The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..

Title: Food companies' work with CSR and its impact on consumer purchases of organic productsLevel: Final assignment for Bachelor Degree in Business AdministrationAuthor: Maria Nilsson and Mikaela JaredalSupervisor: Agneta SundströmDate: June 2015Aim: The study aims to understand and describe how food chains affect consumer choice to buy organic food and how it affects their buying behaviour.Method: Firstly a qualitative study was conducted. It consisted of six semi-structured interviews with store managers and employees on Willys and Coop in Sala and in Nyköping. Secondly a quantitative study was performed in the form of a questionnaire with 80 consumers in Willys and Coop stores located in Sala and Nyköping.Result & Conclusions: We have seen that price is important when consumers decide whether to buy organic food or not. This has been noticed by the food chains who work actively with being able to offer organic food at lower prices. Other factors that affect the consumers choice to buy organic products are offers, displaying and advertising.

Food is widely consumed and in 2011 an average American devoured approximately one ton of food. The production of these goods requires large amounts of energy and contributes to 22-31 % of all greenhouse gas emissions occurring in Europe. More than one third of the produced food is discarded instead of consumed, and food waste make up about 30 % of the waste generated by households. 60 % of this food waste could be avoided if the eatables were handled in a better way.Avoidable food waste arises partly because residues from food are not taken care of, and because the food is not stored in a way that optimise its durability. Residues arises part- ly because of the contradictory and complex demands of everyday life and are, because of our busy lifestyle, difficult to avoid.

This paper gives the reader an opportunity to explore new grounds regarding a relatively new field that has opened in Sweden. The result is based on an explorative research conducted by us, with starting point whether immigrants, consisting of Middle Eastern ones, can be seen as an attractive target group for big grocery shops. In order to understand whether they are attractive to target, we need to grasp underlying factors such as our research question: ?What are the habits of Middle Eastern consumers regarding food that marketers from Sweden can target?? To do so we were forced to investigate what kind of lifestyle an immigrant from the Middle East has, since the immigrant?s lifestyle influences what sort of food he/she will consume. When investigating the lifestyle we were able to concentrate on certain areas that we saw had a clear relation in influencing immigrants? food choices, such as religion, acculturation and so forth.

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

Clostridium difficile is a grampositive, anaerobe bacteria with a spore-forming ability. The bacteria is present in the environment, can be isolated from animals and is common in hospitals, where it is a known cause of severe diarrhoea in compromised patients. Lately scientists have been discussing whether Cl. difficile could be a new food-borne pathogen. The bacteria has been isolated from food-producing animals and from meat products. In this pilot study 82 meat products, bought from swedish shops during a periode of four months, were investigated.

AbstractFor several years, the organic food sales have increased, and more are choosing to buyorganic food of more diverse causes. Unfortunately the sales have slowed down the past year,a lot depends on the Swedish economy has been in decline and it has led to more will checkone more time on the price. But even if the sale value has decreased, the amount of organicfood has increased, it is because many stores have their own organic brands and they can pushprices down.The internet has become a great help in our daily lives, we do most our business via theInternet. But now we are not just paying our bills through the Internet anymore, we shopclothes, movies, music and books too. E-commerce was become more serious last decade andhas grown every year that has passed.

In this essay I have investigated how two families, with children, who have food allergies, experience what support and what treatment they get in preschool for their difficulties. I have interviewed two children and two parents. The study shows that the interviewed parents believe that more knowledge in the community and among staff in preschool, about food allergies, is needed. Parents wish that the staff should write an action plan that describes how to deal with children who have food allergies and that preschool invites parents and children to record results. It is important to consider an inclusive attitude so that children don?t feels excluded.There is some research going on around this subject and researchers agree that the incidence of food allergies in the society is growing, but that it is difficult to be able to present a certain theory why, and what the underlying factors are.

Every year, thousands tons of edible food are discarded by the grocery stores. This is food that could have gone to people that?s in need of it. In many countries, so called food banks are established in order to supply welfare organizations with this kind of food. Today there is no equivalent system existing in Sweden.

This thesis was performed as assignment from Fazer Food Services. The aim was to survey which Food additives that were present in the products in the quotation list of one of their suppliers to the Education and Nursing segment. The aim also was to perform a theoretical analysis of these Food additives and to make recommendations which Food additives are acceptable and which should be excluded from the products in the future. The recommendations are not published in this report, for more information Fazer Food Services can be contacted. Food additives which have already been approved are regarded as safe according to the safety evaluation methods available at the time of approval.

Reliable methods to analyze food for the presence of almond are important ? not only for those allergic to almond, but also for monitoring the compliance with labelling regulations (EG directive 2003/89). Until now the Swedish National Food Administration has used methods like rocket immunoelectrophoresis and real-time PCR to detect almond in food. These methods are, however, not sensitive enough for protecting the most sensitive individuals. Therefore, the performance of a commercial ELISA kit was tested with regard to specificity/cross reactivity and limit of detection for almond both in solution and in different matrixes.The limit of quantitation was at least 3,1 ppm (mg/kg) in solution and similar concentrations were measured in bisquits and chocolate.

Obesity and overweight are today classified as one of the largest epidemics in the Western world and is threaten a large part of the population. As a reaction to this a major health trend has emerged in recent decades. Every day consumers are exposed to information from the media about what is healthy or unhealthy to eat and the recommendations change frequently.There is great interest in healthy food on the Swedish food market, but still healthy foods only represents a small proportion of the total food sales. The essay examines the gap between the current and potential demand for healthy food and if it can be explained by any of the following factors: lack of information, price, taste or cognitive behavioral.To study these questions a quantitative method have been used and 213 questionnaires were collected. The intention is to draw general conclusions about the entire population.

This paper aims to investigate how human beings uses food to found an identity, with regards to how social class affects their choice of food and if trends play a part when it comes to cooking and purchasing food. The paper applies theorist Pierre Bourdieu's concepts such as habitus, capital and field.The main part of the material is composed of four interviews with seven informants; all of which is middle class. The paper also looks at how lifestyle, taste and attitudes to consumption are used when the informants build identity. The empirical part is split into three main subjects, where I first seek to find each informants food habits. What do they eat, and what do they not eat?It showed that a large part was due to their varied lifestyles, however generally speaking the day to day meals should be quick while meals during the weekends could take longer and also cost more.
