Soursops were harvested using the disc collection method proposed by Livera (1992), and the following physical characteristics were observed:
The soursops were analysed by AOAC methods (AOAC, 2006) with respect to the following physical and chemical parameters: moisture, ash, protein, lipid, total dietary fiber and insoluble dietary fiber content.
The results of the chemical composition analysis of soursops are similar to those described by Sousa et al.
05) in soluble fibre composition (Table 1), among mature soursops or between soursops in the physiological maturity.
The total dietary fibre found in soursops in the current study was equivalent to that found by Guerra et al.
Soursops are also considered an important source of functional compounds such as phenolic compounds.
The level of EPPs in the methanol extract of soursop pulp found in this study was almost two times higher than reported by other authors in soursop pulp, who have reported values from 1.
With the use of emerging methods in combination con solvents it is possible to obtain a significant polyphenols and identified acetogenins from soursop pulp.
