Description

The present invention relates to a confectionery material capable of suppressing tooth decay, gum, and a method for producing gum.

Streptococcus mutans (hereinafter referred to as "mutans mutans") is a type of gram-positive and facultative anaerobic streptococcus that is present in the human oral cavity and is one of the causative bacteria of caries (caries). It is a fungus that becomes one. In tooth decay, mutans bacteria break down (metabolize) sugar in plaque to produce acid, which dissolves the enamel on the surface of the tooth and caries the dentin beneath it and the cementum inside it. By doing so.

In order to prevent tooth decay, it is considered important to take foods that reduce mutans bacteria in the oral cavity along with habits such as brushing teeth. As the food, for example, xylitol, which is a synthetic sweetener, is known, but in fact, its effectiveness in preventing dental caries has not been proved, and if it is ingested too much, it causes diarrhea, so that it is suitable for people with weak intestines. There is a problem that it is not suitable.
Fluoride is also said to be effective, but it has been pointed out that it is dangerous as a cause of cancer and cranial nerve damage because it has a strong antioxidant effect. Further, oolong tea extract, Chinese pepper oil, Kuro-moji extract and the like are also known, but their effectiveness has not been proved.
As a gum for preventing dental caries, Patent Document 1 proposes a gum containing a porous carbon material having a specific pore volume.

In addition, safety has been confirmed in the results of an acute oral toxicity test using rats, a mutagenicity test, and a primary skin irritation test using rabbits.

[Gum manufacturing method]
The method for producing a gum of the present invention is a method for producing a gum, which comprises a step of mixing an alkaline compound and a wetting agent to prepare a dental caries preventive ingredient and a step of mixing the dental caries preventive ingredient and a gum base in this order. According to the present invention, since the alkaline compound can be uniformly mixed with the gum base, the effect of preventing dental caries can be obtained even more effectively.

In the production method of the present invention, the alkaline compound is preferably calcium hydroxide obtained by grinding scallop shells or chicken egg shells, and the wetting agent is more preferably propylene glycol. Calcium hydroxide obtained by crushing scallop shells or chicken egg shells has a small average particle size, so it is difficult to mix with the gum base. Therefore, by preparing a dental caries preventive component in which calcium hydroxide and propylene glycol are mixed in advance and mixing this with a gum base, it becomes possible to produce a gum containing the dental caries preventive component uniformly.
The method of mixing calcium hydroxide derived from scallop shells or chicken egg shells and propylene glycol is not particularly limited, and for example, by mixing both in a mortar or the like, a dental caries preventive component can be obtained.

Hereinafter, the present invention will be described in more detail with reference to Examples and the like, but the present invention is not limited to such Examples and the like.
<Example 1: Production of evaluation gum>
The evaluation gum was prepared by the following procedure.
(1) A general gum base containing no xylitol was shredded and immersed in warm water for one day. Then, the hot water was replaced and the work of immersing again for 1 day was performed for a total of 3 days to remove the fragrance and sugar contained in the gum base.
(2) While heating the obtained gum base, a so-called sugarless sweetener such as sugar alcohol was mixed.
(3) Calcium hydroxide (average particle size 3.5 to 10 μm) obtained by finely pulverizing scallop shells and treating with water and propylene glycol were kneaded in a mortar to prepare a tooth decay preventive component.
(4) The dental caries preventive component obtained in (3) above and the gum base obtained in (2) above were mixed so as to be uniform to obtain a confectionery material (gum material). The amount of calcium hydroxide in 100% by mass of the obtained confectionery material was 1.5% by mass.
(5) The obtained confectionery material was cooled, then stretched and molded, and cut into a chewing gum shape.

<Evaluation method>
The evaluation gum was inspected for "bacteriostatic effect of mutans bacteria" according to the following procedure.
First, pseudo-saliva (purified water having a pH of 7.0: equivalent to human saliva) was used to bring the evaluation gum (20 pieces of plate gum, about 40 g) into a state similar to that actually chewed. Specifically, the evaluation gum was repeatedly crushed using a cooking utensil for about 10 minutes while adding pseudo saliva to obtain 100 ml of a test solution as pseudo chewing saliva.
Next, Streptococcus mutans was added to the test solution, and changes in viable cell count over time were observed. The test was conducted at the Japan Food Research Laboratories. The results are shown in Table 1.

One minute after the start of the test, it decreased by 37.5% as compared with the start of the test, and five minutes later, it decreased by 93.2%. After another 15 minutes, only 0.0053% of the viable bacteria were present at the start of the test. That is, according to the present invention, mutans bacteria can be remarkably reduced, and as a result, a caries preventive effect can be expected.

<Example 2: pH evaluation of calcium hydroxide derived from chicken egg shell and calcium hydroxide derived from scallop shell>
Calcium hydroxide derived from chicken egg shell and calcium hydroxide derived from scallop shell were dissolved in pure water to prepare 1% by mass aqueous solution of each. For each aqueous solution, the pH of each aqueous solution was measured once a day using a digital pH meter "DPH-2" manufactured by Atago Co., Ltd., and the transition of pH was observed. The results are shown in FIG.
Both calcium hydroxide derived from chicken egg shells and calcium hydroxide derived from scallop shells were obtained by firing, finely pulverizing, and treating with water, and had an average particle size. Was 3.5 to 10 μm.

As is clear from the results shown in FIG. 1, the pH of calcium hydroxide derived from the eggshell of chicken eggs is lower than that of calcium hydroxide derived from the shells of scallops, and even after 2 weeks have passed since the sample was prepared. It maintained high alkalinity. Therefore, it is presumed that calcium hydroxide derived from the eggshell of a chicken egg can effectively suppress the occurrence of tooth decay to the same extent as or more than the calcium hydroxide derived from the shell of a scallop.
