Description

The present invention relates to a deodorant composition for a food and drink production line used for deodorizing manufacturing equipment and manufacturing equipment such as food and beverage factories, and a deodorizing cleaning method using the deodorant composition.

In a food and beverage manufacturing factory that manufactures foods and beverages, various different products are manufactured on the same manufacturing line, so each time the manufacturing product is switched, it is manufactured so that the previous product remaining in the manufacturing line is not mixed. It is necessary to clean the line. In a food and beverage manufacturing factory, CIP (cleaning in place) cleaning is performed to clean the inside as it is without disassembling the manufacturing equipment and manufacturing equipment. In CIP cleaning, cleaning is performed by circulating the cleaning liquid inside the manufacturing equipment or by spraying the cleaning liquid, but the flavor odor tends to adhere and remain on the packing part (seal part) of the pipe connection part, and the flavor odor. Sufficient cleaning is required to sufficiently remove the shavings, which requires a great deal of labor.
In particular, in recent years, the types of products to be manufactured have increased, the frequency of switching between manufactured products has increased, and it is required to improve the production speed of each product. Deodorizing work is required, which causes a significant decrease in productivity.

There is also a method of disassembling and cleaning the manufacturing equipment instead of CIP cleaning, but it is not realistic to perform disassembly work and assembly work every time the manufactured product is switched, and even if it is disassembled, for example, it is not realistic. It is not easy to completely remove the flavor odor adhering to the packing part by cleaning.

Conventionally, in order to remove the flavor odor adhering to the production line in a food factory, a beverage factory, etc., it is treated with an acidic cleaning agent and / or an alkaline cleaning agent, or after cleaning with an acidic cleaning agent or an alkaline cleaning agent, the following is performed. A method of deodorizing using an oxidizing agent such as sodium chlorite, peracetic acid, percarbonate, or perborate has been adopted, but a sufficient deodorizing effect may not be obtained. Under these circumstances, a technique for further improving the flavor removal efficiency in CIP cleaning has been proposed, and is used for CIP cleaning containing a solvent (A) and a surfactant (B) having an SP value of 6 to 9 at 25 ° C. Deodorant composition (see Patent Document 1 below), (A) a specific nonionic surfactant having an HLB value of 8 to 18, (B) a nonionic surfactant having an HLB value of less than 8, (C) at 25 ° C. Contains a water-soluble solvent having an SP value of more than 9, (D) a deodorant composition for CIP containing water (see Patent Document 2 below), and a specific nonionic surfactant such as a polyoxyalkylene fatty acid ester as a main component. CIP cleaning deodorant composition (see Patent Document 3 below), (A) ether ester type nonionic surfactant, (B) polyoxyalkylene alkyl ether, (C) sorbitan fatty acid ester, (D) glycol solvent and / Or a glycol ether solvent, (E) a deodorant composition for a food and drink production line containing water (see Patent Document 4 below) and the like have been proposed.

However, the deodorant composition described in Patent Document 1 has a problem that it is difficult to obtain a desired deodorizing effect because the odor of the deodorant composition itself remains on the production line or the like depending on the components such as the solvent contained therein. There is.
Further, the deodorant composition described in Patent Document 2 does not correspond to a plurality of flavor odors, and the deodorizing effect is not sufficient particularly for citrus flavor odors. Further, the deodorant composition described in Patent Document 2 cannot be added at the same time in the alkaline cleaning step and performed in one step.
On the other hand, although the deodorant described in Patent Document 3 has a low foaming property and a good deodorizing effect, the storage stability is not sufficient, and the deodorizing effect may be lowered when used in combination with an acid or an alkali. Therefore, it has been difficult to shorten the time required for the CIP cleaning and deodorizing processes by simultaneously using the CIP cleaning in the acid cleaning process and the alkaline cleaning process.
Although the deodorant described in Cited Document 4 exerts a deodorizing effect on various flavors, it cannot be said that the deodorizing effect on citrus flavors is sufficient.

The present invention has been made in view of the above problems, and is capable of dealing with various flavors, exhibits a particularly excellent deodorizing effect on citrus flavor odors in which odors tend to remain, and CIP with acids and alkalis. It is an object of the present invention to provide a deodorant composition for a food and drink production line, and a deodorizing and cleaning method thereof, which effectively removes a flavor odor adhering to the food and drink production line even when used at the same time during cleaning.

As a result of diligent studies, the present inventor has conducted diligent studies to solve the above-mentioned problems, and as a result, a specific ether ester type nonionic surfactant, a polyoxyalkylene alkyl ether, an aromatic hydrocarbon, a glycol solvent and / or a glycol ether solvent, and The water-containing deodorant composition for food and beverage production lines efficiently removes flavors adhering to the production equipment and diversifies the flavors, especially in addition to general fruit flavors such as apple and banana, as well as grapefruit and the like. We have found that it exerts a homogeneous deodorizing effect on citrus fruits, and have completed the present invention.

That is, the deodorant composition for a food and drink production line of the present invention is selected from polyoxyalkylene fatty acid ester, polyoxyalkylene sorbitan fatty acid ester, polyoxyalkylene sorbitol fatty acid ester, and polyoxyalkylene glycerin fatty acid ester as the component (A).

And.

Further, the deodorizing cleaning method of the present invention is a cleaning method having an acid cleaning step using an acidic cleaning agent solution and / or an alkaline cleaning step using an alkaline cleaning agent solution, and has an acid cleaning step and an alkaline cleaning step. If not, the following I) is satisfied, and if the acid cleaning step is not provided and the alkali cleaning step is provided, the following II) is satisfied, and if the acid cleaning step and the alkali cleaning step are provided, the following I) is satisfied. Alternatively, it is characterized by satisfying at least one of the following II).
I) The acidic detergent solution used in the acid cleaning step is an acidic deodorant cleaning agent containing the above-mentioned deodorant composition for a food and drink production line of the present invention and an acidic substance and / or an acidic cleaning agent composition. It is a liquid.
II) The alkaline cleaning agent solution used in the alkaline cleaning step is an alkaline deodorizing cleaning agent containing the above-mentioned deodorizing agent composition for a food and drink production line of the present invention and an alkaline substance and / or an alkaline cleaning agent composition. It is a liquid.

The deodorant composition for a food and drink production line of the present invention (hereinafter, may be simply referred to as a deodorant composition) corresponds to various flavor odors, but particularly has an excellent deodorizing effect on citrus flavor odors. As a result, in a food and beverage manufacturing factory or the like that manufactures various different products on the same production line, it is possible to efficiently deodorize and remove the flavor odor of the product before it adheres and remains on the production line.
In addition, the deodorizing cleaning method using the deodorant composition of the present invention can simultaneously deodorize while maintaining good detergency in the acid cleaning step and / or the alkaline cleaning step. That is, in the deodorizing cleaning method of the present invention, the cleaning step and the deodorizing step can be performed in one step, and the cleaning time of the production line can be shortened.

In the examination of the above-mentioned problems, the present inventor tried to improve the deodorization of citrus flavors, which are particularly difficult to deodorize among the flavor odors, and focused on limonene contained in the citrus fruits. Limonene is one of the substances contained in citrus fruits, one of the constituents of citrus scents, and is also used as a fragrance for imparting citrus flavors. Limonene has a monocyclic skeleton showing the structure shown in Chemical formula 1 below. Limonene is a chiral compound, and although limonene is shown as a d-form (d-limonene) in Chemical formula 1 below, it is not intended to limit limonene to d-limonene in order to understand the present invention.

The deodorant composition of the present invention having such a structure can deal with various flavor odors, exerts an excellent deodorizing effect particularly on citrus flavor odors, and produces various different products on the same production line. It is possible to efficiently deodorize and remove the flavor odor of the product before it adheres to and remains on the production line in the food and beverage manufacturing factory or the like where the product is manufactured.
Further, the deodorant composition of the present invention is prevented from having its own odor remaining on the production line or the like after cleaning to reduce the deodorizing effect, and is also excellent in storage stability.
