They contained around 10% free monosaccharides and low HMF, despite the fact that the fruit had
been cooked. The fractions of hemicellulose were composed mainly of arabinose and xylose. Polyphenolic contents were in the same order as in many fruit species, whereas soluble phenolicacids were not detected. The lyophilized and ground residues exhibited high WHCs and average oHcs: the color of the dry and ground samples was light brownish, with a more reddish color for the date residue. The characteristics of these by-products from cooked fruit may offer interesting prospects for food products. For example, DF concentrates with significant antioxidant properties could be obtained after eliminating the free monosaccharides (by washing the dry and ground residues). The fact that the by-products came from cooked fruit implies that they contain specific aromas (notably caramelized sugar) and sensory characteristics. Therefore any application would require a compatibility with the food products (jams, spreads and cookies should be suitable) or could possibly even provide an improvement of a product's sensory characteristics: in any case these would be rather niche applications.
