2. 1. Protein isolation from herring (Clupea harengus) using the pH-shift process - Protein yield, protein isolate quality and removal of food contaminants

   Author : Sofia Marmon; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; precipitation; acid; gelation; in vitro digestion; solubilization; herring; protein; salt solubility; pH; lipids; alkaline; transmission electron microscopy; dioxins;

   Abstract : Herring (Clupea harengus) contain valuable proteins but is difficult to process into high-quality foods due to its small size and high content of bones, heme-proteins and lipids. Herring is among the most abundant fish species in the world, but is currently utilized largely for fish meal and oil production. READ MORE

4. 2. Fish for Food and Ecosystem Function : Fisheries, Trade and Key Ecosystem Processes in Coral Reefs

   Author : Matilda Thyresson; Magnus Nyström; Edward H. Allison; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fish; food; key ecosystem processes; functional groups; coral reefs; trade; gear; small-scale fisheries; social-ecological systems; Zanzibar; Tanzania; Western Indian Ocean; naturresurshushållning; Natural Resources Management;

   Abstract : Fish is a key source of food and income to millions of people living along tropical coastlines. They also play essential roles underpinning key ecosystem processes in coral reefs. For example, herbivorous fish keep algae in check that otherwise may outcompete corals, reducing the reef’s social-ecological values. READ MORE

5. 3. Behaviour and metabolic rates of brown trout and Atlantic salmon : Influence of food, environment and social interactions

   Author : Linnea Lans; Larry Greenberg; Eva Bergman; Felicity Huntingford; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Salmo trutta; Salmo salar; behaviour; metabolic rates; Biology; Biologi;

   Abstract : For Atlantic salmon (Salmo salar) and brown trout (Salmo trutta), the decision to migrate or when to migrate is believed to be influenced by the individual’s metabolic rate (MR) relative its food intake. As MR was expected to be related to behaviour, the potential links between behaviour and metabolic costs was studied. READ MORE

6. 4. Migration from plastic food packaging during microwave heating

   Author : Jonas Alin; Minna Hakkarainen; Sahar Al-Malaika; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; migration; food packaging; microwave; degradation; food simulant; antioxidant;

   Abstract : Microwave heating of food has increased rapidly as a food processing technique. This increases the concern that chemicals could migrate from food packaging to food. The specific effect of microwave heating in contrast to conventional heating on overall and specific migration from common plastic food storage boxes was studied in this work. READ MORE

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

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

   Abstract : 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. READ MORE
