“Aqua-space®”, a New Headspace Method for Isolation of Natural Floral Aromas Using Humidified Air as a Carrier Gas

A new method called “Aqua-space^®” was developed for the isolation of the natural fragrances of plants. Living flowers were enclosed in a space under simulated natural conditions, and humidified air was pumped into the space as a fragrance carrier. In a comparison among three isolation methods, i.e., Aqua-space^®, headspace, and solvent extraction, the Aqua-space^® method proved to be the most effective in retaining natural fragrances with abundant oxygenated components key to floral fragrances.
