Influence of Drying Methods and Parameters on the Quality of Jasminum sambac (L.) Flower Extracts Obtained via Supercritical Fluid Extraction

The extraction of plant essences and volatile organic compounds has been performed using various methods throughout history. The production of essential oils is a significant industry. One notable ornamental flower in the Philippines is Jasminum sambac (L.), also known as Arabian Jasmine or Sampaguita, which is highly fragrant and used in various cosmetics, food, and medicine. Researchers developed a method to produce quality J. sambac (L.) concrete using the Supercritical Fluid Extraction (SFE). Among the parameters explored, it was noted that no drying method had more pleasant odors, while other drying methods had varying effects on the extract scent. A temperature of 35 °C produces fragrant and sweet concrete, and temperatures above 40 °C result in burnt-smelling extract. Higher pressure enhanced the aroma and yield. The drying method also affected the output. Plucking petals before drying resulted in low-quality outcomes. Using a blow dryer damages the petals. A combination of low temperature, moderate pressure, and no drying method produced the best aromas. However, the process requires winterization to remove waxes in the samples, which will decrease the yield.
