Different agri-food wastes (brewer´s spent grain (BSG), coffee ground (SCG) and kale stems) have been proposed as excellent sources of protein-enriched extracts with an antioxidant capacity. The optimization the microwave-assisted hydrothermal alkali extraction has compared in this study. From a technical economic point view, BSG under optimal conditions (110 ºC, 10 min 0.5 M NaOH) provided best extract content 14.6 kg protein/100 (dry matter), 13.8 g/L total sugars activity (DPPH method)...
Rhamnogalacturonan–I (RG–I) pectin recovered from sugar beet pulp (SBP) and discarded red beetroot (DRB) were subjected to enzymatic hydrolysis obtain pectooligosaccharides (POS). The hydrolysates with the highest amount of oligomer a degree polymerization 2 6 selected for detailed characterization composition structure by MALDI-TOF MS 1H NMR. yields POS products ranged 32.7% (g DRB POS/g DRB) 37.0% SBP Pectin/g SBP) content 64.4% (DRB products) 68.7% (SBP POS).

Abstract BACKGROUND Deep eutectic solvents (DESs) have been tested as promising green for the microwave‐assisted extraction of phenolic compounds from brewer's spent grain (BSG). Firstly, a preliminary screening with four different DESs was carried out in order to determine most effective DES recovering (measured total phenols) BSG. Later, an experimental design using found be applied optimize choline chloride (ChCl):glycerol extraction. RESULTS ChCl:glycerol recover (2.3 mg GA g −1 BSG),...
The complete valorisation of sugar beet pulp (SBP) through pectooligosaccharides (POS) extraction and biobutanol production was studied. A central composite experimental design planned to optimise the time temperature hydrothermal microwave-assisted extraction. 59.7% POS present in SBP were recovered, a prehydrolysate with 31.1 g POS/L obtained under optimal conditions (165 °C 12 min). further precipitated by ethanol. One-step stepwise alcohol precipitation evaluated. prehydrolysate:ethanol...
Discarded red beetroot (DRB) is an organic waste generated in the food industry. This study focused on valorization of DRB through recovery bioactive compounds. The characterization juice confirmed a higher content antioxidants (DPPH 504 ± 24 μmol TE/L, FRAP 10920 440 ABTS 22012 592 TE/L), phenolic compounds (1789 56 mg GAE/L), flavonoids (471 17 CE/L) and betalains (1426 mg/L) than commercial juices. pomace contains pectin that was recovered by microwave extraction aided surfactant...
To recover industrial pectin from sugar beet pulp (SBP), a combined surfactant and ultrasound-assisted extraction, followed by concentration with ultrafiltration/diafiltration membranes is proposed. First, the operation conditions of extraction were optimized for synthetic (Tween80, PEG4000) natural (Saponin) surfactants. Tween 80 Saponin provided maximum galacturonic acid (GalA) concentrations (5.5 5.8 g/L, respectively) under best (4 gsurfactant/L, pH = 1, amplitude 90%, time 90 min). The...
The use of mineral fertilizers in agriculture has significantly increased to support the growing global food demand. Organic are produced from renewable waste materials overcome drawbacks inorganic fertilizers. development novel production processes organic entails a significant advance towards circular economy that reincorporates into cycle. In this work, economic and environmental feasibility an industrial plant with treatment capacity 300 kg/h for liquid been performed. Two extraction...
This study evaluates different fermentation strategies to produce 2,3-butanediol (2,3-BD) from banana industry waste, such as whole bananas (fruit + peels) and peels, selecting the most favorable a technical economic point of view. Both residues have enough free sugars (17.8 %–35.8 %), glucan (11.0 %–14.2 %) hemicellulose (2.8 %–6.3 be promising substrates for 2,3-BD fermentation. Saccharification was studied by comparing enzymatic hydrolysis, hydrothermal pretreatment, pretreatment followed...
