Description

Technical Field

[0001] The present invention relates to a deodorant composition for food and beverage production lines used for deodorizing production equipment and production machinery in food and beverage factories.

[0002] In food and beverage manufacturing factories that produce food and beverages, since different types of products are manufactured on the same production line, it is necessary to clean the production line every time the manufactured product is switched so that the previous product remaining in the production line does not mix in. In food and beverage manufacturing factories, CIP (Cleaning in Place) cleaning, which cleans the interior of production equipment and machinery without disassembling them, is performed. In CIP cleaning, cleaning is performed by circulating a cleaning solution inside production equipment or spraying the cleaning solution. However, flavor odor tends to adhere and remain in the packing parts (sealing parts) of pipe connections, and sufficient cleaning is required to sufficiently remove the flavor odor, which requires a great deal of labor. In particular, in recent years, the types of products manufactured have increased, the frequency of switching manufactured products has also increased, and improvement in production speed for each product is required. However, in order to sufficiently remove diversifying flavor odors, long-time cleaning and deodorizing work is required, which is a cause of significantly reducing productivity.

[0003] There is also a method of disassembling and cleaning production equipment instead of CIP cleaning, but performing disassembly and assembly work every time the manufactured product is switched requires a large amount of labor and is not practical. In addition, even if disassembly is performed, it is not easy to completely remove the flavor odor adhering to packing parts and the like by cleaning.

[0004] Conventionally, in order to remove flavor odors adhering to production lines in food and beverage factories, methods have been employed such as treating with acidic and / or alkaline cleaning agents, or cleaning with acidic or alkaline cleaning agents followed by deodorization using oxidizing agents such as sodium hypochlorite, peracetic acid, percarbonate, and perborate. However, sufficient deodorization effects are not always obtained. Given these circumstances, CIP cleaning deodorizer compositions have been proposed that contain a solvent (A) and a surfactant (B) with an SP value of 6 to 9 at 25°C (Patent Document 1), a CIP cleaning deodorizer composition containing (A) cyclodextrin, (B) ether carboxylic acid or its alkali salt, (C) nonionic surfactant, (D) solubilizer and (E) water (see Patent Document 2), and a CIP cleaning deodorizer composition containing a cyclodextrin component in which three types of cyclodextrins are used in combination as component (A) (see Patent Document 3). [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2005-200627 [Patent Document 2] Japanese Patent Publication No. 2007-77290 [Patent Document 3] Patent No. 5822337 specification [Overview of the project] [Problems that the invention aims to solve]

[0006] Although the deodorizing agent composition in Patent Document 1 has good deodorizing properties, it contains a surfactant, which causes foaming during CIP cleaning and wastewater discharge, impairing rinsing performance and potentially having adverse effects on the environment and ecosystems. The deodorizing agent composition in Patent Document 2 has excellent deodorizing properties and low foaming properties, but when used in an alkaline cleaning process, its deodorizing properties decrease, making it impossible to perform CIP cleaning in one stop. The deodorizing agent composition in Patent Document 3 has excellent deodorizing properties and can be added simultaneously in an acid or alkaline cleaning process to perform deodorization in one stop, but it causes excessive foaming in the factory wastewater after CIP cleaning, which may lead to a decrease in wastewater treatment capacity and environmental pollution.

[0007] The present invention has been made in view of the above problems, and aims to provide a deodorizing agent composition for food and beverage manufacturing lines that can be added as a deodorizer in the presence of a detergent agent during an acid or alkaline cleaning process, and further exhibits low foaming and excellent rinsing properties during CIP cleaning.

(3) The deodorizing agent composition for food and beverage manufacturing lines according to (1), wherein the mass ratio (A) / (B) of the mass of component (A) to the mass of component (B) is 1.0 or more and 150 or less.

[0039] Next, the deodorizing and cleaning method of the present invention will be described. The deodorizing and cleaning method of the present invention is characterized in that (I) a method of immersion in a diluted deodorizing agent solution, (II) a method of adding a deodorizing step using a diluted deodorizing agent solution to a normal CIP cleaning step, and (III) a cleaning method in which both the acid or alkaline cleaning step and the deodorizing step are performed in one step when using a CIP deodorizing agent composition and an acid cleaning step using an acidic cleaning agent solution and / or an alkaline cleaning step using an alkaline cleaning agent solution. The deodorizing and cleaning method of the present invention is characterized in that if it has an acid cleaning step and does not have an alkaline cleaning step, it satisfies (III)-1 below, if it does not have an acid cleaning step and has an alkaline cleaning step, it satisfies (III)-2 below, and if it has both an acid cleaning step and an alkaline cleaning step, it satisfies at least one of (III)-1 or (III)-2 below. (III)-1: The acidic cleaning solution used in the acid cleaning step is an acidic deodorizing cleaning solution containing the deodorizing agent composition for food and beverage manufacturing lines of the present invention and an acidic substance and / or an acidic cleaning agent composition. (III)-2: The alkaline cleaning solution used in the alkaline cleaning step is an alkaline deodorizing cleaning solution comprising the deodorizing agent composition for food and beverage manufacturing lines of the present invention and an alkaline substance and / or the alkaline cleaning agent composition.

[0040] When preparing the deodorizing cleaning solution, the deodorizing composition of the present invention may be diluted and mixed with the alkaline cleaning process or the acid cleaning process, or it may be mixed without dilution. By performing the deodorization process simultaneously with the alkaline cleaning process or the acid cleaning process in CIP cleaning in this way, the time required for cleaning and deodorizing the food and beverage manufacturing line is significantly reduced, enabling quick changeover of manufactured products and significantly improving the production speed for each product. In CIP cleaning, the deodorizing composition for food and beverage manufacturing lines of the present invention can be used in combination with one or both of an alkaline cleaning agent or an acid cleaning agent to perform cleaning and deodorization simultaneously, but even in this case, a separate deodorization process may be provided.

[0041] The deodorizing agent composition of the present invention exhibits excellent deodorizing effects even when mixed with an acidic or alkaline cleaning agent, without reducing the cleaning performance of the acid or alkaline cleaning. Therefore, the deodorizing cleaning method of the present invention can deodorize while maintaining good cleaning performance in the acid cleaning step and / or alkaline cleaning step. In other words, the deodorizing cleaning method of the present invention allows the cleaning step and deodorizing step to be performed in one step, making it possible to shorten the cleaning time for manufacturing lines and parts.

[0042] When there are acid cleaning and alkaline cleaning steps, there is no particular limitation on whether the deodorization step is performed in one step during the acid cleaning or alkaline cleaning step, and can be determined, for example, by the type of main flavor remaining in the production line after use. For example, by performing an acid cleaning process using the acidic deodorizing cleaning agent solution described in (III)-1 above, a wide range of flavors such as terpene hydrocarbons, esters, aliphatic higher alcohols, aromatic alcohols, aliphatic higher aldehydes, aromatic aldehydes, and lactones can be effectively deodorized. Furthermore, by performing alkaline cleaning using the alkaline deodorizing cleaning agent solution described in (III)-2 above, a wide range of flavors can be effectively deodorized in the same way as the acid cleaning process using the acidic deodorizing cleaning agent solution described in (III)-1 above, but flavors such as terpene hydrocarbons and esters can be particularly effectively deodorized. By using an acidic deodorizing cleaning agent solution in the acid cleaning process and an alkaline deodorizing cleaning agent solution in the alkaline cleaning process, more complex flavors can be effectively deodorized.

[0043] The acidic deodorizing cleaning agent liquid used in (III)-1 above comprises the deodorizing agent composition of the present invention and an acidic substance and / or an acidic cleaning agent composition. Here, the acidic substance can be appropriately selected from acidic substances contained in acidic cleaning agents used in the acid cleaning process. For example, the acidic substance can be one or more combinations of acids such as nitric acid, sulfamic acid, methanesulfonic acid, and citric acid, but is not limited to these. The acidic cleaning agent composition means a composition containing the acidic substance and other substances. As the other substances, for example, one or more known additives that can be added to cleaning agents such as surfactants, defoamers, organic solvents, thickeners, and fragrances may be selected. In the acid washing process, the acidic substance mentioned above should preferably be used after being diluted to a concentration of approximately 0.10% by mass or more and 5.0% by mass or less. The pH of the cleaning solution in the acidic cleaning process is 0.1 or higher and 5 or lower, preferably 0.5 or higher and 3 or lower.

[0044] The alkaline deodorizing cleaning agent liquid used in (III)-2 above comprises the deodorizing agent composition of the present invention and an alkaline substance and / or an alkaline cleaning agent composition. Here, the alkaline substance may be one or more alkalis such as sodium hydroxide and potassium hydroxide, but is not limited to these. The alkaline cleaning agent composition means a composition containing the alkaline substance and other substances. As the other substances, one or more known additives that can be added to cleaning agents, such as surfactants, defoamers, organic solvents, thickeners, and fragrances, may be selected. In the alkaline cleaning process, the alkaline substance mentioned above should be used after being diluted to a concentration of approximately 0.10% by mass or more and 5.0% by mass or less. The pH of the cleaning solution in the alkaline cleaning process is 10 or higher and 13.5 or lower, preferably 12 or higher and 13.2 or lower.

[0045] (Disassembly and cleaning) The above disassembly and cleaning can employ an appropriate treatment method that includes a step of contacting the disassembled parts with the above-mentioned deodorizing cleaning solution to clean and deodorize them. For example, an immersion treatment method in which the disassembled parts are immersed in the above-mentioned deodorizing cleaning agent solution, or a spray treatment method in which the above-mentioned deodorizing cleaning agent solution is sprayed onto the disassembled parts, can be employed.

[0046] (CIP cleaning) The above-described CIP cleaning method can employ a treatment method that includes a step of appropriately contacting the deodorizing cleaning solution with the deodorizing cleaning agent solution to clean and deodorize the deodorizing treatment area of ​​an undecomposed food and beverage manufacturing line. For example, deodorization can be performed by a circulation treatment method in which the deodorizing cleaning agent liquid is circulated inside a device equipped with an undecomposed food and beverage manufacturing line, or by a spray treatment method in which the deodorizing cleaning agent liquid is sprayed onto the area to be deodorized in the undecomposed food and beverage manufacturing line. In the circulation treatment method, it is preferable to circulate the deodorizing cleaning agent liquid so that it comes into sufficient contact with the inside of tanks or pipes and the inside of various equipment in the food and beverage manufacturing line. Furthermore, the method of spraying the deodorizing cleaning agent liquid in the above-described spraying method is not particularly limited, but a high-pressure washer or the like that which enables high-pressure spraying can preferably be used.

[0047] Typical CIP cleaning involves performing alkaline cleaning, rinsing with water, acid cleaning, and rinsing with water in that order. In addition, a water rinsing step may be performed as a preceding step, and a sterilization step and rinsing step may be performed as subsequent steps. Depending on the composition of the cleaning agent used and the type and condition of the dirt, some steps may be omitted, the order may be changed, or the same steps may be repeated.

[0048] In the acid cleaning or alkaline cleaning process, the deodorizing cleaning solution is preferably adjusted to a temperature in the range of 10 to 160°C, more preferably 50 to 150°C, and even more preferably 80 to 140°C. Furthermore, in the decomposition deodorization process, the spray treatment, or the stationary deodorization process, the circulation or spray treatment is preferably carried out under a pressure of 100 kPa to 550 kPa. A higher deodorizing effect can be obtained by treating the diluted solution, which has been adjusted to a temperature range of 60 to 160°C, particularly 80 to 140°C, by circulating or spraying it under the aforementioned pressure.

[0049] The above description focused on the use of the deodorizing agent composition of the present invention mixed with an alkaline cleaning agent or an acid cleaning agent in CIP cleaning. However, the mixture of the deodorizing agent composition of the present invention and an alkaline cleaning agent or an acid cleaning agent can be used not only in CIP cleaning, but also in methods of disassembling machinery and equipment in food and beverage manufacturing lines and treating them by spraying the treatment solution onto the object to be cleaned or the outside of the object to be cleaned with a high-pressure washer, or by immersing the object to be cleaned with the treatment solution. In this case, it is preferable to use concentrations of the deodorizing agent composition, alkaline cleaning agent, and acid cleaning agent that are 1 to 10 times the concentrations used in CIP cleaning.

[0050] Furthermore, the deodorizing and cleaning method of the present invention described above does not limit the method of use of the deodorizing agent composition for food and beverage manufacturing lines of the present invention. The deodorizing agent composition for food and beverage manufacturing lines of the present invention may be used in a deodorizing process alone, independently of an acid cleaning process or an alkaline cleaning process. To perform a deodorization process on a food and beverage manufacturing line using the deodorizing agent composition of the present invention, a diluted solution is typically used, which is obtained by diluting the deodorizing agent composition of the present invention with a diluent such as water, hot water, a non-aqueous solvent, or an aqueous solvent. From the viewpoint of economy or safety, it is preferable to use water or hot water as the diluent. The water or hot water referred to here is ion-exchanged water, distilled water, pure water, soft water, tap water, etc., and the temperature at the time of use is not limited. The temperature of the diluted solution at the time of dilution is not particularly limited, but it is preferable, for example, to be adjusted to a range of 10°C or higher and 85°C or lower. The dilution ratio of the deodorant composition is not particularly limited and may be adjusted as appropriate. For example, by diluting the deodorant composition of the present invention so that its content in the diluted solution is 0.10% by mass or more and 10.0% by mass or less, a concentration is ensured in which each component in the deodorant composition contributes to deodorization, and an excellent deodorizing effect can be fully obtained.

[0051] The deodorizing agent composition of the present invention, after deodorization treatment, is usually sent as wastewater to a treatment tank called an aeration tank, where it is mixed with microorganisms. In the aeration tank, air is actively blown in to activate the activity of the microorganisms, which tends to cause foaming. Foaming affects the efficiency of the treatment equipment and is one of the reasons why it cannot perform to its full potential. Therefore, it is required that the composition not foam even during wastewater treatment. [Examples]

The components of the deodorant compositions for food and beverage manufacturing lines used in the examples and comparative examples are shown in Tables 1 to 4 below. The numerical values ​​for the blending amounts shown in Tables 1 to 5 below represent the percentage (mass) of the pure content of each component relative to the deodorant composition for food and beverage manufacturing lines, and "residue" indicating the water content represents the blending amount adjusted so that the total amount of the final prepared deodorant composition for food and beverage manufacturing lines is 100% by mass. The deodorant compositions for food and beverage manufacturing lines were used to perform the measurements and evaluations described later. The measurement results and evaluation results are also shown in Tables 1 to 5 below.
