In recent years, there has been a global trend towards the use of the natural substances present in the food as a source of antioxidant and functional ingredients. Especially natural antioxidants present in food have received considerable interest because of their safety and potential nutritional and therapeutic effects. Bread and bakery products have an important role in human nutrition. Generally, wheat bread is considered to be a good source of energy and irreplaceable nutrients for the human body.
