Description

[Technical Field]

[0001] The present invention relates to a deodorizing composition for food and beverage production lines used to deodorize production facilities and equipment in food and beverage factories, etc., and a deodorizing and cleaning method using this deodorizing composition. [Background technology]

[0002] In food and beverage manufacturing plants, where a variety of different products are manufactured on the same production line, it is necessary to clean the production line every time a new product is changed to prevent contamination with the previous product remaining on the line. Food and beverage manufacturing plants use CIP (Cleaning in Place) cleaning, which cleans the inside of manufacturing equipment and machinery in its original state without disassembling it. In CIP cleaning, a cleaning solution is circulated or sprayed inside the manufacturing equipment, etc., but flavor odors tend to adhere and remain on the packing (seal) of the piping connections, and thorough cleaning is required to fully remove the flavor odor, which requires a great deal of effort. In particular, in recent years, the number of types of products being manufactured has increased, and the frequency of product changeover has also increased, requiring increased production speed for each product. However, in order to adequately remove the diversifying flavor odors, long cleaning and deodorization work is required, which is causing a significant decrease in productivity.

[0003] Instead of CIP cleaning, there is also the method of disassembling and cleaning the manufacturing equipment, but disassembling and reassembling the equipment every time the manufactured product is changed is labor-intensive and unrealistic. In addition, even if the equipment is disassembled, it is not easy to completely remove flavor odors that adhere to the packing parts, for example, by cleaning.

[0004] Conventionally, in order to remove flavor odors adhering to production lines in food factories, beverage factories, etc., methods have been adopted in which the production lines are treated with acidic and / or alkaline cleaning agents, or the lines are cleaned with acidic or alkaline cleaning agents and then deodorized using oxidizing agents such as sodium hypochlorite, peracetic acid, percarbonate, or perborate. However, these methods do not always provide sufficient deodorizing effects. In light of this situation, technologies have been proposed to further improve the efficiency of flavor removal in CIP cleaning. These include a deodorizing composition for CIP cleaning containing a solvent (A) and a surfactant (B) having an SP value of 6 to 9 at 25°C (see Patent Document 1 below); a deodorizing composition for CIP containing (A) a specific nonionic surfactant having an HLB value of 8 to 18, (B) a nonionic surfactant with an HLB value of less than 8, (C) a water-soluble solvent having an SP value of more than 9 at 25°C, and (D) water (see Patent Document 2 below); a deodorizing composition for CIP cleaning containing a specific nonionic surfactant such as a polyoxyalkylene fatty acid ester as the main component (see Patent Document 3 below); and a deodorizing composition for food and beverage production lines containing (A) an ether ester-type nonionic surfactant, (B) a polyoxyalkylene alkyl ether, (C) a sorbitan fatty acid ester, (D) a glycol-based solvent and / or a glycol ether-based solvent, and (E) water (see Patent Document 4 below). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-200627 [Patent Document 2] Japanese Patent Application Laid-Open No. 2007-262258 [Patent Document 3] Japanese Patent Application Laid-Open No. 2003-49193 [Patent Document 4] Japanese Patent Application Publication No. 2019-172743 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the deodorizing composition described in Patent Document 1 has the problem that, depending on the components such as solvents contained, the odor of the deodorizing composition itself may remain on the production line, etc., making it difficult to achieve the desired deodorizing effect. Furthermore, the deodorizing composition described in Patent Document 2 does not address multiple flavor odors, and is not particularly effective against citrus flavor odors. Furthermore, the deodorizing composition described in Patent Document 2 cannot be added simultaneously in the alkaline cleaning step, and therefore cannot be used in one step. On the other hand, the deodorizer described in Patent Document 3 is low-foaming and has a good deodorizing effect, but it does not have sufficient storage stability and there is a risk that the deodorizing effect will be reduced if used in combination with acid or alkali. For this reason, it has been difficult to use it simultaneously in the acid cleaning step or alkali cleaning step of CIP cleaning to shorten the time for the CIP cleaning and deodorizing step. Although the deodorizer described in Patent Document 4 exhibits a deodorizing effect on a variety of flavors, it cannot be said that its deodorizing effect on citrus flavors is sufficient.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a deodorizing composition for food and beverage production lines, which can be used with a variety of flavors, has an excellent deodorizing effect particularly on citrus flavor odors that tend to linger, and effectively removes flavor odors that have adhered to food and beverage production lines even when used simultaneously during CIP cleaning with acid or alkali, and a deodorizing and cleaning method using the same. [Means for solving the problem]

[0008] In order to solve the above problems, the present inventors have conducted extensive research and have found that a specific ether ester type nonionic surfactant, polyoxyalkylene alkyl ether, predeterminedThe present inventors have discovered that a deodorizing composition for food and beverage production lines, which contains an aromatic hydrocarbon, a glycol-based solvent and / or a glycol ether-based solvent, and water, efficiently removes flavors adhering to production equipment and exhibits a uniform deodorizing effect on a wide variety of flavors, particularly common fruit flavors such as apple and banana, as well as citrus fruits such as grapefruit, leading to the completion of the present invention.

[0009] That is, the deodorizing composition for food and beverage production lines of the present invention contains, as component (A), at least one ether ester-type nonionic surfactant selected from polyoxyalkylene fatty acid esters, polyoxyalkylene sorbitan fatty acid esters, polyoxyalkylene sorbitol fatty acid esters, and polyoxyalkylene glycerin fatty acid esters, a polyoxyalkylene alkyl ether as component (B), an aromatic compound as component (C), a glycol-based solvent and / or a glycol ether-based solvent as component (D), and water as component (E), the component (C) contains at least one selected from xylene sulfonic acid or a salt thereof, toluene sulfonic acid or a salt thereof, cumene sulfonic acid or a salt thereof, and benzene sulfonic acid or a salt thereof; The composition is characterized in that it contains the components (A) and (C) in a mass ratio (A) / (C) of 0.1 or more and 10 or less.

[0010] The deodorizing and cleaning method of the present invention is a cleaning method having an acid cleaning step using an acidic cleaning solution and / or an alkaline cleaning step using an alkaline cleaning solution, and is characterized in that when the method has an acid cleaning step but not an alkaline cleaning step, it satisfies the following I), when the method does not have an acid cleaning step but has an alkaline cleaning step, it satisfies the following II), and when the method has both an acid cleaning step and an alkaline cleaning step, it satisfies at least one of the following I) and II). I) The acidic cleaning solution used in the acid cleaning step is an acidic deodorizing cleaning solution containing the deodorizing composition for food and beverage production lines of the present invention described above and an acidic substance and / or an acidic cleaning composition. II) The alkaline cleaning solution used in the alkaline cleaning step is an alkaline deodorizing cleaning solution containing the deodorizing composition for food and beverage production lines of the present invention described above and an alkaline substance and / or alkaline cleaning composition. [Effects of the Invention]

[0011] The deodorizing composition for food and beverage production lines of the present invention (hereinafter sometimes simply referred to as the deodorizing composition) is effective against a variety of flavor odors, but is particularly effective against citrus flavor odors, and can efficiently deodorize and remove flavor odors from previous products that remain on the production line in food and beverage production factories and the like that produce various different products on the same production line. Furthermore, the deodorizing and cleaning method using the deodorizing composition of the present invention can simultaneously achieve deodorization while maintaining good cleaning properties in the acid cleaning step and / or alkaline cleaning step. That is, the deodorizing and cleaning method of the present invention can perform the cleaning step and the deodorizing step in one step, thereby shortening the cleaning time on the production line. DETAILED DESCRIPTION OF THE INVENTION

[0012] In studying the above-mentioned problems, the present inventors attempted to improve the deodorization of citrus flavors, which are particularly difficult to deodorize among flavor odors, and focused on limonene contained in citrus fruits. Limonene is one of the substances contained in citrus fruits, one of the components of citrus scents, and is also used as a fragrance for imparting citrus flavors. Limonene has a monocyclic skeleton with the structure shown in Chemical Formula 1 below. Note that limonene is a chiral compound, and Chemical Formula 1 below shows the d-isomer of limonene (d-limonene), but in understanding the present invention, it is not intended that limonene be limited to d-limonene. [ka]

[0013] After extensive research, the present inventors have completed the present invention based on the technical idea that citrus flavors can be effectively deodorized by using an aromatic compound that has an aromatic ring, similar to limonene, as a component of a deodorizing composition. The present invention will be described in detail below.

[0014] The deodorizing composition for food and beverage production lines contains, as component (A), at least one ether ester-type nonionic surfactant selected from polyoxyalkylene fatty acid esters, polyoxyalkylene sorbitan fatty acid esters, polyoxyalkylene sorbitol fatty acid esters, and polyoxyalkylene glycerin fatty acid esters; as component (B), a polyoxyalkylene alkyl ether; as component (C), an aromatic compound; as component (D), a glycol-based solvent and / or a glycol ether-based solvent; and as component (E), water; and the components (A) and (C) are contained in a mass ratio such that the value of (A) / (C) is 0.1 or more and 10 or less.

[0015] The deodorizing composition of the present invention having such a configuration can deal with a variety of flavor odors, and is particularly effective in deodorizing citrus flavor odors. In food and beverage manufacturing plants and the like that manufacture a variety of different products on the same production line, the composition can efficiently deodorize and remove flavor odors from previous products that remain on the production line. Furthermore, the deodorant composition of the present invention prevents its own odor from remaining on the production line after cleaning, which would reduce the deodorizing effect, and also has excellent storage stability.

[0016] In addition, even when the deodorizing composition of the present invention is used in combination with an acidic or alkaline cleaning agent, it exhibits an excellent deodorizing effect and prevents the cleaning properties of the acidic or alkaline cleaning agent from being reduced. Therefore, the deodorizing composition of the present invention can simultaneously achieve deodorization while maintaining good cleaning properties in the acid cleaning step and / or alkaline cleaning step in the deodorizing cleaning method of the present invention described below.

[0017] Examples of the ether ester-type nonionic surfactant for component (A) include polyoxyalkylene fatty acid esters, polyoxyalkylene sorbitan fatty acid esters, polyoxyalkylene sorbitol fatty acid esters, and polyoxyalkylene glycerin fatty acid esters.

If the HLB value is less than 8, storage stability may be reduced, and if the HLB value exceeds 16, foam suppression may be reduced. In the present invention, HLB is a value determined by Griffin's method. The Griffin's method can be found, for example, in "New Edition Surfactant Handbook" (co-edited by Yoshida, Shindo, Ogaki, and Yamanaka, Kogaku Tosho Co., Ltd., 1996, p. 234).

[0045] Next, the deodorizing and cleaning method of the present invention will be described. The deodorizing and cleaning method of the present invention is a cleaning method having an acid cleaning step using an acidic cleaning solution and / or an alkaline cleaning step using an alkaline cleaning solution. The deodorizing and cleaning method of the present invention is characterized in that it satisfies the following condition I) when it has an acid cleaning step but not an alkaline cleaning step, satisfies the following condition II) when it has no acid cleaning step but an alkaline cleaning step, and satisfies at least one of the following conditions I) and II) when it has both an acid cleaning step and an alkaline cleaning step. I) The acidic cleaning solution used in the acid cleaning step is an acidic deodorizing cleaning solution containing the deodorizing composition for food and beverage production lines of the present invention and an acidic substance and / or an acidic cleaning composition. II) The alkaline cleaning solution used in the alkaline cleaning step is an alkaline deodorizing cleaning solution containing the deodorizing composition for food and beverage production lines of the present invention and an alkaline substance and / or alkaline cleaning composition.

[0046] The deodorizing composition of the present invention exhibits excellent deodorizing effects even when mixed with an acidic or alkaline cleaning agent, and does not impair the cleaning properties of the acidic or alkaline cleaning. Therefore, the deodorizing cleaning method of the present invention can simultaneously achieve deodorization while maintaining good cleaning properties in the acidic cleaning step and / or alkaline cleaning step. In other words, the deodorizing cleaning method of the present invention can perform the cleaning step and deodorizing step in one step, thereby shortening the cleaning time for production lines, parts, etc.

[0047] When an acid washing step and an alkali washing step are included, whether the deodorizing step is performed in one step in the acid washing step or the alkali washing step is not particularly limited, and can be determined, for example, depending on the type of main flavor remaining in the production line after use. For example, by carrying out the acid washing step using the acidic deodorizing detergent solution described in I) above, a wide range of flavors, such as terpene hydrocarbons, esters, higher aliphatic alcohols, aromatic alcohols, higher aliphatic aldehydes, aromatic aldehydes, and lactones, can be effectively deodorized. Furthermore, by carrying out alkaline washing using the alkaline deodorizing detergent solution described in II) above, a wide range of flavors can be effectively deodorized, similar to the acid washing step using the acidic deodorizing detergent solution described in I) above, but flavors such as terpene hydrocarbons and esters can be effectively deodorized. By using an acidic deodorizing detergent solution in the acid washing step and an alkaline deodorizing detergent solution in the alkaline washing step, more complex flavors can be effectively deodorized.

[0048] The acidic deodorizing cleaner solution used in I) above contains the deodorizing composition of the present invention and an acidic substance and / or an acidic cleaner composition. The acidic substance can be appropriately selected from the acidic substances contained in the acidic cleaner used in the acid cleaning process. Examples of the acidic substance include, but are not limited to, one or a combination of two or more acids such as nitric acid, sulfamic acid, methanesulfonic acid, and citric acid. The acidic cleaner composition refers to a composition containing the acidic substance and other substances. The other substances may be selected from one or more known additives that can be added to cleaners, such as surfactants, defoamers, organic solvents, thickeners, and fragrances. In the acid washing step, the acidic substance is preferably diluted to a concentration of about 0.10% by mass or more and 5.0% by mass or less.

[0049] The alkaline deodorizing detergent solution used in II) above contains the deodorizing composition of the present invention and an alkaline substance and / or an alkaline detergent composition. Here, the alkaline substance may be, but is not limited to, one or a combination of two or more alkalis such as sodium hydroxide and potassium hydroxide. The alkaline detergent composition refers to a composition containing substances other than the alkaline substance. The other substances may be, for example, one or more of known additives that can be added to detergents, such as surfactants, defoamers, organic solvents, thickeners, and fragrances. In the alkaline washing step, the alkaline substance is preferably diluted to a concentration of about 0.10% by mass or more and 5.0% by mass or less.

[0050] The deodorizing and cleaning method of the present invention may be either a disassembly cleaning method in which disassembled parts of machinery and equipment in a food and beverage production line are brought into contact with the above-mentioned deodorizing cleaning agent solution to deodorize, or a cleaning-in-place (CIP) method in which the machinery and equipment in a food and beverage production line is not disassembled but is instead brought into contact with the above-mentioned deodorizing cleaning agent solution on the treated surface to deodorize. In either cleaning method, the following may be appropriately selected: Mode A, in which an acid cleaning step using an acidic deodorizing cleaning solution is performed without performing an alkaline cleaning step; Mode B, in which an alkaline cleaning step using an alkaline deodorizing cleaning solution is performed without performing an acid cleaning step; and Mode C, in which both the acid cleaning step and the alkaline cleaning step are performed (in this case, the order of the steps is not limited). In the above-mentioned Mode C, the cleaning agent used in at least one of the acid cleaning step or the alkaline cleaning step may contain the deodorizing cleaning solution of the present invention. In the following description, the acidic deodorizing detergent liquid and the alkaline deodorizing detergent liquid may be collectively referred to as deodorizing detergent liquids as appropriate.

[0051] (Disassembly and cleaning) The disassembly and cleaning can be carried out by any suitable method including a step of contacting the disassembled parts with the deodorizing detergent liquid to clean and deodorize them. For example, a dipping method in which the disassembled parts are dipped in the deodorizing detergent liquid, or a spraying method in which the disassembled parts are sprayed with the deodorizing detergent liquid, can be employed.

[0052] (clean-in-place) The cleaning-in-place method can employ a treatment method including a step of appropriately contacting the odor-removing detergent liquid with the area to be deodorized in the undecomposed food and beverage production line to clean and deodorize it. For example, deodorization can be performed by a circulation treatment method in which the deodorizing detergent liquid is circulated inside an apparatus equipped with an undecomposed food and beverage production line for deodorization, or by a spray treatment method in which the deodorizing detergent liquid is sprayed onto the area to be deodorized of the undecomposed food and beverage production line. In the circulation treatment method, it is preferable to circulate the deodorizing detergent liquid so that the deodorizing detergent liquid comes into sufficient contact with the inside of the tanks or piping in the food and beverage production line and the inside of various equipment, etc. The method for spraying the deodorizing detergent liquid in the above-mentioned spray treatment method is not particularly limited, but a high-pressure washer capable of high-pressure spraying can be preferably used.

[0053] A typical cleaning-in-place (CIP) process involves an alkaline cleaning step, a water rinse step, an acid cleaning step, and a water rinse step, in that order. A water cleaning step may be performed before these steps, and a sterilization step and a water rinse step may be performed after these steps. Depending on the ingredients of the cleaning agent used and the type and condition of the dirt, some of these steps may be omitted, the order may be changed, or the same steps may be repeated.

[0054] In the acid washing step or alkaline washing step, the temperature of the deodorizing detergent liquid is adjusted to a range of preferably 10 to 160°C, more preferably 60 to 160°C, and even more preferably 80 to 140°C. In the injection treatment in the decomposition deodorization step or the circulation or injection treatment in the stationary deodorization step, it is preferable to circulate or inject the diluted solution under pressure of 100 kPa to 550 kPa. A higher deodorizing effect can be obtained by circulating or injecting the diluted solution adjusted to a temperature range of 60 to 160°C, particularly a temperature range of 80 to 140°C, under the above-mentioned pressure.

[0055] In the deodorizing and cleaning method of the present invention, the deodorizing composition can be mixed with an alkaline cleaner used in the alkaline cleaning step of CIP cleaning or an acid cleaner used in the acid cleaning step. This allows the alkaline cleaning step and the deodorizing step, or the acid cleaning step and the deodorizing step, to be performed simultaneously, thereby shortening the deodorizing and cleaning time. When preparing a deodorizing cleaning solution, the deodorizing composition of the present invention may be diluted and mixed with the alkaline cleaner or the acid cleaner, or the deodorizing composition may be mixed undiluted. By simultaneously performing the deodorizing step in the alkaline cleaning step or the acid cleaning step of CIP cleaning in this way, the cleaning and deodorizing time on a food and beverage production line is significantly shortened, allowing for rapid product changeover and significantly improving the production rate for each product. In CIP cleaning, the deodorizing composition of the present invention can be mixed with one or both of an alkaline cleaner and an acid cleaner to perform cleaning and deodorization simultaneously. Even in this case, a separate deodorizing step can be added.

[0056] Although the above description has been given of the case where the deodorizing composition of the present invention is used in combination with an alkaline or acidic cleaning agent in CIP cleaning, the mixture of the deodorizing composition of the present invention with an alkaline or acidic cleaning agent can be used not only in CIP cleaning but also in a method of disassembling machinery and equipment in a food and beverage production line and spraying a treatment solution onto the object to be cleaned or the outer surface of the object to be cleaned with a high-pressure washer, or a method of immersing the object to be cleaned in a treatment solution. In this case, the concentrations of the deodorizing composition, alkaline cleaning agent, and acidic cleaning agent are preferably used at 1 to 10 times the concentrations used in CIP cleaning.

[0057] Furthermore, the above-described deodorizing and cleaning method of the present invention does not limit the method of using the deodorizing composition for food and beverage production lines of the present invention. The deodorizing composition for food and beverage production lines of the present invention may be used when a deodorizing step is carried out alone, independently of an acid cleaning step or an alkali cleaning step. When carrying out a deodorizing process on a food and beverage production line using the deodorizer composition of the present invention, a dilution liquid is typically prepared by diluting the deodorizer composition of the present invention with a dilution solvent such as water, hot water, a non-aqueous solvent, or an aqueous solvent. From the standpoint of economy and safety, it is preferable to use water or hot water as the dilution solvent. The water or hot water referred to here includes ion-exchanged water, distilled water, pure water, soft water, tap water, etc., and the temperature during use is not limited. The temperature of the dilution liquid during dilution is not particularly limited, but is preferably adjusted to a range of 10°C or higher and 85°C or lower, for example. Here, the dilution ratio of the deodorizer composition is not particularly limited and may be adjusted as appropriate. For example, by diluting the deodorizer composition of the present invention so that the content of the deodorizer composition in the diluted solution is 0.10 mass % or more and 10.0 mass % or less, a concentration at which each component contained in the deodorizer composition contributes to deodorization can be ensured, and an excellent deodorizing effect can be sufficiently obtained. [Example]
