Description

Technical Field

[0001] This invention relates to the field of daily chemical products technology, and in particular to an aromatic deodorizing composition, its preparation method and application. Background Technology

[0002] The main sources of human body odor can be categorized as follows: ① Apocrine gland secretions are mostly proteins and oils, which ferment through the action of resident bacteria on the skin surface, producing unpleasant gases such as short-chain fatty acids, hydrogen sulfide, ammonia, and methyl mercaptan; ② Eccrine gland secretions are mostly small molecules such as urea and lactic acid, which further decompose into ammonia; ③ Residues in the mouth, under the action of harmful bacteria, form unpleasant odor components, mainly consisting of small molecules such as hydrogen sulfide, methanethiol, trimethylamine, indole, methylindole, and pyridine; ④ Gastrointestinal flora imbalance, abnormal metabolism, and the consumption of high-protein, high-sulfur foods produce foul odors from feces and urine, mainly consisting of ammonia, methylamine, hydrogen sulfide, methyl mercaptan, and aliphatic compounds (indole, acrolein, skatole).

[0003] The main categories of pet odor sources are: ① Odor sources such as odor glands, saliva, urine, and feces, which are more specific than human sources, such as pheromones, which are also a type of specific protein; ② Odors are mainly composed of three categories: nitrogen compounds (ammonia, methylamine), sulfides (hydrogen sulfide, methyl mercaptan), and aliphatic compounds (indole, acrolein, skatole, methane).

[0004] Based on the causes of odor production mentioned above, the solutions can be broadly categorized into three approaches: Ⅰ. Source fermentation: using active bacteria to degrade large protein molecules secreted by humans and pets, converting them into odorless molecules; Ⅱ. Mid-process antibacterial: reducing small odor molecules produced by harmful bacteria fermentation, such as oral bacteria (Porphyromonas gingivalis, Streptococcus mutans, Prevotella intermedia, Helicobacter pylori, Fusobacterium nucleatum, etc.) and surface harmful bacteria (Staphylococcus aureus, Escherichia coli); Ⅲ. Degradation of already produced odor molecules: using the main odor sources—ammonia (foul odor), trimethylamine (foot odor), hydrogen sulfide (rotten egg odor), and skatole (characteristic animal odor)—through neutralization and adsorption to achieve an inhibitory effect.

[0005] In the daily chemical industry, the international market offers a diverse range of pet odor-eliminating and deodorizing products. For example, China's pet market economy reached 340 billion yuan in 2024. Oral hygiene products and body odor-eliminating and deodorizing products within the daily chemical industry have also seen significant growth, which can be verified through the Meili Xiuxing data platform.

[0006] Furthermore, in the "Cosmetic Classification Rules and Catalog," the efficacy claims for cosmetics define fragrance as the function of modifying body odor and adding fragrance, while deodorization is defined as the function of reducing or masking body odor. Therefore, based on the aforementioned market demand and future trend predictions, there is an urgent need to develop a new type of deodorizing and neutralizing product that complies with the new cosmetic regulations, applicable to both the pet economy and the broader daily chemical industry, including oral care and cosmetics.

[0007] In conclusion, there is significant developmental value in how to better combine and utilize active monomers in products. This will allow for better solutions to odor sources while providing superior deodorizing and odor-eliminating effects to meet the needs of various products, including oral care, personal care, and pet products, thus achieving both desired and effective product efficacy. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide an aromatic deodorizing composition, its preparation method, and its application.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides a deodorizing composition comprising, by weight percentage, 0.1-0.7 wt% of a plant-derived active monomer and 0.05-6 wt% of a stationary phase, said stationary phase comprising zinc gluconate and pyrrolidone carboxylic acid.

[0010] This invention combines a stationary phase containing zinc gluconate and pyrrolidone carboxylic acid with plant-derived active monomers to form an aromatic deodorizing composition, which purposefully reduces odor molecules (isovaleric acid, ammonia, trimethylamine, hydrogen sulfide), inhibits Escherichia coli and lipid peroxidation, thereby achieving the deodorizing effect of aromatic deodorization.

Specifically, the paeonol is mainly derived from peony root bark extract, the eugenol is mainly derived from clove flower bud extract, and the nocarboxone is mainly derived from grapefruit fruit extract.

[0016] In a preferred embodiment of the aromatic deodorizing composition of the present invention, the aromatic plant-derived active monomer includes at least one of paeonol, eugenol, and nocaketone. Paeonol, eugenol, and nocaketone are respectively used as plant-derived medicinal aromas, floral aromas, and grapefruit peel aromas. Paeonol has analgesic, antibacterial, anti-inflammatory, and antioxidant effects; eugenol has analgesic, anti-inflammatory, and antibacterial effects in the oral cavity; nocaketone is often used in fragrances, as an insect repellent, and for its antioxidant properties. In this invention, experiments have demonstrated that at least one of paeonol, eugenol, and nocaketone, when combined with a stationary phase, effectively reduces the content of odor molecules (isovaleric acid, ammonia, trimethylamine, hydrogen sulfide), inhibits the growth of Escherichia coli and lipid peroxidation, and synergistically enhances the deodorizing and odor-neutralizing effects of the aromatic deodorizing composition.

[0017] As a preferred embodiment of the aromatic deodorizing composition of the present invention, the aromatic plant-derived active monomers are paeonol and nocacolone, and the mass ratio of paeonol to nocacolone in the aromatic plant-derived active monomers is paeonol:nocacolone = (1-6):1.

[0018] In a preferred embodiment of the aromatic deodorizing composition of the present invention, the mass ratio of paeonol to nocacolone in the aromatic plant-derived active monomer is paeonol:nocacolone = (2-5):1. The mass ratio of paeonol to nocacolone can also be at least one of 3:1 or 4:1.

[0019] In a preferred embodiment of the aromatic deodorizing composition of the present invention, the aromatic plant-derived active monomers are eugenol and nocacolone, and the mass ratio of eugenol to nocacolone in the aromatic plant-derived active monomers is eugenol:nocacolone = (1-6):1.

[0020] In a preferred embodiment of the aromatic deodorizing composition of the present invention, the mass ratio of eugenol to nocacolone in the aromatic plant-derived active monomer is eugenol:nocacolone = (2-5):1. The mass ratio of eugenol to nocacolone may also be at least one of 3:1 or 4:1.

[0021] As a preferred embodiment of the aromatic deodorizing composition of the present invention, the aromatic plant-derived active monomers are paeonol, eugenol and nocacolone, and the mass ratio of paeonol, eugenol and nocacolone in the aromatic plant-derived active monomers is paeonol: eugenol: nocacolone = (1-6): (1-6): 1.

[0024] In a preferred embodiment of the aromatic and deodorizing composition of the present invention, the mass ratio of zinc gluconate to pyrrolidone carboxylic acid in the stationary phase is zinc gluconate:pyrrolidone carboxylic acid = 1:(4-10). The present invention uses zinc gluconate and pyrrolidone carboxylic acid (PCA) as the stationary phase. Their main function is that zinc gluconate alone has a certain degree of crystallinity in the presence of water solubility, and after dissolving in water, it will form slow aggregation and reprecipitation. L-pyrrolidone carboxylic acid, as a human moisturizing factor, has strong hygroscopicity. Under the presence of PCA, it can combine with a certain amount of semi-hydrolyzed zinc gluconate, promoting the complete ionization of zinc gluconate, making it less prone to recrystallization and effectively improving the water solubility of zinc gluconate, enabling its application in various water-based products.

[0028] In a preferred embodiment of the aromatic deodorizing composition of the present invention, the auxiliary agent is a polyol.

[0029] In a preferred embodiment of the aromatic deodorizing composition of the present invention, the polyol includes, but is not limited to, at least one of glycerol, propylene glycol, butylene glycol and pentanediol.

[0030] In a preferred embodiment of the aromatic deodorizing composition of the present invention, the mass percentage of the adjuvant is 30-70 wt%. The mass percentage of the adjuvant may also be at least one of 40, 50, and 60 wt%, depending on the content of the plant-derived active monomer.

[0031] Secondly, the present invention provides a method for preparing the above-mentioned aromatic deodorizing composition, comprising the following steps: (1) Disperse zinc gluconate and pyrrolidone carboxylic acid in the stationary phase in water to obtain solution A; (2) Dissolve the plant-derived active monomer in the adjuvant to obtain solution B; (3) Mix the solution B obtained in step (2) with the solution A obtained in step (1) to obtain an aromatic deodorizing composition.

[0032] As a preferred embodiment of the preparation method of the present invention, in step (2), the adjuvant can be heated according to the solubility of the plant-derived active monomer.

[0033] Thirdly, the present invention provides the application of the above-mentioned aromatic deodorizing composition in the preparation of deodorizing and odor-neutralizing products.

[0036] As a preferred embodiment of the application described in this invention, the deodorizing products in the daily chemical field include, but are not limited to, oral deodorizers and / or body odor deodorizers and / or deodorizers and / or fresheners.

[0037] Fourthly, the present invention provides a product comprising the above-described aromatic deodorizing composition.

[0038] In a preferred embodiment of the product described in this invention, the product further includes auxiliary materials.

[0039] In a preferred embodiment of the product described in this invention, the excipients include, but are not limited to, at least one of solvents, thickeners, humectants, and preservatives.

[0040] In a preferred embodiment of the product described in this invention, the solvent includes, but is not limited to, at least one of water and alcohol.

[0041] In a preferred embodiment of the product described in this invention, the thickener includes, but is not limited to, at least one of sodium hyaluronate and sodium carboxymethyl cellulose.

[0042] In a preferred embodiment of the product described in this invention, the moisturizer includes, but is not limited to, at least one of glycerin and urea.

[0043] In a preferred embodiment of the product described in this invention, the preservative includes, but is not limited to, at least one of chlorphenesin and sodium benzoate.

[0045] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this invention, zinc gluconate and pyrrolidone carboxylic acid (PCA) are selected as stationary phases. Their main function is that zinc gluconate has a certain degree of crystallinity in the presence of water solubility, and will form slow aggregation and reprecipitation after dissolving in water. As a human moisturizing factor, L-pyrrolidone carboxylic acid has strong hygroscopicity. Under the presence of PCA, it can combine with a certain amount of semi-hydrolyzed zinc gluconate, promote the formation of complete ionization of zinc gluconate, and make it difficult for it to recrystallize and precipitate. This effectively improves the water solubility of zinc gluconate and enables zinc gluconate to be used in a variety of water-based products.

[0046] (2) The present invention combines a stationary phase containing zinc gluconate and pyrrolidone carboxylic acid with plant-derived active monomers to form an aromatic deodorizing composition, thereby purposefully reducing odor molecules (isovaleric acid, ammonia, trimethylamine, hydrogen sulfide), inhibiting Escherichia coli and lipid peroxidation, and thus achieving the effect of aromatic deodorizing. Attached Figure Description

[0047] Figure 1 The results show the stability test results of zinc gluconate-PCA solutions with different formulations in Example 1 of this invention. Detailed Implementation

[0048] To better illustrate the purpose, technical solution, and advantages of the present invention, the present invention will be further described below in conjunction with specific embodiments.

[0049] Unless otherwise specified, all other materials and reagents used in the examples, comparative examples, and effect examples are commercially available.

[0050] Example 1 To investigate the effect of pyrrolidone carboxylic acid (PCA) on the stability of zinc gluconate solution, multiple formulations were prepared according to Table 1, and the solution stability of zinc gluconate was evaluated. The preparation method was as follows: zinc gluconate and PCA were dissolved and dispersed in a small amount of water, 50 wt% propylene glycol was added, and water was added to make up to 100 wt% of the total mass percentage. The mixture was stirred evenly to obtain a zinc gluconate-PCA solution. The zinc gluconate-PCA solution was placed at room temperature (25℃) for 90 days, and the appearance changes of the solution were observed. The results are shown in Table 1 and [Table data missing]. Figure 1 .

[0051] Table 1 Formulation of Zinc Gluconate-PCA Solution As shown in Table 1 and Figure 1 As shown, without the addition of PCA, zinc gluconate at different concentrations exhibited varying degrees of turbidity. This is because zinc gluconate is easily hydrolyzed and oxidized to form precipitates, which, after standing for a period of time, will precipitate at the bottom. Furthermore, the amount of precipitate increases with the concentration of zinc gluconate (Formulas 8-9). Additionally, using PCA alone carries a certain risk of discoloration.

[0052] When the mass ratio of zinc gluconate to PCA is 1:10 to 1:4, the solution remains clear after 90 days at room temperature (25℃). When the mass ratio of zinc gluconate to PCA is 1:2 or 1:1, the transparency of the solution decreases and gray contents precipitate at the bottom, indicating that reducing the PCA content cannot improve the transparency of the solution or reduce precipitation. Therefore, choosing a zinc gluconate:PCA ratio of 1:(4-10) (mass ratio) can effectively improve the stability of zinc gluconate solution.

[0053] Examples 2-16 and Comparative Examples 1-8 Examples 2-16 and Comparative Examples 1-8 respectively provide an aromatic deodorizing composition and its preparation method. The aromatic deodorizing composition includes a plant-derived active monomer and a stationary phase. The components and amounts of the plant-derived active monomer are shown in Tables 2-3. The stationary phase includes zinc gluconate and PCA (mass ratio of zinc gluconate:PCA = 1:5). The preparation method includes the following steps: S1. Disperse zinc gluconate and PCA in water to obtain solution A; S2. Dissolve the plant-derived active monomer in propylene glycol at 70°C to obtain solution B. Mix solution B with 1.2 wt% of solution A obtained in step S1, and cool to room temperature (25 ± 2°C) to obtain an aromatic deodorizing composition. In the aromatic deodorizing composition, the mass percentage of propylene glycol is 50 wt%, and water is added to make up to a total mass percentage of 100 wt% for the aromatic deodorizing composition. The plant-derived active monomer includes paeonol, eugenol, and nocaketone.

[0059] Comparative Example 11 Comparative Example 11 provides an aromatic deodorizing composition and its preparation method. The composition of the aromatic deodorizing composition is similar to that of Example 4, except that the aromatic deodorizing composition does not contain a stationary phase. The preparation method includes the following steps: Plant-derived active monomers were dissolved in propylene glycol at 70°C to obtain solution B, which was then cooled to room temperature (25±2°C) to obtain an aromatic deodorizing composition. In the aromatic deodorizing composition, the mass percentage of propylene glycol was 50 wt%, and water was added to make up to a total mass percentage of 100 wt% for the aromatic deodorizing composition.

[0060] Comparative Example 12 Comparative Example 12 provides an aromatic deodorizing composition and its preparation method. The composition of the aromatic deodorizing composition is similar to that of Example 4, except that the aromatic deodorizing composition does not contain plant-derived active monomers. The preparation method includes the following steps: Zinc gluconate and PCA were dispersed in water to obtain solution A. Propylene glycol and water were added to obtain an aromatic deodorizing composition. In the aromatic deodorizing composition, the mass percentage of solution A was 1.2 wt%, the mass percentage of propylene glycol was 50 wt%, and water was added to make up to a total mass percentage of 100 wt% for the aromatic deodorizing composition.

[0061] Comparative Examples 13-14 Comparative Examples 13-14 respectively provide an aromatic deodorizing composition and a method for preparing the same. The components of the aromatic deodorizing composition are similar to those in Example 4, except that: In Comparative Example 13, the plant-derived active monomer was 0.22 wt% paeonol, while the remaining components and their amounts remained unchanged. In Comparative Example 14, the plant-derived active monomer was 0.22 wt% eugenol, while the remaining components and their amounts remained unchanged. The preparation method is the same as in Example 4.

[0062] Example 1 To evaluate the aromatic efficacy of the aromatic deodorizing compositions, the aromatic deodorizing compositions obtained in Examples 2-19 and Comparative Examples 1-14 were prepared into pet deodorizing products by adding 3 wt% of each of the compositions with 0.2 wt% sodium hyaluronate, 5 wt% glycerin, 0.2 wt% chlorphenesin, and 91.6 wt% water.

[0063] We are recruiting 20 volunteers to evaluate the fragrance efficacy (odor elimination effect, fragrance effect, and fragrance type) of pet deodorizing products using the following methods: The deodorization and odor removal levels are determined by comparing the deodorization and odor removal effects of competing products on the market with those of purified water. The best and worst results are then used to classify the products into four levels: Level I represents no inhibition effect, Level II represents partial (60%) inhibition effect, Level III represents most (80%) inhibition effect, and Level IV represents complete inhibition effect.

[0064] The fragrance effect is based on the cosmetic definition of modifying body odor and providing a pleasant scent. It is determined by statistically analyzing the subjective perception of fragrance odors. Fragrance type is determined by statistically analyzing the subjective degree of acceptance of the scent, and can be categorized as: ① has a scent but is very unpleasant, ② has a scent but is not pleasant, ③ is pleasant, and ④ is very pleasant.

[0065] The results are shown in Table 4-5.

[0066] Table 4. Evaluation results of odor-eliminating and deodorizing effects and fragrance effects of different aromatic odor-eliminating compositions. Table 5. Evaluation results of odor-eliminating and deodorizing effects and fragrance effects of different aromatic odor-eliminating compositions. As shown in Table 4-5, the optimal ratio of zinc gluconate and pyrrolidone carboxylic acid composition has a direct deodorizing effect, but it is not aromatic. By adding a certain amount and different ratios of one or more of paeonol, eugenol, and nocacolone, an aromatic effect can be provided, while improving the deodorizing effect and prolonging the deodorizing time.

[0067] As shown in Table 4, comparisons of Examples 2-5 and Comparative Examples 1-2 revealed that the combination of paeonol, eugenol, and nocacolone in specific ratios achieved good deodorizing and aromatic effects. Deodorizing and aromatic compositions obtained from combinations within unsuitable ratio ranges were unlikely to achieve a suitable aromatic effect. Comparisons of Examples 6-7, Examples 18-19, Comparative Examples 3-4, and Comparative Example 10 showed that plant-derived active monomers and stationary phases within specific dosage ranges achieved superior deodorizing and aromatic effects. If the dosage of plant-derived active monomers and stationary phases exceeded or fell below the specific range, the aromatic effect became too strong, resulting in an unpleasant odor (Comparative Example 4), or there was no aromatic odor at all, failing to achieve the desired deodorizing and aromatic effects.

[0068] As shown in Table 5, comparisons of Examples 8-10, Examples 12-14, and Comparative Examples 5-6 revealed that paeonol or eugenol, when combined with nocaketone in specific ratios, exhibited both deodorizing and aromatic effects, indicating that nocaketone, when combined with paeonol or eugenol, could achieve deodorizing and aromatic effects. Comparisons of Examples 11, Examples 15-16, and Comparative Examples 7-8 showed that specific dosages of plant-derived active monomers combined with the stationary phase could effectively enhance the deodorizing and aromatic effects of the aromatic deodorizing composition.

[0069] Example 2 To investigate and evaluate the aromatic deodorizing composition, the aromatic deodorizing compositions obtained in Examples 2-19 and Comparative Examples 1-14 were prepared with water at an addition amount of 3wt% to form purification products with a total mass percentage of 100wt% to treat gaseous pollutants.

[0070] I. The test method refers to the test method for gaseous pollutant purification in QB / T2761-2024 "Test Method for Purification Effect of Indoor Air Purification Products". The results are shown in Table 6-7.

[0071] 1. Test conditions 1) Ambient temperature: (25±2)℃ 2) Ambient humidity: (50±10) %RH 2. Test equipment Test chamber (1.5m) 3 Intelligent constant current atmospheric sampler, ultraviolet-visible spectrophotometer, and complex gas detector. 3. Testing Procedures 1) Sample preparation: Spray 100mL of sample onto 3 sheets of 1m thick paper. 2 The coating is applied in three coats to the base paper.

[0072] 2) Preparation of the release source: Place two glass rods wrapped with 5 layers of gauze upright into two 500mL reagent bottles, and fill each bottle with 200mL of pollutant ammonia (1%), and label them A1 and A2.

[0073] Hydrogen sulfide: Connect the gas cylinder containing hydrogen sulfide gas to the test chamber, open the gas cylinder valve, and the hydrogen sulfide gas will be generated into the test chamber.

[0074] Trimethylamine: Produced using a gaseous pollutant generator.

[0075] 3) Suspend the three base papers of the uncoated sample in the blank test chamber A, and then suspend the base paper of the coated sample in the test chamber B.

[0076] 4) Place release sources A1 and A2 into blank test chamber A and sample test chamber B respectively, and immediately close the chamber doors.

[0077] 5) Turn on the fans in compartments A and B respectively for 1 minute, then turn off the fans.

[0078] 6) After 24 hours of treatment, samples were collected from chambers A and B for testing and analysis, and the concentrations were recorded as CA and CB, respectively.

[0079] 4. Calculation formula Removal rate y (%) = (CA - CB) / CA × 100 (CA is the concentration in the blank chamber and CB is the concentration in the test chamber) Table 6. Removal rate of gaseous pollutants from different aromatic deodorizing compositions Table 7. Removal rate of gaseous pollutants from different aromatic deodorizing compositions As shown in Tables 6-7, comparing Examples 2-5, 8-10, 12-14, Comparative Examples 1-2, and 5-6, it can be seen that paeonol and / or eugenol and nocaketone all have good gaseous pollutant removal rates under specific ratio ranges. Among them, when the mass ratio of paeonol, eugenol, and nocaketone is 6:1:1, 1:6:1, and 5:5:1, the gaseous pollutant removal rate of the aromatic deodorizing composition is even better. If the three components, paeonol, or eugenol and nocaketone are not within the specific ratio range, the gaseous pollutant removal rate of the aromatic deodorizing composition shows a decreasing trend, indicating that only when the mass ratio of paeonol, eugenol, and nocaketone is (1-6):(1-6):1 can a good deodorizing effect be achieved.

[0080] Comparing Examples 6-7, 11, 15-16, 18-19, Comparative Examples 3-4, and 7-10, it can be seen that the plant-derived active monomers and stationary phases in the aromatic deodorizing composition need to be within a specific dosage range to achieve a good removal rate of gaseous pollutants. Furthermore, the zinc gluconate and PCA in the stationary phase need to be within a specific ratio range to achieve a superior removal rate of gaseous pollutants. If the dosage range of the plant-derived active monomers and / or the stationary phase is not within this range, the removal rate of gaseous pollutants in the aromatic deodorizing composition will decrease. This indicates that only when the plant-derived active monomers are 0.1-0.7 wt%, the stationary phase is 0.05-6 wt%, and the mass ratio of zinc gluconate to PCA in the stationary phase is 1:(4-10) can the aromatic deodorizing composition achieve excellent deodorizing effects.

[0081] Comparing Comparative Examples 11-14 with the Examples, it can be seen that the aromatic deodorizing composition needs to contain plant-derived active monomers and a stationary phase to have excellent gaseous pollutant removal rates. When the plant-derived active monomers are only paeonol or eugenol, the gaseous pollutant removal rate of the aromatic deodorizing composition shows a relatively obvious downward trend. This indicates that the present invention can effectively improve the gaseous pollutant removal rate of the aromatic deodorizing composition by combining paeonol and / or eugenol with nocaketone and by combining plant-derived active monomers with a stationary phase to achieve the effect of deodorizing and odor-removing.

[0083] Antimicrobial inhibition tests were conducted by inoculating samples with a bacterial suspension of a standard strain of Escherichia coli. The initial bacterial contamination was 10. 6CFU / mL, after inoculating test plates with different concentrations, residual bacteria were counted and the inhibition rate was calculated. The results are shown in Table 8-9.

Escherichia coli inhibition rates of different aromatic and deodorizing compositions As shown in Tables 8-9, comparing Examples 2-5, 8-10, 12-14, Comparative Examples 1-2, and 5-6, it can be seen that paeonol and / or eugenol and nocaketone all have good Escherichia coli inhibition rates under specific ratio ranges. Among them, when the mass ratio of paeonol, eugenol, and nocaketone is 6:1:1, 1:6:1, and 5:5:1, the Escherichia coli inhibition rate of the aromatic deodorizing composition is even better. If the three components, paeonol, or eugenol and nocaketone are not within the specific ratio range, the Escherichia coli inhibition rate of the aromatic deodorizing composition shows a decreasing trend, indicating that only when the mass ratio of paeonol, eugenol, and nocaketone is (1-6):(1-6):1 can the deodorizing effect be achieved by inhibiting Escherichia coli.

[0085] Comparing Examples 6-7, 11, 15-16, 18-19, Comparative Examples 3-4, and 7-10, it can be seen that the plant-derived active monomers and stationary phases in the aromatic deodorizing composition need to be within a specific dosage range to achieve a good Escherichia coli inhibition rate, and the zinc gluconate and PCA in the stationary phase need to be within a specific ratio range to achieve a superior Escherichia coli inhibition rate. If the dosage range of the plant-derived active monomers and / or the stationary phase is not within this range, the Escherichia coli inhibition rate of the aromatic deodorizing composition will decrease. This indicates that only when the plant-derived active monomers are 0.1-0.7 wt%, the stationary phase is 0.05-6 wt%, and the mass ratio of zinc gluconate to PCA in the stationary phase is 1:(4-10) can the aromatic deodorizing composition achieve excellent deodorizing effects.

[0086] Comparing Comparative Examples 11-14 with the Examples, it can be seen that the aromatic deodorizing composition needs to contain plant-derived active monomers and a stationary phase to have an excellent Escherichia coli inhibition rate. When the plant-derived active monomer is only paeonol or eugenol, the Escherichia coli inhibition rate of the aromatic deodorizing composition shows a more obvious downward trend. This indicates that the present invention can effectively improve the Escherichia coli inhibition rate of the aromatic deodorizing composition by combining paeonol and / or eugenol with nocaketone and by combining plant-derived active monomers with a stationary phase, so as to achieve the deodorizing and odor-removing effects.

[0087] III. The lipid peroxidation inhibition rate was determined using the ferric thiocyanate method (FTC), and the specific protocol is as follows: (1) Required reagents and instruments: The water used was laboratory-grade water; For the methanol solution, take 80 mL of methanol and dilute it with water to 100 mL. Linoleic acid solution (2.5%), linoleic acid (Maclean, purity 99.0%, CAS: 60-33-3), prepared with anhydrous ethanol; Anhydrous ethanol; 75v / v% ethanol; PBS buffer (pH=7.0): Take 39.0 mL of 0.05 mol / L NaH2PO4 and 61.0 mL of 0.05 mol / L Na2HPO4 and mix well. Ammonium thiocyanate solution (30wt%): Weigh 30g of ammonium thiocyanate and dissolve it in 100mL of water; Hydrochloric acid solution (3.5 v / v%): Measure 8.8 mL of reagent hydrochloric acid and dilute with water to 100 mL; Ultraviolet-visible spectrophotometer, electric thermostatic incubator.

[0088] For the reference solution, take 2.0 mL of methanol solution, add 2 mL of linoleic acid solution and 4 mL of PBS buffer, and then perform the determination.

[0089] Sample solution: Weigh the sample and dissolve it in methanol solution to obtain the sample solution to be tested; take 2 mL of the above sample solution, add 2 mL of linoleic acid solution and 4 mL of PBS buffer, and perform the blank test with methanol solution; the final concentration of the aromatic deodorizing composition in the sample solution is 30 mg / mL.

[0090] (2) Specific operation: First, place the control solution and the sample solution in a constant temperature incubator at 40℃ for 120h. Take 0.1mL of the sample solution, add 4.7mL of 75% ethanol solution, 0.1mL of 30% ferric thiocyanate solution, and 0.1mL of ferrous chloride solution, and mix well. After standing for 3min, measure the absorbance value of the mixture at a wavelength of 500nm. Calculate the linoleic acid peroxidation inhibition rate according to the following formula. The results are shown in Table 10-11: Linoleic acid peroxidation inhibition rate = [1-(OD)] 样品 / OD 对照 ))×100% Table 9. Lipid peroxidation inhibition rate of different aromatic deodorizing compositions Table 10 Lipid peroxidation inhibition rate of different aromatic and deodorizing compositions As shown in Tables 8-9, comparing Examples 2-5, 8-10, 12-14, Comparative Examples 1-2, and 5-6, it can be seen that paeonol and / or eugenol and nocaketone all have good lipid peroxidation inhibition rates under specific ratio ranges. Among them, when the mass ratio of paeonol, eugenol, and nocaketone is 6:1:1, 1:6:1, and 5:5:1, the lipid peroxidation inhibition rate of the aromatic deodorizing composition is even better. If the three components, paeonol, or eugenol and nocaketone are not within the specific ratio range, the lipid peroxidation inhibition rate of the aromatic deodorizing composition shows a decreasing trend, indicating that only when the mass ratio of paeonol, eugenol, and nocaketone is (1-6):(1-6):1 can the deodorizing effect be achieved by inhibiting oil peroxidation.

[0091] Comparing Examples 6-7, 11, 15-16, 18-19, Comparative Examples 3-4, and 7-10, it can be seen that the plant-derived active monomers and stationary phases in the aromatic deodorizing composition require specific dosage ranges to achieve a good lipid peroxidation inhibition rate. Furthermore, zinc gluconate and PCA in the stationary phase require specific ratio ranges to achieve a superior lipid peroxidation inhibition rate. If the dosage ranges of the plant-derived active monomers and / or the stationary phase are not within these ranges, the lipid peroxidation inhibition rate of the aromatic deodorizing composition will decrease. This indicates that only when the plant-derived active monomers are 0.1-0.7 wt%, the stationary phase is 0.05-6 wt%, and the mass ratio of zinc gluconate to PCA in the stationary phase is 1:(4-10) can the aromatic deodorizing composition achieve excellent deodorizing effects.

[0092] Comparing Comparative Examples 11-14 with the Examples, it can be seen that the aromatic deodorizing composition needs to contain plant-derived active monomers and a stationary phase to have excellent lipid peroxidation inhibition rate. When the plant-derived active monomer is only paeonol or eugenol, the lipid peroxidation inhibition rate of the aromatic deodorizing composition shows a more obvious downward trend. This indicates that the present invention can effectively improve the lipid peroxidation inhibition rate of the aromatic deodorizing composition by combining paeonol and / or eugenol with nocacolone and by combining plant-derived active monomers with a stationary phase to achieve the effect of deodorizing and odor removal.

[0093] Furthermore, since the aromatic deodorizing composition of the present invention is a transparent solution, in addition to the product formulation used for testing described above, the amount added can be 0.1-99.99 wt%, and all of them can be used in the field of deodorizing and aromatic products. According to the above composition and the use of the invention, they are all within the scope of protection of this patent.
