A research project in Brazil is conducting sensory analysis of cassava flour with different concentrations of turmeric, a natural coloring, as part of the 'Consolidation of the Cruzeiro Sul Geographical Indication' project. The study, which began in 2015, aims to understand consumer preferences and establish official use of saffron by flour producers, with the possibility of adding value to the product. The research also focuses on safety and health aspects, and is supported by the Mandiotec Project, which is funded by the Amazon Fund and BNDES, with the goal of enhancing the cassava production chain in the Juruá region.
