However, Bifidobacterium spp. Are effective in preventing or treating diseases or symptoms such as ulcerative colitis, colon cancer, esophageal cancer, premature birth, and periodontal disease caused by inflammation of mucosal cells. Is not known.
Against this background, there is a demand for ingredients that are effective in preventing or treating diseases or symptoms such as ulcerative colitis, colon cancer, esophageal cancer, premature birth, and periodontal disease caused by inflammation of mucosal cells. ..

On the other hand, Fusobacterium is a resident bacterium in the human oropharynx and is known to be associated with the onset of periodontal disease (Patent Document 3). Furthermore, in recent years, it has been pointed out that Fusobacterium spp. Are associated with ulcerative colitis, colorectal cancer, esophageal cancer, and preterm birth.
It has been reported that a large number of Fusobacterium spp. Inhabit the large intestine of patients with ulcerative colitis and colorectal cancer, and have the ability to adsorb and invade the large intestine mucosal epithelium (Non-Patent Document 1).
In addition, it has been reported that human colon cancer cells express the sugar chain Gal-GalNAc, and Fusobacterium spp. Adsorb to the Gal-GalNAc via Fap2, which is their own Gal-GalNAc-binding lectin. (Non-Patent Document 2).
In addition, when the presence of Fusobacterium was confirmed in 325 cases of esophageal cancer tissue, the presence of Fusobacterium spp. Was confirmed in 74 cases, and it was reported that the prognosis of esophageal cancer was poor (non-patented). Document 3).
In addition, Fap2 contained in Fusobacterium spp. Has been reported to be a galactose-inhibiting adhesion factor involved in preterm birth (Non-Patent Document 4).
Against this background, the development of a composition for suppressing the adsorption of Fusobacterium spp. To mucosal cells is required.

First, the dairy raw material, water if necessary, other components and the like are mixed, preferably homogenized, and heat sterilized. The homogenization treatment and the heat sterilization treatment can be carried out by a conventional method. A lactic acid bacterium starter is added (inoculated) to a heat-sterilized sterilized emulsion and fermented at a predetermined fermentation temperature to obtain a fermented product. Fermentation forms curds.
As the lactic acid bacterium starter, for example, lactic acid bacteria usually used for yogurt production such as Lactobacillus bulgaricus, Lactococcus lactis, and Streptococcus thermophilus can be used. When the pH reaches the target value, the formed curd is crushed by stirring and cooled to 10 ° C. or lower to obtain a fermented product. By cooling to 10 ° C. or lower, the activity of lactic acid bacteria can be reduced and the production of acid can be suppressed.
Next, the fermented product obtained in the fermentation step is heat-treated to obtain a fermented product after heating (fermented product after heat treatment). By appropriately heating the fermented product, it is possible to suppress the production of acid by lactic acid bacteria in the fermented product after heating. As a result, it is possible to suppress a decrease in pH during the subsequent production process and / or during storage of the concentrated fermented milk containing bifidobacteria, and as a result, the survivability of bifidobacteria can be improved.
Next, the Bifidobacterium genus bacterium of the present invention is added to the fermented product after heating obtained in the heat treatment step. The amount of Bifidobacterium to be added is preferably 1 × 10 ⁷ to 1 × 10 ¹¹ CFU / ml, more preferably 1 × 10 ⁸ to 1 × 10 ¹⁰ CFU / ml, based on the fermented product after heating. If the bifidobacteria are dead, CFU / ml can be replaced with individual cells / ml.
After heating, Bifidobacterium spp. Are added to the fermented product and then concentrated. The concentration step can be carried out by appropriately using a known concentration method. For example, a centrifugation method or a membrane separation method can be used.
In the centrifugation method, whey in the concentrate (fermented product after heating to which bifidobacteria are added) is removed to obtain concentrated fermented milk containing bifidobacteria having an increased solid content concentration.
By ingesting the fermented milk obtained as described above, an effect of suppressing adsorption of Fuzobacterium spp. To colon epithelial cells, uterine vascular endothelial cells, esophageal mucosal epithelial cells, and gum mucosal cells can be expected.
