How do scientists measure antioxidant content of foods?
Scientists use several tests to measure the antioxidant content of foods. One of the best tests is the FRAP (ferric reducing ability of plasma) analysis. It measures the antioxidant content of foods by how well they can neutralize a specific free radical ( 2 ). The higher the FRAP value, the more antioxidants the food contains.
Are natural antioxidants an alternative to synthetic antioxidants in food processing?
DC, Salvia officinalis L., Momordica Charantia L., Rheum ribes L., and Pelargonium endlicherianum. The literature reveals that these natural antioxidants represent a potentially side effect-free alternative to synthetic antioxidants in the food processing industry and for use in preventive medicine.
What are antioxidants and why are they important?
Antioxidants help prevent oxidation, which can cause damage to cells and may contribute to aging. They may improve im- mune function and perhaps lower the risk for infection, cardiovascular disease, and cancer. Antioxidants exist as vitamins, minerals and other compounds in foods.
