  • Patent number: 5580593
    Abstract: A process for encapsulating an aroma or flavour for a beverage. An oil-in-water emulsion is formed from a vegetable oil, an aqueous medium, and a water-soluble, carbohydrate-based, film forming agent. A sufficient amount of the film forming agent is added so that the aqueous phase of the emulsion contains at least 50% by weight of the soluble carbohydrate solids. The oil-in-water emulsion is sprayed onto a soluble beverage powder whereupon the aqueous layer of each droplet rapidly desiccates to form the capsules; the moisture content of soluble beverage powder after spraying being less than 5% by weight. In use, the soluble beverage powder is dissolved in hot water to release the aroma or flavour.
    Type: Grant

  • Patent number: 5496574
    Abstract: A process for encapsulating an aroma or flavour for a beverage. An oil-in-water emulsion is formed from a hydrolyzed vegetable oil, an aqueous medium, and a water-soluble, carbohydrate-based, film forming agent. A sufficient amount of the film forming agent is added so that the aqueous phase of the emulsion contains at least 50% by weight of the film forming agent. The oil-in-water emulsion is sprayed onto a soluble beverage powder whereupon the aqueous layer of each droplet rapidly desiccates to form the capsules; the moisture content of soluble beverage powder after spraying being less than 5% by weight.

  • Patent number: 5287797
    Abstract: A brew basket is disclosed for use with conventional coffee makers of the type found in offices, hotels and restaurants. The brew basket is configured to receive ground coffee in the form of a compressed wafer and provides increased extraction of coffee solids from compressed coffee wafers and a significant reduction in extraction time. The basket has a relatively shallow profile and is dimensioned so that when the brew basket is mounted on the coffee maker, substantially the entire upper surface of the compressed wafer disposed in the brew basket is wetted by the hot water discharged from the spray head of the coffee maker. In addition the basket is dimensioned to maintain a water level in the brew basket sufficient to at least partially submerge the compressed wafer during extraction, to further increase extraction efficiency.

  • Patent number: 5047252
    Abstract: A beverage infusion device for preparing an individual cup of an infusible beverage such as coffee and tea. The device includes one or more porous pouches containing infusible material permanently or removably secured to a rotatable, hand held shaft, with the pouches extending radially outwardly from the shaft and dimensioned to fit within a conventional beverage cup or mug. In use, the device is inserted in a cup of hot water and the shaft is rotated between the thumb and finger of the user in alternating clockwise and counter-clockwise directions. Upon rotation of the shaft and the pouches secured to the shaft, a centrifugal flow pattern is created in water which enhances the efficiency of extraction of the infusible material. When the pouches are permanently secured to the shaft, the entire device is discarded after use. When the pouches are removably secured to the shaft, the pouches are separated from the shaft after use and discarded, with the shaft portion of the device being reusable.

  • Patent number: 4237288
    Abstract: A process is disclosed wherein the decaffeination of solutions of caffeine in fatty media is effected with hydrophilic, phenol/formaldehyde polymeric resins having phenolic functional groups. In particular, the solutions are contacted with resin to effect decaffeination and the solvent medium is recovered, whereas the exhausted resin containing adherent caffeine and any non-caffeine solids may be regenerated for re-use. Other features of the invention are described in the specification.
