Description
- The present invention concerns a method and the relative plant for packaging fresh food products, such as fruit and vegetables. In particular, the present invention is used for packaging fresh fruit and vegetables, for example apples, pears, oranges, carrots, bananas and others, intended for individual distribution in automatic distributors in public places.
- Fresh food products are known, such as fruit and vegetables, commonly sold retail and in large scale retail outlets, loose or disposed on containers or boxes made of plastic, wood or cardboard.
- The products are generally sold complete with the peel which is removed, if necessary, by the consumer when they are eaten.
- The products are necessarily sold with the peel due to the fact that the desired freshness of the product on the counter must be guaranteed at least for some days.
- In fact, if they are preserved with the peel in a cool dry place, the products keep their organoleptic properties substantially unchanged for some days whereas, if they have no peel, they deteriorate in the space of a few hours, due to the effect of the oxidation of the hydroquinones inside them.
- The habit of having quick snacks with fresh, natural products is becoming more and more common, even outside the house, as an alternative to the high-caloric food that is typical of long-preservation snacks with additives, produced industrially.
- However, fresh products, like fruit and vegetables, for example apples, pears, carrots, and others, are difficult to distribute individually in traditional automatic snack distributors.
- This is due to the fact that, since it is necessary to guarantee a practical and speedy consumption for the user, also considering that natural products must be preserved with their peel, if they were to be distributed in automatic distributors, this would entail a simultaneous distribution of utensils in order to remove the peel at the moment of consumption
- Furthermore, if the product is peeled, there are problems relating to the juice which, to a lesser or greater extent, can come out of the product and dirty the user's hands or stain his/her clothes.
- The need to distribute fresh products such as fruit and vegetables individually is even more prevalent in school institutions, since it is preferable that children's diet should include fruit and vegetables for a correct intake of fibers and vitamins, and that the consumption of industrially produced quick snacks should be reduced. Children, however, are unable to use cutting utensils efficiently and with due attention in order to remove the peel from fruit and vegetables and are therefore obliged to eat such products with the peel. Very often, even if washed, the peel has chemical products used in agriculture, wax or microorganisms.

US-A-4,835,942 discloses a seafood vacuum-pack system for producing a vacuum packed shrimp pack. - Purpose of the present invention is to perfect a method, and the relative plant, to distribute individually fresh food products by means of automatic distributors, guaranteeing both that the organoleptic properties of the natural fresh product are maintained without using preservatives and/or additives of various types, and also that the products can be consumed in a practical and rapid manner, substantially for every type of user.
- The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
- The present invention is set forth and characterized in the independent claims, while the dependent claims describe other characteristics of the invention or variants to the main inventive idea.
- In accordance with the above purpose, a method for packaging fresh food products, such as fruit and vegetables provided on the outside with a protective peel, comprises at least a peeling step, in which the peel is removed from said product.
- According to a characteristic feature of the present invention, after the peeling step, the peel is replaced in its functions of protecting and preserving the product with at least a coveringfilm made of thermo-formable material by means of at least a covering step, in which said at least a film of material, advantageously but not necessarily totally or partly transparent, is associated with the external surface of the food product. Said covering step comprises a first shaping sub-step, in which a first film in the form of a strip made of thermo-formable material is shaped so as to define a seating having a shape correlated to the product, a second positioning sub-step in which said product is deposited in said seating, and a third covering sub-step in which a second film in the form of a strip made of thermo-formable material is positioned above the first film so as to cover the whole surface of the product. Moreover, the method of the present invention comprises a molding step in which the film is made to adhere to the external surface of the food product by depositing said second film so as to assume a shape correlated to the product so that the bulk of the package is substantially equal to that of the non-packaged product.
- With this method we obtain a natural product in which the film replaces the peel in its functions of protecting and preserving the product but, unlike the peel, it is easily removed without the aid of utensils. Moreover, the bulk of the package is substantially equal to that of the non-packaged product, and therefore suitable for the limited spaces of the compartments of automatic distributors.
- In this way it is also possible to package products substantially spherical in shape, without the film forming bends and overlapping on the surface of the product.
- According to a variant, in the case of thermo-formable film, after the molding step, a step of heat-retraction is provided, in which the film is made to shrink so as to adhere further to the surface of the product.
- This solution allows to increase further the adherence of the film to the product, with a final result that simulates the peel.
- According to a variant, before the covering step, the present invention comprises a step of anti-oxidizing treatment, in which the peeled product is treated with an anti-oxidant solution in order to delay browning and to increase duration.
- According to a variant, the molding step provides a sub-step to create a vacuum, in which the air between the film and the product is taken in.
- This operation, eliminating or reducing the presence of oxygen in contact with the product, reinforces the effect of the anti-oxidizing treatment and allows to further extend the duration of the product.
- According to another variant, after the vacuum step, the molding step comprises a sealing step in which the film is made solid in a closing zone, and a trimming sub-step in which the film is trimmed along the line of solidarization.
- Solidarization makes the package hermetic, thus preventing any contamination of the product by external agents and also prevents any air from entering.
- According to a variant, before the step of anti-oxidizing treatment, the method comprises a cutting step, in which the product is cut into portions of a predefined shape, for example segments or round pieces, which are kept together to form the original shape of the product.
- This solution is particularly advantageous in the case of products intended for distribution in public places, such as for example hospitals, rest homes and schools, frequented by consumers who need to be able to eat the product in pieces that are easily picked up by hand, and not bitten.
- According to another variant, the film is a color that reproduces the appearance of the packaged food product. In this way, the product is more easily recognizable by the consumer and is aesthetically more pleasing.
