Measuring antioxidants
Measuring antioxidants
There is growing evidence that dietary antioxidants – such as vitamins C and E, anthocyanins and polyphenols can help reduce risks of cardiovascular disease and some cancers. This has stimulated interest in measuring the antioxidant capacity of foods. Claims relating to dietary sources of natural antioxidants have provided a marketing opportunity for food producers, while nutritionists and consumers are looking for data to compare products.
CCFRA offer analytical services to meet this demand. For example, ORAC – the oxygen radical absorbance capacity – can provide a comparative measure of the antioxidant capacity of foods. Total polyphenols can also be measured by a fast yet robust test method – again allowing useful comparisons.
For wider comparisons we can also compare the data obtained for particular products with values published by the United States Department for Agriculture, for over 100 different foods.
