Cookies are a group of convenient food products that are popular among consumers. They may contain high amounts of fats, which can be prone to oxidation.

It was shown that thyme extract can be used as a natural antioxidant source for the preparation of bakery products, while the rosemary extract should be used with care in fat-rich products exposed to high temperatures.
