Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food product containing a cyclodextrin inclusion compound of allyl isothiocyanate (hereinafter referred to as AIT). More specifically, the present invention is intended for the prevention of mold and sterilization of food during distribution and storage,
The present invention relates to a food containing a cyclodextrin clathrate of AIT. The food containing the cyclodextrin clathrate of AIT is provided with excellent antifungal properties and can be stored for a long period of time.

2. Description of the Related Art Food contains a large amount of water, sugars, proteins, etc., which are nutrient sources for microorganisms, so that microorganisms easily propagate, and therefore various preservatives are used. Has been done. Conventionally, as a preservative for direct inclusion in foods, for the purpose of preventing mold and sterilization of foods, benzoic acid, sodium benzoate, orthophenylphenol, and its sodium acid, sorbic acid, potassium sorbate, dehydroacetic acid, dehydro Synthetic preservatives such as sodium acetate, paraoxybenzoates and propionates (sodium salt, potassium salt) are the mainstream. However, such synthetic preservatives are concerned about the influence on the human body, and the use of the synthetic preservatives is now strictly regulated in terms of food safety. On the other hand, AIT, which is a component of wasabi, is known to have excellent bactericidal, antibacterial and antifungal effects, and its antifungal effect is 10 p.
The bactericidal effect is exhibited at about pm and about 60 ppm. A
While IT has such an excellent effect, it is difficult to handle due to its unique irritating odor. In particular, when it is used in foods, its irritating odor adversely affects the taste and aroma of the food itself. In addition, since AIT has high volatility and its bactericidal / bactericidal / mildew-proofing action is reduced in an extremely short time, when it is used for food, there is a problem in the sustainability of its effect. Therefore, a fungicide or antifungal agent containing AIT as an active ingredient,
Especially in the development of preservatives for food additives, AIT
It has been a problem to reduce the irritating odor of oneself and provide the food in a mode that does not affect the taste and aroma of the food itself. Further, since it has high volatility and its bactericidal / bactericidal / mildew-proofing action is reduced in an extremely short time, it was also an issue to improve its sustainability. From the above circumstances, the problem of the present invention is to provide a preservative that can impart excellent antifungal and bactericidal properties to food, has excellent safety, and does not affect the taste and aroma of the food itself. It is to provide the food containing it.

[0003]

[Means for Solving the Problems] The inventors of the present invention have conducted various researches to achieve the above-mentioned object.
It was found that a food containing a T cyclodextrin clathrate can solve the above problems at once, and has completed the present invention.

The present invention relates to a food containing a cyclodextrin clathrate of AIT.

The action of AIT in the food containing the cyclodextrin clathrate of AIT of the present invention is to suppress the growth of fungi that are invading from the outside during the storage and the sterilization of the fungi present in the raw materials of the food. It is a thing.

[0006] The AIT as used herein does not refer to a natural product or a synthetic product, and further, allyl isothiocyanate 10
Not only a single agent consisting of 0%, but also an essential oil containing this, for example, an extract from horseradish or mustard or a crudely purified product may be used.

The cyclodextrin used for the inclusion of AIT in the present invention includes α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, di-lower alkyl-β-cyclodextrin and / or 2-hydroxy lower alkyl-β-. Cyclodextrins, and mixtures thereof. In the cyclodextrin mentioned above, the carbon number of the lower alkyl group in the substituted cyclodextrin is usually in the range of 1 to 6. In the present invention, a particularly preferred cyclodextrin is β-cyclodextrin.

In the present invention, the inclusion of AIT in cyclodextrin is based on 1 part by weight of cyclodextrin.
AIT added to 0.01 to 0.15 parts by weight, preferably 0.02 to 0.05 parts by weight, to 1 to 3 parts by weight of water, preferably 1.2 to 1.5 parts by weight, It is carried out by stirring with a kneader or the like at 20 to 40 ° C. for 60 to 120 minutes.

In the present invention, AIT is used as a cyclodextrin clathrate, and the reason why cyclodextrin is suitable as a carrier is that the clathrate is AI.
This is because T is chemically stabilized, the volatilization of AIT vapor is gradually released to enhance the sustainability of its effect, and the irritating odor peculiar to AIT is alleviated, and eventually odor is eliminated. Also,
Cyclodextrin has a masking effect on taste components such as spiciness and bitterness, and the addition of AI to food has almost no effect on the original taste and aroma of the food. Moreover, cyclodextrin is mainly composed of non-reducing maltooligosaccharides, is rapidly metabolized in the body, has no toxicity, and is safely applied to foods.

Examples of foods suitable for incorporating AIT in the present invention with a cyclodextrin clathrate include breads, rice cakes, confectioneries (anko, yokan, buns, jellies, cakes, castella, cookies), dairy products. (Butter, margarine, cheese, yogurt, whipped cream), seafood paste (kamaboko, bamboo rings, fried tempura), processed meat (so-sage, ham, salami), processed fruit (jam, marmalade, fruit sauce), seasoning Food (soy sauce, miso, dressing, mayonnaise, ponzu, noodle soup, etc.), noodles (udon, soba), luxury items (pickles, boiled soup), and meat,
Examples include fish meat, fruit bottling, and canned foods.

The food containing the AIT cyclodextrin clathrate does not require a special step to contain the AIT cyclodextrin clathrate, and it is substantially mixed with the raw materials in the above-mentioned food manufacturing process. Can be manufactured through the same steps as usual.

In order to incorporate the cyclodextrin inclusion product of AIT into a food product, in the process until the product is completed, for example, from known methods such as mixing, kneading, dissolving, dipping, spraying, coating and spraying. The food may be selected and used according to the food to be contained.

In the food containing the AIT cyclodextrin clathrate of the present invention, the amount of AIT added to the food is 1 to 100 ppm, preferably 10 to 20 ppm.
Is exemplified.

[0014]

Industrial Applicability The food containing the cyclodextrin clathrate of AIT of the present invention has excellent mildew-proofing and bactericidal properties, in which the mold / bacteria generation / growth of the food during the distribution / preservation of the food is suppressed. It can be stored for a long period of time.
Further, since the food contains AIT in the form of a cyclodextrin clathrate, volatilization of AIT vapor is gradually released, and the antifungal and bactericidal effects of AIT are high and food safety is high. The problem does not occur in terms of.

EXAMPLES Examples will be given to explain the present invention in more detail, but the present invention is not limited thereto.

Reference Example 1 Preparation of Cyclodextrin Inclusion Product of AIT 100 parts by weight of liquid Celldex CH-20 (manufactured by Nippon Food Processing Co., Ltd.) plus 2 parts by weight of AIT was put in a kneader and left at room temperature for 1 hour. After stirring for an hour, an inclusion compound of cyclodextrin of AIT was obtained.

Example 1 Cyclodextrin inclusion AIT
Production of Food Containing (1) 100 parts by weight of red bean paste, 45 parts by weight of sugar, 0.5 AIT cyclodextrin inclusion product obtained in Reference Example 1
Parts by weight were added, heated with stirring, and kneaded to obtain a product. (2) Jam Raw strawberries (appropriately pears, apples, etc.) 1000 parts by weight, sugar 400 parts by weight, AIT cyclodextrin inclusion product 2 parts by weight obtained in Reference Example 1, pectin 3 parts by weight, and citric acid 0.6. A part was boiled down to obtain a product.

Test Example 1 The bean paste containing AIT obtained in Example 1 was stored in a thermo-hygrostat (28 ° C., 90% RH) for 7 days, and the generation of mold was visually observed. The results are shown in Table 1. As a comparative example, the state of mold development was also observed in the same manner as described above for the bean paste (control) not subjected to the mold prevention treatment, and the results are also shown in Table 1.
