Japanese Examined Patent Publication No. 3-61457 JP 2003-102821 A

  In patent document 1, as a deodorant component, the fruit-fruit juice liquid which does not carry out a fractionation process itself, or the sugar-free liquid itself which removed the saccharide | sugar content from this juice liquid, or those dehydration concentrates are contained in this, and the adjuvant for preparations in this It is characterized by adding. In this example, deodorization tests of trimethylamine, ammonia, hydrogen sulfide, acetaldehyde, and (acetic acid: Example 2) are performed as malodorous components in the examples, and the effect is obtained.

  Patent Document 2 is characterized in that a deodorant component is extracted with an alkaline aqueous solution from a substance containing polyphenols that are not as large as tannin and is used as a deodorant. In this example, deodorization tests of methyl mercaptan, ammonia, acetaldehyde, trimethylamine, and hydrogen sulfide are performed in the examples to obtain the effect.

However, Patent Documents 1 and 2 described above have problems in the following points.
In the experiment conducted in the example shown in Patent Document 1, the effect was mainly observed with respect to nitrogen-based malodor, but there was a problem that it did not act on sulfur-based malodor, particularly mercaptans.

  The juice of persimmon contains condensed tannin that is not decomposed by acid or alkali. This condensed tannin, which is a member of polyphenol, is a molecule that is much larger than flavonoids, so-called high-molecular tannin. The juice of persimmon has various effects such as deodorization, antibacterial action, and antioxidation in combination with the characteristics of this tannin, that is, the macromolecules, innumerable hydroxyl groups, and strong reducing power.

  Although the squeezed juice of potato has a strong reducing power due to tannin as its main component, sulfurous malodor is a chemically stable substance and is also reducing like tannin. Although soluble, no deodorizing effect due to chemical reaction is observed. That is, in Patent Document 1, a deodorizing effect cannot be expected for sulfur-based malodors.

  In Patent Document 2, a deodorizing component extracted from a rooibos tea with an alkaline aqueous solution as a substance containing polyphenols is particularly effective for sulfur-based malodors, particularly methyl mercaptan, for which a deodorizing effect was not recognized in Patent Document 1. Yes. In other words, rooibos tea itself is reducible, but by extracting it with an alkaline aqueous solution, it was possible to give this extracted deodorant component an oxidizing power that is opposite to the reducing power. Oxidizing power oxidizes sulfur-based malodor and exhibits a deodorizing effect.

  Rooibos itself is reducible because it contains flavonoids and polysaccharides such as quercetin in addition to many mineral components. However, the deodorant component has a lower content of tannin that enhances the reducing power than the squeezed juice of koji, and the amount of phenolic hydroxyl groups as a whole is considerably smaller. As a result, this deodorant component does not have as many functions as the squeezed squeezed juice, that is, functions such as antioxidant action.

  The problem to be solved is that, as in the above-mentioned Patent Document 1, the deodorant component using the squeezed juice of the strawberry cannot be deodorized by a chemical reaction with a sulfur-based malodor. As described above, the deodorant component extracted with an alkaline aqueous solution from a substance containing polyphenols having a smaller molecule than tannin and a small amount of phenolic hydroxyl group does not exhibit an antioxidant effect as much as that of squeezed juice.

The present invention, after obtaining a mixed solution was stirred and poured water to pressed juice of persimmon for the production method of the deodorant, the pH value by addition of aqueous sodium carbonate solution to 8.5-9.0 It is characterized by adjusting . In addition, the present invention is characterized in that the squeezed juice of koji produced by the above-described method with respect to the deodorant is a main component.

Since the deodorant of the present invention is mainly composed of squeezed squeezed juice, the squeezed squeezed juice itself exhibits an antioxidant effect due to the strong reducing power, and is “alkalized” as described later. However, since the sodium carbonate aqueous solution is added to the mixed solution of squeezed squeezed juice and water, it becomes possible to add an oxidizing power in addition to the reducing power described above. As a result, the squeezed squeezed juice With the chemical reaction, it is possible to deodorize reducing sulfur-based malodor that could not be deodorized.

In the method for producing the deodorant of the present invention , water is added to the squeezed juice of strawberry and stirred to obtain a mixed solution, and then an aqueous sodium carbonate solution is added to adjust the pH value to 8.5 to 9.0. Since the adjustment is made, it is possible to add an oxidizing power in addition to a reducing power without losing the original characteristics of the squeezed juice.

  The deodorant of the present invention is mainly composed of squeezed juice with a large tannin content of large molecules, and also has an additional oxidizing power along with the original characteristics of this squeezed juice. In addition, while maintaining the characteristics of the squeezed juice itself, it is possible to deodorize sulfur-based malodors that had no deodorizing effect with the squeezed squeeze solution with high efficiency.

  Since the sulfurous malodor itself is reducible, it can be easily deodorized by simply using a substance having an oxidizing power as a main component. However, if the main component is a substance having only an oxidizing power, it cannot be expected to have a deodorizing effect or an antioxidant effect as much as the squeezed juice of koji. On the other hand, squeezed squeezed juice can be said to be a substance that can obtain a deodorizing action and an antioxidant action extremely effectively. Then, it is conceivable to simply alkalize the squeezed juice, but this may cause the action itself of the squeezed juice, which has a strong reducing power, to disappear.

  Therefore, in the present invention, the squeezed juice liquid is not alkalized (extracted with an alkaline aqueous solution to increase the oxidizing power as in Patent Document 2), and the squeezed juice liquid has a strong reducing power. I thought about adding the characteristics of oxidizing power.

  Usually, if small molecules are used, the reducibility and the oxidizability cancel each other, and a substance cannot have both properties at the same time. However, the condensed tannin contained in the squeezed juice of a strawberry is a macromolecule, also called a polymer tannin, and has many phenolic hydroxyl groups in one molecule. In addition, this condensed tannin oxidizes a part of the hydroxyl group under alkaline conditions, and the oxidized part has an oxidizing power, while the rest remains unchanged and continues to have a reducing power. Show.

  As described above, the phenolic hydroxyl group easily binds to oxygen under alkaline conditions, and once oxidized, this time shows an oxidizing power. For example, “Tomoaki Matsuo, Agriculture and Horticulture, Vol. 75, No. 1, 3-13, 2000 ". As a simple example, it is known that when reducing diphenol is oxidized, it becomes a quinone having oxidizing power.

In other words, since the squeezed juice contains high-molecular tannin that is not decomposed by acid or alkali, adjusting the amount of sodium carbonate aqueous solution may impair the deodorizing and antioxidant effects due to the inherent reducing properties. In addition, the oxidized portion has an oxidizing power, and it is possible to deodorize the sulfur-based malodor that could not be deodorized with the squeezed juice of koji.

And in the manufacturing method of the deodorizer of this invention, it is desirable for the sodium carbonate aqueous solution to add that the hydrogen ion exponent pH after addition is 8.5-9.0, for example. This is because when the pH is lower than 8.5, the application of oxidizing power is insufficient, and when the pH is higher than 9.0, more reducing power is lost and the antioxidant action is weakened.

Also, the reason for using a carbonated aqueous solution of sodium, although other hydroxides may be used, a powerful drug, except that requires careful operation, undesirable in consideration of the application to the food. In addition, sodium citrate and sodium hydrogencarbonate were not able to dissolve the amount necessary for adjusting the pH of the squeezed juice of cocoon to about 8.5. From this, it has been found that a high concentration of salmon juice cannot dissolve so much salt.

  In this way, since the squeezed juice of koji is not completely alkalized, it becomes possible to add a characteristic of oxidizing power without impairing the characteristic of reducing power. In addition to the antioxidant and deodorant effects of the reductive nature of squeezed juice, it is possible to deodorize sulfur-based malodors that could not be deodorized until now due to the newly added oxidative properties of koji juice. It was.

The experiment and the result conducted in order to confirm the effect of this invention below are shown.
The deodorant (Example) according to the present invention has the following components and ratios.
・ Salmon juice 50.0 parts ・ Water 37.5 parts ・ Sodium carbonate aqueous solution (10%) 12.5 parts

The said deodorizer (Example) was manufactured as follows.
(1) Water is poured into the squeezed juice of the koji at room temperature.
(2) Stir for about 15 minutes.
(3) A sodium carbonate aqueous solution is gradually added at 100 ml / min until pH = 8.5.
(4) Stir for about 30 minutes.

The comparison object for confirming the effect of the deodorization which concerns on this invention used the following.
(Comparative Example 1) Strawberry juice (Comparative Example 2) Rooibos tea alkaline extract

  In the experiment, 1 g each of 5% diluted solutions of Example, Comparative Example 1 and Comparative Example 2 were put into a 1 L Erlenmeyer flask, and malodorous substances (ammonia, trimethylamine, acetaldehyde, formaldehyde, hydrogen sulfide, methyl mercaptan, A predetermined amount of valeric acid) was charged and sealed, and the malodor concentration after 30 minutes was measured with a Kitagawa type detector tube. Separately, the 1 L Erlenmeyer flask was charged with only the same amount of malodorous substance as described above, and the malodor concentration in the flask after 30 minutes was measured by the same method to obtain a blank test value. The measured numerical values of the experimental results are shown in Table 1 below, and a comparative graph based on the numerical values in Table 1 is shown in Table 2.

  As shown in Tables 1 and 2 above, as a result of the experiment, the examples of the present invention are the same or slightly higher or lower than those of Comparative Examples 1 and 2 with respect to ammonia, trimethylamine, acetaldehyde, formaldehyde, and isovaleric acid. Deodorization rate. In this regard, it can be said that the deodorization rate was practical level in both Example, Comparative Example 1 and Comparative Example 2.

  As a result of the experiment, it should be noted that in the examples of the present invention, the deodorization rate was improved to 70.0% for hydrogen sulfide in which Comparative Example 1 was 0.0% and Comparative Example 2 was 60.0%. In addition, the deodorization rate of methyl mercaptan, which was 6.2% in Comparative Example 1 and 52.4% in Comparative Example 2, was improved to 86.4%.

  From the above, the present invention can deodorize the malodorous substances that can be deodorized in Comparative Examples 1 and 2 and the malodorous substances that were difficult to deodorize in Comparative Examples 1 and 2 at a practical level. It turned out to be.

  In addition, since the deodorant of the present invention basically uses the squeezed juice of strawberry, it should have not only the deodorizing action described above, but also the antioxidant action inherent in the squeezed juice of strawberry. is there. Therefore, in the following experiment, it was confirmed to what extent the deodorant of the present invention retained the function of the original squeezed juice by the production method of the present invention.

  The deodorant of the present invention produced as described above and the squeezed juice of Comparative Example 1 were processed into powders by spray drying, using 1/10 of these trehalose as an excipient, and active oxygen. The erasing ability (unit / gm) was compared. The comparison results are shown in Table 3.

  From the above results, the deodorant of the present invention originally has the squeezed juice because the active oxygen scavenging ability, which is one measure of the reducing power, is almost equal to the value of the squeezed juice itself. It was found that the antioxidant effect due to the reducing power was not reduced so much.

In the present Example, the effect was confirmed by experimenting with a 5% diluent, but the deodorization rate was further increased (especially against sulfur-based malodor) when the diluent was 10%. Further, the present invention, since the addition of carbonated aqueous sodium not a poisonous and deleterious substance when viewed from the particular standpoint of food additives and handling. Furthermore, in the said Example, although it was set to pH = 8.5, even if it adjusts the addition amount of aqueous alkali solution and it adjusts in the range to pH = 9.0, the effect equivalent to the above or more is obtained. Can do.

In addition, the deodorant of the present invention can be used after being processed into a powder or liquid. Regarding use, if the alkali to be added is sodium carbonate, it can be added to food, adhered to human skin, to living space. There is no harm even if it is used for spraying.
