Description

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

Food and beverage manufacturing factories that manufacture foods and beverages manufacture different products on the same production 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. At food and beverage manufacturing factories, cleaning liquid is circulated inside as it is without disassembling the manufacturing equipment and equipment, and CIP (cleaning in place) cleaning is performed by spraying the cleaning liquid for cleaning. However, the flavor odor tends to adhere and remain on the packing portion (seal portion) of the pipe connecting portion, 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 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.

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, and perborate has been adopted, but a sufficient deodorizing effect cannot be obtained and at the same time, depending on the usage conditions. Damage to manufacturing equipment, etc. may occur. 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 (Patent Document 1), (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) an SP value at 25 ° C. For CIP cleaning containing a specific nonionic surfactant such as a water-soluble solvent having a concentration of 9 or more, (D) water (Patent Document 2), and a specific nonionic surfactant as a main component. Deodorant compositions (Patent Document 3) and the like have been proposed.

However, the deodorant 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 depending on the components such as the solvent contained therein. Further, although the deodorant described in Patent Document 2 is less affected by damage to manufacturing equipment and swelling and deterioration of piping packing, etc., it cannot be added at the same time in the alkaline cleaning process and performed in one step. .. Furthermore, since sufficient deodorizing properties are not exhibited for flavors such as apple, grapefruit, and banana, in factories that manufacture many products with different flavors, the ingredients are blended so as to correspond to different flavors for each product. There was a complicated problem that it was necessary to prepare a deodorant having an adjusted type and ratio of the above. On the other hand, the deodorant described in Patent Document 3 has less damage to the manufacturing equipment, has low foaming properties, and has a good deodorizing effect, but has insufficient storage stability, and the deodorizing effect is reduced when used in combination with an acid or an alkali. Therefore, it is difficult to shorten the CIP cleaning and deodorizing process times by using them simultaneously in the acid cleaning process and the alkaline cleaning process of CIP cleaning.

The present invention has been made in view of the above problems, and exhibits a uniform deodorizing effect even for many different flavor odors, and even when used simultaneously during CIP cleaning with an acid or an alkali, it can be used in a food and beverage production line. It is an object of the present invention to provide a deodorant composition for a food and drink production line, which effectively removes the attached flavor odor and exerts a stronger deodorizing effect, and a deodorizing cleaning method thereof.

As a result of diligent studies to solve the above problems, the present inventors have conducted diligent studies on specific ether ester-type nonionic surfactants, polyoxyalkylene alkyl ethers, sorbitan fatty acid esters, glycol-based solvents and / or glycol ether-based solvents, and water. The deodorant composition for food and beverage production lines containing and efficiently removes flavors adhering to the production equipment, and as a diversifying flavor, particularly uniform deodorization for flavors such as apple, grapefruit, and banana.
