Researchers from Embrapa are conducting a study to determine the optimal concentration of turmeric in Flour produced in the Juruá Valley of Acre, Brazil. The study aims to ensure that the flour's quality and legal standards are met, while achieving the desired color. The flour will also be analyzed for its proximate composition, acidity, pH, colorimetry, and starch content. This research is essential for maintaining product uniformity, especially for flours being marketed by Central Juruá with Geographical Indication. Sensory analysis of the flours will be done to evaluate color, aroma, flavor, texture, and purchase intention of local consumers.
