[Industrial Application Field] The present invention relates to a deodorizing composition used for odor removal, deodorization, and deodorization. [Conventional technology] Conventionally, deodorization and deodorization have involved (1) masking with fragrance;
(2) due to chemical reactions, etc., (3) due to physical adsorption, and (4) due to prevention of spoilage using fungicides. [Problems to be Solved by the Invention] However, as described above, the conventional deodorizing method has the following drawbacks. (1) Masking with fragrances was an auxiliary measure and did not provide a fundamental solution; on the contrary, the discomfort caused by fragrances often became a problem. (2)
Methods based on chemical reactions have the disadvantage that acids, alkalis, or oxidizing agents are difficult to apply to human environments due to their irritation and toxicity. (3) Physical adsorption methods, such as activated carbon and zeolite, have many limitations in their use in closed spaces, refrigerators, etc. (Four)
Methods that use disinfectants to prevent spoilage have the disadvantage that even though deodorization is effective as a preventive measure, they do not work immediately, and their bactericidal properties hinder purification through biodegradation. [Means for solving the problem] As a result of extensive research, the present inventors found that by using a composition containing a compound of chitosan, which is obtained by deacetylating chitin, and an organic acid and/or an inorganic acid, We discovered that a good deodorizing effect can be obtained.
Based on this knowledge, the present invention was completed. That is, the present invention is a deodorizing composition characterized by containing a compound of chitosan and an organic acid and/or an inorganic acid. The composition of the present invention exhibits an extremely good deodorizing effect on malodorous substances compared to commercially available products, and the chitosan of the composition of the present invention has a high level of toxicity and safety, such as crabs, shrimps, etc., which are eaten as food. The composition of the present invention is non-irritating and odorless, and can be prepared as a solution or powder, and is suitable for household use. From to industrial use,
It can be used in a wide variety of ways, either as it is or processed into fibers, cloth, nonwoven fabrics, resins, etc. The chitosan used in the present invention is obtained by de-N-acetylating chitin and is well known (e.g., Japanese Patent Publication No. 10150/1983, Japanese Patent Publication No. 441/1983) due to its molecular weight, etc. It is not limited. Further, examples of organic acids that can be used in the present invention include acetic acid, formic acid, propionic acid, maleic acid, benzoic acid, citric acid, tartaric acid, malic acid, ascorbic acid, and lactic acid. As the inorganic acid, hydrochloric acid, nitric acid, perchloric acid, sulfamic acid, sulfanilic acid, etc. can be used. Furthermore, organic acids may include those of natural origin, such as acetic acid such as wood vinegar and table vinegar. The preparation of the composition of the invention can be carried out, for example, by adding 0.36 ml of acetic acid.
A transparent to slightly cloudy solution is obtained by adding 1 g of chitosan to a % aqueous solution and stirring at room temperature or while heating. The pH of this liquid is 4.3. Then, depending on the application, use a sodium hydroxide aqueous solution.
PH adjustment can be performed. Adjustments can be made in the same way when using other acids. Example 1 1 g of snow crab pieces were heated in a 45% aqueous sodium hydroxide solution at 110°C for 4 hours and washed with water.
of chitosan at 0.05% of each organic acid shown in Table 1.
The composition of the present invention was prepared by dissolving it in 200 ml of a 4% aqueous solution and adjusting the pH to 6.0 with a 0.005% aqueous sodium hydroxide solution, and each malodorous substance was placed in a separately prepared 450 liter stainless steel odor test box. After injecting the test box with a syringe, sealing it and leaving it for 10 minutes while rotating the fan, 20 ml of the composition of the present invention was sprayed into the test box using a hand sprayer from the upper spray port, and the test box was sealed again and the fan was turned. After 1, 3, and 5 minutes of being left at room temperature, the fan was stopped, and the air inside the test box was sampled with a syringe and quantified using a gas chromatograph. A separate blank test was conducted to determine the residual rate of each malodorous substance. The results are shown in Table 1.
