designation:

Bacterial growth inhibiting food storage system.

Container for storing food which is stored by means of associated vacuum packing pump and associated pressure bottle containing food glass which is added after proper vacuum is reached. The container and / or plastic bag is for insertion into all types of refrigerators.

Field of application

Existing food storage is commonly known as refrigeration / freezer cabinets.

For insertion into existing refrigerators of all makes, invention # 0005 is characterized by being a container in which can be evacuated in the container for storing various foods, and / or evacuated in specially made plastic bags with hose and studs for evacuation of the bag. .

A connection device is mounted on the rear of the container, so that the container can be connected to a pump / filling station, which contains the following: A small vacuum pump which allows to evacuate the container and / or bags down to a given vacuum through the hose, studs and valves. , whereupon a valve permits a special food gas to be blown from a small pressure bottle (about 200 bar) through the safety valve to the container for a given time and to a given pressure.

The station can empty and refill the specially designed bags separately from the storage container mentioned. That is, both systems can be used independently. Foods stored in this container and / or bag referred to above give the foods an extended shelf life of up to 5 times normally. This extended shelf life ensures that the food can be used for a much longer time and that the food is purely bacteriologically far better than with normal storage in a refrigerator or other where the temperature is 0-5 degrees Celsius.

Prior art

The disadvantages of existing storage of various perishable foods stored in refrigerators are that these products are often packed in protected atmosphere or vacuum packed and that the shelf life of the food is reduced the second the packaging is broken due to bacterial growth due to the atmospheric air. Organic products that have a low shelf life will also degrade fairly quickly in ordinary atmosphere.

The general shelf life of food will under normal circumstances be extended in the commonly known systems such as refrigerators and refrigerators, where the temperature is kept at 0-5 degrees Celsius. But the presence of aphid where the products are stored will always trigger bacterial growth in the foods and will limit the shelf life.

Storing certain foods in an oxygen-free atmosphere may pose a risk of growth of undesirable microorganisms.

Due to these conditions, there is no commercial system that can handle end-user food storage needs in order to extend food shelf life, without using chemical preservatives and antioxidants.

The nve technique

The new technique is characterized by the use of oxygen-tight packaging of food in containers and / or special plastic bags in which the oxygen pressure is low. The packaging container and / or plastic bag used must have an oxygen permeability of a maximum of 4 ml / day / m2, measured under standard conditions at 23 ° C.

This prolongs the shelf life of everyday foods. Furthermore, bacterial growth is generally diminished in these foods, which are stored refrigerated in refrigerators (+5) - when various packaging packages are broken. The advantages of invention 0005 are that cold cuts and other meats as well as vegetables and other perishable foods where the packaging is broken can again be packed and / or stored under controlled conditions, as when they were first packed. This causes bacterial growth to be kept to a minimum, thereby extending the shelf life of the food, as well as keeping the food to a minimum bacterial content. This improves the overall quality of the product throughout the period of use with the end consumer. For example, the food gas used to protect the foods in the above container and / or plastic bag may be from AGA which produces this type of gas mixture. The gas mixture could be AGA biogon mix food gas, which is a mixture of 70% nitrogen, 20% carbon dioxide and 10% oxygen. Or 60% oxygen and 40% carbon dioxide, choice of gas mixture depends on what product is desired to be protected in the system.

Use Model Requirements

A repackaging system for use in private homes, which is newly characterized by the end-user of food purchased packaged in or without a protective atmosphere, can re-establish this protective gas species around the food after the food has been removed from the original packaging. This is done by placing the food in an oxygen-tight container and / or bag, which is then evacuated by means of a vacuum pump for oxygen from an emptying / filling station, and then adding food gas from the emptying / filling station to the container and / or plastic bag. Thereafter, the container and / or plastic bag can be removed from the emptying / filling station and placed in the refrigerator again until the next time the product is removed and the process can be repeated.

This inhibits the growth of microorganisms and significantly improves the shelf life, smell and appearance of food compared to storage in atmospheric air.
