Abstract: Flowers, cherished for their fleeting beauty, have found a new lease on life through the art of preservation. This study delves into the intricate world of drying methods, specifically focusing on roses (Rosa hybrida L.), aiming to enhance their longevity, colour retention, and overall acceptability. Conducted at Pt. K.L.S. College of Horticulture and Research Station in Rajnandgaon, Chhattisgarh, from March to May 2023, the study compared six rose drying methods: air, sun (sand-embedded), press, water, microwave (sand-embedded), and silica gel embedding. Using a randomized design, each method dried five roses (observations on three). Color, texture, shape, appearance, and brittleness were rated (1-5), while weight, moisture loss, and drying time were measured. Silica gel embedding excelled in visual quality and moisture control, making it the optimal method for preserving roses. Results reveal the prowess of embedded drying with silica gel (T₆), achieving peak scores in visual quality parameters. The method not only maintains superior colour retention but also excels in texture, shape, overall appearance, and brittleness. Quantitative data portrays the delicate dance of moisture loss, where microwave drying (T₅) stands out for its rapidity, albeit with the highest loss percentage. Time taken for drying is a symphony orchestrated by microwave drying, showcasing efficiency in both days and hours. In conclusion, this study advocates for the Embedded Drying (Silica Gel) method as the optimal choice for drying roses. Beyond aesthetics, it sheds light on the delicate balance between moisture loss and drying time, while emphasizing the economic efficiency of this method.
