Description

Die vorliegende Erfindung bezieht sich auf einen in Lebensmittelverpackungen integrierten Frischetester für Lebensmittel.The The present invention relates to a food packaging integrated freshness tester for Food.

Industriell gefertigte Lebensmittel werden vom Hersteller mit einem Mindesthaltbarkeitsdatum in den Verkauf gebracht. Dieses Mindesthaltbarkeitsdatum trifft laut Definition eine verallgemeinerte und pauschalisierte Aussage über die Haltbarkeit eines Lebensmittels.Industrial Manufactured food is supplied by the manufacturer with a best before date brought the sale. This best before date is loud Definition of a generalized and generalized statement about the Shelf life of a food.

Das Mindesthaltbarkeitsdatum trifft allerdings keine Aussage über das einzelne, vom Verbraucher bevorratete Lebensmittel, insbesondere, wenn die Lagerung in folge vom Hersteller nicht vorhergesehenen Temperaturen (z. B. Einfrieren oder Lagerung oberhalb der empfohlenen Temperatur) stattfindet oder die Lebensmittelverpackung geöffnet wurde und das Lebensmittel bereits mit der Atmosphäre in Kontakt kam.The Best before date, however, does not say anything about the individual foodstuffs held by the consumer, in particular, when storage as a result of temperatures not anticipated by the manufacturer (eg freezing or storage above the recommended temperature) or the food packaging has been opened and the food already with the atmosphere came into contact.

Der vorliegenden Erfindung liegt das technische Problem zu Grunde, eine Aussage über den aktuellen Haltbarkeits-/Frische-Zustands eines Lebensmittels zu treffen und diesen am Produkt anzuzeigen.Of the The present invention is based on the technical problem, a Statement about the current shelf-life / freshness status of a food to meet and display this on the product.

Die Erfindung des Frischetesters richtet sich auf einen Indikator (pH-Tester), der in einem Lebensmittelbehältnis integriert ist und durch Reaktion mit dem Lebensmittel dem Konsumenten bei der Burteilung über den aktuellen Zustand des Lebensmittels helfen kann.The Invention of the freshness tester is directed to an indicator (pH tester), in a food container is integrated and by reaction with the food the consumer at the Burteilung over can help the current state of the food.

Der erfindungsgemäße Indikator in einem Lebensmittelbehälter zeichnet sich dadurch aus, dass er dem Konsumenten auf einen Blick den Zustand eines Lebensmittels anzeigt.Of the Inventive indicator in a food container is characterized by the fact that it shows the consumer at a glance indicates the condition of a food.

Dieses gilt insbesondere für die Verwendung von Getränkeverpackungen und Lebensmittelverpackungen aus Kartonage sowie Getränkebehältnisse aus Glas oder Lebensmittelverpackungen aus Glas oder Kunststoff, z. B. PET.This especially applies to the use of beverage packaging and food packaging made of cardboard and beverage containers Glass or food packaging of glass or plastic, e.g. Eg PET.

Die Frischeanzeige ist für alle Milchprodukte z. B. Frischmilch, haltbare Milch, Jogurt, Käse, Quark, Sahne, Buttermilch sowie weitere Getränke z. B. Fruchtsäfte und Fruchtkonserven anwendbar und auf alle anderen Produkte oder Lebensmittel bei denen der pH-Wert einen Indikator für deren Verwendbarkeit zum Konsum darstellt.The Freshness indicator is for all dairy products z. Fresh milk, yoghurt, cheese, quark, Cream, buttermilk and other drinks z. B. Fruit juices and Preserved fruit and applicable to all other products or food in which the pH is an indicator of their usability for Consumption represents.

Weiterhin kann der Frischetester auch bei nicht industriell gefertigten Lebensmittel, z. B. von Bauerhöfen abgefüllte Milch, als Applikation/Indikatorklebepunkt an allen Lebensmittelbehältnissen einzeln nachträglich aufgebracht werden.Farther the freshness tester can also be used for non-industrial foods, z. B. of farms bottled Milk, as an application / indicator cell point on all food containers individually afterwards be applied.

Der erfindungsgemäße Indikator basisiert auf der Verwendung der Wirkungsweise von Milchsäure-Indikatorstäbchen bzw. Säure-Indikatorstäbchen (pH-Tester). Indikatorstäbchen sind bereits allgemein bekannt und in unterschiedlichen Ausführungen, z. B. unterschiedliche pH-Bereiche und lebensmittelecht, verfügbar.Of the Inventive indicator based on the use of the mode of action of lactic acid indicator strips or Acid indicator sticks (pH tester). indicator strips are already well known and in different versions, z. As different pH ranges and food safe, available.

Die indizierende Substanz kann in einem ph-Streifen, der in eine Verpackung integriert ist oder durch eine Wirkstoff-Verbindung, als Klebepunkt oder in einem Kunststoff oder Lackgemisch, mit der Verpackung oder deren Anbauteilen (z. B. Deckel oder Ausgießer) verbunden sein. Für nicht industrielle Abfüllungen kann der Indikator mittels Klebepunkt oder andere Weise auf allen Verpackungen und Gefäßen befestigt werden.The indexing substance may be in a ph strip in a package is integrated or through an active ingredient compound, as a glue point or in a plastic or varnish mixture, with the packaging or their attachments (eg lid or spout) may be connected. For not industrial bottlings the indicator can be made by glue dot or other way at all Attached packaging and containers become.

Durch einen kontinuierlichen und/oder initiativen Kontakt mit dem Lebensmittel sind die abzulesenden Farbwerte über eine auf der Verpackung zusätzlich angebrachten Skala (1-2 und 2-2) eindeutig und im Moment vor dem Verbrauch des Lebensmittels abzulesen.Through a continuous and / or initiative contact with the food, the color values to be read are displayed by means of a scale additionally attached to the packaging ( 1-2 and 2-2 ) clearly and at the moment before the consumption of the food read.

Der angezeigte und überwachte ph-Wert im Verhältnis zum Verfall des Lebensmittels ist dem jeweiligen Produkt angepasst, da Frischmilch in einem anderen ph-Bereich als Frisch gilt als z. B. Buttermilch oder andere Produkte.Of the displayed and monitored ph value in proportion the deterioration of the food is adapted to the respective product, because fresh milk in a different pH range than fresh is considered z. B. buttermilk or other products.

Der Indikator im Sichtfester (1-1) steht in ständigem Kontakt mit dem Lebensmittel und ist vor einer Abwaschung der Indikator-Substanz durch eine zum Beispiel semipermeable Folie geschützt.The indicator in the visible solid ( 1-1 ) is in constant contact with the food and is protected from being washed off the indicator substance by, for example, a semi-permeable film.

Der Indikatorpunkt im Ausgießer (2-1) kommt beim ersten Öffnen der Lebensmittelverpackung mit dem Lebensmittel in Kontakt und beginnt somit seine Reaktion. Das verbleibende Lebensmittel in der Verpackung hat die gleiche Verfallgeschwindigkeit bzw. Verfallszustand wie die Lebensmittelreste, die am Ausgießer durch das ausgießen verbleiben, und somit zeigt der Indikatorpunkt am Ausgießer den gleiche pH-Wert an, wie das Restprodukt.The indicator point in the spout ( 2-1 ) comes in contact with the food the first time the food packaging is opened and thus begins its reaction. The remaining foodstuff in the package has the same rate of deterioration as the food remains left on the spout by pouring, and thus the indicator point on the spout indicates the same pH as the residual product.

1-1 zeigt eine Aufrissdarstellung eines Lebensmittelbehälters (in diesem Fall einen Getränkekarton) der einen erfindungsgemäßen Indikator mittels Sichtfenster als Ausführungsbeispiel. 1-1 shows an elevational view of a food container (in this case a beverage carton) of an indicator according to the invention by means of viewing window as an embodiment.
