| Outline of Final Research Achievements |
To develop a food antioxidant capacity database, the following results were obtained.
(1) The ORAC assay, which is one of the method to measure antioxidant capacities, was found to have a methodological defect, that is, dilution ratio of tested solutions could affect ORAC values. Thus, the method for the ORAC assay was improved to provide good analytical precision. (2) Some of animal foods such as fishes and meats had considerable antioxidant capacities comparable to vegetables and fruits. (3) Some amino acids may be contributors for antioxidant activities of animal foods. (4) Antioxidants capacities were changed both positively and negatively after cooking.
The quantity and quality of the food antioxidant capacity database obtained here needs to be increased more to be used an epidemiological study in order to clarify the relationship between daily antioxidant intake and health.
