| Research Abstract |
At the time of lactation mastitis, infants sometimes refuse to suckle from a breast with mastitis. The refusal of infants to suckle suggests that the taste of the milk has changed. By comparison, in milk between breasts inflamed due to mastitis and normal breasts, the intensity of umami increased in milk from inflamed breasts. In milk from inflamed and contralateral asymptomatic breasts of mothers with unilateral mastitis, the intensity of umami and saltiness was increased in milk from inflamed breasts. Concentrations of glutamate, 5'-GMP and sodium increased, whereas calcium concentrations decreased in it. Therefore, we concluded that the intensity of both umami and saltiness increased in milk from the inflamed breasts of mothers with mastitis. In addition, I was measured brain waves of breast-feeding infant. As a result, breast-fed infants, reduction of beta waves and an increase in alpha wave was observed in the breast-feeding and post-lactating than before breast-feeding.
