Abstract:
An apparatus (20) for microwave vacuum-drying organic materials such as foods and bioactives has a plurality of microwave generators (50) actuated so as to cause interference between their respective microwave streams and evenly distribute the microwave energy across the vacuum chamber (34). The microwave-transparent window (36) in the chamber is arranged so the organic material to be dried is moved across it on a conveyor belt (60) and the microwave energy passing into the chamber (34) immediately encounters the organic materials, thus attenuating the energy and reducing arcing.
Abstract:
An apparatus and method for microwave vacuum-drying of organic materials, such as food products. The apparatus has a microwave vacuum chamber 20, a loading module 36 to load containers 38 of the organic material into the vacuum chamber, a rotatable cylindrical cage 64 in the vacuum chamber for rotating the containers, a piston 114 for moving the rotating containers through the vacuum chamber, and means for unloading the containers of dehydrated material from the vacuum chamber. The apparatus may include an equilibration chamber 150 for cooling the dehydrated material under reduced pressure, and a transfer module 42 to transfer the containers from the vacuum chamber to the equilibration chamber. The apparatus has a microwave transparent window 54 for transmission of radiation into the vacuum chamber, and a gas jet 58, 60, 62 for blowing a stream of gas, such as air or nitrogen, into the vacuum chamber adjacent to the window.
Abstract:
A method of producing a raisin from a grape is disclosed herein. The method includes the step of diffusing a portion of natural sugar out of a grape. The grape has an outer skin enclosing pulp and liquid. The natural sugar is diffused to reduce a sweetness of the grape from an original level of sweetness. The method includes the step of infusing an alternative sweetener into the grape after the diffusing step. The amount of artificial sweetener infused by the grape substantially compensates for the loss of sweetness associated with the portion of natural sugar that was diffused out the grape during said diffusing step. The method includes the step of dehydrating the grape to produce a raisin having a sweetness defined by the combination of natural sugar and alternative sweetener.
Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung eines Heißgetränlcs aus einem Lebensmittel als Ausgangsstoff, welcher aus Tee- oder Kräuterblättern oder Pilzen oder Gemüsen oder einer Mischung hiervon oder Beeren besteht. Der Ausgangsstoff wird nach der Ernte in frischem Zustand zu einem Brei zerkleinert und dieser Brei wird in gasdichte Portionsverpackungen, wie Partionskapseln oder -pads, portioniert abgefüllt, wonach die Portionsverpackungen nach dem Abfüllvorgang eingefroren werden, und dieselben einer solchen Kaltlagerung ausgesetzt werden, welche das Auftauen der gefrorenen Portionsverpackurtgen verhindert und die Portlonsverpackungen erst zum Verbrauch aufgetaut werden.
Abstract:
The invention provides a fruit bar and a method for making a fruit bar. The fruit bar includes primary fruit pieces having a taste and a texture. The texture of the primary fruit pieces is defined at least in part by a hardness and a chewiness and a roughness. The fruit bar also includes secondary fruit pieces combined with the primary fruit pieces. The secondary fruit pieces are of different fruit than the primary fruit pieces. The secondary fruit pieces have a taste and a texture defined at least in part by a hardness and a chewiness and a roughness. In the fruit bar, the taste and the roughness of the first and secondary fruit pieces are different from one another to provide a varied taste and mouthfeel to the consumer. The chewiness and the hardness of the first and secondary fruit pieces are substantially the same to provide a substantial uniformity of bite and chew to the consumer.
Abstract:
Olive powder having particle size less than 0.65mm is produced by a process in which olive paste, derived from whole olives, orujo or alpeorujo, is dried and is comminuted whilst cooling to a temperature below 10°C. The powder has utility for comestible products for human consumption.

Abstract:
The present method is related to a molecular press dehydration method of vegetative tissues using water-soluble polymers in solid-phase as dehydrating agents. The molecular press dehydration method of the present invention is characterized by that dehydration is done by induction of cytorrhysis to vegetative tissues mixed with water-soluble polymers such as PEG, gum arabic, arabinogalactan, egg albumin, milk protein, soybean protein, etc. in its solid-phase. Compared to the conventional dehydration methods, the present method enables to obtain much greater dehydration effects in the amount and the rate, even though a very small amount of polymer substance is used; and the method enables to obtain excellent quality of dehydrated tissues as well as dehydrated exudates; and is environmentally friendly under favor of reduced energy consumption. The dehydrated vegetative tissues are excellent in their storage stability, and flavor and texture after rehydration, and dehydrated exudates are excellent in the concentrated useful components, flavor, and preservation quality. Therefore, the dehydrated vegetative tissues and exudates obtained by using the dehydration method of the present invention may be usefully applied to various fields such as foods and beverages, feeds, cosmetics, medicines, flavorings, agricultural chemicals, coloring agents, etc. according to the characteristics of plants.
