Characterization of the Industrial Residues of Seven Fruits and Prospection of Their Potential Application as Food Supplements

Abstract

Seven residues from tropical fruit (acerola, cashew apple, guava, mango, papaya, pineapple, and sapota) processing were prospected for physicochemical parameters (pH, total soluble solids, water activity, reducing sugar, acidity, protein, moisture, ash, and lipids), functional compounds (total phenolic content, anthocyanins, ascorbic acid, and free radical scavenging activity-DPPH), fatty acid profile, and mineral content. Prospection of these industrial residues aimed its use as potential sources for food supplementation. Acerola residue was found to be a valuable source of anthocyanins, phenolics, and vitamin C; cashew apple residue could be a source of unsaturated fatty acids; pineapple and papaya residues could be used, respectively, as manganese and phosphorous source.

Potential prebiotic properties of cashew apple (Anacardium occidentale L.) agro‐industrial byproduct on Lactobacillus species

“…Overall, the insoluble (277.2 g kg −1 ) and soluble (74.3 g kg −1 ) fibers and fructans (15.4 g kg −1 ) that were detected in the studied CAP (Table ) are potential metabolic substrates for the establishment of the confirmed prebiotic effects because the components of dietary fiber and fructans are resistant to digestion and absorption in the human small intestine; when these substrates reach the colon, they are selectively fermented by the beneficial bacteria comprising the intestinal flora . The presence of monosaccharides in CAP, such as glucose, fructose and maltose, even in small amounts, may also potentiate the use of CAP as a direct fermentable substrate by probiotic bacteria …”

“…However, the cashew nut represents approximately 10% of the total fruit weight, and only 20% of the produced cashew apples are processed for the production of juice, frozen pulp and jam. The remaining of this production is commonly disposed of in the environment as agro‐industrial byproducts …”

“…The byproducts that are generated from the agro‐industrial processing of cashew apples comprise mainly mashed flesh and peels and represent approximately 20% of the apple total weight . Some studies have investigated these byproducts as a source of bioactive phytochemicals, particularly those with recognized antioxidant properties . Prebiotic components (e.g.…”
