One of the causes of the deterioration of the taste of food and drink is the oxidation of the food and drink by oxygen. For example, this occurs due to oxygen present in a minute amount in the container at the time of manufacture without opening the container such as a bottle of beverage such as wine, liquor, coffee and tea. Oxidation, unlike rot, is not bad for the body, but it will reduce the flavor of the beverage. In order to prevent oxidation of the beverage product, when the beverage product is packed in a container such as a bottle, the beverage product is shipped by replacing the air in the container with nitrogen gas.

In addition, foods such as retort foods and canned foods, or foods such as tea leaves, when put in a package or can, in order to prevent oxidation of these beverages, similar to the beverages,
In the food product manufacturing factory, the food product is shipped by replacing the air in the package or can with nitrogen gas.

However, once a consumer purchases the food and drink, and once the container or package is opened, the food or drink starts to oxidize. When these are left over or left over and eaten and eaten at a later date, there is a problem in that the food and drink are more oxidized and the flavor and freshness thereof are lowered.

After the consumer purchases the food and drink, the prior patent literature that prevents oxidation of the food and drink that the flavor and freshness of the food and drink are reduced. None of them were disclosed, and those disclosed in the following Patent Documents 1 and 2 are merely known.

JP 2006-264781 A JP 2007-41 A

The device disclosed in Patent Document 1 is a wine antioxidant device, and a thin string is attached to the top of an oxygen scavenger provided with a spacer so as not to touch the inside of a bottle of wine left over. When inserted and sealed, the string is sandwiched between the bottle and the stopper, so that the oxygen scavenger is fixed in place in the bottle, and the oxygen scavenger absorbs oxygen in the bottle and removes oxygen in the bottle. This prevents the oxidation of wine. However, the one disclosed in Patent Document 1 has a problem that it takes time and labor to set the oxygen scavenger in the bottle. Moreover, what was disclosed by the said patent document 1 can only be used for the oxidation prevention of wine, cannot be used for the oxidation prevention of other food-drinks, and is not versatile. There was a problem.

Moreover, what was disclosed by the said patent document 2 is related with the freshness maintenance method and its apparatus which can keep freshness of fresh food, a fresh flower, etc. favorable, The air or nitrogen gas is contained in the storage atmosphere of fresh goods. The nitrogen compound produced | generated by the electrostatic discharge process was made to exist, and since the apparatus for producing | generating a nitrogen compound was required, there existed a subject that cost was high. Moreover, what is disclosed in Patent Document 2 can be applied to refrigerators and storages, and can also be applied to refrigerators and storages installed in ships, vehicles, etc. Although it can be used for a fruit orchard, there is a problem that it cannot be used easily in general households and food and beverage stores and is not versatile.

The present invention has been made in order to solve the above-mentioned problems, and is intended for use in beverages such as wine, liquor, coffee, and tea, or food such as retort food, canned food, and tea leaves. When a consumer such as a person purchases, opens a container or a package, and then drinks or eats these foods and drinks, and later eats and drinks them, oxidation of the food and drink progresses. In order to prevent this, the nitrogen gas filled in the aerosol can is injected into the container containing the food and drink, and the air in the container is replaced with nitrogen gas by covering the container, thereby oxidizing the food and drink. An object of the present invention is to provide an aerosol filled with nitrogen gas for preventing and freshening foods and beverages so as to prevent and maintain freshness.

This invention solved the said subject by employ | adopting the means of filling the nitrogen gas which serves as a propellant and antioxidant in the aerosol can which is not equipped with the dip tube.

The aerosol filled with anti-oxidation nitrogen gas of the present invention food and drink is used for drinks such as wine, liquor, coffee and tea, or food such as retort food, canned food, tea leaves, etc. Prevent consumers from oxidising the food product when the consumer purchases it, opens the container or package, and then drinks or eats these foods and drinks later. Therefore, by spraying the nitrogen gas filled in the aerosol can into the container containing the food and drink, and replacing the air in the container with nitrogen gas, the oxidation and freshness of the food and drink are improved. Holding can be achieved. Nitrogen gas is a tasteless, odorless and colorless gas that is harmless to the human body and does not affect the taste of the food or drink even if it is injected into the food or drink. Furthermore, the aerosol filled with the antioxidant nitrogen gas of the present invention is lightweight and can be easily used by anyone, and its usable range is also used for food as well as beverages.

In general, an aerosol is one in which the contents are released in the form of a mist or foam outside the aerosol can through a valve by vaporization of a liquefied gas or the pressure of a compressed gas. When the button is pushed and the valve is opened, the mixed contents of the stock solution and the propellant are discharged from the button nozzle through the dip tube. The discharged contents become fine mists and bubbles due to the rapid expansion of the propellant. Nitrogen gas or oxygen gas is used as the compressed gas serving as the propellant.

The present invention is formed by filling an aerosol can 2 with nitrogen gas 1 used as a propellant for the aerosol. In the present invention, the aerosol can 2 is filled with nitrogen gas 1 serving both as a propellant and an antioxidant, without filling a stock solution of a cleaning agent for nasal washing with the propellant, as in an ordinary aerosol, for example. Therefore, the dip tube in the conventional aerosol can is unnecessary. In the figure, 3 is a valve, 4 is a button, and 5 is a nozzle.

The pressure of the nitrogen gas 1 filled in the aerosol can 2 is not particularly limited, but is preferably recommended to be in the range of 0.65 to 0.95 Mpa, particularly preferably 0.7 to It is recommended to be within the range of 0.8 Mpa.
