Description

[Detailed Description of the Invention] [Field of industrial application] The present invention relates to a sustained-release ethanol preparation suitable for storage of foods.

[Prior art]

As a mildew-proofing technique for packaged foods, a method using ethanol gas, that is, a method in which an ethanol agent is sealed in an ethanol gas permeable container and placed in the packaging container when the food is packaged is widely used. Foods for which this method is used include Western confectionery, Japanese confectionery, noodles, and dried fish products.

[Problems to be solved by the invention] Ethanol gas gradually diffuses from the container containing the ethanol agent placed in the food packaging system into the space in the food packaging system, and the diffused ethanol gas is spread on the surface of the food. It is adsorbed, dissolves, forms an ethanol layer, and exhibits an antifungal effect. The antifungal effect is exhibited by the ethanol agent,
Deterioration of the flavor of food is often a problem due to volatile impurities having a low boiling point in the ethanol agent.

[Means for solving problems]

As a result of various investigations for solving the above problems, the present inventors have found that the deterioration of the flavor of foods can be suppressed by using a conventional sustained-release ethanol agent in combination with a substance having a solid amino group.

The present invention has been completed based on the above findings.

That is, the present invention is a substance having ethanol and a solid amino group adsorbed to an adsorbent (excluding ion exchangers).
The present invention relates to a sustained release ethanol preparation containing

Examples of the adsorbent for adsorbing ethanol used in the present invention include paper, cotton and cellulose powder, methyl cellulose, starch, dextrin, carboxyvinyl polymer,
Powders of silicon dioxide, talc, zeolite, ceviolite, loess, kaolin, diatomaceous earth, bentonite, perlite, clay, alumina and the like can be mentioned, but silicon dioxide is preferable, and a substance having a solid amino group described later is also used. You can.

The amount of ethanol adsorbed on these adsorbents depends on the amount of adsorbent 10
Ethanol 30 parts by weight or more with respect to 0 parts by weight, preferably 5
0 to 100 parts by weight, more preferably about 60 to 80 parts by weight.

Examples of the substance having a solid amino group used in the present invention include amino acids and high molecular amines, and high molecular amines are preferable.

Examples of amino acids include α-amino acids such as glycine, glutamic acid, lysine, and arginine.

The polymer amine is not particularly limited as long as it contains a primary amine, a secondary amine, a tertiary amine, and / or a quaternary amimonium in the polymer, but preferably a polyamino acid,
Examples thereof include polymers having amino sugars.

The polyamino acid is not particularly limited, and examples thereof include polylysine, polyalanine, polyglutamic acid, polyglycine,
Homopolymers such as polyarginine, poly (alanine-
Glycine), a glutamic acid-γ-methyl-eletane copolymer, and the like, and those having a basic amino acid such as lysine or arginine as a constituent are preferable. The average molecular weight is not particularly limited, but for example, about 6000 to 10000 is practical. The particle size is 10 mesh or less, preferably 50 mesh or less,
More preferably, it is about 100 to 250 mesh.

Examples of polymers having amino sugars include polysaccharides composed of amino sugars such as chitin and chitosan.

In the present invention, the proportion of ethanol and the substance having an amino group is 100 parts by weight of the former and 1 part by weight or more of the latter, preferably 3 to 1000 parts by weight, more preferably 5 to 300 parts by weight.
It is about part by weight.

The sustained-release ethanol preparation of the present invention may be produced, for example, as follows. That is, ethanol may be adsorbed on an adsorbent, then mixed with a substance having an amino group, and then sealed in an ethanol gas permeable container. The ethanol to be enclosed is generally adsorbed by an adsorbent and made into a powder form, but may be enclosed in any shape such as a granular form, a pellet form or a tablet form.

The amount of ethanol adsorbed on the adsorbent enclosed here varies depending on the purpose of use, but is usually 0.2
It is about 8 g.

〔effect〕

 Next, the effects of the present invention will be shown by experimental examples.

Experimental Example (1) Sample A substance having a certain amount of amino groups was added to and mixed with 10 g of an adsorbent obtained by adsorbing 70 parts by weight of ethanol on 100 parts by weight of silicon dioxide, and then this powder was a sachet in which washi was laminated on perforated polyethylene. Was filled and sealed to obtain a sample of the present invention. A control sample was prepared by filling and sealing only 10 g of the adsorbent in the pouch.

(2) Experimental method The sample was put in a 100 ml container, and the degree of pungent aroma in the container was examined by a sensory test.

(3) Experimental results The results are shown in Table 1.

As is clear from Table 1, the stimulating aroma is significantly reduced in the ethanol preparation of the present invention as compared with the conventional sustained release ethanol preparation.

Therefore, the present invention is expected as a food preservative with little deterioration in flavor.
