  • Process for dehydration of berries
    Patent number: 6312745
    Abstract: A process for drying antioxidant-rich berries (such as blueberries) to preserve their antioxidant action and their antioxidant compounds is disclosed. The process may conventionally dry the antioxidant-rich berries to remove 0 to 90% of the initial mass of water associated with them, but the important step is subjecting the antioxidant-rich berries to vacuum microwave drying (VMD) at an absolute pressure of 0 to 200 millimeters of mercury (mm Hg) (preferably 30 to 60 mm Hg) and 0.1 to 2 watts of microwave power/gram of berries (preferably 0.

  • Process for drying medicinal plants
    Patent number: 6128831
    Abstract: Medicinal plants are dried by applying microwave power to plant materials in a chamber under reduced pressure to reduce the moisture content of the plant materials without significantly reducing (oxidizing) the concentration of active medicinal component in the dried plant materials and thereby produce a dried medicinal plant product which more closely approaches the medicinal properties of the fresh plant than those of dried products produced by conventional air drying processes.
