1. 11. Group (IV) Metal-Catalyzed Direct Amidation : Synthesis and Mechanistic Considerations

   Författare :Helena Lundberg; Adolfsson Hans; Tom Sheppard; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalysis; amide; carboxylic acid; amino acid; titanium; zirconium; hafnium; organisk kemi; Organic Chemistry;

   Sammanfattning : The amide unit constitutes the backbone of proteins, and it is present in a large number of pharmaceutically active molecules, polymeric materials such as nylon and Kevlar, as well as in food additives like aspartame. Amides are produced in enormous amounts every year, thus, environmentally friendly and selective methods for their formation are of great importance. LÄS MER

3. 12. Mass transport mechanisms and module design aspects in the recovery of dilute volatile organic compounds by hydrophobic pervaporation

   Författare :Olivera Trifunovic; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Teknik; Technological sciences; Aroma recovery; Module design; Hydrophobic pervaporation; Mass transport;

   Sammanfattning : Hydrophobic pervaporation has gained a lot of attention as an alternative process for mild aroma recovery, but the real commercial applications of this process are still in their infancies. Better understanding of mass transport phenomena in composite pervaporation membranes is essential from the point of view of membrane manufacturing, while process simulation is an important tool for predicting pervaporation module performance.

4. 13. Analysing the carbon footprint of food : insights for consumer communication

   Författare :Elin Röös; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : In Europe, food consumption is responsible for approximately 30% of total greenhouse gas (GHG) emissions. There has been huge interest in estimating the carbon footprint (CF) of food products, i.e. the total amount of GHG emitted during the life cycle of the product, and communicating these to consumers to enable them to make informed choices.

5. 14. Consumer Perception of Organic and Genetically Modified Foods : Health and Environmental Considerations

   Författare :Maria Magnusson; Per-Olow Sjödén; Ulla-Kaisa Koivisto Hursti; Liisa Lähteenmäki; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caring sciences; consumer perceptions; organic foods; genetically modified foods; food choice; health; environmental concern; Vårdvetenskap; Caring sciences; Vårdvetenskap;

   Sammanfattning : The aim was to study consumer attitudes to and perceptions of organic and genetically modified (GM) foods and factors influencing the purchase/non purchase of these two types of foods. Data were collected by two questionnaire surveys (random nation-wide samples of 2000 consumers, response rate 58% and 39% respectively) and one interview study (n=40). LÄS MER

7. 15. Determination of folate for food composition data : development and improvement of analytical methods

   Författare :Hanna Sara Strandler; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Folate is B vitamin that is required for maintaining normal blood status. Recommendations on daily intake are based on information on blood folate status in relation to folate intake and bioavailability. Folate intake from a diet is evaluated by folate content in the food consumed. LÄS MER
