Description

Antioxidant with antibacterial function and its manufacturing method {DEOXIDIZING AGENT WITH ANTIBIOSIS AND METHOD FOR PREPARATION THEREOF}

The present invention relates to an oxygen scavenger having an antibacterial function and a method of manufacturing the same, and more particularly, to an oxygen scavenger having an excellent antibacterial function without the deoxygenation function of the iron powder deoxygenation agent and the ease of the oxygen scavenger. It relates to one manufacturing method.

Due to changes in dietary patterns and the development of the food industry, processed foods are widely distributed in general. For this purpose, it is important to preserve foods without altering them for a long time. It is common to distribute and store the product by packing it in an airtight container such as a material such as this. In order to prevent oxidation of the packaged food and to suppress the survival or proliferation of microorganisms, oxygen must be strictly excluded from the packaged container. .

In addition, in order to prevent the deterioration and decay of food in the packaging, it is required to completely block the bacterial microorganisms causing such decay, and for this purpose, antimicrobial agents such as preservatives are used in a conventional manner.

The role of the conventional oxygen scavenger is packaged together with the food in the sealed packaging to remove oxygen in the packaging space within a certain time to maintain the oxygen free state in the packaging, thereby inhibiting the growth of aerobic bacteria and prolong the shelf life of the food. At the same time it works to improve the freshness of food.

Representative of such an oxygen scavenger is an oxidation reaction of iron powder, in which an oxygen scavenger made of an iron-based composition in which metal chlorides are added as an accelerator is sealed together with food in a sealed packaging container and iron in the presence of moisture in the container. It is the most commonly used to preserve the quality and freshness of products such as foods by causing oxygen to react and remove oxygen.

Oxygen deoxidant using iron, for example, the Republic of Korea Patent Application No. 1988-0005890 is named "high-durability deoxidant", "iron, water, halide metallization, a poorly water-soluble filler in the conventional one, reaction High-persistent deoxygenating agent characterized by adding potassium permanganate or potassium dichromate as an accelerator. "Korean Patent Application No. 1999-0060072 is entitled" Food preservative deoxidant "," iron (Fe) Alkali metal chlorides, rust preventing and carbonates having a circulating reaction function are combined as chemical reaction equivalents, and 5-20wt% of additives are added to the reaction system to uniformly supply water to the total amount of the reactants. And a deoxidant, characterized in that the Korean Patent Application No. 2004-0063598 discloses a "deoxidant composition, deoxidant package and oxygen Under the name of "water method", "an oxygen scavenger composition comprising 100 parts by weight of iron powder and 0.1 parts by weight or more of a promoter comprising an alkali metal salt or an alkaline earth metal salt having low moisture transport properties" Is starting.

In addition, it has been proposed as a food preservative to compensate for the shortcomings in the deoxidizer using iron of the above inventions, for example, the Republic of Korea Patent Application No. 1998-0010797 is named "food preservative and its manufacturing method", "In a food preservation deoxidant which is sealed like a food in a food packaging container after being filled in a breathable packaging agent, said deoxidizer; and 60 wt% (%) of porous zeolite mixed with ethyl alcohol and brine (HCl) After preparing a granule obtained by adsorbing an aqueous solution of 40% by weight (80%), 80% by weight of the granule (20%) and 20% by weight of polyvinyl alcohol (PVA P-17) were mixed and polyvinyl chloride was added to the surface of the granule. A alcohol granule which allows alcohol to be adsorbed to a predetermined thickness; a deoxidizing agent and an alcohol granule are filled in the air permeable packaging agent at a ratio of 5: 5, and then sealed in a food packaging container to seal the chemical reaction of the oxygen removing agent. (Oxidation) In addition, the alcohol granules from the alcohol granules to increase the preservation of food, the food preservatives have been disclosed as a vapor, and Korean Patent Application No. 1998-0703096 is named "preservation method and freshness preservation of food" "In connecting the vapor of isothiocyanic acid ester to food, the fragrance of the fragrance component is mixed in the vapor of this isothiocyanic acid ester, so that the odor of this isothiocyanic acid ester cannot be actually felt. To a method for preserving the freshness of food, characterized in that the invention.

However, the inventions related to the oxygen scavenger using the iron powder remove oxygen in the packaging using only iron oxidation, so that the expression of aerobic bacteria can be prevented, but the expression of anaerobic bacteria cannot be prevented. There is inconvenience to use antibacterial agent, food preservatives that do not use the deoxygenation action of the iron powder has no deoxygenation action has a limit in preserving the fresh food, only containing isothiocyanate ester It is just to use a bactericidal gas.

Accordingly, an object of the present invention is to not only completely remove oxygen in the food packaging container, but also to provide antibacterial function so that sterilization or suppression of anaerobic bacteria can lead to a new concept that can dramatically increase freshness and shelf life. It is to provide an anti-oxidant with antibacterial function.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail by preferable embodiment.

As described above, the oxygen scavenger having an antibacterial function is an AIT carrier impregnated with an allyl isothiocyanate (AIT), which is an irritating volatile substance as a main component of wasabi or mustard, in a proportion of water. It contains at a certain ratio.

In addition, according to the present invention, the AIT carrier is mixed at a ratio of 20 to 100% by weight based on the weight of the oxygen scavenger. In addition, since the antibacterial effect is sufficiently exhibited at 100% by weight, it is not desirable to increase the antimicrobial effect even if it is added more than that and increase the manufacturing cost.

The oxygen scavenger using iron powder which is generally used is obtained by homogeneously mixing iron powder with a hydrous carrier such as diatomaceous earth and various accelerators for promoting oxidation of iron powder as described above, wherein the moisture content is 18 to 24%. Shall be.

By the way, the deoxygenating agent having an antimicrobial function of the present invention separately prepared and matured the AIT carrier using AIT as described in detail below to the conventional deoxygenating agent to give flowability, mixed in a constant ratio and iron powder and It is a way of producing products using existing facilities.

As described above, allyl isothiocyanate used in accordance with the present invention, that is, AIT, is a main ingredient of wasabi or mustard. The antimicrobial activity of this AIT has been shown by many papers and application examples that it is inhibitory to various bacteria, but it is not easy to handle due to the strong odor and volatility.

In particular, when the above-mentioned AIT is used with a conventionally known deoxidizer such as an iron powder deoxidizer, the initial deoxygenation capacity of the deoxidizer is remarkably reduced, so that the deoxygenation effect is extremely low, thereby suppressing the growth of aerobic microorganisms. Not only is it practically insignificant, but also the method of simply adding AIT to iron powder deoxidizer causes problems in the flow of raw materials due to the addition of organic volatiles. It was difficult and could not be put to practical use.

Therefore, the present invention provides an AIT carrier prepared as in the following preferred embodiment, thus enabling the initial deoxygenation capacity to be maintained as well as having little effect on the ability of the existing deoxidizer described above. It is possible to provide an oxygen scavenger with antibacterial function that can be easily produced without a production facility.

The process for preparing the AIT carrier according to the present invention is as follows:

First, the mixture is diluted by 60% by weight of AIT and 40% by weight of alcohol to form a mixture. Here the alcohol acts to quickly impregnate the AIT into the carrier and slightly volatilizes. The spirit is not particularly limited thereto, but preferably 95% ethanol is used.

Next, the mixture is homogeneously mixed with the carrier at a weight ratio of about 2: 8 to 1: 9 so that the mixture is completely impregnated with the carrier. The type of carrier that can be used according to the present invention may be selected from diatomaceous earth, activated carbon, silica, alumina, zeolite, bentonite, calcite, activated clay, talc and the like, and if it can contain enough moisture to help the oxidation of iron. If it is, other than that is possible. In particular, diatomaceous earth is preferred in view of moisture content and fluidity.

The AIT mixture obtained in the above step is added to the carrier impregnated with a certain amount of water so that the water is completely impregnated to obtain an antibacterial and deoxygenating agent according to the present invention having a constant water content. Here, preferably, the AIT carrier is impregnated with 82% by weight of the carrier impregnated with 18% by weight of water so that the water is completely impregnated to prepare a water content 18% AIT carrier.

As described above, the composition ratio of each component of the AIT carrier prepared according to the method of the present invention is most preferably 62 to 78% by weight, 12 to 28% by weight, 6 to 8% by weight of AIT, and 1.5 to alcohol. 2.2 weight percent.

Hereinafter, the present invention will be described in more detail with reference to Examples and Experimental Examples, but the scope of the present invention is not limited thereto.

Example 1

600 g of allyl isothiocyanate (AIT) was mixed and diluted with 400 g of 95% ethanol to obtain about 1 kg of mixture.

The obtained mixture was mixed homogeneously with 5.5 kg of diatomaceous earth so that the AIT mixture was completely impregnated with the diatomaceous earth. 1430 ml of water was added to the diatomaceous earth impregnated with the AIT liquid mixture thus obtained to completely impregnate water, thereby preparing an AIT carrier having a water content of about 18%.

The AIT carrier and the iron powder deoxidizer were mixed in the same weight ratio to prepare an antioxidant having an antibacterial function according to the present invention.

Example 2

An oxygen scavenger having an antibacterial function was prepared in the same manner as in Example 1 except that the AIT carrier and the iron powder deoxygenator were mixed at a ratio of 1: 2.

Experimental Example 1

Oxygen and Carbon Dioxide Inhibitory Test of Antioxidant with Antibacterial Function According to the Present Invention

The freshness of foods can be determined by measuring the increase of oxygen and carbon dioxide in the package over time. In particular, food corruption generally indicates that the respiration of microorganisms increases, leading to an increase in carbon dioxide. Therefore, in the present experimental example, the increase in the amount of oxygen and carbon dioxide in the fish cake packaging was measured over time and the results are shown in Table 1 below.

As a detailed experimental method, a commercially available commercially available deoxidizing agent having an antibacterial function according to the present invention obtained by Examples 1 and 2 and a commercially available iron powder deoxygenating agent which are not commercially available. After packing the fish paste and storing at room temperature, the generation of oxygen and carbon dioxide in the wrapping paper over time was measured. The commercially available fish paste was purchased using about 250 g of fish paste (within shelf life) to which a conventional oxygen absorber was added and used after removing all oxygen scavenger. 500cc each of commercially available deoxidizer and the antibacterial deoxidant obtained according to the example was introduced into a package with fish cake, and then the inside of the package was degassed and then 300cc of air was completely sealed. After storage at room temperature, after 1 day, 5 days, 7 days, 10 days, 15 days, the amount of oxygen and carbon dioxide remaining in the fish cake packaging was measured.

As can be seen from the above results, in the case of the control group, carbon dioxide generation was rapidly increased before and after 5 days of storage, and the decay by microorganisms started. In the case of commercial deoxidants, carbon dioxide was generated about 5 days, which is the initial stage. Although less, it can be seen that the increase significantly before and after 10 days. In contrast, in the case of Examples 1 and 2 according to the present invention, the generation of carbon dioxide was extremely insignificant even after 15 days, and it was confirmed that the breeding of microorganisms did not start until this time. . In addition, since the experimental conditions of the present experimental example was carried out at room temperature, it will be indirectly understood that the freshness can be further extended to 15 days or more during refrigeration distribution.

In addition, the antibacterial deoxygenation agent of the embodiment according to the present invention removes all the oxygen in the oxygen wrapping paper after one day, and exhibits the same deoxygenation capacity as that of the commercially available deoxidizer with excellent deoxygenation ability (product of T Company). It can be seen that the persistence of the deoxygenation capacity is superior to that of existing commercial products.

Experimental Example 2

With antibacterial function according to the present invention Deoxidant  Test of Microbe Control

In the present experimental example, the microbial control experiment of the fish paste using the deoxidant with antibacterial function according to the present invention was carried out.

As a detailed experimental method, about 250 g of fish paste in the expiration date of the conventional oxygen absorber was purchased, and after removing all the oxygen absorbents, the control group without adding any oxygen absorber and the AIT amount were 0.1 and 0.2 ml according to Example 1 The obtained antimicrobial deoxidant was introduced into a wrapper together with the fish paste, and then the inside of the wrapper was degassed and then 300cc of air was completely sealed. After storing the packaged fish paste at room temperature, the number of bacteria in the fish paste package was measured after 1 day, 5 days, 10 days, 15 days, and 20 days, and the results are shown in Table 2 below.
