Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 879-892, March/April 2026.Abstract Guaraná (Paullinia cupana) is a fruit native to the Amazon region. Due to its widespread use, primarily in beverages, its production has grown over the years. The seed is the only commercially valuable part of the fruit so the guaraná production chain generates byproducts, including peel, husk, and spent seed.
