“…For BAB and BSG, all treatments increased the flavonoid content compared with the AQ extraction, with the CE hydrolysates having ones with the highest concentrations of 10.0 and 5.2 mg RE/g residue , respectively. The flavonoid content of BAB CE hydrolysate is within the range of the concentration reported for other agave species [55,56]. Regarding BSG, CE hydrolysate flavonoid content was higher than the one reported after chemical hydrolysis [40] and solvent extraction [44] of this residue.…”

Agro-industrial wastes can be used to obtain high-value compounds rich in antioxidant and antimicrobial activity. This study aimed to compare different extraction techniques for the recovery of sugars, antioxidants, and antimicrobial compounds from brewer’s spent grain (BSG), blue agave bagasse (BAB), spoiled blackberries (BB), and raspberries (RB). Aqueous (AQ), enzymatic (E), chemical-enzymatic (CE), and hydroalcoholic (EOH) extractions were assessed, and sugars, phenolics, flavonoids, and anthocyanin contents were quantified. Antioxidant activity of the extracts was evaluated using the ABTS and DPPH assays, and antimicrobial activity was tested against three yeasts and six bacteria. The CE process gave the highest total and reducing sugars content for the four residues tested, and the highest antioxidant activity, phenolics, flavonoids and anthocyanin content for BAB and BSG. Regarding BB and RB, the best treatment to obtain total and reducing sugars and antioxidant activity with ABTS was CE; the highest content of anthocyanins, phenolic, flavonoids and antioxidant activity with DPPH was obtained with EOH treatment. CE extracts of BSG and RB showed the highest inhibition against the strains studied. Results show that BSG, BB, and RB can be a source of antioxidants and antimicrobial compounds for the food and pharmaceutical industries. Depending on the desired application and component of interest, one of the extraction techniques evaluated here could be used.

This work aimed at evaluating the prebiotic potential of the aqueous extract and crude polysaccharides from Agave sisalana boles by an in vitro screening. Crude polysaccharides were obtained from the aqueous bole extract by precipitation with acetone and re-suspended in water. The liquid extract and the polysaccharide solution were then spray dried and submitted to thermal analysis and quantification of metabolites. Prebiotic activity was checked on probiotic strains belonging to the Lactobacillus genus using inulin, fructo-oligosaccharides, fructose and glucose as positive controls. The powder of A. sisalana bole extract, which has recently been identified as a rich source of inulin, exhibited higher potential of fermentation compared with crude polysaccharides.
