SUMMARY OF THE INVENTION An object of the present invention is to provide a pet deodorant which can be obtained by an inexpensive and simple method, has high safety for pets, and has high efficacy.

[0004]

Means for Solving the Problems In order to achieve the above object, the present inventors have conducted intensive studies, and as a result, the acid extract of wheat bran derived during the milling of wheat is effective as a deodorant. The inventors have found that the present invention has been completed.
That is, the present invention relates to a pet deodorant comprising, as an active ingredient, a wheat bran extract or a neutralized product thereof using an aqueous solution containing at least one organic acid. The wheat bran extract thus obtained can be used as a pet deodorant as it is. However, since the wheat bran extract has a slight wheat odor, removing or reducing the wheat odor can be a more preferable pet deodorant. The present inventors have found that this object can be achieved by steam-treating the above-mentioned wheat bran extract or by adding cyclodextrin to the above-mentioned deodorant, and furthermore, a more preferable pet deodorant. Completed. Therefore, the present invention also provides the above pet deodorant, wherein the wheat bran extract has been subjected to steam treatment, and the above pet deodorant, further comprising cyclodextrin. About.

[0005] The acid extract of wheat bran, which is an active ingredient of the present invention, has an effect of improving microbial production (JP-A-1-231840).
No.) and the effect of enhancing mushroom culture (Japanese Unexamined Patent Publication No.
) And can be produced by the method described in the above publication. As the organic acid used for extracting wheat bran, lactic acid, citric acid, malic acid, fumaric acid, and acetic acid, which can be used as food additives, are preferable. These organic acids are desirably in the form of 0.001 to 0.2 mol aqueous solution. In the extraction, the ratio of the wheat bran to the acid aqueous solution is desirably 100 to 1000 parts by weight of the acid aqueous solution with respect to 100 parts by weight of the wheat bran. The extraction operation may be performed by adding an acid solution to wheat bran and stirring with an appropriate mixer such as a propeller mixer for 5 to 30 minutes, and the temperature at this time may be 5 ° C to 50 ° C, generally room temperature. Subsequently, solid-liquid separation is performed by a known method to obtain an extract. It is simple to first perform pressure filtration, then centrifuge the filtrate and collect the supernatant. The obtained extract may be neutralized with a base such as sodium hydroxide, sodium carbonate, potassium hydroxide and the like. Thereafter, the concentrate is concentrated, and the obtained concentrate can be used as a deodorant as it is. However, it is preferable to further dry the powder to improve storage stability. When dextrin is added in an amount of about 20 to 30% during drying, there is an advantage that powdering is easy. As a drying method, any of known techniques such as spray drying, hot air drying, and vacuum freeze drying can be used. The acetic acid extract can remove volatile acetic acid by concentration and drying.

In order to remove the wheat odor of the wheat bran extract, for example, the powder of the wheat bran extract can be subjected to steam treatment. Alternatively, steam treatment may be performed in the course of the extraction step to the powdering step. Specifically, for example, a solution obtained by dissolving an extract or powder before drying in water is placed in a tank, and steam is passed through the tank to remove odor. As a condition for the steam treatment, it is appropriate to pass steam at 1 atm for 1 hour to a solution obtained by adding 15 liters of water to 15 liters of the extract before drying or 2 kg of the powder extract. The wheat odor can be removed by further adding cyclodextrin to the deodorant of the present invention. For example, wheat odor can be removed by adding 0.1 to 80% by weight, preferably 1 to 50% by weight, of cyclodextrin to the powder of wheat bran extract. Further, cyclodextrin may be added in advance and deodorized during the process from the extraction step to the powdering step. In particular, it is preferable to mix the solution with the solution before powdering and to dry-powder it. As cyclodextrins, α, β, γ and mixtures thereof are commercially available, and the cyclodextrin used in the present invention may be any of these types. Cyclodextrin containing α-type as a main component, which is inexpensive for food, is simple and has a sufficient effect of removing wheat odor.

The pet deodorant of the present invention can be used for general domestic animals such as dogs and cats, as well as for domestic animals and laboratory animals. As a method of using the pet deodorant of the present invention, firstly, the deodorant can be mixed with pet dung and urine litter. When a sheet such as a nonwoven fabric is used instead of sand, it can be filled therein. In addition, it can be sprayed directly onto the pet's body or litter as a solution. Since the pet deodorant of the present invention is an extract of an edible material, it is highly safe for animals, and there is no particular limitation on the amount of the deodorant used. Can be changed to The amount of the pet deodorant of the present invention is generally 0.01 to 30% by weight, more preferably 0.1 to 30% by weight based on the litter.
15% by weight. When used as an aqueous solution, the concentration of the aqueous solution is generally 1 to 30% by weight, more preferably 5 to 20% by weight. The pet deodorant of the present invention can be used in combination with a preservative such as an antioxidant and an antibacterial agent.
