In this work the effect of osmotic dehydration and type of osmotic solution on the colour and mechanical properties of osmotically dehydrated freeze-dried strawberries was shown. Strawberries were osmotically dehydrated in glucose and sucrose solutions with water activity of 0.9. Fruit were freeze-dried at heating shelves temperature of 50°C. It was shown that osmotic pre-treatment in sucrose and glucose solution does not cause any significant changes of colour coefficients and index for a majority of surfaces and for fragmented freeze-dried strawberries. The use of osmotic dehydration caused changes in the shape of compression curves for strawberries freeze-dried at tem-perature of 50°C. Many deflections were observed in the compression curves. Osmotic dehydration caused a decrease in the compression force necessary for deformation of dried fruit and work done to obtain this deformation in comparison to strawberries dried without osmotic pre-treatment.
