The study was undertaken to explore the effect of lyophilization technology on dried carnation flower. Lyophilization helped to retain the natural colour, form and texture of the dried flowers. Certain preservatives were selected, tested and evaluated to keep hold of innate characteristics of flowers. The flower treated with silver thiosulphate (STS) was found to be effective hydration treatments resulting flowers remained fresh up to 9d. Floral preservative (T8) was the best composition which retains inherent qualities of the flowers. The water content of the plant was replaced with a water immiscible organic solvent for pre treatments. Application of glazing medium as sealant was found best to protect flower from external environment conditions.
