Abstract: A porous, crunchy dried banana food product is made by mixing a ripe banana puree and either ripe or unripe banana flour to form a composition, and exposing the composition to microwave radiation at a pressure less than atmospheric to puff and dry the composition, producing the porous, crunchy dried banana food product. The method enables a food product based on banana puree to be dried to a porous, crunchy snack product by means of microwave vacuum drying without requiring non-banana thickeners.

Abstract: Methods for drying cannabis in continuous throughput-type and batch-type microwave vacuum drying apparatus. One method uses a vacuum chamber having a plurality of adjacent drying zones. The cannabis is conveyed through each of the zones while exposing it to microwave radiation. Each of the drying zones has a microwave power level different from that of an adjacent drying zone, the microwave power levels of zones varying from each other in a non-linear arrangement from the first zone to the last zone. In a batch method, cannabis is loaded into a vacuum chamber, the pressure is reduced, and the cannabis is irradiated with microwave radiation at a first power level. The surface temperature of the cannabis is measured and when the temperature exceeds a specified temperature for a time period greater than a first time period, the power level is reduced to a lower power level for a second time period. The methods of drying maximize the retention of terpenes in the cannabis.

Abstract: A process for making a shelf-stable food, not requiring preservatives or refrigeration and in a form that is convenient for use as a snack food. A block of tofu or wheat gluten is first frozen so as to cause the formation of ice crystals that form cavities within the block. The frozen block is then thawed, cut into smaller pieces and drained of excess water. The thawed pieces are dried in a microwave-vacuum dehydrator to produce a crunchy food product.

Abstract: A method of drying high sugar content food products such as honey and molasses in a vacuum microwave chamber. The method comprises loading the food product into the vacuum chamber, and exposing the food product to a vacuum pressure in the range of 45 to 250 Torr (60 to 333 mbar) in the vacuum chamber while irradiating the food product with microwave radiation. This dries the food product and forms a porous structure. The method minimizes or prevents foaming and dries the product at a temperature that prevents burning, while reducing the moisture content to a very low level.

Abstract: A method and apparatus for pasteurizing and drying cannabis plant materials using a microwave-vacuum chamber. The pasteurizing and drying are carried out with no use of ionizing radiation and with rapid drying. Pasteurization is done at a temperature and for a time period that are sufficient to reduce microorganisms to an acceptably low level, while not significantly reducing the psychoactive compounds in the material. In the process, the pressure inside a vacuum chamber is reduced to a first pressure less than atmospheric. The material is maintained in the vacuum chamber at the first pressure at a pasteurizing temperature while irradiating the material with microwave radiation. The pressure is then reduced to a second pressure lower than the first pressure and the material is maintained in the vacuum chamber at the second pressure for a time period at a dehydrating temperature lower than the pasteurizing temperature while irradiating the material with microwave radiation.

Abstract: A method of making a porous, dehydrated food product comprises subjecting a food product to pulsed electric field treatment to form pores in the cell membranes of the food product, freezing the treated food product, and exposing the treated frozen food product to microwave radiation in a vacuum chamber at a pressure that is less than atmospheric and at which the boiling point of water is above 0° C., causing the frozen food product to thaw and water to evaporate to produce the porous, dehydrated product. The process is faster than freeze-drying and consumes less energy. The pulsed electric field treatment does not result in structural damage to the product, despite the thawing of the frozen product during the drying process.

Abstract: A method of making a puffed, dehydrated food product comprises mixing a high amylopectin starch and selected food ingredients to form a dough; forming the dough into pieces; and exposing the dough pieces to microwave radiation at a pressure less than atmospheric to puff and dry the dough pieces, producing the puffed, dehydrated food product. The ingredients may include tomato paste, yogurt, fruit or fruit juice concentrate, fruit puree, vegetable puree, vegetable puree concentrate, coffee, and concentrated soup. The dough may be formed in the absence of starch hydrolysates. The method produces dehydrated food products which incorporate a variety of food ingredients in a matrix that has a puffed, crispy structure.

Abstract: A method of making a porous, crunchy, dehydrated, vegetable, meat or seafood snack product. A piece of vegetable, such as potato, sweet potato, carrot, beet or parsnip, or a piece of meat or seafood, is frozen, forming ice crystals within the piece of food. The frozen piece is exposed to microwave radiation in a microwave-vacuum dehydrator at a vacuum pressure at which the boiling point of water is above 0° C., causing the frozen piece to thaw and water to evaporate from the thawed piece. The evaporation leaves pores that were formed by the ice crystals within the piece of food, resulting in a porous, crunchy, dehydrated snack product.
