Abstract

PURPOSE:To obtain a carbon dioxide preparation capable of preventing decomposition of food, occurrence of mold and change in qualities, harmless to the human body, by blending an edible alkali substance containing carbonic acid with an acid. CONSTITUTION:An alkali substance containing an edible carbonic acid such as sodium hydrogencarbonate, ammonium hydrogencarbonate, etc., is blended with an edible acid such as acetic acid, citric acid, etc. to give fine powder or an aqueous solution. The aqueous solution is adjusted preferably to 6.5-9.5pH and optionally the bland or the aqueous solution is blended with 0-4wt.% salt based on 1 volume aqueous solution.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a food preservation formulation used to prevent food spoilage, mold growth, and deterioration.

(Conventional technology) Conventional food preservation methods include drying, dehydration, refrigeration, freezing,
Sterilization, sterilization, salting, candiing, pickling, gas storage, smoking,
Methods using preservatives, etc. are being used.

(Problems to be solved by the present invention) For example, when storing food by freezing, freezing equipment is required, which is expensive and difficult to handle at low temperatures, and spoilage tends to progress more easily after thawing. There are problems such as:

There is also a chemical preservation method that uses carbon dioxide (gas) to treat the fruit, but it is difficult to maintain freshness for a long time.

There is also a method of preserving sodium erythorbate using a solution, but adding it to foods is subject to many regulations under the Food Regulation Act, so it cannot be added to all foods.

As mentioned above, conventional food preservation methods have not been satisfactory in terms of high costs due to equipment or work, storage stability, and taste safety.

The present invention provides a food preservation formulation that overcomes these drawbacks.

(Another Means to Solve the Problems) The present invention is a carbon dioxide preparation characterized by being a mixture of an edible carbonic acid-containing alkali and an acid. The aqueous solution of the mixture of alkali and acid is a carbon dioxide preparation having a pH of 6.5 to 9.5.

Further, it is a carbon dioxide preparation in which 0 to 4% of common salt is added to 1 volume of the aqueous solution of the alkali and acid mixture or the mixture.

(Function) When the carbon dioxide preparation of this invention is a mixture, it can be directly added to food or mixed or sprinkled as a fine powder, and when it is an aqueous solution, it can be sprayed or immersed in the solution. As a result, the food retains its fresh color and freshness for a long period of time.

When the aqueous solution of the mixture has a pH of 6.5 to 9.5, it exhibits a remarkable bactericidal effect.

Alkalies, acids, and salts act on food products either singly or in a synergistic manner to maintain bright color and freshness.

It goes without saying that foods sprayed with or mixed with the formulation of this invention for food preservation will not be harmful to the human body.
The taste of the food remains the same.

(Example) This invention will be explained with reference to the following examples.

Acetic acid, an edible organic acid, per 1 volume of water: 0.01
A saturated aqueous solution of ammonium hydrogen carbonate or sodium hydrogen carbonate, which is an alkaline substance and contains carbonic acid, is mixed into the aqueous solution of ~10 ml at a ratio of 1:1 to 3:1. The preparation thus obtained has a pH of approximately 7.0 to 10.0 and has extremely strong antibacterial activity.

Citric acid, an organic acid, is used as the edible acid.
When 1.0-15% of salt is mixed with 1 volume of water,
This formulation is extremely effective for high protein foods.

The aqueous solution of the formulation of the present invention, excluding salt, can be sprayed at an appropriate concentration depending on the type of vegetable, fruit, etc., thereby maintaining its freshness for a long period of time.

In addition, a mixture of an edible carbonic acid-containing alkaline substance and an acid can be added directly to the processed food product during the processing process, and the finished food product can also withstand long-term storage.

Tables 1 to 5 list the results of preservation tests on the following various foods using different formulations of the carbon dioxide preparation of this invention.

In each table, the prescription for B20A solution is a mixture of 4.5-5.0% sodium bicarbonate, 0.05-0.07% acetic acid, and 25-3.0% salt per 1 volume of water. .

The formulation of the B2O liquid is a mixture of 1.2 to 1.51% of ammonia hydrogen carbonate A and 0.05 to 2% of acetic acid (LO2%) per volume of water.

The prescription for Y2O liquid is 4 parts sodium bicarbonate per 1 volume of water.
．． 0 to 4.5% and citric acid 0.5 to 0.7% are mixed into nine liquids.

(Effects of the Invention) As described above, the carbon dioxide preparation according to the present invention can be used simply by spraying it on all kinds of foods such as fresh foods, processed foods, vegetables, and fruits, or by simply adding it to the food during the food manufacturing process. It maintains its color and freshness for a long period of time, and has no change in taste, making it an extremely effective preservative.

The chemicals used are special chemicals, do not require processing equipment, are low in cost, and are safe food preservation preparations.
