Description

Hygiene management method for food processing equipment or utensils

The present invention relates to a method for hygiene management of food processing equipment or cooking utensils.

Background Art Kitchen knives used in restaurant kitchens, chopping boards, cooking utensils such as colander, appliances that directly contact food, such as equipment or facilities for producing or processing foods and beverages used in food factories, beverage factories, etc. In order to maintain the level of hygiene, the equipment or facilities produce foods and beverages every day, and then the used equipment, equipment or facilities are cleaned.

These devices, equipment or facilities have various hard surface shapes, such as small gaps, scratches, and complex shapes that are out of reach. When cleaning them, there are places where mechanical force such as sponges and brushes are not fully applied. In such places, dirt that cannot be removed and microorganisms that cannot be removed or cannot be killed easily remain. For this reason, the remaining microorganisms may proliferate again and become unsanitary.

After washing instruments, equipment or facilities, sodium hypochlorite is often used to sterilize microorganisms that could not be removed by washing. However, when using sodium hypochlorite, there is a concern that the chlorine odor derived from sodium hypochlorite may be transferred from the appliance, equipment or equipment to the food, so after using sodium hypochlorite, In order to remove sodium hypochlorite, it is essential to thoroughly rinse the equipment, equipment or equipment. While sodium hypochlorite is in contact with equipment, equipment or equipment, a bactericidal effect is obtained, but the effect is temporary. Therefore, after removing sodium hypochlorite by rinsing the instrument, device or equipment, the bactericidal effect of sodium hypochlorite does not reach the instrument, device or equipment at all. Therefore, when sodium hypochlorite is used, surviving microorganisms may re-grow and result in an unsanitary state with a high number of bacteria.

On the other hand, proposals have been made that suggest not a temporary effect but a continuous sterilization, sterilization or bacteriostasis. For example, in Japanese Patent Application Laid-Open Nos. 4-180303 and 2002-322009, a disinfectant composition using polylysine and protamine and having improved bacteriostatic, bactericidal or bacteriostatic effects has been proposed. . US-A 2005/0049181 discloses a biofilm inhibitor composition comprising polylysine or protamine.
