Xique-xique, a cactus found in the Caatinga biome, is rich in nutritional value and bioactive compounds, making it a potential food alternative with various uses and potential for enrichment in different food products.
Xique-xique (Pilosocereus gounellei) is a cactus found in the Caatinga biome which is used in folk medicine for treating inflammation, and also used in animal food. This study evaluated its proximate composition and bioactive compounds, as well as its bioaccessibility and antioxidant activity. Experiments were performed on different parts of the plant. The central stem of the xique-xique can be considered a source of insoluble dietary fiber (5.18 g/100 g) and soluble fiber (1.37 g/100 g). The vascular cylinder contained the highest mineral content: K (308.4 mg/100 g), Ca (145.57 mg/100 g), Mg (182.40 mg/100 g), and Mn (7.71 mg/100 g). The vascular cylinder group presented the highest activity for capturing DPPH radicals (572.96 mu M of TEAC/100 g) and ferric reducing ability (1912.95 mu M of TEAC/100 g). Catechin and epigallocatechin-gallate were the major phenolic compounds, while catechin, epigallocatechin gallate and procyanidin B and gallic acid were the most bioaccessible compounds after in vitro gastrointestinal digestion. Xique-xique can be considered as a potential food alternative with nutritional value and bioactive compounds, indicating its potential use and enrichment in various food products.
