Abstract

The package for fruit and vegetables, especially asparagus, comprises a self-supporting tray (1) fitted with a cover film (2) with an airtight seal. The film or tray has perforations (3), the ratio of the total surface of the perforations to the surface of the tray being 0.005 - 0.25.

Description

Die Erfindung betrifft eine Verpackung für Obst und Gemüse, insbesondere Spargel, umfassend eine selbsttragende Schale und eine mit dieser luftdicht verbundene Folie.The invention relates to a packaging for fruits and vegetables, in particular asparagus, comprising a self-supporting shell and a film associated with this airtight.

Wenn in einer solchen herkömmlichen Verpackung Obst oder Gemüse verpackt wird, dann befindet sich dieses unter einem totalen Luftabschluß. Das Fehlen von jeglichem Luftaustausch begünstigt jedoch das Wachstum von Schimmelpilzen. Beispielsweise verschimmelt Spargel bereits nach 2 Tagen, wenn er absolut luftdicht verpackt wird. Der Spargel ist somit verdorben und unverkäuflich.If fruit or vegetables are packaged in such a conventional packaging, then this is under a total exclusion of air. The lack of any air exchange, however, favors the growth of molds. For example, asparagus molds already after 2 days, if it is packed absolutely airtight. The asparagus is thus spoiled and unsalable.

Aus diesem Grund werden Obst und Gemüse üblicherweise nicht verpackt, sondern in Tüten oder in Holzschalen angeboten. Da in diesem Fall ein sehr großer Luftaustausch möglich ist, kann das Obst oder Gemüse jedoch rasch austrocknen. Beispielsweise wird ein in einer offenen Schale bei 20°C gelagerter Spargel bereits nach 4 Stunden holzig, und es bildet sich Rostschimmel. Ein solcher Spargel wird vom Verbraucher aus Gründen der Optik wie auch des Geschmacks nicht akzeptiert.For this reason, fruits and vegetables are usually not packaged, but offered in bags or in wooden bowls. However, since in this case a very large exchange of air is possible, the fruit or vegetables can dry out quickly. For example, an asparagus stored in an open dish at 20 ° C becomes woody after just 4 hours, and it forms rust mold. Such asparagus is not accepted by consumers for reasons of appearance or taste.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Verpackung dahingehend zu verbessern, daß sich Obst und Gemüse, insbesondere Spargel ohne Qualitätseinbuße über einen längeren Zeitraum lagern läßt.The invention has for its object to improve the generic packaging to the effect that can store fruits and vegetables, especially asparagus without loss of quality over a longer period.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Schale oder die Folie perforiert ist, wobei das Verhältnis zwischen der Gesamtfläche der Perforationsöffnungen und der Fläche der Schale oder der Folie 0,005 bis 0,25 beträgt.According to the invention this object is achieved in that the shell or the film is perforated, wherein the ratio between the total area of the perforation openings and the surface of the shell or the film is 0.005 to 0.25.

Es hat sich überraschender Weise gezeigt, daß es zwischen den beiden Extremen - totaler Luftabschluß bzw. unbehinderter Luftaustausch - mit den jeweiligen nachteiligen Folgen für die Haltbarkeit des Verpackungsgutes einen Zwischenbereich gibt, bei dem einerseits ein geringer Feuchtigkeitsverlust des Verpackungsgutes erreicht und andererseits eine Schimmelbildung verhindert wird.It has surprisingly been found that there is an intermediate area between the two extremes - total air separation or unimpeded air exchange - with the respective adverse consequences for the durability of the packaged goods, on the one hand achieved a low moisture loss of the packaged goods and on the other hand mold is prevented ,

In der erfindungsgemäßen Verpackung kann geschälter Spargel bei geringer Kühlung 7 Tage ohne erkennbare Qualitätsminderung gelagert werden, ungeschälter Spargel sogar 14 Tage. Eine Kühlkette kann vorübergehend unterbrochen werden, ohne daß die Gefahr einer Austrocknung des Verpackungsgutes besteht. Dies bedeutet mehr Chancen im Lebensmitteleinzelhandel hinsichtlich Vorproduktion und Lagerung. Dies ist insbesondere bei Spargel bedeutsam, weil die Saison dadurch verlängert wird.In the packaging according to the invention, peeled asparagus can be stored for 7 days without noticeable reduction in quality with little cooling, and unpeeled asparagus even for 14 days. A cold chain can be temporarily interrupted without the risk of dehydration of the packaged goods. This means more opportunities in food retailing in terms of pre-production and storage. This is particularly important for asparagus because the season is extended.

Für die Lösung der erfindungsgemäßen Aufgabe ist es unerheblich, ob die Folie oder die Schale perforiert ist. Aus herstellungstechnischen Gründen ist es jedoch vorteilhafter, die Folie zu perforieren.For the solution of the object of the invention, it is irrelevant whether the film or the shell is perforated. For manufacturing reasons, however, it is more advantageous to perforate the film.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten bevorzugten Ausführungsbeispiels näher erläutert.The invention will be explained in more detail with reference to a preferred embodiment shown in the drawing.

Die einzige Figur der Zeichnung zeigt einen schematischen Querschnitt durch eine Verpackung. Diese Verpackung umfaßt eine selbsttragende Schale 1 aus einem luftundurchlässigen Material. Die Schale 1 kann aus Kunststoff, wie z. B. Polypropylen tiefgezogen sein. Nachdem das Verpackungsgut in die Schale 1 eingebracht wurde, wird eine Folie 2 mit einem umlaufenden Flansch der Schale 1 luftdicht verbunden, beispielsweise verklebt oder verschweißt. Die Folie 2 ist mit einer Vielzahl von Öffnungen oder Perforationen 3 versehen, die in einer oder mehreren Reihen angeordnet sein können. In der Zeichnung sind die Öffnungen 3 aus darstellerischen Gründen sehr stark vergrößert.The sole figure of the drawing shows a schematic cross section through a package. This packaging comprises a self-supporting shell 1 made of an air-impermeable material. The shell 1 may be made of plastic, such as. As polypropylene be deep drawn. After the packaged product has been introduced into the tray 1, a film 2 is airtight connected to a peripheral flange of the shell 1, for example glued or welded. The film 2 is provided with a plurality of openings or perforations 3, which in one or several rows can be arranged. In the drawing, the openings 3 are greatly increased for illustrative reasons.

Mit einer solchen Verpackung wurden mehrere Versuche mit Folien durchgeführt, die sich hinsichtlich der Größe und Anzahl der Öffnungen unterschieden. In allen Fällen wurde eine Schale aus Polypropylen mit den Abmessungen 190 x 144 x 83 mm und eine Deckelfolie aus Polyethylen mit einer Stärke von 65 µm und einer Fläche von 27.360 mm2 verwendet. In diesen Verpackungen wurde frisch geschälter Spargel aus dem Anbaugebiet Schrobenhausen verpackt. Dabei wurden 6 unterschiedlich ausgebildete Folien verwendet, wie aus der nachfolgenden Tabelle hervorgeht.With such a package, several trials were made with films that differed in size and number of openings. In all cases, a 190 x 144 x 83 mm polypropylene tray and a 65 micron polyethylene lidding sheet of 27,360 mm 2 were used. Freshly peeled asparagus from the Schrobenhausen region was packed in these packages. In this case, 6 differently formed films were used, as can be seen from the table below.

Bei allen Proben waren die Spargel nach 14 Tagen optisch einwandfrei, lediglich bei den Proben 3 und 4 war eine geschmackliche Qualitätsminderung zu erkennen.

For all samples, the asparagus was visually perfect after 14 days, only in the samples 3 and 4 was a taste quality reduction can be seen.
