The Department of Agriculture and Supply of the State of São Paulo highlights the significant growth of the national peanut market, with varieties developed through research and rural extension in São Paulo. The Agronomic Institute's Peanut Genetic Improvement Program has developed cultivars that occupy 80% of the planted area in São Paulo, with the most planted varieties being IAC 503 and IAC OL3. Additionally, a study by the Institute of Food Technology found that the majority of industrialized peanut products in Brazil do not contain dyes, antioxidants, or preservatives, and many have positive nutritional characteristics such as proteins and dietary fiber.
