Description

[Technical Field]

[0001] The present invention relates to solid food products. [Background technology]

[0002] In recent years, various studies have been conducted on the normal bacteria in the oral cavity. For example, Patent Document 1 reports that by adding a nitrogen source such as nitrate, non-pathogenic bacteria such as Neisseria bacteria can efficiently produce nitric oxide, thereby controlling the bacterial composition of the oral flora to a favorable level.

[0003] On the other hand, Patent Document 2 discloses a composition for eliminating periodontal disease bacteria present inside oral cells, etc., which contains copper chlorophyllin salt as an active ingredient, and attempts to purify the inside of the cells by killing periodontal disease bacteria that have invaded oral cells. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] US Patent Application Publication No. 2016 / 151428 [Patent Document 2] Japanese Patent Application Publication No. 2023-34874 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the above-mentioned Patent Document 1 only describes the so-called probiotic technology of administering microorganisms themselves to the human body, and does not disclose or suggest any technical idea of ​​promoting the growth of specific microorganisms in the oral cavity. Furthermore, the composition described in Patent Document 2 only kills periodontal disease bacteria, and no consideration has been given to selectively and effectively promoting the growth of Neisseria bacteria in the oral cavity. Thus, there is still ample room for improvement in order to enhance the selective and efficient growth-promoting effect of Neisseria bacteria in the oral flora.

[0006] Therefore, the present invention relates to a solid food that uses a plant-derived powder and selectively and effectively promotes the growth of Neisseria bacteria in the oral flora, thereby effectively improving the oral flora in the oral cavity. [Means for solving the problem]

[0007] Therefore, the inventors conducted extensive research to solve the above problems and discovered a solid food product that contains a chlorophyll metal complex derivative in addition to a plant-derived powder containing nitrate, which can selectively and effectively promote the growth of Neisseria bacteria in the oral flora.

[0008] That is, the present invention provides a composition comprising the following components (A) and (B): (A) Plant-derived powder containing nitrate (B) Chlorophyll metal complex derivatives The present invention provides a solid food product containing the above. [Effects of the Invention]

[0009] The solid food of the present invention, when simply introduced into the oral cavity, selectively promotes the growth of Neisseria bacteria in the oral cavity and also promotes the growth of not only Neisseria bacteria but also Russula bacteria, thereby selectively suppressing the growth of pathogenic bacteria and effectively improving the oral flora. Furthermore, after storage, the solid food exhibits good stability by suppressing unwanted discoloration and changes in flavor. DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described in detail below. In the present invention, the term "oral flora" refers to a community of various bacteria that inhabit the oral cavity and are broadly classified into non-pathogenic bacteria and pathogenic bacteria. Such "oral flora" is also called "oral (oral or oral cavity) flora" or "oral (oral or oral cavity) microbiota." "Improving" the oral flora means changing the bacterial composition of the oral flora by increasing the proportion of non-pathogenic bacteria or decreasing the proportion of pathogenic bacteria, thereby converting the state of the oral flora to one that leads to a healthy oral environment. Specifically, this means that the metabolism of Neisseria and Russia bacteria is activated in the oral cavity, selectively promoting their growth, thereby increasing the proportion of these non-pathogenic bacteria (Neisseria or Russia bacteria) in the oral flora; it also means that the growth of pathogenic bacteria is selectively suppressed, thereby increasing the proportion of bacteria such as Neisseria bacteria in the oral flora.

[0011] Here, the genus Neisseria refers to non-pathogenic, normal oral bacteria belonging to the genus Neisseria in the family Neisseria, including Neisseria mucosa, Neisseria sicca, Neisseria flava, Neisseria subflava, Neisseria flavescens, and Neisseria elongata. Rothia species are Gram-positive cocci or bacilli belonging to the Micrococcaceae family, and are non-pathogenic, normal inhabitants of the oral cavity. The genus Rothia includes species such as Rothia aeria, Rothia mucilaginosa, and Rothia dentocariosa.

[0012] Furthermore, "nitrate retention" means that after being placed in the mouth, solid food gradually dissolves and diffuses in the mouth, and as a result, nitrates remain in the mouth sufficiently. Furthermore, "good stability" means that even when stored in a long-term environment, the product will not discolor unnecessarily, and the flavor will not change or be impaired, ensuring good quality.

[0013] The solid food of the present invention contains a plant-derived powder containing nitrate as component (A). Plant-derived powder is a powder obtained by processing a plant as a raw material, such as pulverization, followed by appropriate drying. In the present invention, a nitrate-containing powder is used as component (A). By ingesting the solid food of the present invention into the oral cavity, the nitrate contained in component (A) is released as nitrate (NO3) ions until the solid food dissolves and diffuses, thereby increasing the growth-promoting effect of Neisseria and russian bacteria in the oral flora and effectively improving the oral flora. Although the detailed mechanism of the oral flora-improving effect of the solid food of the present invention is unclear, it is thought that when the normal oral bacteria, Neisseria and Russula, produce nitric oxide using nitrate (NO3) ions released from the nitrate contained in component (A), the chlorophyll metal complex derivative of component (B), described below, exerts some kind of synergistic effect. As a result, these components significantly contribute to promoting the growth of Neisseria and Russula, and are presumed to rapidly increase the proportion of Neisseria and Russula in the oral flora.

[0014] Component (A) may be any substance containing nitrate, and specific examples include powders of one or more types selected from sweet potato leaves, kale, barley, celery, Japanese mustard spinach, parsley, spinach, radish, beets, broccoli, burdock, and aloe.

[Example]

[0041] The present invention will be described in detail below with reference to the following examples. Unless otherwise specified in the tables, the content of each component is expressed in mass %.

[0042] [Examples 1 and 2, Comparative Example 1] According to the formulation shown in Table 3, the ingredients were mixed and molded using a hydraulic tablet press to obtain tablets (1.9 g / tablet). The obtained tablets were used to evaluate the oral flora improving effect according to the following method. The results are shown in Table 3.

[0043] <Evaluation of oral flora improvement effect> 1) Calculation of the ratio of each bacteria Six subjects were instructed to take each tablet three times a day (one tablet each time) for three days, and the bacterial ratios in stimulated saliva before and after ingestion were compared. In addition, the subjects were instructed to use the designated commercially available toothpaste and toothbrush from one week before taking the tablets until the end of the test period, to eliminate the influence of oral hygiene practices other than tablet ingestion. The stimulated saliva was collected by chewing commercially available paraffin wax gum for 3 minutes, and the leaked saliva was spat out into a plastic container at regular intervals. After collection, the saliva was promptly stored in a freezer at -20°C.

[0044] Next, 500 μL of stimulated saliva was collected after storage, and genomic DNA was extracted using a PureLink Microbiome DNA Purification Kit (Thermo Fisher). The proportion of each bacterium was calculated using real-time PCR with a Taqman probe. The primers and Taqman probes used and the reaction conditions for real-time PCR are shown in Tables 1 and 2.

[0045] [Table 1]

[0046] [Table 2]

[0047] 2) Calculation of the relative increase rate of each bacterium and the improvement rate of the bacterial flora The abundance ratio (%) of each bacterium was calculated by first creating a calibration curve using PCR products with known copy numbers as standards, then calculating the copy number of the rRNA16S gene of each bacterium using the following formula. Percentage of each bacterium present (%) = (copy number of each bacterium) / (total bacterial copy number) × 100 The relative growth rate of each bacterium was calculated using the following formula. Relative increase rate of each bacterium (%) = (proportion of each bacterium present after 3 days of intake) / (proportion of each bacterium present before intake) × 100 Bacterial flora improvement rate = (relative increase rate of Neisseria + relative increase rate of Russia) / (relative increase rate of Prevotella + relative increase rate of Veillonella)

[0048] [Table 3]

[0049] [Examples 3 to 5] According to the formulation shown in Table 4, each tablet (1.9 g / tablet) was obtained in the same manner as in Example 1. Using the obtained tablets, including those of Examples 1 and 2 and Comparative Example 1, evaluation of discoloration inhibition after storage was carried out according to the following method. The results are shown in Table 4.

[0050] <Evaluation of discoloration prevention after storage> The resulting tablets were placed in an aluminum pouch, sealed with a heat sealer, and then stored in a constant temperature cabinet at 5°C and 60°C for 5 days. Next, the a and b values ​​of each tablet after storage were measured using a Konica Minolta color difference meter, and the color change (Δab) value was calculated using the following formula, which was used as an index for evaluating discoloration inhibition. The smaller the value of the obtained color change (Δab), the better the color change suppression effect can be evaluated. Color change after storage (Δab) = (absolute a value + absolute b value of sample stored at 60°C) - (absolute a value + absolute b value of sample stored at 5°C)
