Pequi (Caryocar) pulp, the most consumed component of pequi fruit, is one of the richest Brazilian carotenoid sources, and the most important carotenoid food source native to the Cerrado. However, there are considerable differences among pequi species regarding total carotenoids content and carotenoids profile. Caryocar brasiliense Camb. pulp presents higher content of total carotenoids than Caryocar villosum (Aubl.) Pers. Regarding the carotenoids profile, few studies are available in the literature, mainly with C. brasiliense. Pequi pulp also has high contents of lipids, dietary fiber, zinc, and magnesium, and is source of calcium and polyphenols. Pequi almond presents high energy, lipid, protein, dietary fiber, and ash contents. Pequi oil (pulp and almond) has high levels of monounsaturated fatty acids, especially oleic acid, and relatively high contents of saturated fatty acids, mainly palmitic. Pequi shell (exocarp and external mesocarp) is the largest component of the fruit and a solid residue of the pequi processing, which is rich in dietary fibers, including soluble fibers, and phenolic compounds, mostly gallic acid, ellagic acid, and quercetin. Pulp oil is the pequi byproduct most investigated in in vivo studies. Research with pequi pulp oil in animal models has shown antioxidant, anti-inflammatory, cardioprotective, hepatoprotective, antigenotoxic, and anticarcinogenic effects. In humans, there are evidences supporting anti-inflammatory, cardioprotective, and antigenotoxic effects. Studies on carotenoids profile of pequi pulp in different fruit species are recommended, and in vivo studies are necessary to better explore the potential health benefits of pequi fruit components, mainly the pequi pulp and shell.
