もあり充分満足するほどには至っていないのが現状であ
る。Conventionally, various methods such as frozen storage methods and chemical addition methods have been used for long-term preservation and freshness maintenance of fresh foods, especially fresh fish, meat, vegetables, etc., and although each method is effective, they also have drawbacks and are not fully satisfactory. The current situation is that this has not yet been achieved.

は食品経済の上からも種々難点があった。For example, in the case of frozen storage, there are problems such as requiring handling operations and equipment at very low temperatures, and that spoilage is more likely to progress after thawing. Furthermore, in recent years, preservation methods that involve adding chemicals have been increasingly prohibited or restricted due to health problems caused by the use of various synthetic preservatives. Therefore, even food that has been produced with great effort or made into mackerel size loses its freshness within a short period of time, making it unusable and having to be discarded, or eating rotten food and causing poisoning symptoms, resulting in food hygiene or food economic problems. There were various difficulties from the top as well.

ことが本発明の目的である。In this way, these foods can be processed without the need for laborious work in low humidity conditions, without the use of expensive equipment or chemicals that pose health risks.
A food freshness preserving agent that can be preserved or kept fresh for a long time and at least delay the progress of spoilage for a certain period of time, allowing producers to adjust shipments and respond immediately to demand; and a food freshness preserving agent using this preserving agent. It is an object of the present invention to provide a method and apparatus for maintaining.

Mix with. Salt is 1-1.5%
In particular, an aqueous solution having a concentration of 1.15% is preferable. When preparing an aqueous solution, it is preferable to use potable groundwater. The mixture is 1 volume of saline solution and 1 volume of saturated ammonium bicarbonate solution.
.. The volume is preferably 5 to 2.5 volumes, and the most preferred composition is 1 volume of 1.15% saline to 2 volumes of saturated ammonium bicarbonate. At this time, 111 degrees is ammonium bicarbonate 9.66%, salt 0.38%, specific gravity 1.0

きる。In the present invention, such a mixed solution of ammonium bicarbonate and common salt is heated, and the resulting vapor is sprayed onto foods, and is usually sprayed together with carbon dioxide gas. At this time, it is preferable to send and spray the vapor of the mixed liquid together with carbon dioxide gas under pressure, and separately to spray only carbon dioxide gas at the same time, but the method is not limited to this embodiment. Even by spraying only the mixed liquid, a considerable freshness maintenance effect can be achieved.
噴霧は数秒から約1分間程度行なう。Spraying is carried out for about a few seconds to about 1 minute.

。尚この試剤を用いても人体に有害な点はみられない。In order to see the freshness maintenance effect of the above mixed liquid and carbon dioxide gas, the above test examples are also shown below showing the results of tests by spraying the above mixed liquid and carbon dioxide gas on culture media in test tubes in which bacteria were cultured and on various commercially available meat slices. The mixed solution should have a bacteriostatic effect (not a bactericidal effect) to inhibit bacterial growth, and after spraying, wrap it in polyvinylidene chloride film, etc. and seal it.
It is clear that the effect can be maintained for 5 to 7 days if kept at ℃. When this liquid is sprayed onto food, the surface of the medium is maintained at an alkalinity of 8.6 to 9.0, which inhibits bacterial growth, and the carbon dioxide gas evenly spreads over the surface of the medium and food. A thin film or coating is formed to suppress contact with oxygen in the air and prevent oxidation. Although ammonium bicarbonate alone can exhibit a bacteriostatic effect, adding common salt can enhance this effect and maintain a fresh color tone even after storage. It should be noted that no harm to the human body is observed when using this reagent.

る。Thus, if the freshness maintaining agent of the present invention is sprayed on food, preferably together with carbon dioxide gas, the growth of bacteria is inhibited for 5 to 7 days by sealing the food and maintaining the food at a low temperature of 0 to 4°C. It is possible to maintain freshness and delay spoilage, which in turn allows producers to adjust shipments, eliminate work at extremely low temperatures, and eliminate waste such as discarding produced products. , also valid for consumer and distributor names.

を静かに採取して重炭酸アンモニウム飽和液を得る。(Test Example) (1) 4 kg of ammonium bicarbonate crystal powder was mixed with water (
(drinking groundwater) and mix with 5g and slowly heat the
Keep supersaturated at 7°C. The specific gravity of the liquid at this time is 1.091
It is. Cool this naturally until it reaches 13℃.
to precipitate needle-shaped crystals, and the supernatant liquid (specific gravity 1.085)
is gently collected to obtain a saturated ammonium bicarbonate solution.
一方結晶粉末食塩23gを2081.5gの水(飲料用
地下水)に混合溶解し、約1.15%の濃度、約1.0
50の比重の食塩水をつくる。On the other hand, 23g of crystal powdered salt was mixed and dissolved in 2081.5g of water (drinking underground water) to give a concentration of about 1.15%, about 1.0
Make a saline solution with a specific gravity of 50.
