   Sammanfattning : Timber products subjected to climatic variations commonly display moisture-induced distortions that can lead to serious problems for end-users. The aim of the thesis, which consists of an extended summary and six appended papers, was to investigate the potential of using the gluing technique suggested here for dealing with problems of moisture-induced distortions and developing the heat and mass transfer models which such distortion analyses require.

4. 3. Diffusion of Water in Foods during Heating

   Författare :Karin Thorvaldsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; mass transfer; mass transport; porous; water; moisture; heat; food;

   Sammanfattning : The overall aim of this research was to improve the knowledge of diffusion of water in foods during heating, so that the final quality of foods after heat processing could be predicted and controlled. The work consisted of three main parts. The first part involved the development of a method to study the diffusion. LÄS MER
