Definitions

  • the present invention relates to a device arranged to bring about a decreased degradation of food placed in a gastight food package.
  • the device comprises a gas conductor adapted to be connected between at least one gas supply and the food package for changing the composition of the gas inside the food package to a composition with food preserving qualities.
  • Food may deteriorate due to several different mechanisms, such as bacterial growth, oxidation of fats, dehydration, mould etc.
  • One method used within the food industry to prolong the durability of foods is to store the food in a gastight package and to change the composition of the gas surrounding the food to a gas with food preserving qualities.
  • gases usually comprise mixtures of N 2 , O 2 and CO 2 with various contents depending on the food.
  • the mechanisms behind food preservation are well known in the art.
  • N 2 is usually used as an inert gas for reducing the presence of other gases, such as oxygen
  • CO 2 dissolves in the water bound in food forming carbon acid, which lowers pH and decrease growth of bacteria and mould
  • O 2 is used to reduce browning of for example meat.
  • One object of the present invention is to further decrease the degradation of foods in order to increase the time available before consumption.
  • a consumer may store food in a food preserving atmosphere, wherein the durability of the food is increased considerably.
  • Normal consumer behaviour concerning the handling of foods comprises that the consumer opens a food package, either for direct consumption or for cooking, which simultaneously let out any food preservative gas, and then continues to store either or both of the unused food or its cooked counterpart. Hitherto, most foods have been well preserved in an unopened package, but as soon as a consumer breaks the seal the food degrades swiftly, even if stored in a refrigerator or freezer.
  • the consumer may store food from an opened package or cooked food in a food preservative atmosphere, so that at least a part of the long durability date of an unopened package may be retained.
  • the use of food preservative gas by a consumer also gives the advantage of a slower degradation of nutrition content in the food.
  • Another advantage is in the event that the food is to be stored during a longer period than possible in a refrigerator in a normal atmosphere, but not as long as possible in a freezer. This may happen for example when preparing food boxes. In this case the consumer may store the food in a food preservative atmosphere in the refrigerator instead, so that it is not necessary to freeze the food only to be heated shortly afterwards.
  • the device should be user friendly and also sufficiently small, so that the device may be positionable and used in a kitchen by the kitchen personnel.
  • the device is adapted for household use, wherein the device is adapted in size, weight and shape so that the device is positionable and usable in a household kitchen.
  • the device should then be user friendly and also sufficiently small, so that the device may be positionable and used in a household kitchen by a normal consumer.
  • the device is adapted for use in a restaurant, wherein the device is adapted in size, weight and shape so that the device is positionable and usable in a restaurant kitchen.
  • the device is adapted to be used by a user without any training in the field of preservative gases.
  • the device is adapted for filling a food package with at least one predefined gas composition.
  • the device is arranged to allow selection of one of at least two predefined gas compositions for filling a food package.

  • the device is arranged for the consumer to manually connect and disconnect the conductor to the food package.
  • the device is also arranged for the consumer to manually select a gas mixture and to induce the device to begin the gas filling sequence.
  • Automated operation usually gives a higher filling rate, but also makes the device more cumbersome, and also puts higher demands on training.
  • a device adapted for household use has not the same need of a high production rate, and thus a manually operated device is advantageous.
  • the device is preferably adapted so that the capacity of the device is lower than within the food industry.
  • the device is adapted for filling food packages in batches.
  • the batch size is no more than three food packages simultaneously, and preferably no more than one food package per batch.

  • the device is adapted to supply gas having food preservative characteristics to the interior of the food package.
  • the device is adapted to fill the food package with a food preservative gas comprising N 2 and CO 2 .
  • the gas may also contain a small content of O 2 , either from a gas supply within the device, or more preferably, by retaining a small amount of the previous air inside the package.
  • the device is adapted to fill the package with the food preservative gas so that the gas surrounds the food and occupies the space around the food.
  • the gas decreases oxidation of fat and meat, decreases mould and bacterial growth, and decreases discolouring of the food.
  • the device is adapted to fill the package with gas up to a gas pressure of at the most 2.5 atmospheres, preferably no more than 1.5 atmospheres.
  • food is primarily intended food for eating, such as solid foods and liquid foods as soups.
  • the term food is not intended to include beverages, even though it may be possible to use the device for beverages as well.
  • the device is shaped into one unit, and preferably also adapted to contain the gas supply.

  • the mouthpiece 43 comprises a sleeve adapted to snugly fit into a notch arranged round the valve 47, so that the connection between the mouthpiece 43 and the first valve 47 is both gastight and secure. After filling the package with food preservative gas the mouthpiece is disconnected from the valve 47.
  • the mouthpiece may also be disconnected from the mouthpiece mounting 41, in the event that another type of food-package is to be filled.
  • a second food-package 49 comprises a bag of soft, but thick, plastic, so that the bag is gastight when closed.
  • a second mouthpiece 51 comprises a long snout adapted to be inserted into the bag 49 through its opening.
  • the bag is folded around the snout so that the connection is gastight. Since the desired pressure within the bag is not particularly high, it is possible to obtain a gastight connection by simply folding the bag around the snout.
  • the bag may be held onto the snout either by hand or with for example a rubber band. The bag is then filled with gas through the mouthpiece 51.
  • the invention is not limited to the examples shown above, but may be varied freely within the framework of the following claims.
  • the term conductor is intended to cover all forms of conductors, chambers, pipes, hoses etc, having the ability to conduct gas.
  • the term conductor is also intended to include assemblies of several connected gas conducting pieces.
  • the food package may be made in metal, plastic, cloth, or any other suitable material, and may be either hard or soft and may or may not contain valves.
  • a large number of different mouthpieces may be conceived for fitting with different packages or containers, such as a mouthpiece for connecting with a bottle of beverage.
  • the device may contain a gas supply with a ready-made mixture of food-preservative gas instead of two gas supplies, which need to be mixed.
  • the device may contain three or more gas supplies, for example an oxygen supply, and may contain any number of additional conductors, valves etc.
