ABSTRACT The objective of this research work was to determine the amount of total polyphenols present in the dye of the Hibiscus sabdariffa flower and to formulate a jam. The extraction of the dye was carried out by the percolation method and the quantification of the total polyphenols was carried out by the spectrophotometric method, in addition, jams were formulated considering three concentrations of dye (0.5%; 0.75% and 1%). The following was obtained as a result: Total polyphenols present were 36.83 milligrams for each milliliter of extract and jams at different concentrations of dye. It is concluded that total polyphenols were found in the colorant extracted from the Hibiscus sabdariffa flower in a concentration of 36.83mg/ml expressed in gallic acid and that the best jam formulation was with 1% colorant since it maintained a more intense coloration.
