Since the unreacted residual acid is retained in the voids in the pearl layer (8) in the water quality improving agent (2), if the enclosed pack (1) is put into water, it will be contacted with water. The above reaction proceeds again to generate carbon dioxide. The carbon dioxide thus generated exerts a reducing property during the generation period thereof, and changes the double bond of the organic compound, which is the odor and color group, into a single bond. Therefore, the object to be treated (food or the like) immersed in water is deodorized and decolorized.

As shown in FIG. 5, first, the pearl layer (8) separated from the oyster shell (5) is heated and dried to distort the crystalline portion (9) and the amorphous portion (10). A fine void is formed between the two. Next, this pearl layer (8) is put into an acid aqueous solution such as hydrochloric acid to carry out a first acid treatment, and is left as it is until carbon dioxide is not generated. Next, the pearl layer (8) is washed with water and immersed in water,
The acid is supplied again to perform the second acid treatment. In the second acid treatment, initially CaO and C contained in the pearl layer (8) were used.
Although aCO 3 and the like float and the aqueous acid solution becomes cloudy, when an excess amount of acid is further added, these become soluble salts (CaCl 2 and the like) and are ionized, so that the aqueous acid solution becomes transparent. When it becomes transparent, the pearl layer (8) is taken out from the water and dried, and as in the case shown in FIG. 4, the pearl layer (8) is removed.
Residual acid is retained in the voids inside. Therefore, when this is put into water, the above-mentioned reaction is restarted to generate carbon dioxide, and the object to be treated is deodorized and decolorized. With this procedure, CaO and Ca when the enclosed pack (1) is loaded
Since the amount of CO 3 or the like suspended in water is reduced, high hygiene can be ensured.

As described above, when the water quality improving agent-enclosed pack according to the present invention is put into water, the residual acid retained in the pearl layer reacts with the calcium compound contained in the pearl layer or ground shell. , Because carbon dioxide is generated,
Due to the reducibility exhibited by nascent carbon dioxide, it is possible to easily and safely deodorize and decolorize the object to be treated (food, etc.). Also, since the water quality improver is enclosed in the bag,
The water quality improver does not disperse in water during use, and therefore, there is no risk that the water quality improver will be mistakenly taken into the human body when eating or drinking the object to be treated.
