Course Goal / Objective

The aim of this course is to provide students with comprehensive information about the sources, chemical structures, mechanisms of action, and effects on human health of natural antioxidants. The course covers the relationship between plant- and animal-derived natural antioxidants and oxidative stress, their role in preventing chronic diseases, and the preservation and evaluation of antioxidant activity in foods, all in light of scientific principles. The goal is for students to gain the ability to analyze current scientific literature on natural antioxidants and apply this knowledge to food and health applications.

Course Content

This course covers the sources of natural antioxidants, their mechanisms of action, and their roles in human health. Oxidative stress, antioxidant defense systems, and natural antioxidant compounds are examined.

Course Precondition

Resources

Measurement of Antioxidant Activity in Food and Biological Systems Journal of AOAC International
