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 0.5 to 1 watt/gram) to reduce the moisture content to a residual moisture content of less than 35% of the dry weight of the final dry product.
Claims (17)
1 A process for drying antioxidant-rich berries containing an initial mass of water to preserve their antioxidant action and their antioxidant compounds comprising preliminary drying the antioxidant-rich berries to remove 0 to 90 % of the initial mass of water associated with the antioxidant-rich berries, subjecting antioxidant-rich berries to vacuum microwave drying (VMD) at an absolute pressure of 0 to 200 millimeters of mercury (mm Hg) and 0.1 to 2 watts of microwave power/gram of said antioxidant-rich berries containing said initial mass of water to produce dried antioxidant-rich berries wherein the moisture content of said antioxidant-rich berries containing an initial mass of water is reduced to a residual moisture content of less than 35% of the dry weight of said dried antioxidant-rich berries.
2 A process for drying antioxidant-rich berries as defined in claim 1 wherein said residual moisture content is between 10% and 25% of the dry weight of said dried antioxidant-rich berries
3 A process for drying antioxidant-rich berries as defined in claim 1 wherein said absolute pressure is between 30 and 60 mm Hg.
4 A process for drying antioxidant-rich berries as defined in claim 2 wherein said absolute pressure is between 30 and 60 mm Hg.
A process for drying antioxidant-rich berries as defined in claim 1 wherein said microwave power is applied at 0.5 to 1 watt/gram of antioxidant-rich berries.
6 A process for drying antioxidant-rich berries as defined in claim 2 wherein said microwave power is applied at 0.5 to 1 watt/gram of antioxidant-rich berries.
7 A process for drying antioxidant-rich berries as defined in claim 3 wherein said microwave power is applied at 0.5 to 1 watt/gram of antioxidant-rich berries.
8 A process for drying antioxidant-rich berries as defined in claim 4 wherein said microwave power is applied at 0.5 to 1 watt/gram of antioxidant-rich berries.
9 A process for drying antioxidant-rich berries as defined in claim 1 wherein said preliminary drying removes less than 70% of said initial mass of water.
Aprocess for drying antioxidant-rich berries as defined in claim 1 wherein said VMD
includes a cooling step following application of microwave power wherein said dried antioxidant-rich berries are subject to a vacuum without application of microwave power.
includes a cooling step following application of microwave power wherein said dried antioxidant-rich berries are subject to a vacuum without application of microwave power.
11 A process for drying antioxidant-rich berries as defined in claim 4 wherein said VMD
includes a cooling step following application of microwave power wherein said dried antioxidant-rich berries are subject to a vacuum without application of microwave power.
includes a cooling step following application of microwave power wherein said dried antioxidant-rich berries are subject to a vacuum without application of microwave power.
12 A process for drying antioxidant-rich berries as defined in claim 8 wherein said VMD
includes a cooling step following application of microwave power wherein said dried antioxidant-rich berries are subject to a vacuum without application of microwave power.
includes a cooling step following application of microwave power wherein said dried antioxidant-rich berries are subject to a vacuum without application of microwave power.
13 A process for drying antioxidant-rich berries as defined in claim 9 wherein said VMD
includes a cooling step following application of microwave power wherein said dried antioxidant-rich berries are subject to a vacuum without application of microwave power.
includes a cooling step following application of microwave power wherein said dried antioxidant-rich berries are subject to a vacuum without application of microwave power.
14 A process for drying antioxidant-rich berries as defined in any one of claims 1, 2 or 3 wherein said antioxidant-rich berries are blueberries.
15 A process for drying antioxidant-rich berries as defined in any one of claims 4, 5 or 6 wherein said antioxidant-rich berries are blueberries.
16 A process for drying antioxidant-rich berries as defined in any one of claims 7, 8 or 9 wherein said antioxidant-rich berries are blueberries.
17 A process for drying antioxidant-rich berries as defined in any one of claims 10, 11 or 12 wherein said antioxidant-rich berries are blueberries.
