Rizzo, who last year became the first winner of Veuve Clicquot's Latin America's Best Female Chef, will receive the award at a ceremony in London next month.
She takes the award from Italian Nadia Santini, who cooks at the three-Michelin-starred "Dal Pecatore" in Canneto sull'Oglio, Lombardy.
Rizzo apprenticed at Spain's El Celler de Can Roca, currently rated as the world's best restaurant.
She opened Mani with her husband, chef Daniel Redondo, in 2006. Their specialty is an interpretation of classic Brazilian Maniocas baked and served with a foam tucupi sauce, coconut milk and oil with white truffle.
"I am not and have never intended to be 'the best female chef in the world'," Rizzo said of the award.
"I hope that this award makes the gastronomic world open its eyes to the work of female cooks and to the wonderful kitchens we have in Brazil."
The list of 2014's top 50 restaurants will be announced on April 28 at a London reception organized by British magazine Restaurant.
