JP5048277B2 - Deodorant composition for CIP and method of using the same - Google Patents

Description

  The present invention relates to a deodorant composition for CIP that efficiently removes flavors adhering to production facilities for various beverages or foods (referred to herein as “food and beverage products”), particularly flavors adhering to packings, and the like. Related to the deodorizing method.

  In recent years, with the diversification of tastes, many beverages and foods using various flavors have been produced.

  However, since this type of food and drink has a flavor odor, the flavor odor adheres strongly to this manufacturing equipment, particularly packing, and the like, and the deodorization of the flavor odor is a major problem. “Manufacturing equipment” as used herein refers to a tank including a tank for manufacturing food and drink, a raw material tank and a filling machine, and pipes, valves and the like for connecting them.

  In particular, in food factories and beverage factories, CIP cleaning (Cleaning In Place) that cleans the interior without disassembling the manufacturing equipment is often used, but in this CIP cleaning, there is a problem of deodorizing flavor odors. It has become.

  In general, CIP cleaning methods include 1) product discharge (hot water cleaning), 2) chemical cleaning (acid or alkali), 3) hot water cleaning (intermediate rinsing), 4) chemical cleaning (alkali or acid), 5) Hot water washing (intermediate rinsing), 6) chemical washing (bactericidal agent: sodium hypochlorite, peracetic acid, iodine, surfactant, enzyme, etc.), 7) hot water washing (final rinsing). Depending on the type and state of dirt, some of these operations may be omitted, or the same operation may be repeated. The alkali cleaning step, acid cleaning step, and sterilization step are performed at 10 to 90 ° C. for 10 to 60 minutes, generally 20 to 40 minutes, depending on the quality and amount of dirt and the scale of various facilities.

  Conventional deodorization techniques for flavor odors include a method of combining an acid cleaning step and an alkali cleaning step using an acidic cleaning agent and / or an alkaline cleaning agent, a method of repeating it, or a method of deodorizing and cleaning by these methods. Thereafter, a method of performing deodorizing treatment by circulating contact with an oxidizing agent such as sodium hypochlorite, peracetic acid, percarbonate, tea extract and the like is employed. However, even if such a cleaning method or deodorizing treatment is performed, a sufficient deodorizing effect on the flavor odor is not obtained.

  JP 2003-49193 A proposes a deodorant composition for CIP cleaning containing a specific nonionic surfactant such as polyoxyalkylene fatty acid ester as a main component. Although there is little damage and it is a low bubble, the problem with respect to flavor odor has not yet been solved (see Patent Document 1).

  In JP-A-2005-206794, 0.005 to 30.0% by weight of one or more selected from the group of fatty acids, ether carboxylic acids, diglycerides or triglycerides and fatty acid esters represented by a specific general formula Alternatively, it contains 0.01% by weight or more of an inorganic acid and / or organic acid, and further contains a solubilizer of 0.005 to 30.0% by weight (all in terms of pure content) as required. A CIP cleaner composed of CIP cleaning that efficiently removes flavors attached to manufacturing facilities such as food and beverages, especially those attached to packing, etc., and has low foaming properties, and can perform both acid cleaning and deodorization processes in one step. An agent composition and a cleaning method using the same are disclosed (see Patent Document 2).

  Japanese Patent Laid-Open No. 2005-200267 includes a solvent A having a predetermined SP value and a surfactant B such as a nonionic surfactant, and can effectively remove residual flavor in CIP (fixed cleaning) cleaning. Later, a cleaning composition for CIP in which almost no solvent odor remains is disclosed (see Patent Document 3). More specifically, the cleaning medium 1 containing a solvent A having a SP value of 6 to 9 at 25 ° C. such as a hydrocarbon compound having 5 to 24 carbon atoms and a surfactant B such as a nonionic surfactant is to be cleaned. The cleaning medium 2 containing the surfactant B and having the concentration of the solvent A of less than 0.5% by weight is brought into contact with the object to be cleaned. The solvent A is preferably an aliphatic hydrocarbon having 10 to 14 carbon atoms, and examples include decane, isodecane, undecane, isoundecane, dodecane, isododecane, tridecane, isotridecane, tetradecane, isotetradecane, C12-α-olefin, and the like. It has been. Further, it is described that the surfactant B is preferably a nonionic surfactant, particularly a polyoxyalkylene alkyl ether, preferably having an HLB value of 3 or more and less than 8 according to the Griffin calculation formula.

JP-A-2005-314580 contains at least one nonionic surfactant selected from alkyl polyglycosides, alkyl glyceryl ethers, and polyoxyalkylene alkyl amines, and efficiently leaves residual flavor in CIP (fixed cleaning) cleaning. Has been disclosed, and a cleaning composition for CIP is disclosed in which a solvent odor hardly remains after cleaning (see Patent Document 4).
Therefore, even if the CIP deodorant composition has a high deodorizing effect on flavor odor, depending on components such as the solvent constituting the CIP deodorant composition, the odor of the CIP deodorant composition itself (hereinafter referred to as “deodorization”). Deodorant by removing the remaining deodorant odor due to other washing steps or rinsing, etc. Since the flavor odor masked by the agent odor may appear, it is desired that the CIP deodorant composition itself has no odor.

From the results of Tables 1 to 8, all of the CIP deodorant compositions of Examples 1 to 25 were evaluated for deodorization, persistence, material influence, storage stability, detergency, and low foamability test. It can be seen that the item has excellent performance. Moreover, even if it is a case where it uses together with an alkaline CIP cleaning composition and an acidic CIP cleaning composition, it turns out that it has the outstanding performance in various evaluation items.
