Reexamination of the ORAC assay: effect of metal ions
Analytical and Bioanalytical Chemistry, 2011The oxygen radical absorbance capacity (ORAC) assay method has been employed extensively in the field of antioxidant and oxidative stress. It uses fluorescein as probe for oxidation by peroxyl radical. Hundreds of reports have been published on the use of this method to determine antioxidant capacity in food and biological samples.

Comparison of scavenging capacities of vegetables by ORAC and EPR
Food Chemistry, 2014Reactive oxygen species (ROS) are considered to be causative agents of many health problems. In spite of this, the radical-specific scavenging capacities of food samples have not been well studied. In the present work, we have developed an electron paramagnetic resonance (EPR) spin trapping method for analysis of the scavenging capacities of food ...

Measuring Antioxidant Capacity Using the ORAC and TOSC Assays
2009Recent epidemiological studies have shown that there may be a link between oxidative stress and the development of several types of chronic diseases. Studies have also shown that diets rich in fruits and vegetables may decrease the incidence of cancer and other chronic diseases.

ORAC: It Pipes, Therefore It Is
2016The ideas which crystallised into the ORAC project developed gradually at the JAC during the mid-1990s. Key to the process was probably Alan Bridger, head of the UKIRT software group, who had been thinking for some time about how to radically improve UKIRT’s end-to-end software system to make it easier to maintain and upgrade. In this he was not alone.

Variability of oxygen radical absorbance capacity (ORAC) in different animal species
Free Radical Research, 1998The oxygen radical absorbance capacity (ORAC) was measured both in whole (ORAC-T) and deproteinized (ORAC-AS) plasma samples of human, pig, cow, rabbit, dog, cat, sheep, horse, dolphin, turkey, guinea-hen and chicken. In the 12 species, ORAC-T data, expressed as micromoles of peroxyl radicals trapped by 11 of sample, were found scattered between 8,600 ...

Use of ORAC to assess antioxidant capacity of human milk
Journal of Food Composition and Analysis, 2009Abstract The oxygen radical absorbance capacity (ORAC–FL) assay, a useful measure of the antioxidant capacity (AC) reported for some biological samples, supplements, and food samples, was standardized and validated for measuring AC of human milk.

ORAC VRIJEDNOSTI EKVIMOLARNIH FENOLNIH SMJESA
2020Fenoli su najzastupljeniji organo-kemijski spojevi u prirodi. Ova grupa sekundarnih biljnih metabolita ima razne uloge u prirodi, ali ipak najvažnija je ona antioksidacijska koja ovisi o nekoliko čimbenika. Cilj ovo rada bio je analizirati smjese fenolnih kiselina i to iz podgrupa derivata hidroksibenzojeve i derivata hidroksicimetne kiseline metodom ...

Validacija ORAC metode i utvrđivanje antioksidativnog kapaciteta brašna rogača ORAC metodom
2013Rogač (Ceratonia siliqua, Fabaceae) je tradicionalna biljka sa područja Mediterana koja ima vrlo dobru nutritivnu vrijednost te je veoma cijenjena zbog kemijskog sastava ploda bogatog polisaharidima, lipidima, bjelančevinama, mineralima, vitaminima te antioksidansima. Antioksidansi se danas dodaju u prehrambene proizvode ili se traže namirnice prirodno
