The ORAC‐DR data reduction pipeline

Astronomische Nachrichten, 2008
AbstractThe ORAC‐DR data reduction pipeline has been used by the Joint Astronomy Centre since 1998. Originally developed for an infrared spectrometer and a submillimetre bolometer array, it has since expanded to support twenty instruments from nine different telescopes. By using shared code and a common infrastructure, rapid development of an automated

Reexamination of the ORAC assay: effect of metal ions

Analytical and Bioanalytical Chemistry, 2011
The 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.

Antioxidant activity of protocatechuates evaluated by DPPH, ORAC, and CAT methods [PDF]

Food Chemistry, 2016
Hibiscus sabdariffa L. is a worldwide consumed plant, principally after infusion of its dried sepals and calyces, which are usually discarded. Nevertheless, they represent a potential source of natural bioactive compounds, e.g. polyphenols, which could add value to this under-exploited plant.

Fast ORAC-SIA method for antioxidant capacity determination in food samples

Food Chemistry, 2022
A novel fluorescent ORAC-SIA method to determine antioxidant capacity in several food samples using fluorescein as the probe was developed. The optimization of the method was through a multivariable design, decreasing the analysis time to 5 min and the AAPH concentration to 67% compared with 90 min in the standard 96-well microplate method.

Comparison of scavenging capacities of vegetables by ORAC and EPR

Food Chemistry, 2014
Reactive 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

2009
Recent 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

2016
The 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, 1998
The 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 ...
