Description:	The demand for pecan consumption has been increasing, and consequently, the volume of waste generated from shelling and processing for pecan oil extraction has also grown. This study aimed to characterize the residues resulting from the oil extraction process of the Barton cultivar. For this purpose, pecans from commercial orchards were shelled for oil extraction via pressing. The shells and the cake resulting from the oil extraction were collected. Both the shells and cake were evaluated for their proximal composition and bioactive compounds. The cake showed a composition of 18.62% protein and 17.42% lipids, with a fatty acid profile similar to pecan kernels. The shells stood out for their total phenolic content and antioxidant capacity, as well as their fiber content (36.50%). The valorization of these byproducts is essential as they have potential for use in the food industry and for the development of new products. This study contributes to a more sustainable and economically viable production chain while encouraging the exploration of pecan byproducts, which have an excellent nutritional profile and high added value, expanding market opportunities.
