Description

  The present invention relates to a cleaning composition for foods and a cleaning method for foods, which have high cleaning performance and can be used for food without rinsing when cleaning various foods such as fruits, vegetables, and seafood. About.

There are beer factories all over the world such as Germany, Japan, Canada, etc., but sufficient and simple cleaning is required when the barley, the raw material, is received.
In the first place, the surface of various foods such as fruits, vegetables, and seafood is soiled with solids such as soil, sand, and wood, oil such as wax, and agricultural chemicals, and is contaminated with insects and microorganisms. In many cases, in order to remove these by washing, a method of washing by immersing in a washing liquid (water tank) to which an anionic surfactant such as sodium dodecylbenzenesulfonate (DSS) is added has been adopted. .
However, although the DDS etc. have excellent cleaning performance, if the rinsing is insufficient, the DDS etc. will adhere to the surface of foods rather than removing the dirt (things) adhering to the surface. Since the possibility of becoming a problem in terms of the surface becomes strong, sufficient rinsing is required.

On the other hand, for example, sucrose fatty acid esters having high HLB values are approved as food additives and food emulsifiers, so even if they are not sufficiently rinsed and remain on the surface of foods, hygiene It is less likely to cause problems and is highly safe. Therefore, a detergent composition mainly composed of sucrose fatty acid ester or the like has been proposed (for example, Patent Document 1).
JP 50-39707 A

However, since the cleaning agent of Patent Document 1 and the like does not have sufficient cleaning performance, there is a fatal problem that even if foods are immersed in the cleaning liquid for a long time, the original cleaning cannot be performed satisfactorily. there were.
Therefore, an object of the present invention is to propose a food cleaning composition that has a sufficiently high cleaning performance and can be used for foods even if rinsing is not sufficient or rinsing is not performed.

  The present invention has been proposed in view of the above, sucrose fatty acid ester 8 to 10% by weight, sodium malate 0.2 to 0.5% by weight, starch syrup 3 to 5% by weight, and baking soda 3 to 5% by weight. % And water, it is related with the cleaning composition for foodstuffs characterized by the above-mentioned.

  In the food cleaning composition, it is desirable to add 0 to 2% by weight of a fragrance and 5 to 10% by weight of ethanol.

  The present invention also proposes a method for cleaning foods characterized in that the surface of the foods is brought into contact with the food cleaning composition and used as it is for food.

The cleaning composition for food of the present invention has high cleaning performance when washing various foods such as fruits, vegetables, and seafood, and can be used for food without rinsing.
Therefore, for example, it can be used for washing barley stocked as a raw material in a beer factory, and the food detergent composition of the present invention is accommodated in a large aquarium, and a large volume of barley is placed therein and immersed therein. Therefore, it can be cleaned sufficiently and easily. And it can use for a subsequent process, without performing rinse etc.
Furthermore, when washing small-sized foods such as barley and soybeans, the fact that no subsequent rinsing is required means that the use of enormous amounts of water used for rinsing is not necessary. This is a big advantage including reduction.
In addition, it can be used for cleaning just before shipment of various foods, so that the freshness of the foods can be prevented from being reduced, the unique odor emitted by the foods can be suppressed, or the damage during transportation can be suppressed. it can.

  Moreover, by adding a fragrance | flavor and ethanol, in addition to the said effect, the effect of odor extinction and the improvement of a preservability can be aimed at.

  Furthermore, the method for cleaning foods of the present invention is particularly suitable for cleaning small diameter foods.
