&scaron;ljenja, motivi, iskustva i stavovi u vezi potro&scaron;nje organskih poljoprivredno-prehrambenih proizvoda u Republici Srbiji. Ovo istraživanje sprovedeno je da bi se utvrdile karakteristike trži&scaron;ta organskih proizvoda u Srbiji, stavovi, praksa i osobine različitih grupa potro&scaron;ača organskih prehrambenih proizvoda, kao i faktori koji utiču na kupovinu ovih proizvoda. Jedan deo istraživanja posvećen je i analizi kretanja proizvodnje i trži&scaron;ta hrane proizvedene u organskom sistemu proizvodnje u Evropskoj uniji i na globalnom nivou.&nbsp; Organska proizvodnja u odnosu na konvencionalnu poljoprivrednu proizvodnju ima čitav niz prednosti, naročito ukoliko se sektor posmatra iz ugla multifunkciolalnosti poljoprivredne proizvodnje. Multifunkcionalnost poljoprivrede ne mora da se posmatra samo sa aspekta trži&scaron;nih relacija, već čitavog niza drugih funkcija koje poljoprivreda, kao delatnost, ostvaruje u ruralnim područjima. Proizvodnja organskih poljoprivredno-prehrambenih proizvoda u svetu u konstantnom je porastu jer je u svetu evidentan značajan rast u povr&scaron;inama pod organskom proizvodnjom. Promet organskih poljoprivredno-prehrambenih proizvoda, očekivano, uglavnom raste u zemljama sa vi&scaron;om kupovnom moći, ekolo&scaron;kom i prehrambeno-zdravstvenom sve&scaron;ću i navikama proizvođača. U isto vreme, značajno raste i tražnja za ovakvom vrstom poljoprivredno-prehrambenih proizvoda.&nbsp; Republika Srbija poseduje značajne potencijale za proizvodnju organskih poljoprivrednoprehrambenih proizvoda. Mogu se istaći prirodni potencijali, svest o potrebi za kvalitetom u mnogim industrijskim granama; velike povr&scaron;ine poljoprivrednog zemlji&scaron;ta koje nisu zagađene niti intenzivno obrađivane, &scaron;to ubrzava i olak&scaron;ava konverziju; pozitivan stav o organskoj poljoprivredi među akademskim osobljem, mnogim poljoprivrednicima i potro&scaron;ačima kao i ugovori o slobodnoj trgovini (EFTA, CEFTA, Ruska federacija, Belorusija, Turska).&nbsp; Ipak, u Srbiji postoji nedovoljan nivo obrazovanja u oblasti organske proizvodnje, nepovoljna struktura poljoprivrednih gazdinstava (veliki broj malih gazdinstava koja međusobno ne sarađuju; visoka prosečna starost farmera; tradicionalan pristup u proizvodnji; kriza stočarskog sektora), ali i neadekvatna primena ekolo&scaron;kog marketinga, nedovoljno svesni i informisani potro&scaron;ači, na jednoj strani i nedovoljno &scaron;irok asortiman, količina proizvoda i stalnost u ponudi, na drugoj strani. Trži&scaron;te organskih prehrambenih proizvoda karakteri&scaron;e uglavnom niska kupovna moć stanovni&scaron;tva, nedovoljna informisanost potro&scaron;ača i niska ekolo&scaron;ka svest stanovni&scaron;tva u Srbiji.</p> / <p>The subject of the dissertation is the research of the market of organic agricultural food products and the analysis of the measures for improving the production and consumption of these products in the Republic of Serbia. The main goal of the research is to gain insight into the current situation in the international and domestic market of organic agricultural food products and to examine and more clearly define certain consumers&rsquo; groups and attitudes related to the consumption of these products. In order to achieve this research goal, the dissertation examined consumers&#39; habits, opinions, motives, experiences and attitudes regarding the consumption of organic agricultural food products in the Republic of Serbia. This research was conducted to determine the characteristics of the market of organic products in Serbia, the attitudes, practices and features of different groups of organic food consumers, as well as the factors that influence the purchase of these products. One part of the research is devoted to the analysis of the trends in the production and the market of the food produced in the organic production system in the European Union and the world. Compared to conventional agricultural production, organic production has a number of advantages, especially if the sector is viewed from the perspective of multifunctionality of agricultural production. Multifunctionality of agriculture does not have to be viewed only from the point of view of market relations, but also within the whole range of other functions that agriculture, as a business activity, realizes in rural areas. Production of organic agricultural food products in the world is constantly increasing, as the areas used for organic production are significant growing globally. The trade of organic agricultural food products, as expected, grows mainly in the countries with higher purchasing power, and higher environmental and food health consciousness and habits of the</p><p><br />VI<br />producers. At the same time, there is a significant increase in the demand for this kind of agricultural food products. The Republic of Serbia has significant potential for production of organic agricultural food products. This is due to its natural potentials, awareness of the need for quality in a number of industrial branches; large areas of agricultural land that have not been contaminated or intensely farmed, which can speed up and facilitate the conversion; the positive attitude towards organic farming among university staff, many farmers and consumers, as well as free trade agreements (EFTA, CEFTA, Russian Federation, Belarus, Turkey). However, the population in Serbia is still not sufficiently educated in the field of organic production, there is unfavorable structure of the farms (a large number of small farms, which do not cooperate; aging of the farmers; the traditional approach to production; crisis of the livestock sector), as well as inadequate application of environmental marketing, insufficiently aware and informed consumers, on the one hand, and insufficiently wide assortment, quantity of products and steady offer, on the other. The market of organic food products is characterized mainly by low purchasing power of the population, lack of consumer awareness and low environmental awareness of the population in Serbia. The analysis of the market in Serbia showed great potential to increase the production and exports to foreign markets, while the increasing consumption of these products in the domestic market is still limited by the purchasing power of domestic consumers. On the other hand, problems of the legislative regulation of the sector of organic farming, problems of the regulation of certification bodies, low volume of production, and the fact that still primary, instead of processed organic products are exported, prevents the increase in the value of total exports.</p>

The thesis has been focused on testing of micromethod of DNA isolation from leaves, fruits and fruit products. Jams were selected for the analysis of plant DNA in technologically processed foods. Plant leaves, fruits, and jams were homogenized using plastic copist in a lysis buffer containing 2% cetyltrimethylammonium bromide (CTAB) with 2.5M sodium chloride (NaCl). Microisolation of plant DNA was performed using poly(hydroxyethylmethacrylate-co-glycidylmethacrylate) – P(HEMA-co-GMA)microparticles. Isolated the DNA concentration and purity were assessed by UV light aborbance using a spectrophotometer. After that, amplification of the DNA was tested in PCR. Primers specific for plant ribosomal DNA: 18S_for a 5,8S_rev (PCR product - 700bp), 26S_for a 26S_rev (PCR product - 220 bp), 18S_for a 18¬S_rev (PCR product - 263 bp) were used. The PCR conditions were optimized and the effect of the amplicon length on its detection was followed. PCR products were detected by agarose gel electrophoresis. It was shown that DNA isolated from almost all of leaves using magnetic particles was in PCR-ready quality in contrary to the fruits. DNA amplified in PCR with primers giving short PCR products was isolated from almost all tested jams. The method must be optimalised, yet.
