With respect to dietary fibre content, the co-products obtained from those tropical exotic fruits used in this study showed (p < 0.05) TDF contents ranging from 69.1 to 81.5 g/100 g on a dry matter basis. The TDF in all samples analysed was similar to those reported for other tropical fruits, such as pomegranate peel co-product (72.7%, dry sample), in fibre from Mexican lime peels (70.4 g/100 g dry sample)or açai pulp (71.2% dry sample), and higher than those reported for some other fruits; for example, a fibre-rich cocoa product (60.5 g/100 g) or coconut fibre (60.9 g/100 g dry sample). In all cases, the IDF fraction was higher than the SDF fraction.Pineapple showed the highest (p < 0.05) IDF content, followed(p < 0.05) by guava, passion fruit and mango. This large amount of IDF present in exotic fruit co-products is an indicator of the considerable amounts of celluloses and hemicelluloses present. A high proportion of IDF in the exotic fruit co-products could be considered an advantage because IDF can be used by the food industry as an ingredient to increase the content of indigestible insoluble compounds . In addition, a high IDF content could have beneficial้ health effects related to increases in satiety and in the volume and
weight of faecal mass, thus promoting improved functioning of the digestive system.
