Abstract:
A method for preparing cut and frozen vegetables. The method consists, firstly, in washing the vegetables in order to eliminate any residues of earth or of other substances and materials which may have accumulated during the harvest. In a subsequent step it is necessary to subject the vegetables to mechanical treatment in order to isolate the edible part thereof. By mechanical treatment what is meant is all processes that are useful to isolate the edible part of the vegetable, while removing everything that is not necessary and/or superfluous for dietary purposes. Subsequently the vegetables are cut into strips of thickness comprised between 2 mm and 5 mm and of width comprised between 2 mm and 20 mm, through the use of a cutting device so as to define strips that can have a shape preferably chosen from that of spaghetti, tagliatelle, pappardelle and the like, more generally any long pasta format. At this point the method involves steam-cooking the strips and air-drying them. Once the strips have dried, they are divided into portions corresponding to a preset quantity. Finally, such weighed portions are frozen by way of a freezer to a temperature comprised between -18 °C and -30 °C.
Abstract:
A method for making layers (34) of vegetable leaves (8) comprises the steps of: forming a first uniform bed (6) of vegetable leaves (8) which are laid out flat and randomly superposed; subjecting the first bed (6) of vegetables to a heat treatment; dividing the first bed (6) of heat treated vegetables longitudinally relative to the feed direction (D) to form a plurality of elongate strips (26); superposing the strips (26) over each other to form a second bed (32) composed of a plurality of superposed layers (34) of the first bed (6); cutting the superposed layers (34) to form the second bed (32) into portions (38); and, lastly, deep-freezing the portions (38) made.
Abstract:
Improved brine solutions and uses thereof for uncontaminatedly and/or efficiently freezing items such as foods, and biological samples. In accordance with one embodiment, a brine solution containing a sufficient amount of dye in conferring the solution a distinctive color is used in the freezing process. In accordance with another embodiment, a brine solution containing deionized water is used for improving the freezing efficiency and/or freezing capacity.
Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung tiefgefrorener Kräuter. Grundsätzlich sind die Hersteller von Nahrungsmitteln und dgl. immer bestrebt, Verbesserungen ihrer Produkte zu erreichen. Bei Kräuter ist es immer wünschenswert, ihre Elastizität und Aroma zu erhalten, ihre Haltbarkeit zu verlängern und gleichzeitig die mikrobiologische Belastung der Kräuter deutlich zu reduzieren. Dieses erreicht das erfindungsgemäße Verfahren dadurch, daß die Kräuter in ein leicht kompaktes Gebilde mit einem speziellen Gewicht von 0,01-0,5 g/cm 3 gebracht werden und in der Mikrowelle ggf. unter gleichzeitiger Kühlung und Sauerstoffausschluß behandelt werden, und zwar in einem Temperaturbereich von - 20 bis
Abstract:
The invention relates to a method for continuous gasification with SO 2 gas, using a conveyor belt apparatus that moves along five stations, each station designed for a specific process and having a pre-determined space or "module" where its process is carried out. The conveyor belt is programmed to alternately advance module 1 and stops in the stations for a certain amount of time or a "break" so that the processes can be simultaneously verified in the five stations. The invention uses the instability of the SO 2 gas in relation to water, a phenomenon which is accentuated and accelerated according to its lowest temperature, reaching its maximum potential at 0ºC. The instability of the gas refers to the fact that the gas is absorbed by the water, forming a sulfurous acid solution. According to the method, the fruit is first cooled and is the exposed to the environment so that the humidity condenses thereon, said cold humidity causing a rapid and total absorption of the SO 2 gas which is dispersed in the environment. The method provides for a sequence in three continuous stations: a refrigeration station, a humidifying station and a gasification station.
Abstract:
The invention relates to a method for preparing deep-frozen leaf vegetables, wherein the leaf vegetables are washed, blanched and deep-frozen. It is an object of the present invention to provide a method for preparing deep-frozen leaf vegetables wherein the moisture content of the end product can be precisely controlled within certain bounds.
Abstract:
Food processing methods and a food processing system are provided which minimise microbial growth while an animal, such as a chicken, is processed into food. During processing, the temperature of an animal carcass and the atmosphere surrounding the carcass are controlled by spraying gases and a mixture of ozone and water on the carcass, directing the gases through a passage in a wall to cool a processing area, and flowing the gases into the atmosphere surrounding the carcass. Preferably, the gases include ozone and cryogenic gases recycled from a cryogenic freezer. The system uses a reduced amount of fresh water by recycling water used during food processing.
