Fragaria genus (Rosaceae), commonly known as strawberry, represents one of the most important food plants all over the world, with a double global production compared with all other fruit berries combined. Usually appreciated because of their specific flavor, the strawberries also possess biological properties, including antioxidant, antimicrobial, or anti-inflammatory effects.
