Abstract

Deodorant compositions using a Mate extract have an advantage of having high safety with no side effect since the Mate extract is obtained from natural materials. However, these compositions suffer from a problem that the deodorant effect thereof is seriously deteriorated under weakly acidic conditions. To overcome this problem, disclosed is a deodorant containing a Mate extract which sustains a high deodorant effect even under weakly acidic conditions. By using a Mate extract together with laccase, a high deodorant effect can be achieved even under weakly acidic conditions where the deodorant effect of the existing deodorant compositions comprising a Mate extract is deteriorated. The strong bitterness and astringency of Mate can be reduced by preparing the Mate extract by a two-stage extraction method.

Description

Deodorant composition

The present invention relates to a deodorant composition characterized by containing laccase and mate tea extract, and a food or drink containing the same.

Conventionally, as a method for deodorizing and deodorizing malodors, a method of removing malodors by masking with an aromatic substance, chemical deodorization with an oxidizing agent, neutralizing agent, fixing agent, etc., or adsorption with activated carbon or the like has been used. It was. However, these methods often have significant restrictions depending on the purpose of use. Particularly in the food field, it is necessary to use substances that are safe for the human body when ingested.
Natural product extracts such as herbal medicines and herbs that have been used since ancient times have attracted attention as deodorants with excellent deodorizing effects that have solved these problems, and have been used since ancient times. It is known to have an effect (Patent Documents 1-7 and Non-Patent Documents 1-3). In particular, Non-Patent Document 2 describes a deodorizing effect by using a combination of chlorogenic acid, which is the main component of mate tea, and an apple extract having a polyphenol oxidase effect.

However, under the weakly acidic condition, there is a disadvantage that the deodorizing effect of the mate tea extract is significantly reduced. In order to enhance the deodorizing effect of mate tea extract in foods and drinks under mildly acidic conditions, it is necessary to use mate tea extract much more than the normal application amount, resulting in a deodorant composition Things are expensive. In addition, mate tea has a strong bitterness and astringency, and is easily subject to restrictions on the amount and flavor when commercialized. Therefore, it has been considered undesirable from the viewpoint of practical use to use a large amount of mate tea extract to enhance the deodorizing effect.

Calculated.
Methyl mercaptan deodorization rate (%) = (MB-MS) / MB × 100

(Example 1-5) Comparison of deodorizing effect Table 1 shows a comparison of the deodorizing effect on methyl mercaptan when laccase was not added to and added with 50 μg of various tea leaf extracts extracted under different extraction conditions. . Compared with other tea leaf extracts, mate tea extract had a very high deodorant effect, and the combination of mate tea water extract and laccase showed the strongest deodorant activity.

(Example 1-6) pH and deodorizing effect of mate tea water extract For an extract of mate tea water, the methyl mercaptan deodorization rate at different pHs by changing the pH of the reaction solution (Example 1-4) and It measured similarly.
The results are shown in FIG. Under mild acidity up to pH 4-7, the deodorization rate of the mate tea water extract was significantly increased by the addition of laccase.

Comparison of deodorizing effect between mate tea and strawberry tea In order to compare the deodorizing effect of a known odorous composition (Patent Document 8) containing a strawberry extract of the genus Rosaceae and laccase, (Examples) The following experiment was conducted using the extract of mate tea water extracted in 1-3) and the extract of strawberry tea water.

(Example 2-1) Measurement of 50% effective concentration (EC ₅₀ ) For extracts of mate tea and strawberry tea water, the deodorization rate at each concentration was obtained in the same manner as in Example 1 except that the sample concentration was changed. It was. Thereafter, the horizontal axis the logarithm of the sample concentration, to create a graph of the deodorization rate was the vertical axis to obtain the concentration (EC ₅₀₎ to obtain a 50% deodorization rate.
The prepared graph is shown in FIG. 2 and Table 2 shows the deodorizing effect of mate tea and tea tea water extract.
2. From FIG. 2, it was recognized that mate tea has a deodorizing effect on methyl mercaptan at a lower concentration than strawberry tea. Further, from Table 2, EC ₅₀ of mate tea was 20.53 μg / ml, and a deodorizing effect three times or more than that of strawberry tea was recognized.

Mate Tea Extraction Condition and Deodorizing Effect In order to evaluate the difference in odor eliminating effect depending on the mate tea extraction condition, methylate was extracted in the same manner as in Example 1 except that mate tea was extracted under different extraction conditions as follows. The deodorizing activity for mercaptans was evaluated.

(Example 3-1) Plant extraction method i) One-step extraction 1 L of extraction solvent was added to 50 g of dried plant powder, and reflux extraction was performed at 90 ° C for 1 hour. The extract was filtered, concentrated under reduced pressure, and lyophilized to obtain an extract. As the extraction solvent, water or water-containing ethanol with different concentrations was used.
ii) Two-stage extraction 1 L of ethanol was added to 50 g of dry powder of mate tea, reflux extraction was performed at 90 ° C. for 1 hour, and the extract was separated by filtration. Water or 1 L of 15% aqueous ethanol was added to the extraction residue obtained by filtration, and reflux extraction was performed at 90 ° C. for 1 hour. The extract was filtered, concentrated under reduced pressure, and lyophilized to obtain an extract.

(Example 3-2) Comparison of deodorizing effect Table 3 shows the deodorizing effect on methyl mercaptan when laccase was added to 20 μg of mate tea extract with different extraction conditions. In one-stage extraction, mate tea 15% ethanol extract showed the strongest deodorizing activity, followed by water extract, and the tendency was that deodorizing activity tended to be higher when the extraction solvent was aqueous. . In addition, in the case of strawberry tea belonging to the family Rosaceae, it is reported that the deodorizing effect is improved by performing two-stage extraction with water extraction after pretreatment with 100% ethanol (Patent Document 8). Therefore, mate tea was also subjected to two-stage extraction in which pretreatment with 100% ethanol was performed to evaluate the deodorizing effect. As a result of the test, the two-stage extraction did not significantly improve the deodorizing effect, but no decrease was observed.

Difference in taste depending on mate tea extraction conditions In order to evaluate the difference in taste due to mate tea extraction conditions, the following sensory test was performed using the mate tea extract extracted in Example 3 above with laccase added. went.

(Example 4-1) Sensory test A 0.25% (wt / v) aqueous solution was used for the sensory test of the mate tea extract. The inspection items were “bitterness”, “astringency”, “aftertaste”, “acidity”, and “sweetness”, and taste evaluation was performed according to the evaluation criteria shown in Table 4 by five panelists.

(Example 4-2) Comparison of taste The taste evaluation of mate tea extract (0.25% aqueous solution) by five panelists is shown in FIGS. 3A, 3B, 3C, 3D, 3E, and 3F. . 3A is one-step extraction with water, FIG. 3B is one-step extraction with 15% ethanol, FIG. 3C is one-step extraction with 60% ethanol, FIG. 3D is one-step extraction with 100% ethanol, and FIG. 3E is extraction with 100% ethanol. 3F shows the taste evaluation of the two-stage extraction with 15% ethanol, and the two-stage extraction with water after extraction with 100% ethanol. The higher the ethanol concentration of the extraction solvent, the higher the “bitter taste” and “astringency” scores. It was also confirmed that when the two-step extraction process was performed on the water extract and the 15% ethanol extract, the scores of “bitter taste” and “astringency” decreased.

Ingredient composition and deodorizing effect of mate tea extract and influence on taste In order to investigate the influence on taste of ingredient composition in mate tea extract, the following analysis was performed using the mate tea extracted in Example 3 above.

(Example 5-4) Ingredient composition Table 5 shows the contents of chlorogenic acid as a polyphenol component and caffeine, caffeic acid and saponin as taste components in mate tea extract. Since the caffeine content and the saponin content are low in the two-stage extract, it is considered that improvement was recognized in the items of “bitter taste” and “astringency” in the taste evaluation.

Contribution of chlorogenic acid in the deodorizing effect of mate tea extract In order to determine the chlorogenic acid contribution in 15% ethanol extract, which was the most active in mate tea extract in Example 3, mate tea was used in the same manner as in Example 2. The 50% effective concentration (EC ₅₀ ) of the extract and chlorogenic acid was measured, and the contribution rate of chlorogenic acid to the deodorizing activity was determined. A graph with the logarithm of the sample concentration on the horizontal axis and the deodorization rate on the vertical axis is shown in FIG. 4, and the 50% effective concentration (EC ₅₀ ) of mate tea extract and chlorogenic acid and the contribution ratio of chlorogenic acid are shown in Table 6. The contribution rate was calculated from each EC ₅₀ by the following formula.
Contribution rate = _{(EC 50} of _{EC 50} / chlorogenic acids mate) × (chlorogenic acid content in the mate (%) / 100)
From Table 6, since the contribution rate of chlorogenic acid is as low as 12.3%, it is considered that polyphenol components other than chlorogenic acid are also involved in the activity.
