Physical-chemical characterization of fruit of three types of soursop trees (Annona muricata L.)

Soursop fruit of types 'Morada', 'Lisa' and 'Comum' produced in the South of the state of Bahia, Brazil, were evaluated as to physical and chemical characteristics. It wasn't detected mean weight differences among the types 'Morada' (3,21kg), 'Lisa' (2,82kg) and 'Comum' (2,39kg). Fruits of 'Lisa' presented higher pulp percentage (85,85%) in relation to 'Morada' (83,57%) and 'Comum' (83,12%). The minor ratio among length and diameter observed on fruits types 'Morada' and 'Lisa', characterize them as cordiforme shape. Except the bigger value of total soluble sugars presented by 'Lisa' fruit (14,55g/100g), it was not significant the difference among soursop fruit types in respect to their chemical characteristics evaluated. which presented the following averages: ºBrix 13,11; acidity 0,94 g/100g, pH 3,46 and vitamin C 37,25mg/100g. These values, except the pH, overcame the minimum values established in the Pattern of Identity and Quality of the Ministry of Agriculture, for soursop pulp.
