The effect of palatinose intake on α1 brain wave generation was studied by human volunteer test. Twelve healthy volunteers were administered 40 g of palatinose or sucrose, and electroencephalogram (EEG) was made before and at 150 min after administration. The area of α1 wave generation on topographs increased after administration of either sugar, but there was a significant difference in the intensity between the palatinose and sucrose groups. Ten volunteers were administered 100 mg of theanine, which has a relaxing effect, in combination with 17.5 g of palatinose (T-P group), and EEGs were recorded before, at 60 and 150 min after administration. Though the area of generated α1 brain wave in the topographs increased in both groups (T-P and 17.5 g palatinose groups) after administration, the patterns of their increase differed. Nine volunteers were administered 5 g of palatinose, and EEGs were recorded before and at 150 min after the administration. The area of α1 wave generation increased slightly but less than that in 40 g palatinose group. The above results suggested that palatinose enhances generation of α waves and that its effect might be maintained longer than that of sucrose.
