    The percentage of food waste has due to the fact that companies do not correctly use the entire product. Consequently, research has been carried out in order to take advantage of these waste, highlighting naranjilla for its high nutritional content, particularly carotenoids, a bioactive compound with antioxidant and anti-inflammatory properties capable of preventing various diseases. In the present study, carotenoid extraction was performed out at different plant material/solvent ratios and extraction times. A statistical analysis was then applied to optimize the two factors, obtaining a concentration of 2,287 mg per liter. Next, it was microencapsulated with a polymeric combination of gum arabic and maltodextrin. Subsequently, the microencapsulation efficiency was evaluated qualitatively by FT-IR and quantitatively with 91,74 percent efficiency. The antioxidant activity was determined using the DPPH method, achieving an inhibition percentage of 63,00 and 49,52 for the extract and the microencapsulate, respectively. Finally, the anti-inflammatory capacity was evaluated with an inhibition percentage of 56,42 for the extract and 41,42 in the microencapsulated. The results obtained indicate that the higher the concentration of carotenoids in the sample, the better results will be achieved. Therefore, the purpose of this study is to take advantage of the residues of naranjilla with a high content of carotenoids with antioxidant and anti-inflammatory properties that can be used in new products of industrial interest.
