It is expressed as XM2/nO・AI 2 O 3・YSiO 2・ZH 2 O.
Here, M represents an ion exchangeable ion, which is usually a monovalent or divalent metal ion, such as sodium, potassium, magnesium, iron, etc., n is the valence of the metal ion, and X is a metal oxide. Y is the coefficient of silica, and Z is the number of crystal water molecules. Such a general formula XM2/nO・
The ion exchange capacity of zeolite expressed as AI 2 O 3・YSiO 2・ZH 2 O is 2.6 meq/g to 11.5 meq/g
It is. Therefore, the antibacterial zeolite 3 converts these ion-exchangeable ions into antibacterial metal ions,
For example, it is substituted with silver, copper, zinc, or the like. From the viewpoint of antibacterial properties, the antibacterial zeolite 3 desirably contains about 0.1 to 15% by weight of these antibacterial metal ions in the zeolite (indicated by weight% on a dry basis at 110°C).

(See "Antibacterial Zeolite" filed on December 4, 1988, claiming priority under Article 42-2, Paragraph 1 of the Patent Law). The reason for adding ammonium ions in this way is to effectively prevent discoloration of antibacterial zeolite 3, and the ammonium ions in antibacterial zeolite 3 are 0.5 to 2.0.
It is preferable to have the weight percentage within the range. Furthermore, from the viewpoint of substantially preventing discoloration of the thermoplastic resin 2, it is preferable that the content of the antibacterial zeolite 3 containing ammonium ions is 0.1 to 3.0% with respect to the thermoplastic resin 2. .

In other words, the antibacterial properties were reconfirmed through antibacterial activity tests as described below, and the sustainability of the antibacterial activity was confirmed by uniformly packing antibacterial zeolite 3 into a glass column with an inner diameter of 22 mm and reducing the volume of the packed bed. 10ml, and add 25~25~25ml of tap water into this column.
Antibacterial Zeolite 3 still retains its antibacterial activity even after 5,000 water passes through it at a flow rate of 30ml/min, and its antibacterial activity can be said to last semi-permanently. In addition, it can withstand heat up to 550℃, and has passed antibacterial metal elution tests for safety.

After use, the sterile grater plate 1 is cleaned of oil, plant residue, etc., and then stored in a drawer or the like again. At this time, since the surface of the sterile grater plate 1 has antibacterial properties, the surface of the sterile grater plate 1 can be kept in a sterile state unless it is particularly dirty with dirt, dust, etc., or if the drawer is not dirty. Since the sterile grater plate 1 is sagging, it is not necessary to wash or sterilize the sterile grater plate 1, and the sterile grater plate 1 can be used as is.

Survival bacteria on the sample pieces were washed out using SCDLP liquid medium (Daigo Nutrient Chemical), and the number of viable bacteria was measured using the washout solution using a pour plate culture method (37°C for 2 days) using a bacterial count measurement medium. This was converted into the number of viable bacteria per sample piece. The same amount of bacterial solution as that sprayed onto the test piece was dispensed into a shear dish, stored at 37°C, and the number of viable bacteria was measured immediately, 24, and 48 hours later.

行なう。[Effects of the invention] As detailed above, the sterile grater plate of the present invention prevents microorganisms attached to the multilayer sheet containing antibacterial zeolite, which is the grater surface.
The food is killed by the bactericidal ions in the antibacterial zeolite, leaving the grating surface sterile, and a thermoplastic resin sheet provides strong support when grating the food.

その抗菌効果が長時間（半永久的）持続する。 Therefore, although the configuration is simple, the grater plate can be kept sterile even if it is stored for a long period of time, making it easy to manage the sanitation of the grater plate and preventing dirt such as dirt and dust. If you store the grater plate so that it does not stick to the grater plate, there is no need to wash and disinfect the grater plate when you use it. Antibacterial substances elute from the antibacterial zeolite like conventional disinfectants. Because it does not evaporate or evaporate, it does not change the taste of food due to its antibacterial properties, nor is it toxic.
Its antibacterial effect lasts for a long time (semi-permanent).
又、抗菌性ゼオライトは、熱に対して強いか
ら、熱による影響を受けにくく、おろし板の製作
時に550℃以上の温度がかからなければ、その抗
菌効果が薄れることがない。 In addition, antibacterial zeolite is resistant to heat, so it is not easily affected by heat, and its antibacterial effect will not fade as long as the grater plate is not exposed to temperatures of 550°C or higher during production.
更に、所定の抗菌力、滅菌力を得るための抗菌

の効果がある。 Furthermore, since the amount of antibacterial zeolite added may be small in order to obtain the desired antibacterial and sterilizing properties, good processability can be maintained without impairing the inherent physical properties of thermoplastic resins, etc. It has the advantage of being able to maintain its economic efficiency as well as being able to do so.
