Food functionalities have been forcused, and many kinds of functionaliry labeled food items are available. In addition, it has been well recognized that gut microbes play important roles in our health. Lactic acid bacteria (LAB) are recognized as beneficail microbes in the gut, and they are also indispensable for production of fermented food. Probiotics are viable bacteria which contribute our healthy state, and prebiotics contribute our health by improving gut atmosphere. We are interested in functionalities of LAB from fermented food, and in the possibilities of enhancemnet of food functionalities by prebiotics via improving gut envilonment.

List of current research topics

Anti-metabolic syndrome effects of probiotic lactic acid bacteria via modulation of circadian rhism.
Bio-conversion of food functional factors by intestinal microbiota.
Effect of culture conditions on immunomodulation activities of lactic acid bacteria.
