  The present invention will be specifically described by the following formulation examples and test examples, but the present invention is not limited to these formulation examples and test examples.

  100 ml of a hydrogen sulfide standard solution for detecting 18 ppm of hydrogen sulfide gas was placed in a 300 ml Erlenmeyer flask and filled with the gas. To each flask, a deodorant prepared by previously mixing matcha powder and sodium hydrogen carbonate at a certain ratio was added to 100 mg / liter, sealed, lightly shaken for 1 minute, and reacted for 3 hours. The hydrogen sulfide gas concentration was measured with a gas detector tube (manufactured by Gastec Co., Ltd.). The measurement results are shown in Table 1.

  From the results of Table 1, the concentration of hydrogen sulfide can be reduced by using matcha tea and sodium hydrogen carbonate together.

As in Example 1, 100 ml of a standard ammonia aqueous solution for detecting 200 ppm of ammonia gas was placed in a 300 ml Erlenmeyer flask to fill the gas. To each flask, a deodorant prepared by previously mixing powdered green tea powder and sodium hydrogen carbonate at a certain ratio was added to 100 mg / liter, sealed, lightly shaken for 1 minute, and reacted immediately. The concentration was measured with a gas detector tube. Moreover, the change of the odor by a sensory test was also investigated. In the sensory test, 6 panelists evaluated the following 6 levels, and the average of all evaluations was calculated. The measurement results are shown in Table 2.

(sensory evaluation)
0 ... No ammonia odor 1 ... Slightly sensible ammonia odor 2 ... Relatively easily sensible ammonia odor 3 ... Medium ammonia odor 4 ... Slightly strong ammonia odor 5 ... Strong ammonia odor

  From the results of Table 2, the concentration of ammonia can be reduced by using matcha tea and sodium bicarbonate together.

  100 ml of a hydrogen sulfide standard solution for detecting 10 ppm of hydrogen sulfide gas was placed in a 300 ml Erlenmeyer flask to fill the gas. To each flask, a deodorant prepared by previously mixing matcha powder and sodium carbonate in a certain ratio was added to 100 mg / liter, sealed, lightly shaken for 1 minute, allowed to react, and left for 1 hour. Then, the hydrogen sulfide gas concentration was measured with a gas detector tube (manufactured by Gastec Corporation). As a comparative test, the same measurement was performed for calcium carbonate instead of sodium carbonate. The measurement results are shown in Tables 3 and 4.

  From the results of Table 3 and Table 4, the concentration of hydrogen sulfide can be reduced by using matcha tea and sodium carbonate in combination. However, even when matcha and calcium carbonate were used in combination, the concentration of hydrogen sulfide could not be reduced.

  100 ml of a hydrogen sulfide standard solution for detecting 12 ppm of hydrogen sulfide gas was placed in a 300 ml Erlenmeyer flask to fill the gas. To each flask, a deodorant prepared by mixing powdered green tea powder and magnesium oxide in a certain ratio in advance was added to 50 mg / liter, sealed, lightly shaken for 1 minute and allowed to react for 1 hour. Then, the hydrogen sulfide gas concentration was measured with a gas detector tube (manufactured by Gastec Corporation). Table 5 shows the measurement results.

  From the results of Table 5, the concentration of hydrogen sulfide can be reduced by using matcha tea and magnesium oxide in combination.

  Dehydrated cake of activated sludge from a food factory is placed in 500 ml plastic bottles in an amount of 100 g each, and 2,000 mg of deodorant prepared by previously mixing green tea powder and sodium hydrogen carbonate at a certain ratio in each plastic bottle. The mixture was sealed and lightly shaken 2 or 3 times, then allowed to stand at room temperature for 2 days, and the change in sludge odor was evaluated by a sensory test. The sensory test was conducted by 6 panelists, and the average of all evaluations was compiled. The evaluation results are shown in Table 6. In addition, Table 7 shows numerical values obtained by plotting them on the XY coordinates.

  From the results shown in Tables 6 and 7, the deodorant containing green tea and sodium bicarbonate was able to alleviate the sludge odor. In contrast, a masking agent, a microbial deodorant, sodium bicarbonate alone, and matcha alone did not provide a satisfactory deodorizing effect.

  The soil of kerosene odor soil from the site of the chemical factory is subdivided into vinyl bags of 500 g each, and each bag is filled with deodorant mixed beforehand with a certain ratio of green tea powder and sodium bicarbonate. The vinyl bag was inflated to about 5 times the volume of the soil, and the mouth was stopped with a rubber band and shaken vigorously 50 times. After leaving these for about 1 hour, as in Example 3, a sensory test was conducted with 6 panelists to evaluate the degree of relaxation of kerosene odor. The evaluation results are shown in Table 8. In addition, Table 9 shows numerical values obtained by plotting them on the XY coordinates.

  From the results of Table 8 and Table 9, the deodorant containing green tea and sodium bicarbonate was able to alleviate the kerosene odor. On the other hand, a satisfactory deodorizing effect could not be obtained with a masking agent, sodium bicarbonate alone, or matcha tea alone.

It can be applied as an industrial deodorant for various odors generated from various wastewaters, sewage treatment plants, human waste treatment plants, etc., dredged soil, sludge, sludge, and residual soil generated at construction sites.
