Color exerts great influence in everyday life, this being the first contact that has the consumer with products. Despite the imposing and frequent use of artificial dyes in different products that offers the food industry, and although these colorings are permitted in only some countries is important to highlight the harmful effects that bring health as According to studies they produce effects such as allergies, cancer, hyperactivity and in children, including attention-deficit. Contrary to the dye obtained from Peel papaya that has any adverse effects to the health of consumers, and which contributes to reducing the environmental impact from the generation of this type of waste, since one of the most serious problems in landfills are leachate produced fruit waste and odour generated.
The proposal's business is the production of a natural colorant obtained from papaya residues, in order to propose their use in the food industry, which is expected to have impact initially in this industry since in Peel papaya molecules of commercial interest such as carotenoids, functional compounds that act as antioxidants and natural pigments that have pro vitamin A activity can be obtained.
For the development and fulfilment of the objectives was an extraction solid - liquid in Soxhlet equipment of the Β -carotene of Peel papaya previously selected, clean and reduced, using as solvent ethanol, and separating the resin obtained through distillation (β- carotene), which is characterized in a spectrophotometer from UV/VIS absorption. Colouring is obtained after a drying process according to formulation, on a machine Spray-Dried, powdered finally retrieved coloring is subjected to a process of stabilization to conditions of environment, cooling and camera in order to study the variations in color over time making the ultimate use of the dye for the application.
