Abstract: Methods for preparing soft gelatin capsules containing fragrances are disclosed. The desired fragrance is dissolved in a solvent system comprising a volatile solvent, a non-volatile cosolvent, or a combination of a volatile solvent and a non-volatile cosolvent or cosolvents. The resulting mixture is then encapsulated between gelatin ribbions prepared with an odor-free gelatin plasticized with a partially dehydrated, hydrogenated glucose syrup.

Abstract: A method is disclosed of preparing a beverage in the form of a dilute aqueous solution, suspension or dispersion of an encapsulated product. The capsule is added to a potable liquid, and the capsule material breaks down when submerged in the liquid to release its contents and itself dissolve. A primary advantage of providing the product in this way is that it can be confined within the capsule in liquid form, and can therefore disperse or dissolve in water more readily. Additionally, the capsule would normally sink to the bottom of the body of water before releasing its contents, thereby ensuring that the contents are released within the body of water, and not at the surface thereof.
