Abstract

PURPOSE:An antiseptic for food having porosity and high solubility, having inhibitory action on growth of Escherichia coli, comprising coral sand. CONSTITUTION:Coral sand obtainded from raw skeleton of coral reef or YOSEKIGUN is washed, heated to 80-150 deg.C, sterilized, dried, freeze-dried in an inert gas atmosphere at -180--200 deg.C and ground, to give an antiseptic for foods.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a food preservative using coral sand.

(Conventional technology and its problems) Consumer demands have changed with the development of the food industry, and now food products with a wide variety of uses are being manufactured.

For this reason, the types and amounts of food additives used are increasing year by year in order to improve quality, mass produce, ensure preservability, etc.

On the other hand, Chikuguchi (cyclamate, Cyre 1z

As food manufacturers have found themselves in an extremely difficult position, food manufacturers have found themselves in an extremely difficult position as food additives have become a major social problem and consumers are becoming more and more emotionally averse to food additives. has been done.

However, food additives are indispensable for enhancing the commercial quality, hygiene, or characteristics of the food itself.

In particular, preservatives that prevent food from spoiling due to microorganisms are important as they protect the health of consumers.

However, commonly used preservatives are relatively toxic, and it is undesirable to ingest various preservatives from various foods. The maximum amount is determined by the Food Sanitation Act, etc.

Conventionally used preservatives include benzoic acid, sorbic acid, and diphenyl.

However, although these preservatives improve the preservability of foods, they are highly toxic and may affect the human body.

Therefore, the current situation is that foods that do not contain preservatives are becoming popular these days.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a natural food preservative that is different from the conventional preservatives and is safe and does not harm human health but rather promotes health.

(Means for Solving the Problems) In order to achieve the above object, the gist of the present invention is to use coral sand as a preservative for foods.

That is, as a result of various research and consideration, the inventors have discovered that coral sand obtained from the living skeletons of reef-building corals and ramstones has an antibacterial effect and can be used as a preservative in place of conventional chemical compound preservatives. It turns out that it can be done. In order to prove this effect, we asked Chiba Prefectural Health Junior College 1 to conduct a test, and the results were as follows.

First, when Coral Sand, which is the object of the present invention, was partially sprinkled on a plate containing E. coli, the effect of inhibiting the growth of E. coli was observed only in the area where Coral Sand was sprinkled.

Next, when coral sand was sprinkled over the entire surface, the effect of inhibiting E. coli growth was clearly visible over the entire surface.

As a result of these experiments, it was found that coral sand, which had never been considered as a preservative, clearly has an effect of inhibiting the growth of E. coli, and it was found that it can be used as a natural preservative.

Although it is possible to further enhance the preservative effect by attaching - to coral sand, the coral sand of the present invention can fully exhibit its effect as a preservative even without attaching silver.

Coral sand as referred to in the present invention is coral sand obtained from living skeletons of reef-building corals and sheep fossil groups, and as shown in Table 1, calcium carbonate (about 95% CaCO) is the main component and is an important biological component. It contains essential vitamin elements such as magnesium, strontium, sodium, potassium, phosphorus, and chlorine, as well as trace amounts of iron, copper, zinc, manganese, cobalt, and chromium.

These elements are accumulated and weathered by the life activities of reef-building corals, which are coelenterates.

Therefore, unlike other food preservatives obtained through chemical processing, it has an ecological chemical structure, is safe for the human body, and has mineral effects as its main component is calcium carbonate. The fact that it does not cause any harm to the human body is shown in the attached test and inspection report from the Tokyo Food Sanitation Association.

The method for producing the preservative of the present invention will be explained below.

First, naturally obtained coral sand is washed to remove salt, then heat sterilized and dried at 80 to 150 degrees Celsius, and then heated at room temperature for 15 minutes.
It is ground into 0 to 500 meshes, but the grinding can also be carried out by freeze-drying at -180 to -200°C in a nitrogen atmosphere.
It is also possible to mix it with seawater or spring water.

The finely powdered coral sand thus obtained is extremely porous and highly soluble, making it ideal as a food preservative.

(Effects of the Invention) As described above, the food preservative of the present invention is natural coral sand, and there is no risk of harm to the human body.Moreover, since the main component of coral sand is calcium carbonate, it is suitable for use as a food preservative. By using it as a food preservative, it not only has an effect as a preservative, but also contributes to health promotion by naturally replenishing calcium.
