Unicamp team uses sugar-based solvent to pull caffeine and antioxidants from guarana peel
Researchers at Brazil's State University of Campinas (Unicamp) have developed a method to extract caffeine and antioxidants from guarana peels that replaces toxic solvents.
Why it matters: Unicamp's researchers report an extraction method for guarana peel that substitutes toxic solvents and cuts energy use.
Researchers at the Universidade Estadual de Campinas (Unicamp, the State University of Campinas) have developed a 'green' method for extracting caffeine and antioxidants from guarana peels, according to a Jornal Cana report published by Inova Unicamp, the university's innovation agency.
The method uses a sugar-based solvent, the report said.
According to the report, the approach replaces toxic solvents and reduces energy consumption, and it describes the method as innovative and sustainable.
