Within 24 hours of delivery, 16 breast milk samples from mothers of term and preterm infants were divided into aliquots. Fresh samples were immediately tested for antioxidant activity based on their ability to inhibit the oxidation of 2,29-azino-di-3- to its radical cation compared with Trolox, a strong antioxidant that is a derivative of vitamin E. The remaining aliquots were stored at –20 C or 4 C for analysis at 48 hours and at seven days.
