In the present investigation, a process of extraction and stabilization of the anthocyanines, the natural dye in jambolan fruit (Syzygium cumini (L). Skeels) was developed to be used in the manufacture of a shampoo as a substitute for artificial colorants. Initially jambolan fruits were collected, frozen, lyophilized, and cold macerated using a solvent mixture: (95% ethanol:0.1 N hydrochloric acid 85:15). 20% of dye was extracted and its concentration was 1,865 ppm and its total monomeric anthocyanin was 43mg cy-3-gly/100 g fresh weight. Then, the accelerated stability of the extracts was evaluated at 33 °C and 50 °C and pH=3 and pH=4, of both the natural colorant and Red No. 40. The anthocyanin were more stable at pH=3 than at pH=4 and at 33° C than at 50 °C and at the latter temperature red 40 is more stable. Subsequently, a shampoo with the addition of the extracted dye was developed, showing that it can be used as a substitute for artificial colorant. Finally, the finished product was characterized by physicochemical tests, according to COVENIN standards.
