The study was conducted to explore the effect of selected preservation treatments on the quality of Statice flower in floral freeze dryer. Preservation of flowers in freeze drying process retains its pigment (colour) and structural parts (cells) and thus remains as fresh bloom for years. Prior to freeze drying process, flowers were treated with set of chemical compounds for retaining the inherent qualities in preserved flowers. The qualitative characteristics of flowers were evaluated by expert panel. Flowers treated with a chemical compound that had a blend of exchange medium colour preservatives, colour fixatives, buffers, modifiers, pH regulator, and shatter resistant compound (Ethyl vinyl acetate) resulted in flower that was closer to natural.
