We confirmed that the pasteurization process after fermentation is involved in the physiological functions of pasteurized yogurt by analyzing trace components, including metabolites in fresh and pasteurized yogurt. Our results suggest that this pasteurization may positively affect yogurt’s physiological function. |

| Summary |
Change in beating speed in the middle of whipping process brought short whipping time and high shape-retention ability to whipped cream. In this whipping condition, the size of air bubble in whipped cream became smaller than regular ones, thus the small bubble size could be one of the reasons for this effect. |

| Summary |
The nine candidates of prebiotics for Faecalibacterium prausnitzii that is butyrate producer were evaluated using a pH-controlled single-batch fermenter as a human gut microbiota model. Of them, alginate markedly increased the relative abundance of F. prausnitzii. Nevertheless, F. prausnitzii strains were incapable of utilizing alginate in monoculture. The co-culture with Bacteroides revealed that some F. prausnitzii strains assimilate Bacteroides-degraded alginate oligomers. |

Gut Microbes 13(1): 1-11 (2021) |
| Summary |
Fecal metabolites in Japanese healthy elderly subjects, who fell into an age-matched or an age-mismatched cluster, were measured. We found some metabolites elevated in the aged gut microbiota were metabolites reported as risk factors for age-associated diseases such as arteriosclerosis and colorectal cancer. These findings suggest that metabolites produced by the aged gut microbiota could contribute to intestinal and systemic homeostasis and could be targeted for preventing aging-associated diseases. |

| Journal |
Microorganisms 8(3). Pii: E398 (2020) |
| Summary |
Gut microbiota-derived tryptophan metabolites could mediate gut-brain communication. Infant-type Human-Residential Bifidobacteria (HRB) produced higher levels of indole-3-lactic acid (ILA). We found that ILA enhanced NGF-induced neurite outgrowth of PC12 cells in a dose-dependent manner. ILA potentiated neurite outgrowth through the Ras/ERK pathway, and also in an aryl hydrocarbon receptor (AhR)-mediated manner. These new findings provide clues into the potential involvement of ILA as the mediator in bifidobacterial host-microbiota crosstalk and neuronal developmental processes. |

| Summary |
We examined the production of Indole-3-lactic acid (ILA) by Bifidobacterium strains found in the gastrointestinal tracts of humans and other animals. Strains of bifidobacterial species commonly isolated from the intestines of human infants, such as Bifidobacterium longum subsp. longum, Bifidobacterium longum subsp. infantis, Bifidobacterium breve, and Bifidobacterium bifidum, produced higher levels of ILA than did strains of other species. |

| Summary |
Sharing of Bifidobacterium longum strains had recently been shown to occur among Japanese family members, a phenomenon that is not confined to mother-infant pairs. In the current study, we investigated if bathtub water is a possible vehicle for the exchange of strains as a consequence of a Japanese custom to share bathtub water by family members during bathing practices. Viable bifidobacterial strains were isolated from all bathtub water samples. We showed that the fecal microbiota composition among family members that share bathtub water is significantly closer than that between family members that do not engage in this practice. Our results indicate that bathtub water represents a vehicle for the transmission of gut bacteria, and that the Japanese custom of sharing bathtub water contributes to the exchange of gut microbes, in particular bifidobacteria, among family members. |

As results, a broad distribution of them across the human lifespan is due to a high transfer level between family members. We furthermore identified a variety of genes which could enhance their adaptation and increase competitiveness in the gut environment, enriched in genomes corresponding to specific ages. |

| Summary |
In this study, we conducted clinical trial to evaluate the effects of Aloe sterols on glucose metabolism. Healthy subjects were allocated to an Aloe sterol group or a placebo group, and ingested Aloe sterol capsules or placebo capsules daily for 12 weeks. An oral glucose tolerance test (OGTT) was carried out at 0 and 12 weeks. As results, the changes at 0 and 12 weeks in blood glucose levels at 60 minutes after OGTT and blood glucose AUC were significantly lower in the Aloe sterol group than placebo group, even though there was no difference in blood insulin levels. From these results, it is considered that dietary supplementation with Aloe sterol has the beneficial effect of lowering postprandial blood glucose levels by improving insulin sensitivity in healthy individuals. |

| Summary |
In a study of 60 healthy Japanese women, the 2 g/day lactulose ingestion for 2 weeks significantly increased the human gut-resident bifidobacteria: B. adolescentis, B. catenulatum,, and B. longum. However, it did not significantly affect the diversity of the intestinal microbiota. |

| Summary |
We conducted a 24-week, randomized, double-blind, placebo-controlled trial to investigate the ability of the casein-derived peptide Met-Lys-Pro (MKP) to improve cognitive function in a population of community-dwelling adults without dementia. The present study showed that MKP supplementation may have the potential to improve orientation. |

| Summary |
We investigated the effect of lactoferrin (LF)-fortified formula on gastrointestinal and respiratory symptoms in children aged 1-2 years. This investigation demonstrated that ingestion of LF could decrease the prevalence of acute gastrointestinal symptoms and lower the total days of acute respiratory symptoms in children. |

| Summary |
We conducted the clinical trial to evaluate the influence of long‐term use of LF and LPO‐containing tablets on gingival health and oral health‐related quality of life in healthy subjects. Long-term ingestion of tablets containing lactoferrin and lactoperoxidase significantly improved gingival inflammation and oral health‐related quality of life compared with the placebo. |

| Summary |
We examined the effects of milk casein hydrolysate intake on the body composition of healthy women doing habitual exercise in fitness clubs. In conclusion, no obvious effects of the casein hydrolysate intake on the body composition could be confirmed. However, it was suggested that there may be some influence on the body composition or energy metabolism in a certain populations. |

| Summary |
We have identified five phytosterols (Aloe sterol) obtained from Aloe vera gel as functional ingredients. We investigated the effects on skin function by basic and clinical studies. From these studies, it was confirmed that the usefulness of Aloe sterol on maintenance and promotion of skin health as functional food material. |

| Summary |
In a randomised, double-blind crossover trial with 60 healthy Japanese women, the defaecation frequency, faecal consistency, faecal volume, and the number and percentage of Bifidobacterium in faeces were significantly higher during 2 g/day lactulose than placebo, but flatulence was unchanged. |

| Summary |
We assessed changes in defaecation frequency following ingestion of 1, 2, or 3 g/day of lactulose for 2 weeks. This was an open-label, before-after trial that enrolled 26 healthy Japanese women. The defaecation frequency, number of defaecation days, and number of faecal bifidobacteria increased significantly compared with before ingestion of 1, 2, and 3 g/day of lactulose. |

| Summary |
We compared protein digestibility and glucagon-like peptide-1 (GLP-1) -releasing activities of micellar casein concentrate (MCC) and sodium caseinate (SCN). The digestibility of MCC was higher than that of SCN. A comparison of GLP-1-releasing activities showed that MCC induced GLP-1 secretion to a greater extent than SCN. |

| Summary |
We evaluated predominant odorants of Whey protein hydrolysates(WPH), and our results showed that difference of odor characteristics between whey protein concentrate(WPC) and WPH, and three odor-active compounds contributed to the odor of WPH. Additionally, this study suggests that specific free amino acids are important precursors for generation of these compounds in manufacturing process of WPH. |
