Abstract

The tofu in a film packaging introduced into a gastight, closable pasteurizing system with a back pressure, is claimed. The system: is filled with water; includes a steam-powered pressure vessel, which is configured for thermal treatment of substances at high pressure; and is turned on, heated to a water temperature or a boiler temperature of 110[deg] C and operated at a pressure of 1-2 bars. The boiler temperature is maintained until the tofu reaches to an internal temperature of 104-115[deg] C. The boiler temperature and the internal temperature are further maintained for 30-50 minutes. The tofu in a film packaging introduced into a gastight, closable pasteurizing system with a back pressure, is claimed. The system: is filled with water; includes a steam-powered pressure vessel, which is configured for thermal treatment of substances at high pressure; and is turned on, heated to a water temperature or a boiler temperature of 110[deg] C and operated at a pressure of 1-2 bars. The boiler temperature is maintained until the tofu reaches to an internal temperature of 104-115[deg] C. The boiler temperature and the internal temperature are further maintained for 30-50 minutes, and a cooling process is carried out under pressure until the internal temperature is reached to less than 80[deg] C. An independent claim is included for a method for extending the shelf life of tofu.

Description

[0001] Die gegenständliche Erfindung, die von der Feel Good Handels-GmbH angemeldet wird, gilt für das Produkt Tofu. The subject invention, which is filed by the Feel Good Handels GmbH, applies to the product tofu.

[0002] Traditionell wird zur Haltbarmachung in der Tofuverarbeitung die Methode der Pasteurisierung eingesetzt. Diese Vorgangsweise ermöglicht eine gesicherte Mindesthaltbarkeit von ca. sechs Wochen, wobei die Produkte zwischen 4 °C bis 6 °C gelagert werden müssen. Traditionally, the method of pasteurization is used for preservation in tofu processing. This procedure allows a guaranteed minimum shelf life of about six weeks, with the products between 4 ° C to 6 ° C must be stored.

[0003] Eine längere Haltbarkeit und auch eine Lagerung ausserhalb von Kühlregalen erfordern in der Lebensmittelverarbeitung den Prozess der Sterilisation. Diese Sterilisation ist auch bei Tofu anwendbar, allerdings nur dann, wenn sich der frische Tofu im Glas oder in einer Konservendose befindet. A longer shelf life and storage outside of refrigerated shelves require in food processing the process of sterilization. This sterilization is also applicable to tofu, but only if the fresh tofu is in the glass or in a tin can.

[0004] Der Lebensmittelhandel möchte jedoch, dass Tofu in seiner traditionellen Folienverpackung wie im Kühlregal üblich angeboten wird, wobei die Haltbarkeit länger als sechs Wochen sein soll und die Aufbewahrung ausserhalb des Kühlregals erfolgen sollte. Eine Sterilisation zerstört das Produkt, wenn es nicht im Glas oder in der Dose aufbewahrt ist. The grocery trade, however, would like tofu to be offered in its traditional foil packaging, such as the refrigerated shelf, with shelf life being longer than six weeks and storage outside of the refrigerated shelf. Sterilization destroys the product if it is not stored in the jar or can.

[0005] Der Antragstellerin ist es nun gelungen, eine ungekühlte Haltbarkeit zu erzeugen und somit Tofu auch in der Folie Kunden anzubieten. The applicant has now been able to produce an uncooled shelf life and thus offer tofu in the film customers.

[0006] Tofu wird in der Folienverpackung in einen Druckbehälter, das ist eine Pasteurisierungsanlage mit Gegendruck, eingebracht. Tofu is in the film packaging in a pressure vessel, which is a pasteurization with counter pressure introduced.

[0007] Die thermische Behandlung der Produkte erfolgt wegen des typischen Abschlusses gegenüber der umgebenden Atmosphäre chargenweise (Batch-Betrieb). Dazu ist der Druckbehälter mit Schnellverschlüssen ausgerüstet, die gegenüber geflanschten Druckbehälteröffnungen ein wesentlich schnelleres Öffnen und Schliessen des Druckbehälters ermöglichen. The thermal treatment of the products is carried out batchwise because of the typical conclusion with respect to the surrounding atmosphere (batch operation). For this purpose, the pressure vessel is equipped with quick-release closures, which allow a much faster opening and closing of the pressure vessel compared to flanged pressure vessel openings.

[0008] Hierauf wird das Gerät eingeschalten und bis zu einer Wassertemperatur (Kesseltemperatur) von 110 °C aufgeheizt. Während des gesamten Vorganges ist ein Druck zwischen 1 und 2 bar zu erhalten. Then the device is turned on and heated to a water temperature (boiler temperature) of 110 ° C. During the entire process, a pressure between 1 and 2 bar is obtained.

[0009] Die Kesseltemperatur wird gehalten bis das Produkt die Kerntemperatur von zumindest 104 °C erreicht. Die Kesseltemperatur von 110 °C, sowie die Kerntemperatur zwischen 104 °C und 115 °C werden bis zu 50 Minuten gehalten, danach kommt es zu einem Abkühlvorgang unter Druck bis eine Kerntemperatur < 80 °C erreicht ist. Anschliessend werden die Produkte entnommen und gelagert. The kettle temperature is maintained until the product reaches the core temperature of at least 104 ° C. The kettle temperature of 110 ° C, and the core temperature between 104 ° C and 115 ° C are held for up to 50 minutes, then it comes to a cooling process under pressure until a core temperature <80 ° C is reached. Subsequently, the products are removed and stored.

[0010] Das Produkt kann dann in handelsüblichen Verpackungsfolie ungekühlt angeboten werden, wobei eine Haltbarkeit des Produktes von bis zu 12 Monaten (MHD = Mindesthaltbarkeitsdatum) gegeben ist. The product can then be offered uncooled in commercial packaging film, with a shelf life of the product of up to 12 months (best before date) is given.

[0011] Es wird beantragt, folgenden Vorgang zu schützen: It is requested to protect the following process:

[0012] Tofu wird mit einer Folienverpackung in eine Pasteurisierungsanlage mit Gegendruck eingebracht. Diese Anlage ist ein gasdichtverschliessbarer, mit Wasser befüllter oder mit Dampf betriebener Druckbehälter, der für die thermische Behandlung von Stoffen im Überdruckbereich eingesetzt wird. Tofu is introduced with a foil package in a pasteurization plant with back pressure. This plant is a gas-tight, water-filled or steam-operated pressure vessel used for the thermal treatment of substances in the overpressure area.

[0013] Daraufhin wird das Gerät eingeschaltet, bis zu einer Wassertemperatur, schliesslich Dampftemperatur (Kesseltemperatur) von 110 °C aufgeheizt. Während des gesamten Vorganges ist ein Druck zwischen 1 und 2 bar zu erhalten. Then the device is turned on, heated to a water temperature, finally steam temperature (boiler temperature) of 110 ° C. During the entire process, a pressure between 1 and 2 bar is obtained.

[0014] Die Kesseltemperatur wird gehalten, bis das Produkt die Kerntemperatur von mindestens 104°C erreicht. Die Kesseltemperatur von 110 °C sowie die Kerntemperatur zwischen 104 °C und 115 °C werden 30 bis 50 Minuten gehalten, danach kommt es zu einem Abkühlvorgang unter Druck bis eine Kerntemperatur < 80 °C erreicht ist. The kettle temperature is maintained until the product reaches the core temperature of at least 104 ° C. The kettle temperature of 110 ° C and the core temperature between 104 ° C and 115 ° C are held for 30 to 50 minutes, then it comes to a cooling process under pressure until a core temperature <80 ° C is reached.

[0015] Das Verfahren dient zur Verlängerung der Haltbarkeit von Tofu, das in Folienverpackung ungekühlt gelagert wird. The method serves to extend the shelf life of tofu, which is stored uncooled in foil packaging.

[0016] Die Erfindung ist bereits unter der Nummer 202 011 004 978 beim Patentamt in Deutschland und unter der Nummer 11 716 beim Patentamt in Österreich als Gebrauchsmuster registriert. The invention is already registered under the number 202 011 004 978 at the Patent Office in Germany and under the number 11 716 at the Patent Office in Austria as a utility model.

[0017] Durch ein Patent können Herstellungsverfahren geschützt werden, auf der Homepage des Eidgenössischen Institutes für Geistiges Eigentum findet sich als Beispiel für ein Herstellungsverfahren, ein neues Verfahren zur Trocknung von Lebensmitteln. Das gegenständliche Patent ist also durchaus vergleichbar mit dem als Beispiel angegebenen Patent auf der Website. By a patent manufacturing processes can be protected, on the homepage of the Federal Institute of Intellectual Property is an example of a manufacturing process, a new process for drying food. The subject patent is thus quite comparable to the patent given as an example on the website.
