がある。[Prior Art and its Problems] Many kinds of bacteria are present on the surface of fish bodies, carps, digestive organs, and the like. Therefore, even if the caught fish is prevented from being contaminated and stored, its freshness is lowered as a result of the invasion of many bacteria through blood vessels and skin into the muscles. Such a decrease in the freshness of fish is due to the fact that fish meat generally has a high water content and the muscle tissue is soft, so that it is susceptible to trauma,
Bacteria from the outside are easy to invade, and the caught fish are distributed as they are without extracting the internal organs, and the dismantling process is carried out at the retail store or the home at the end, which further promotes. Further, in fish, the cellular tissue is decomposed by the enzyme action of the living body, self-digestion occurs, and rot progresses. That is, the fish that is caught undergoes post-rigor rigor, after which its meat quality gradually becomes softer and its cellular tissue changes from protein to amino acid. In this way, seafood is prone to decay,
There was a problem that the preservation of raw food with high freshness was limited to a very few days. This decay progresses not only in seafood, but also in livestock foods such as beef, pork, and poultry, fruits,
This is a problem common to all fresh food products such as vegetables. Further, there is a problem of preventing ammonia, sulfur-based substances, raw habits of seafood and the like due to decay of these seafood. On the other hand, although various materials such as paper and wood are used as packaging materials for perishable foods, all of them are merely packaging, and none of these packaging materials have anti-corrosion performance. As a countermeasure, as disclosed in JP-A-61-41400, an inorganic mineral powder of any one of silicon oxide, alumina, ferric oxide, calcium oxide, titanium oxide, magnesium oxide, potassium oxide, and sodium oxide is used. Proposals have been made regarding inorganic mineral powder deodorizing paper contained in the fiber structure of paper. Although it is very effective for preserving and absorbing odor, it has a major drawback. That is, since it is an inorganic mineral powder deodorizing paper, it is extremely brittle that it breaks or breaks when packaging items, and the deodorizing effect and antiseptic effect are not useful for actual use, and there is a lot of oxidation. There are various drawbacks that present the object but not all minerals are effective.

The publication describes the use of aluminum hydroxide in adsorbent sheets. Similar to aluminum hydroxide, when aluminum orthophosphate, which is a fine powder adsorbent, is molded into paper and used, the surface is sized with a sizing agent such as starch or a water-soluble polymer.

%, Aluminum hydroxide 60-85% by weight, on both sides of the base paper, a high-polymer synthetic paste prepared by mixing polyacrylic ester and starch or polyacrylamide in a mixing ratio of 30-70: 70-30 is used. 3 to 5% by dry weight of the above is applied to the deodorizing paper containing aluminum hydroxide.

よりも、結果として吸着範囲が拡大される。According to the present invention, as described above, in the structure composed of pulp and aluminum hydroxide, which are the fiber structure of paper, by adding aluminum hydroxide into a powder form, stability is added, and further, with a large surface area of this deodorizing paper. , The ability to absorb bad odors and water is improved. For example, when fresh fish is wrapped and stored in a paper containing aluminum hydroxide powder, the paper has a physically wide adsorption surface due to the aluminum hydroxide powder contained in the fibrous structure of the paper. As a result, the affinity between elements of the aluminum hydroxide powder acts, and as a result, the adsorption range is expanded as compared with the conventional adsorbents such as activated carbon and silica gel.

In addition, aluminum hydroxide reduces the growth of bacteria existing in fresh fish by adsorption of water, and prevents the cell tissue from changing from protein to amine acid. As described above, the deodorizing paper containing the aluminum hydroxide powder of the present invention has an excellent antiseptic action.

止し、容易に魚介類等を包装することができる。Deodorizing paper containing the aluminum hydroxide powder of the present invention,
For example, it can be manufactured as follows. That is, a papermaking process consisting of a pulping process of raw pulp, a selection process, a dehydration process, a bleaching process, a preparation process for hydrating and swelling fibers to a proper length, and a papermaking process for winding up a paper machine 60 to 85% by weight of aluminum hydroxide in 15 to 40% by weight of pulp, which is a liquid stock made by the above-mentioned preparation process
The powder is added and mixed, and then papermaking is performed in the papermaking process to produce paper. In this papermaking, when a high molecular synthetic paste such as polyacrylic acid ester is used, the polyacrylic acid ester alone is insufficient in water retention, and continuous production cannot be performed by a size press or the like. Therefore, by mixing starch and high molecular weight polyacrylamide as a paste with polyacrylic acid ester, the deodorizing paper according to the present invention can obtain water retention and flexibility. Here, in order to obtain a mixed solution of polyacrylamide and polyacrylic acid ester, as an example,
It is advisable to mix them by 50%, or mix them in a ratio of about 30:70, or even about 70:30. When the coating solution is applied using the mixed solution thus blended, and the mixed solution has a content of 3 to 5% of the whole, the pulp and aluminum hydroxide are well combined to form a sheet. In addition, it is possible to prevent the brittle state from being torn or broken and improve the deodorizing power of the finally manufactured paper. The drawing is a schematic enlarged sectional view of the aluminum hydroxide deodorizing paper manufactured as described above. As shown in the drawing, the aluminum hydroxide powder 3 is contained in the fiber structure 2 of the aluminum hydroxide deodorizing paper 1. The surface of the aluminum hydroxide deodorant paper 1 is coated with a high molecular synthetic paste 4 and impregnated into the fiber structure 2 of the aluminum hydroxide deodorant paper 1 to prevent the aluminum hydroxide deodorant paper from becoming brittle and easy. It is possible to package seafood and the like.

補強材としての効果を発揮することができる。[Example] A mixed powder of 20% by weight of pulp and 80% by weight of aluminum hydroxide was added and papermaking was carried out to produce 120 g / m 2 of aluminum hydroxide powder deodorizing paper of the present invention. On both sides of this aluminum hydroxide deodorizing paper, 5 g / m 2 of a mixed solution of polyacrylamide 50% and polyacrylic acid ester 50% was applied, and the fiber structure of the deodorizing paper containing aluminum hydroxide powder was impregnated with the pulp. Enhances the adhesion effect with aluminum hydroxide, prevents embrittlement,
If it can be folded and bent freely, it will never break or break. The fish was wrapped with the aluminum hydroxide powder deodorizing paper thus produced and kept, and it did not rot even after 7 days at a temperature of 4 to 5 ° C. and could maintain high freshness. The odor of fish was absorbed by the aluminum hydroxide powder deodorizing paper and did not smell at all. Moreover, it is a flexible deodorizing paper that is very good at packaging and can be freely torn like ordinary paper and can be wrapped without breaking. In addition, pulp
The reason for limiting to 15-40% by weight and 60-85% by weight of aluminum hydroxide is that the amount of pulp less than 15% is not sufficient for producing paper, and if 40% is included, it fulfills the role of papermaking.
Also, if the amount of aluminum hydroxide is less than 60%, the deodorizing effect cannot be sufficiently exerted, and the effect is not increased even if it is added in an amount of 85% or more. Further, the reason why the content of the polymer synthetic paste is limited to 3 to 5% is that the strength becomes insufficient if it is less than 3%. Therefore, at least 3% of the polymer synthetic paste is put in the paper to improve the strength. Further, when the synthetic polymer paste is added to the deodorant paper in an amount of more than 5%, the effect is small relative to the amount added, and the effect of this example can be sufficiently achieved by the addition of 5%. Moreover,
Polyacrylic acid ester or polyacrylamide can exert an effect as a reinforcing material.
