Comparative evaluation of drying techniques and desiccants for enhancing drying quality of rose cv. gladiator

Abstract

The floriculture industry is experiencing rapid global expansion, driven by the immense potential for both domestic consumption and export of flowers. Among the cut flowers traded internationally roses hold a prominent position in terms of production and consumption. To capitalize on this demand and enhance farmers' income value addition has become crucial. In line with this objective a factorial experiment was conducted in 2020 using a completely randomized design. The experiment aimed to investigate the effects of different drying methods and desiccants on the sensory/quality parameters of roses during the drying and storage phases. The results revealed significant variations in the quality of dried roses based on the chosen drying methods and desiccants. Shade drying emerged as the superior method exhibiting favourable quality parameters such as bright colour, well-maintained shape, smooth petal texture and reduced mechanical damage during the drying process. During storage, shade-dried roses with sea sand demonstrated attributes of vibrant colour, smooth petals and minimal mechanical damage. However, sun-dried roses with silica gel exhibited well-preserved shape and showed fewer instances of pest and disease issues. Taking into consideration all aspects and the results obtained shade drying with sea sand proved to be the most effective approach for achieving desirable quality parameters during both the drying and storage stages.
