Food chemistry

The Laboratory of Food Chemistry concentrates on the functions of foods such as vegetables, herbs, buckwheat, and mushrooms. Our primary aim is to study these functions by utilizing various organic and analytical chemistry techniques.
Research includes the elucidation of the angiotensin-I-converting enzyme inhibitor of various vegetables, buckwheat, and mushrooms. Investigations aimed at finding digestive enzyme inhibitors from mushrooms have been conducted.
Changes in the amount of flavor compounds such as amino acids and 5�-nucleotides of cooked or processed mushrooms have also been investigated.
