The nutraceutical properties of "pizza marinara TSG" a traditional food rich in bioaccessible antioxidants

Italian gastronomy experiences have ever-enhancing fame around the world. It is due to the linkage between taste and salubriousness commonly related to Mediterranean foods. The market proposes many types of pizza to suit all palates. In this work, the antioxidant potential of the "pizza “marinara” included in the register of traditional specialties guaranteed (TSG) was determined. ABTS method evaluated the antioxidant activity of the pizza homogenized. In vitro digestion models estimated the intestinal and gastric bioaccessibility of the main antioxidant compounds (lycopene and phenolics). To our knowledge, this is the first study to provide the content, antioxidant potential, and bioaccessibility of the antioxidants (polyphenols and lycopene) contained in the traditional pizza “marinara TSG”. Our results showed that the "pizza marinara TSG" had polyphenols concentration, lycopene level, antioxidant activity, and bioaccessibility of phenolic compounds and lycopene better than other similar pizzas. They confirmed the nutritional importance of traditional preparations and established the functional potential of "pizza marinara TSG" as a food rich in bio-accessible antioxidants.
