Provenient residues from industrial processing of açaí berries (Euterpe precatoria Mart): nutritional and antinutritional contents, phenolic profile, and pigments

Abstract

Materials and methods Materials and reagentsWhole fruits from Euterpe precatória and dreg and seed (residues from processing) were donated by the FastAçai ® Brazilian company. The whole fruits were analyzed for morphology, such as mass, transversal diameter, and length. The peel+pulp (PP) was obtained by manual pulping without the use of maceration to preserve nutrients and bioactive compounds. The dreg (FD) and the fresh seed (FSE) were divided into three lots: one lot for analysis of soluble solids, pH, acidity, and color; the second

Exotic fruits patents trends: An overview based on technological prospection with a focus on Amazonian

“…For example, in the case of rambutan, there is a great nutritional and functional potential of the seeds, making it a potential fruit for applications in the food, pharmaceutical, and cosmetic industries [ 90 ]. The study by Alves et al [ 105 ] demonstrated that the co-products from the açaí pulp can be an important source of fiber and antioxidant compounds. In addition, Santos et al [ 106 ] pointed out that the bacaba powder obtained through a freeze-drying technique has a wide concentration of antioxidant components with bioactive properties, which allows its application in different industrial sectors.…”
