The term “functional food” (FF) has a variety of definitions resulting in term ambiguity. It is unclear Registered Dietitians’ (RDs) understanding and practices about FF. A descriptive, cross-sectional study investigated RDs’ perceptions, attitudes and practices regarding FF. A national random sample (n=1800) of RDs was mailed a FF questionnaire, 385 (22%) responded. Given five definitions from food-nutrition authorities, the majority of RDs did not agree on a definition, although three-fourths (n=292, 75.8%) perceived fortified foods as FF. Registered Dietitians agreed FF could improve health (n=266, 69.1%), prevent disease (n=282, 73.2%) and treat clientele (n=246, 63.9%), however were neutral (41.6%) or disagreed (37.7%) FF were herbs, or equivalent to medicine (32.7%, 49.2% respectively). Most RDs (n=290, 75.9%) ate FF; fewer (n=231, 61.4%) professionally recommended them. Nearly all (n=353) indicated interest in learning about FF. Registered Dietitians revealed inconsistencies between their perceptions, attitudes and practices regarding FF. Professional education is needed to resolve discrepancies regarding FF.

The thesis analyzes consumer protection on the market of genetically modified products in the Czech Republic and the European Union. Development of the world legislation in the sphere of genetically modified products and its current situation in the EU and the Czech Republic are specified in the thesis. Consumer protection in the sphere of GMO is evaluated on the example of member states of the European Union -- the Czech Republic, France and Spain -- as well as in the states with a high level of share of genetically modified products in the food production -- the United States of America and Brazil. Practical part of the thesis is focused on the evaluation of knowledge level of inexpert public relating to the topic of genetically modified organisms and products. The conclusion of the thesis mentions the weak points of the current consumer protection on the market of genetically modified products in the Czech Republic and European Union together with suggestions for improving the present situation.

"Somos semillas" -we are seeds is a slogan, a sentiment, and a belief that emerges and circulates in a myriad of spaces from Ferguson Black Lives Matter protests advocating for racial justice in the United States, to struggles against state violence in Ayotzinapa, Mexico, to climate justice and food sovereignty movements in Latin America. Seeds are both symbolic and material embodiments of futurity. In this dissertation, I examine the discourses around seeds, particularly genetically modified seeds (GM), and the role of biotechnology as our only purveyor of futurity. In "Seeds", I examine the dominant discourses around GM seeds produced by pro-GM actors such as agro-industries including Monsanto and Syngenta, and USDAID programs such as Feed the Future. These discourses are constructed around social and environmental looming crises that include hunger and overpopulation, loss of biodiversity and climate change. In "Seeds", thinking through the decolonial option, I challenge the single Western narrative that presents GM seeds and crops as the only path to solve these crises and for humanity to have a utopian future."Seeds" takes on 'studying up' approach that as scholar Laura Nader argues investigates those in power instead of those that are being oppressed."Seeds" then works alongside other academic, indigenous, campesin@s, and farmer intellectuals and activists to elucidate a number of ways that people around the world are engaging with such crises and are building different paths to decolonial futures.

Assim, o objetivo deste trabalho foi estudar a percepção do consumidor brasileiro sobre o uso de engenharia genética na produção de alimentos sob uma perspectiva de pesquisa quali-quantitativa. Inicialmente foram realizadas entrevistas com 48 consumidores na cidade de Campinas,SP, e os resultados mostraram que, de forma geral, há desconhecimento sobre os fundamentos científicos da biotecnologia moderna, bem como da sua finalidade na produção de alimentos. Os respondentes mostraram-se mais favoráveis à aplicação de engenharia genética aos produtos de origem vegetal e àqueles produzidos com uso de micro-organismos, em detrimento dos produtos de origem animal, notadamente a carne. Benefícios, tais como aumento de produtividade, melhoria de qualidade e possível redução do preço dos alimentos mostraram-se como motivadores do consumo. Por outro lado, há desconfiança justificada pelo risco de efeitos adversos à saúde e também ao meio ambiente, sobretudo em longo prazo. Três segmentos de consumidores foram identificados, quais sejam, os de atitude positiva em relação ao uso da engenharia genética na produção de alimentos, os de atitude negativa e os de atitude neutra a positiva. No segundo momento da pesquisa, avaliou-se a intenção de compra de alimentos produzidos por biotecnologia moderna por 55 consumidores combinando-se três fatores: tipo de alimento (de origem animal, vegetal ou produzido por processo microbiológico), denominação ("organismo geneticamente modificado" ou "transgênico") e benefícios (à saúde, ao meio ambiente ou nenhum benefício). A Análise de Conglomerados associada à Análise Conjunta demonstrou que, 1) produtos de origem animal são preferidos em comparação aos de origem vegetal ou produzidos por ação de micro-organismos, 2) a denominação "organismo geneticamente modificado" é preferida à "transgênico" e, finalmente, 3) benefícios à saúde ou ao meio ambiente são menos importantes e úteis na intenção de compra. Como conclusão, este estudo aponta a necessidade de estratégia de comunicação à população sobre os fundamentos, os possíveis benefícios e os riscos da engenharia genética de forma a promover o debate social e escolha consciente dos consumidores brasileiros em relação aos alimentos produzidos com tecnologias associadas / Abstract: Although Brazil is one of the world's largest producers of transgenic food, there are few studies assessing local public opinion on the subject. The aim of this work was to study the perception of Brazilian consumers about the use of genetic engineering on food production using a quali-quantitative research perspective. Firstly, 48 consumers were interviewed in the city Campinas, SP, and the results showed that, in general, lack of knowledge about the scientific fundamentals of modern biotechnology and its purposes on food production. The respondents showed to be more favorable to the application of genetic engineering on plants and and food produced by microbiological process, than on animal origin products, especially meat. Benefits, such as increased productivity, improved quality and possible price reduction appeared as the main drivers of consumption. On the other hand, it seems to be distrust justified by the risk of adverse effects on health and also to the environment, particularly in the long term. Three consumer clusters were identified: one showing positive attitude; another one with negative attitude; and a third group of consumer showing neutral to positive attitude towards the use of genetic engineering in food production. In the second part of the study, a conjoint study with 55 consumers was performed in order to assess the purchase intention of concepts of foods produced by modern biotechnology. Concepts were defined by combining three factors: type of food (animal, plant or produced by microbiological process), name ("genetically modified organism" or "transgenic") and benefits (to the health, to the environment or no benefit stated). Cluster Analysis associated with Conjoint Analysis showed that: 1) animal products are preferred in comparison to plants or food produced by microbiological process, 2) the name "genetically modified organism" is preferred to the "transgenic" and finally, 3) benefits to health or to the environment are less important in the purchase intention. In conclusion, this study indicates the need of a communication strategy to inform the Brazilian population about the fundamentals and the possible benefits and risks of genetic engineering in order to promote a social debate and more conscious choice by local consumers regarding food produced with associated technologies / Mestrado / Consumo e Qualidade de Alimentos / Mestra em Alimentos e Nutrição

This study develops a real options model of agbiotechnology and is applied to three genetically modified (GM) traits. Each trait is evaluated as growth options where technical or marketing milestones must be completed before management can exercise the option to invest further in trait development. The real options values are evaluated by employing a binomial tree which is simulated using distributions for random elements within stages of the growth option. Mean option values were negative for the discovery stage for fusarium-resistant wheat and for all but the regulatory submission stage for Roundup Ready wheat. The length of the regulatory submission stage had the greatest negative impact on the value of the option while the ability of the firm to maximize technology-use-fees had the greatest positive impact. Additionally, traits adapted to crops with larger potential market size are more likely to be in the money than traits developed for smaller market segments.

This study develops a framework for pricing output traits derived from agriculture biotechnology and the effects on competing technologies post-introduction of the genetically modified (GM) variety. The price impact model determines processor or consumer adoption rates and changes in processor, farmer, and tech firm surplus as a result of the release of the new GM variety. Several implications result from this research. First, adoption of the GM variety may not be as high as expected due to the lower cost of using conventional varieties for processing or consumption inputs. Second, both processors who adopt the GM variety and those who continue to use conventional varieties will have an increase in surplus as a result of the introduction of the GM variety. Lower costs of conventional varieties will also result in new entrants into the market.

In this study, two diverse scientific areas of research, namely, biological-chemical and public administration, were drawn upon to find an answer for improved risk governance of genetically modified organisms (GMO/GM) and pesticides. The need for such a study appeared from the constraints experienced with regulatory approval of GMO crops in South Africa. The knowledge gained from research on risk governance of GMOs could also be applied to pesticides. Protracted procedures causing delays in approval and increasingly stringent regulatory requirements of GMOs resulted in negative implications for research, development and commercialisation. Approval of several South African co-developed GMOs has been delayed or rejected that resulted in withdrawal or reducing of research activities, apart from appeals against decisions. The objective of the study was to identify some of the reasons for delays as experienced in risk assessments and to propose remedial actions, including the critical interface between role players in risk governance. The approach taken in this research was to obtain, by means of a questionnaire, a broad view of risk governances of GMOs as measured with criteria of good governance experienced by scientists of biotechnology and related disciplines. This was followed by another questionnaire with focus on one specific area that caused delays for GMO permit applicants. The investigation included analysis of South African legislation, guidelines and interviews. The research on risk assessment narrowed down to the two areas, illustrated by South African applicable case studies, namely, food risk/safety assessment of GMO cassava and environmental risk assessment of GMO sorghum. Approaches to improve assessments are being recommended. Uncertainty in risk assessment is an important reality because of humankind‘s limited knowledge of nature. Uncertainty is further addressed by precautious management, described as the precautionary principle is a norm legislated by the South African government in line with international agreements (the Cartagena Protocol on Biosafety). The terminology, precautionary approach and principle are used interchangeably in literature. The application of the precautionary principle in South African legislation and the difficulty that could be experienced in decision making are illustrated in the case study on ‗possible unintended changes in endogenous allergens‘ in GMO maize. The research showed the importance of timely risk communication between risk assessors, risk managers (decision makers) and stakeholders in advance of the commencement of risk assessment. The importance of timely consideration of socio-economic impact of GMOs and pesticides is touched on. Risk governance structures, for both GMOs and pesticides are proposed, based on the most democratic and transparent governance models taking into consideration the European initiatives for improved risk governance. This included an interface for interaction among role players, namely, risk assessors, risk managers, scientists and stakeholders. The up-front role of an array of scientists, as the most trustworthy communicators in contentious scientific issues, is of specific importance because of the fast developing and very broad field of genetic modification of many crops. South Africa‘s national research institutes should play a much bigger role as scientific advisors in scientific risk policy making and framing for risk assessments. It is of great importance that risk assessments are focused on risks and not on the gathering of bucketsful of data; therefore, training in approaches to assessment of risk should be a priority. To achieve improvement on risk governance, the importance of policy development and the roles of all participants should be clear. Proposals for future research cover the many aspects that comprise trust in governance and the increased awareness of consumers and stakeholders of environmental risks and food safety. This study also paves a way for research on governance of phytopesticides and phytomedicines because of growing interest in these rich sources of new information that could be of great benefit to mankind. / Thesis (PhD)--University of Pretoria, 2013. / gm2014 / Paraclinical Sciences / Unrestricted

WRINKLED1 (AtWRI1) is a key transcription factor in the regulation of plant oil synthesis in seed and non-seed tissues. The structural features of WRI1 important for its function are not well understood. Comparison of WRI1 orthologs across many diverse plant species revealed a conserved 9 bp exon encoding the amino acids “VYL”. Site-directed mutagenesis of amino acids within the ‘VYL’ exon of AtWRI1 failed to restore the full oil content of wri1-1 seeds, providing direct evidence for an essential role of this small exon in AtWRI1 function. Arabidopsis WRI1 is predicted to have three alternative splice forms. To understand expression of these splice forms we performed RNASeq of Arabidopsis developing seeds and queried other EST and RNASeq databases from several tissues and plant species. In all cases, only one splice form was detected and VYL was observed in transcripts of all WRI1 orthologs investigated. We also characterized a phylogenetically distant WRI1 ortholog (EgWRI1) as an example of a non-seed isoform that is highly expressed in the mesocarp tissue of oil palm. The C-terminal region of EgWRI1 is over 90 amino acids shorter than AtWRI1 and has surprisingly low sequence conservation. Nevertheless, the EgWRI1 protein can restore multiple phenotypes of the Arabidopsis wri1-1 loss-of-function mutant, including reduced seed oil, the “wrinkled” seed coat, reduced seed germination, and impaired seedling establishment. Taken together, this study provides an example of combining phylogenetic analysis with mutagenesis, deep-sequencing technology and computational analysis to examine key elements of the structure and function of the WRI1 plant transcription factor.

Genetically modified food is a reality for many modern-day consumers around the world. With the introduction of GM food to the food market, consumers were faced with a number of new products and also familiar products containing new ingredients. The introduction of genetically modified food products to food markets around the world, led to a lot of controversy. In many cases consumer attitudes and perceptions of GM food products were revealed as fears, concern for, and avoidance of the new technology. Consumer attitudes, perceptions and acceptance towards the use of genetically modified foods or -food ingredients are currently highly relevant issues for role-player such as researchers, government, food companies, biotechnology companies, retailers and farmers all over the world.The importance of genetically modified food products in South Africa is increasing, even though the debate surrounding genetically modified food products lags behind many other (often more developed) parts of the world. Genetically modified white maize is among the agricultural crops approved for commercial production in South Africa. The production of genetically modified white maize in South Africa increased dramatically from its introduction in the 2001/2002-production season. White maize, especially in the form of super- and special maize meal, is an extremely important staple food source for consumers of all age groups in South Africa. The implication of the significant increase in the cultivation of genetically modified white maize is that the product is entering the South African food market at an increasing rate. In reality South African consumers are increasingly exposed to food products containing genetically modified white maize. This goes hand in hand with increasing consumer awareness regarding genetically modified food issues.The general objective of the dissertation is to develop an understanding of the perceptions, attitudes, acceptance and knowledge of South African urban consumers, regarding GM white maize as a staple food product within South Africa. The specific objectives are to identify trade-offs between selected attributes of maize meal and to determine the relative importance of selected GM characteristics within the trade-offs by means of a conjoint experiment, to construct market segments based on the outcomes of a conjoint experiment, to determine the effect of consumer perceptions on the sensory experience of white maize porridge and to determine the knowledge, perceptions and GM food acceptance of the different market segments.Quota sampling was applied to obtain a random sample of 80 urban white-maize consumers, based on the LSM (Living Standard Measures) market segmentation tool. The respondents participated in sensory evaluation of maize porridge. This was followed by a conjoint experiment designed around three selected product characteristic variables describing a 2.5kg packet of super white maize meal: “Brand variable”, “Genetic modification variable” and “Price variable”. Market segmentation was done through Ward’s hierarchical cluster analysis based on the conjoint results. The final phase of the experimental analysis involved the profiling of the identified clusters based on demographic variables, respondents’ knowledge of genetic modification and respondents perceptions, attitudes and acceptance towards genetically modified food.The limited sample size (80 respondents) could influence the ability of the results to reflect on the population of urban white maize consumers given the presence of GM food in the market. However, the experimental results should be seen in view of general trends in South Africa and available anecdotal evidence supporting the results of the study. The results of this study could go a long way in representing the results of a more representative sample of urban white maize consumers given the presence of GM food in the market.The cluster analysis revealed that the sample of urban, white maize consumers could be grouped into three meaningful and distinct market segments, based on their preferences for branded- versus non-branded white-grained maize meal, as well as their preferences for non-GM white maize meal versus GM white maize meal with various types of genetic manipulations. The “Anti-GM” segment (35% of the sample) is particularly negative towards GM food irrelevant of the type of genetic modification applied to the food. The “Pro-GM farmer sympathetic” segment (20% of the sample) is positive towards genetically modified food in cases where the farmer receives the benefit of the genetic modification. The “Pro-GM” segment (45% of the sample) is generally positive towards GM food, but especially when the consumer receives the benefit of the genetic modification. The results indicated that the differences among the cluster groups were more prominent than the differences among the LSM groups. Thus, the clusters were most effective to distinguish between sub-groups in the experimental sample.The results of the respondents’ knowledge of genetic modification indicated that there is some degree of confusion among respondents regarding the meaning of genetic modification, as well as discrepancies between perceived and actual knowledge levels of genetic modification. In general, the respondents’ knowledge of GM food is relatively low.A strong positive correlation was observed between the sample respondents’ exposure to GM food related terms and their perceived understanding of these issues, implying that the exposure caused the respondents to learn more about GM food related terms. The balanced GM food information presented to the respondents during the experimental procedure probably influenced their knowledge levels and opinions about GM food as the experiment evolved. Despite these observations the research methodology was still deemed as appropriate. The GM food knowledge gained by the respondents during the experiment could be seen as a simulation of situations where they could receive GM food information from external sources such as television, radio, magazines or newspapers. The cluster profiling revealed that urban white-grain maize consumers’ perceptions and attitudes towards GM food were the strongest distinguishing factors between the various market segments, especially the preferences of the various cluster groups for non-GM maize or maize that was genetically modified for consumer benefit or maize that was genetically modified for producer benefit. Demographic factors and GM knowledge aspects did not really contribute towards distinguishing between the clusters.The dissertation determined that there is a need for a better understanding of consumer perceptions, attitudes towards and acceptance of GM food products, which could enable producers and scientists to engage in more consumer driven product development and marketing activities. Consumer acceptance is the most critical factor for the success of GM food products within the South African food market place and could shape the future of the agricultural modern biotechnology industry and the agricultural sector in South Africa. / Dissertation (MSc (Agric) Agricultural Economics)--University of Pretoria, 2004. / Agricultural Economics, Extension and Rural Development / unrestricted
