  2. 1. Environmental Imprint of Human Food Consumption : Linköping, Sweden 1870 - 2000

    Author : Tina-Simone Schmid Neset; Ulrik Lohm; Susanne Kytzia; Linköpings universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; food consumption; 19th and 20th century; Sweden; material flow analysis; MFA ; substance flow analysis; nitrogen; phosphorus; spatial imprint; lantbruk; miljöaspekter; livsmedelsindustri; livsmedelskonsumtion; markanvändning; Östergötland; 1800-talet; Food science; Livsmedelsvetenskap;

    Abstract : Human food consumption has changed from the late 19th century to the turn of the millennium, and so has the need for resources to sustain this consumption. For the city of Linköping, situated in southeastern Sweden, the environmental imprint of an average inhabitant’s food consumption is studied from the year 1870 to the year 2000. READ MORE

  4. 2. Contested Food : The Construction of Home and Consumer Studies as a Cultural Space

    Author : Karin Höijer; Christina Fjellström; Karin Hjälmeskog; Pia Christensen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Home and Consumer Studies; food; social constructionism; school; teachers; pupils; classroom; Kostvetenskap; Food; Nutrition and Dietetics;

    Abstract : Education about and for the home has been part of the Swedish education system for over one hundred years, and Home and Consumer Studies (HCS) has been compulsory for all pupils since the common nine-year school system was introduced in 1962. For all this time food has been a central theme, however we know very little of what food means in this context. READ MORE

    Abstract : A new type of Bioelectronic Nanosensor Device with potential applications in medicine,biotechnology and environmental analysis was designed. The nanosensor is based on RISFET (Regional Ion Sensitive Field Effect Transistor) technology. READ MORE

  6. 4. Characterisation of Food Associated Bacteria by DNA based Methods, with Special Reference to Enterobacteriaceae

    Author : Crister Olsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; 16S rRNA; TTGE; ribotyping; Rahnella; Klebsiella; HPI; Enterobacteriaceae; food; Livsmedelsteknik;

    Abstract : The presence of genes in food, encoding some virulence factors, was studied by PCR, and species of Enterobacteriaceae, associated with food, were studied by the DNA-based methods of TTGE, ribotyping and sequencing. The flora of fresh and chill-stored pork were analysed by a culture-independent approach, using specific amplification of 16S rRNA genes followed by cloning and sequencing. READ MORE

  7. 5. Sensory Quality and Consumer Perception of Wheat Bread : Towards Sustainable Production and Consumption. Effects of Farming System, Year, Technology, Information and Values

    Author : Iwona Kihlberg; Einar Risvik; Lisbeth Johansson; Stefan Sahlstrøm; Uppsala universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Domestic sciences; Product quality; Production quality; Sustainability; Organic farming; Wheat; Organic Food; Bread; Milling; Breadmaking; Sensory analysis; Consumers; Information; Values; Food acceptance; Hushållsvetenskap; Domestic science and nutrition; Hushålls- och kostvetenskap;

    Abstract : In order to study the effect of production systems aimed at sustainability on product quality and of sensory and non-sensory factors on product acceptance – the effect of farming system, year, milling and baking techniques on the sensory qualities of wheat bread as a model product was investigated using a descriptive test, and the effect of information and values on liking of bread using consumer tests.Whole wheat and white breads were baked with wheat grown in six lots in established conventional and organic farming systems in field trails, in two subsequent years for the white bread.
