  Caffeic and Gallic Acids Protect Commercial Infant Milk Formula from Oxidative Damage
  Author(s): Oshra Saphier*, Tamar Barak, Batel Hamou and Tali Silberstein
  
  Objective: To determine whether the addition of polyphenols (gallic and caffeic acids) to infants milk substitutes, prevents oxidation of unsaturated fatty acids, under conditions of oxidative stress. Materials and methods: In order to induce controlled oxidative stress we used ultraviolet radiation UV-C 254 nm with energy doses in the range of 0-14 J/ml. We followed lipid peroxidation by the thiobarbituric acid reactive substances (TBARS) assay in order to measure the amount of secondary oxidation products, malondialdehyde (MDA). Polyphenols were added to the type specified the range of 0-3 mM concentrations. To measure the change polyphenols amount, the method of Folin-Ciocalteu assay was used. Results: We have proved that UV-C radiation is able to oxidize PUFA. We found a direct relationship between radiation do.. View More»
