Effects of container geometry and material on microwave cooking performance, as measured by evenness of cooking, firmness, and moisture content were compared. Three food items were heated in round, tube, loaf, and square containers made of clear glass, amber glass, thermoset polyester, and polysulfone. Unflavored gelatin, custard, and cakes were prepared three times in each of the 13 microwave containers. Evenness of cooking was determined by comparing meltdown and temperature in gelatin, temperature and separation/uncooked portions in custard, and index to volume in cakes. Firmness was measured in custard while moisture content was determined in cakes. In analysis of the data, ANOVA and Duncan's multiple range test were performed. Significant differences were found between shapes as food items heated more evenly in tube and round containers than in square containers. Food quality was affected more by shape than by material. Foods prepared in the, plastic materials were more evenly heated than in the glass materials. Statistically, shape and material interacted with each other for three measures of microwave appliance performance temperatures and separation/uncooked portions of custards, and index to volume in cakes. The interaction of shape and material was greater as the heating time increased. / Master of Science

<p>The interest for food and cooking has probably never engaged the people of Sweden as much as it does today. Especially cookbooks are selling better than ever which has been a quite constant trend since the mid 90's. This study explores the connection between visual communication in Swedish cookbooks and the post-modern values which have influenced the market climate and the visual culture. I have used a theoretical framework as reference consisting of theories of semiotics, visual rhetoric, marketing communications and postmodernism. I have been studying six cookbooks, three from the late 00's and three from the early 90's, from the two separate angles of their graphic design and photographic material. The survey has been conducted by using both qualitative and quantitative methods to make it possible to both gather information about the impression of the visual communication as well as statistics of space given to text and images as well as main motives in the photography. In my essay I discuss the meaning of the differences between the cooking books of the separate time periods along with the above mentioned angles with the theoretical framework in mind. I also discuss the question about what in fact makes a cooking book have costumer value. As a conclusion I state that cookbooks by updating their image of what a cookbook is supposed to be, succeeded to reach new markets with post-modern influenced preferences by making cooking part of an experience in the mind of the consumer.</p>

With obesity in adolescents becoming a major health problem in the United States, there has been an expansion in the use of nutritional education programs as intervention. Effective nutrition education can decrease the incidence of obesity and other diet-related chronic diseases, type-2 diabetes, cardiovascular disease, and hypertension. This dissertation in practice proposes to design a nutrition education program, integrating farm and culinary activities into a nutrition education curriculum. The program is designed as a stand-alone program, but for this practice, implementation integrates the nutrition education program into the Film @ 6 after-school program – a STEM-focused program designed to assist sixth graders in their first year of middle school – at Southeast Middle School in Salisbury, Rowan County, North Carolina (NC). This experiential nutrition education program will provide instruction and activities in order to increase nutritional knowledge, improve culinary techniques, and increase consumption of fruits, vegetables, and minimally processed foods of sixth grade students as a means to address the overweight and obesity risks of middle school children. Children and adolescents are considered the priority population for intervention strategies because 70% of obese adolescents become obese adults and it is difficult to reduce excessive weight once established (Dehghan, Akhtar-Danesh, & Merchant, 2005).

Cooking stove technologies are crucial for meeting household energy needs, yet many lack access to clean solutions, leading to Household Air Pollution (HAP) and associated health risks. There is an urgent need to understand and mitigate environmental and health challenges posed by traditional stoves burning solid fuels like fuelwood. This thesis examines the environmental and human health impacts of different cooking fuel options using a Life Cycle Assessment (LCA) approach. A case study is developed in the state of Tamil Nadu in India, considering different cooking fuel mix scenarios and sustainable transition in the sector. Key impact categories such as Global Warming Potential (GWP), Fine Particulate Matter Formation, and Human Health are examined. Findings reveal persistent challenges, particularly with solid fuels like firewood, contributing to HAP and adverse health effects. Transitioning to renewable energy sources such as Biogas and Electricity is crucial for mitigating environmental impacts and improving public health outcomes. Eliminating firewood in the Sustainable scenario fuel mix could result in a 43% reduction in GWP, an 87.5% reduction in delicate particulate matter, and a 75% improvement in human health. This study provides insights for policymakers to develop interventions promoting sustainable cooking practices and enhancing community well-being in Tamil Nadu and beyond. / Köksspis-teknologier är avgörande för att tillgodose hushållens matbehov, men miljontals saknar tillgång till rena matlagningslösningar, vilket leder till hushållsluftföroreningar (HAP) och associerade hälsorisker. Det finns ett brådskande behov av att förstå och mildra miljö- och hälsoutmaningar som traditionella spisar, som använder fasta bränslen såsom ved, innebär. Denna avhandling undersöker miljö- och hälsoeffekterna av olika alternativ för matlagningsbränsle med en livscykelanalys (LCA)-ansats. En fallstudie har utvecklats i delstaten Tamil Nadu i Indien, där olika scenarier för blandning av matlagningsbränslen och en hållbar övergång inom sektorn övervägs. Viktiga faktorer som global uppvärmningspotential (GWP), bildning av fint partikulärt material och människors hälsa undersöks noggrant. Resultaten avslöjar ihållande utmaningar, särskilt med fasta bränslen som ved, som bidrar till HAP och negativa hälsoeffekter. Övergången till förnybara energikällor som biogas och elektricitet är avgörande för att mildra miljöpåverkan och förbättra folkhälsan. Att eliminera ved i bränslemixen i det hållbara scenariet kan leda till en 43 % minskning av GWP, en 87,5 % minskning av fintpartikulärt material, och en 75 % förbättring i mänsklig hälsa. Genom att utnyttja insikterna från denna studie kan beslutsfattare och intressenter utveckla riktade insatser för att främja hållbara matlagningspraxis och förbättra välbefinnandet för samhällen i Tamil Nadu och vidare.

Dissertation submitted in fulfilment of the requirements of the Degree of Magister Technologiae: Food and Nutrition, Durban University of Technology, 2012. / There is lack of data on the dietary intake and patterns of Lindelani adolescents, which necessitates comprehensive nutritional assessment. Objectives: The objectives were to investigate the dietary intake and nutritional analysis of lunchbox contents of high school girls (13 -18 years of age) in Lindelani and evaluate its contribution to their dietary intake. Methodology: The study was of a descriptive nature with an analytical component, a convenience sample of 61 learners who brought lunchboxes from home and completed a socio- demographic questionnaire, QFFQ and two 24- hour recall questionnaire used for evaluation of their dietary intake. Anthropometric measurements, including body composition, were performed. Anthropometric data were captured on a Microsoft Excel spreadsheet and displayed on WHO growth charts to determine stunting, wasting, underweight and over-weight. . Lunchboxes were required and collected without informing participants to avoid bias, each lunch box was weighed and the content recorded and analysed using Food Finder 3 computer software program. It was analysed by selecting the mean intake of the group and comparing it to the Daily Recommended Intake (DRIs) for this group of individuals. Results: The results indicated that the food group most commonly consumed was carbohydrates. The lunchbox mean energy content was 90.14 kJ (>100% of DRIs) which is a big portion for a lunchbox since there are other meals of the day to be eaten too. The mean intake of fruit portion consumed was 135g which was only consumed by 1% in the top 20 food items compared to 141.82g consumed by 18% in 24- hour recall. Bread, margarine and polony were commonly consumed in QFFQ, Lunchboxes and 24- hour recall. Fat consumption for lunchboxes was 34.04% higher than the WHO nutrient intake goal which put these teenagers at risk of overweight. Fruit and vegetable intake was 106.95g (QFFQ), 107.27g (24-hour recall) and 109.49g (mean lunchbox content). This indicates poor intake of fruit and vegetables, being far lower than WHO recommendation of 400g per day. Dietary fibre was also found below 25g. Conclusion: Although the group seemed to consume all the nutrients but it is a small sample of the population. The study indicated that the majority of the respondents consume mostly IVcarbohydrate diets and the lunchboxes did not meet the basic requirements of a balanced diet. The lunchboxes contributed on average one third of the girl’s daily food intake.

Thesis (MPhil (Modern Foreign Languages))--University of Stellenbosch, 2008. / This study focuses on foreign language teaching and learning in the professional workplace. A gap was perceived in the catering industry where chefs and waitrons are required to use French cooking terminology in their profession without ready access to the correct usage of this terminology. The purpose of this study is to address this gap and to offer a solution to the observed need. The study concentrates on the reading and writing of menus in French. The reason for this focus is that this is the area where French cooking terminology is arguably needed, as it is here where the incorrect usage of the French language is most evident.

The influence of catalyst characteristics, i.e., acidity and porosity on the product distribution in the cracking of triglyceride-rich biomass under fluid catalytic cracking (FCC) conditions is reported. It has found that the degradation degree of triglyceride molecules is strongly dependent on the catalysts’ acidity. The higher density of acid sites enhances the conversion of triglycerides to lighter products such as gaseous products and gasoline-range hydrocarbons. The formation of gasolinerange aromatics and light olefins (propene and ethene) is favored in the medium pore channel of H-ZSM-5. On the other hand, heavier olefins such as gasoline-range and C4 olefins are formed preferentially in the large pore structure of zeolite Y based FCC catalyst (Midas-BSR). With both catalysts, triglyceride molecules are mainly converted to a mixture of hydrocarbons, which can be used as liquid fuels and platform chemicals. Hence, the utilization of the existing FCC units in conventional petroleum refineries for processing of triglyceride based feedstock, in particular waste cooking oil may open the way for production of renewable liquid fuels and chemicals in the near future. / Bài báo trình bày kết quả nghiên cứu khả năng tích hợp sản xuất nhiên liệu sinh học và hóa phẩm từ nguồn nguyên liệu tái tạo sinh khối giầu triglyceride bằng công nghệ cracking xúc tác tấng sôi (FCC) trong nhà máy lọc dầu. Kết quả nghiên cứu cho thấy xúc tác có ảnh hưởng mạnh đến hiệu quả chuyển hóa triglyceride thành hydrocarbon. Tính acid của xúc tác càng mạnh thì độ chuyển hóa càng cao và thu được nhiều sản phẩm nhẹ hơn như xăng và các olefin nhẹ. Xúc tác vi mao quản trung bình như H-ZSM-5 có độ chọn lọc cao với hợp chất vòng thơm thuộc phân đoạn xăng và olefin nhẹ như propylen và ethylen. Với kích thước vi mao quản lớn, xúc tác công nghiệp FCC dựa trên zeolite Y ưu tiên hình thành C4 olefins và các olefin trong phân đoạn xăng. Ở điều kiện phản ứng của quá trình FCC, triglyceride chuyển hóa hiệu quả thành hydrocarbon mà có thể sử dụng làm xăng sinh học cho động cơ và olefin nhẹ làm nguyên liệu cho tổng hợp hóa dầu.

The general aim of this thesis is to use foodwork and cooking in Sweden as a way to better understand theoretical questions about men and masculinities. Paper I discusses how an increased public interest in elaborate cooking and gastronomy in Sweden, a country with a cultural idealization of gender equality, could explain why men in Sweden assume responsibilities for domestic cooking without feeling emasculated. Papers II, III and IV draw on interviews with 31 men from 22 to 88 years of age and with different levels of interest in food. Paper II shows how domestic foodwork and cooking are associated with ideas of Swedish progress in terms of gender equality and culinary skills. Paper III demonstrates further that domestic cooking is not only a responsibility which men assume, but also a way of being sociable with friends, partners and children. Thus, both papers II and III challenge the idea that men only cook at home if they enjoy it. The data rather indicate that domestic foodwork responsibilities are a cultural expectation of men in Sweden, ingrained in desirable masculine practices. Paper IV explores men’s responses to media representations of food. The interviewed men responded to these representations with indifference, pragmatism, irony, and at times even hostility. In general, the responses are based on gender and age-differentiated taste distinctions and notions of masculine and culinary excess. Paper V uses a mix of texts (81 online texts and two magazines) and observations from the food fairs GastroNord (2014 and 2016), Mitt kök-mässan (2014) and the chef competition Bocuse d’Or Europe (2014) complemented with pictures and videos. I argue that a Swedish culinary community that promotes Swedish culinary excellence is constructed by drawing on preestablished national (self-)images. This culinary community is constructed as open and tolerant, with ethical concerns for the environment and for nonhuman animals. Its culinary icons are represented by chefs in whites and the leading restaurants. In sum, this dissertation provides empirical and theoretical contributions to both food studies and gender studies that critically scrutinize men and masculinities. Food-issues are permeated by gender, both in people’s everyday life and in the gastronomic elite.
