For certain food applications, it may be advantageous for TDF concentrates to have balanced contents of soluble (SDF) and insoluble(IDF) fractions. In the case of the exotic fruit analysed here, only mango and passion fruit showed similar levels (p < 0.05) with IDF/SDF ratios of 1.5:1 and 1.3:1, respectively, as recommended by Spiller (1986), who indicated that the ratio should be in the range of 1.0–2.3 in order to obtain the physiological effects associated with both soluble and insoluble fractions. Pineapple showed the greatest difference between IDF and SDF content with an IDF/SDF ratio of 120:1.
