11. The mechanisms controlling heat and mass transfer on frying of beefburgers
Sammanfattning : The aim of the present work was to gain better understanding of the mechanisms controlling heat and mass transfer during thermal processing of beefburgers. The effects of different factors such as the chemical composition and comminution of the meat raw material, the pan temperature and the meat patty diameter on the characteristics of heat and mass transfer were studied.

12. Species extinctions in food webs : local and regional processes
Sammanfattning : Loss of biodiversity is one of the most severe threats to the ecosystems of the world. The major causes behind the high population and species extinction rates are anthropogenic activities such as overharvesting of natural populations, pollution, climate change and destruction and fragmentation of natural habitats.

13. Optimisation and modelling of aroma recovery by pervaporation
Sammanfattning : During production of concentrated fruit juices, both physical and chemical losses of aroma compounds occur due to heat treatment such as pasteurisation and evaporation. This leads to an inferior quality of the final product. LÄS MER
14. Towards a Sustainable Food System : Entrepreneurship, Resilience and Agriculture in the Baltic Sea Region
Sammanfattning : This thesis compares conventional agriculture and Ecological Recycling Agriculture (ERA) in terms of their environmental and socio-economic effects. Environmental effects include greenhouse gas emissions and energy use, but this analysis focuses on nutrient losses. LÄS MER
15. Post-Harvest Losses, Intimate Partner Violence and Food Security in Tanzania
Sammanfattning : High levels of food losses occurring after harvesting offset the effort to increase food production. This situation increases the risk of food insecurity and low incomes among smallholder farmers. LÄS MER
