Energy and lipid contents, and polyphenols composition of pequi pulp according to the fruit native area

Abstract

ABSTRACT: Pequi (Caryocar spp.) is a fruit native to the Brazilian Savannah (Cerrado), and Caryocar brasilienseCamb. is one of the most prevalent species in this biome. The consumption of the pequi pulp has been associated with health benefits, such as antioxidant, anti-inflammatory, hypolipidemic, hepatoprotective, and anticarcinogenic effects. These benefits have been attributed to its high density in nutrients and bioactive compounds. However, there is evidence about considerable variation in the nutritional profile among pequi pulps of different species, and among pulps of the same species, but from different areas of the Cerrado. In addition, there is no information in literature regarding the polyphenols profile of C. brasiliense pulp, neither about the influence of the native area of the fruit on the composition of these phytochemicals. So, this study analyzed the nutrient composition and identified the phenolic compounds in the pulp of C. brasiliense fruits native to four different areas of the Cerrado. There was a remarkable variation in the contents of energy (176.3-387.2 kcal/100 g) and lipids (13.0-37.5 g/100 g) among samples. In contrast, no difference was observed in the polyphenols composition, since gallic acid, protocatechuic acid, catechin, epicatechin, p-coumaric acid, and ellagic acid were identified in all pequi pulps. C. brasiliense pulp shows potential to be used as a functional ingredient rich in bioactive compounds, but with different contents of energy and lipids according to the fruit’s native area to attempt distinct health allegations of the product.
