Description

  The present invention relates to an antibacterial composition having effects such as disinfection, antibacterial, sterilization, and deodorization for the purpose of preventing corrosion of foods, long-term storage and ensuring safety.

Conventionally, “chlorine preparations” or “alcohol preparations” or “cationic surfactants” or “oxidation preparations” such as ozone are used as preparations for the preservation, sterilization, deodorization and freshness preservation of food materials. It has been known. However, these preparations are regarded as problems with respect to safety to living bodies, and are also questioned in terms of destroying the nutrients and tastes of food materials. Further, it is mainly used for sterilization, and almost no action such as deodorization and freshness maintenance can be expected. Furthermore, in known preparations, for example, “rough skin / respiratory illness / accumulation damage” is regarded as a problem as an influence on the living body of the user, and there is nothing safe yet.
For these purposes, various antibacterial substances obtained from plant-derived extracts have been used, but as related to the present invention, proanthocyanidins obtained from peanut thin skin are used as external preparations for skin. Utilization has been made (Patent Document 1).
Moreover, in order to make it easy to eat the food which utilized the antibacterial action of polyphenol, seawater, such as deep sea water, is desalted and mixed (patent document 2).

JP 2004-115466 A Japanese Patent No. 3561777

  Conventionally, disinfectants and antibacterial agents that can be used for fresh foods and do not harm the human body have not been realized, and thus food safety cannot be realized in a true sense. The present invention provides an antibacterial agent that does not use chemicals harmful to the human body, is safe for the human body, has excellent disinfection and antibacterial effects, and can store food for a long time without using harmful food additives and surfactants. An object of the present invention is to provide an antibacterial composition capable of ensuring food safety. This antibacterial composition prolongs the freshness of food, prevents waste due to corrosion, helps solve human food problems in the future, and contributes to improving the efficiency of economic activities.

The present invention repeats many experiments in order to achieve the above-mentioned problems, and the extract material extracted from the seed coat or seed of a nut-based plant that is a natural plant and seawater, in particular, the iceberg that gave birth to a life form in ancient times melts. It is confirmed that the disinfecting and sterilizing effects can be sustained continuously by increasing the ionic activity of acidic ionic water made from deep ocean water (ie, iceberg ocean water) with a titanium oxide photocatalyst. did.
That is, in the present invention, when desalting seawater such as “iceberg ocean water”, removing water, adjusting its components and increasing sulfate ions (SO ₄ ²⁻ ) to make it strongly acidic, antibacterial activity is achieved. It is known that it has sterilizing, deodorizing and freshness maintaining effects, but its effectiveness is limited, and it has been confirmed that the effect disappears when diluted. On the other hand, extracts extracted from seed coats or seeds of nut-based plants such as peanuts are known to have antioxidant, protein saccharification, anti-HIV, etc. as their physiological functions. Has not been confirmed.
In the present invention, these two raw materials are mixed in an appropriate ratio, and the photocatalytic effect of titanium oxide enhances ionization, so that even when diluted with purified water, its antibacterial, deodorant, and freshness retention capabilities are dramatically improved. It provides an antibacterial composition that is improved and maintains its effect.

That is, the present invention is a mixed solution comprising desalted seawater and an extract extracted from the seed coat or seed of a nut-based plant, and the mixed solution is a photocatalyst comprising titanium oxide (TiO ₂ ) irradiated with ultraviolet rays. It is an antibacterial composition which has been contact-treated.
The seawater is preferably “iceberg seawater”.
The extract extracted from the seed coat or seed of the nut-based plant is preferably the outer layer of the seed coat or seed of peanut.
Further, the seawater is desalted from seawater collected from the ocean, dried until the water content becomes 1/500 or less, and sulfate ions are added to obtain strongly acidic ionized water having a pH of about 0.3, which is about 100 It is preferable that it is diluted to 2 times.
Further, this antibacterial composition contains 86-99.2% by weight of the seawater and 0.7% by weight or more of an extract extracted from the seed coat or seed of a nut-based plant, and purified water as necessary. In addition, the total amount is preferably 100% by weight.
Even if any one of these antibacterial compositions is further used as a diluted solution diluted 100 to 10,000 times with purified water, the antibacterial and deodorant effects are maintained.

  The effect of the present invention is that the antibacterial agent has excellent antibacterial sterilization, deodorization and freshness maintaining effects, and even if mixed in food, the material is natural, so it is highly safe for the human body have. Further, even when compared with conventional disinfectants, the time for generating a bactericidal effect is early and the bactericidal effect lasts for a longer time.

The antibacterial composition of the present invention or a diluted solution thereof can be used as an antibacterial agent, disinfectant, freshness-preserving agent, water quality preservative and the like.
For example, a large amount of disinfectant and disinfectant is used on production machines, cooking utensils, cooking tables, cooks, cooking room floors, etc. in food production plants, but there are problems with food safety and safety. As an alternative disinfectant / disinfectant, there is a great advantage of using the antibacterial composition of the present invention. In food factories and the like, conventionally used germicidal detergents are ethyl alcohol, hypochlorous acid, cationic and biguanite germicidal detergents, and all of them except alcohol are feared to have adverse effects on the human body.
Recently, ready-made side dishes, rice, and bento foods, which are stored at room temperature suitable for bacterial growth, are called “meal” and their market has expanded rapidly. Cooked rice is sold immediately after cooking and the distribution temperature cannot be 18 degrees or less, so the shelf life is around 12 hours to 36 hours, but the disposal loss due to spoilage is large. In order to reduce the loss, sterilizing detergents and preservatives are used in raw vegetables, raw products, and kneaded products used as side dishes to extend the shelf life.
Many other processed foods also use food preservatives such as sorbic acid and benzoic acid. Food additives are a powerful source of active oxygen, so there is a concern that a large amount of intake will accelerate "aging" and certainly harm health. Dangerous ingredients such as fish paste products (Kamaboko, Chikuwa), meat products (ham, sausage, etc.), raw egg products (Tarako, Sujiko, etc.), pickles, soft drinks, snacks, etc. It is said to be food.

Since the antibacterial composition of the present invention has a great effect on the preservation of food freshness, disinfection and sterilization, it can replace the food additives conventionally used for these purposes and can be detoxified. Is very large and has already received inquiries from many food processors.
Since the safety to the human body is ensured, an appropriate sterilizing and disinfecting effect is achieved, and the shelf life of the food can be extended, the economic merit is also very large. Providing safe antibacterial, deodorant, and freshness-preserving agents that are harmless to the human body when the food safety and security are screamed and the alarm is sounded about the adverse effects of food additives on the human body. Social contribution is very big.
In addition, antibacterial and freshness-preserving agents that are easier to use and more effective than conventional products for maintaining freshness of raw vegetables and strawberries, keeping freshness of fish, keeping freshness of fish eggs, keeping freshness of meals, and keeping freshness of fresh flowers. Was invented to help solve the food and energy problems, and the benefits to society are enormous and its effects are enormous.

In the present invention, natural plants are specifically focused on peanuts (peanuts) dressed in polyphenols, and an extract extracted from the seed coat and the outer periphery of the seed is used as one of the raw materials.
Peanut seed extract, which is one of the raw materials, contains glycosides such as luteolin and rutin, and polyphenols (polyanthocyanidins and resveratrol). The content of heavy metals is 20 ppm or less. It is 0.12% or less.
Moreover, although the antioxidant function, protein saccharification reaction inhibitory action, and the anti-HIV action (patent 3010258) are confirmed as the physiological function, the antibacterial effect is not reported.
The peanut seed extract is, for example, as a “plant-derived extract” collected from the seed coat of peanut and the outer periphery of the seed from Shiba Hashi Chemifa Co., Ltd. (3-28, Tenmabashi, Kita-ku, Osaka, President Masayoshi Ohira) Available.

The other raw material is seawater, especially “iceberg seawater”. When polar glaciers melt, iceberg water has a high salinity and high salt density due to the difference in salt concentration, so it sinks to the sea floor of about 4,000 meters at a stretch (this is called the bloom phenomenon). It goes around the earth like a belt. Depending on the topographical conditions, there are places where this flow springs up to the upper part of the sea at some points, and the seawater collected there is “iceberg seawater”. The “iceberg ocean water” used in the examples described later was collected off the Pacific Ocean near Hachijojima and hose down to 300 m or less so that the spring water does not mix with other seawater. “Iceland Current” has little organic matter, has a mineral balance similar to that of the human body, and contains over 90 minerals.
Compared to iceberg ocean water, general seawater is mixed with various impurities and its components are different, so even if the same manufacturing method is used, the bactericidal effect and its stability are not sufficient. It is preferable to use it.

In the present invention, NaCl contained in about 4% of seawater, particularly this “iceberg seawater” is removed, chlorine ions (Cl ⁻ ) are reduced, moisture is reduced to 1/1000, It is preferable to use “strongly acidic ionized water” which is obtained by adding extracted sulfate ions so that the pH is about 0.3.
The “strongly acidic ionic water” created from the iceberg ocean water is, for example, a production method developed by Monsam Michel Co., Ltd. (a method of “salting” using a physical method (decompression, stirring) called the vortex tube method)) The product desalted with is sold under the trademark “Hasar”. The features of this product are listed below.
-It has a favorable effect on the living body due to organic mineral characteristics.
・ Sterilization, deodorization, freshness retention, chemical decomposition, etc.
・ Stable and does not change properties when touched by organic substances. ・ Non-toxic, non-toxic (drinkable) and safe for the human body.
Note: “Iceland Current” is a trademark of Mont Saint Michel.

Seawater as a material of the present invention needs to be subjected to concentration control at a pH value. For example, “strongly acidic ionic water” (hasal solution) controlled to pH 0.3 to pH 0.4 may be used. . This main component contains a large amount of sulfate ion and sodium, and in addition, a small amount of chloride ion, calcium, potassium, boron and the like. It is characterized in that sulfate ion is contained 50 times or more by weight with respect to chloride ion. This “strongly acidic ionic water” has strong sterilization, deodorization, and freshness retention effects in the stock solution, but when diluted simply with water, its effectiveness is weakened, the sterilization target is limited, and the effect cannot be sustained.
For example, in the culture experiment of the bactericidal effect on staphylococci of a solution obtained by diluting this “strongly acidic ionic water” (pH 0.3) 50 times, the initial bacterial count was 8.2 × 10 ⁵ but 2 Only an effect of a reduction to 0.0 × 10 ² was observed.
Further, when diluted 100 times, it decreases to 5 × 10 ³ , and when diluted 1000 times, it only decreases to 2.0 × 10 ⁵ , and the sterilizing effect is almost lost.

However, the antibacterial composition of the present invention has a strong antibacterial effect even when diluted by using the above two main raw materials, due to an appropriate blending ratio and the ion activation effect of the titanium oxide photocatalyst. be able to.
For example, with 2.5% by weight of peanut extract, acidic ionic water obtained by diluting the above “strongly acidic ionic water” (Hasal solution) 100 times is mixed in a 1% step from 82% to 99.5% by weight. Then, the bactericidal effect was measured, but the bactericidal effect was not observed when the acidic ionized water diluted 100 times was less than 86% by weight. On the other hand, when the peanut extract was sequentially reduced, the bactericidal effect disappeared when the peanut extract was reduced to 0.7% by weight or less.
In the present invention, this peanut extract and the above-mentioned “strongly acidic ionic water” (hasal solution) mixed and stirred at the above ratio are brought into contact with the titanium oxide photocatalyst irradiated with ultraviolet rays for several tens of seconds, A stock solution of antibacterial / deodorant (antibacterial composition of the present invention) was used.
FIG. 1 shows a diagram of an ion activation apparatus using a titanium oxide photocatalyst according to the present invention. As the titanium oxide photocatalyst, for example, a ceramic ball coated with titanium oxide (manufactured by Chie Environmental Division) can be used, and this titanium oxide photocatalyst is irradiated with an ultraviolet lamp.

  In the present invention, an antibacterial / deodorant that has a long-lasting effect even if it is diluted by the blending ratio capable of maximizing the efficacy and the activation effect of the titanium oxide photocatalyst using the above two main raw materials. It was realized. Until the discovery of the above findings, samples were made by adding various amounts of seawater, electrolyzed water, tap water, ozone water, etc. to the peanut extract and evaluated for bactericidal and deodorizing effects. Performance could not be demonstrated with the combination.

Example 1
In this example, “iceberg seawater” as a raw material was separated and extracted from NaCl and other major components, NaCl was removed, chlorine ions were reduced, water was reduced to 1/1000, and sulfuric acid previously extracted from seawater. “Hasal liquid” (manufactured by Monsa Michel Co., Ltd.), which is “strongly acidic ionic water” added with ions and adjusted to pH 0.3 to 0.4, was used.
Purified water was added to this “strongly acidic ionic water”, stirred well, and diluted 100 times. Nuts seeds and seed coat extract (Shibahashi Kemifa “plant-derived extract extract”) were mixed with 0.7 to 3% by weight of the diluted solution of the “strongly acidic ionic water” and further stirred. did. 1 is used as an ion energy intensifier shown in FIG. 1 (a titanium catalyst is a titanium oxide ceramic ball (5 mm) manufactured by Chie Co., Ltd.), and a high-power low-pressure ultraviolet lamp (Harrison) The device was irradiated by Toshiba Lighting Co., Ltd.)) to obtain a stock solution of antibacterial agent (antibacterial composition). The pH of this stock solution was 2.1-2.3.
The manufacturing process of the antibacterial composition of the present invention is shown in FIG.
This stock solution was diluted 100-fold to 10,000-fold with purified water obtained by purifying tap water, and used separately for each purpose.

Example 2
In order to confirm the photocatalytic effect of the antibacterial composition of the present invention, the following experiment was conducted.
Compare the bactericidal and antibacterial effects of the bactericidal agent prepared in Example 1 (liquid obtained by diluting the stock solution 500 times) and other liquids that do not come into contact with the photocatalyst in the same manner as in Example 1. did.
First, Escherichia coli and Staphylococcus aureus strains were precultured at 37 ° C. for 24 hours, and diluted to a predetermined concentration with physiological saline. Two ml of the sample antibacterial agent were prepared for each sample, 1 ml of the test bacterial solution was added thereto, and the number of viable bacteria after culturing for 24 hours in a culture environment was measured. The results are shown in Table 1.
When the antibacterial composition of the present invention was used, the bacteria were greatly reduced, and it was proved that the antibacterial effect was great. The effect of bringing it into contact with titanium oxide (photocatalyst) activated with ultraviolet rays enhanced its sterilizing power, and a sterilizing effect of more than an order of magnitude was recognized for those not adding the photocatalytic effect.

Example 3
Table 2 shows the results of measuring the bactericidal disinfection effect on four types of bacteria collected from the kitchen using the bactericidal agent prepared in Example 1 (liquid obtained by diluting the stock solution 500 times). Most of the bacteria were killed in about 5 minutes, and the generation of bacteria was not confirmed after 10 minutes or more.

Example 4
The bactericidal agent produced in Example 1 (liquid obtained by diluting the stock solution 1000 times) was used for washing fresh strawberries, and the freshness retention effect of the strawberries was examined. As a result, the result of remarkable freshness retention was obtained as compared with ordinary water washing.
The freshness maintenance test was conducted as follows. Fresh strawberries washed with tap water and those washed with this disinfectant for 2 minutes are drained into a tapper container and stored in the refrigerator so that they do not dry. Changes until 5 days later were observed.
As shown in FIG. 3, the surface washed with tap water was discolored partly from the third day after the start of the test, started to rot on the fourth day, and mold was generated on the fifth day. I felt a bad smell. What was washed with the disinfectant of the present invention had almost no change in appearance even after 5 days.

Example 5
The freshness maintaining effect on fresh flowers of the fungicide prepared in Example 1 (a solution obtained by diluting the stock solution 5000 times) was examined.
The quality preservation effect of fresh flowers was examined as follows. Flowers were put in each vase containing the tap water and the diluted fungicide of the present invention, and the changes over time were compared and observed.
(1) Comparison of cut rose flowers in a vase in summer: In the case of tap water, the flowers wilted on the third day, the water color changed, and after 5 days, there was a corrosive odor. The flowers in the vase containing the fungicide of the present invention were normal even on the 5th day, and the water did not generate algae (discoloration) even after 20 days, did not corrode, and the color did not change.
(2) Comparison of winter chrysanthemum and lily cut flowers in a vase: In the case of tap water, the chrysanthemum flower drooped on the fifth day. The leaves have also withered. Even after 10 days, the flowers in the vase containing the fungicide of the present invention maintained a flower shape almost unchanged from the original.

Example 6
A conventional preservative food added to the product prepared by mixing the bactericidal agent produced in Example 1 (diluted stock solution 500 times) with the appropriate amount (5 to 10%) of water used to make cream puff and cream. I compared it with the one made by putting things. As a result, the freshness retention effect was greater than that obtained by adding a preservative (benzoic acid or the like) recognized as a conventional food additive. Furthermore, since the freshness-keeping agent of the present invention is odorless and tasteless, the taste is improved without impairing the original taste of cream puffs and fresh creams.
