Physicochemical attributes and functional properties of flowers of Brazilian feijoa genotypes

Abstract: The objective of this work was to characterize entire flowers of the feijoa (Acca sellowiana) genotypes 'Alcântara', 'Helena', 'Mattos', 'Nonante', and the accession 2316 for dry matter, total antioxidant activity (TAA), and the contents of soluble solids, ascorbic acid, total anthocyanins, total flavonoids, and total phenolic compounds (TPC), as well as for the petal surface areas and colors. The TAA was quantified by the ABTS and DPPH methods. Flowers of the accession 2316 and of the cultivars Alcântara and Helena showed the highest contents of anthocyanins and flavonoids, as well as the highest values of TPC and TAA. The feijoa genotypes cultivated in Southern Brazil show high contents of soluble solids and represent a natural source of antioxidants.
