In the context of preserving and improving human health, electrodialytic processes are very promising perspectives. Indeed, they allow the treatment of water, preservation of food products, production of bioactive compounds, extraction of organic acids, and recovery of energy from natural and wastewaters without major environmental impact. Hence, the aim of the present review is to give a global portrait of the most recent developments in electrodialytic membrane phenomena and their uses in sustainable strategies. It has appeared that new knowledge on pulsed electric fields, electroconvective vortices, overlimiting conditions and reversal modes as well as recent demonstrations of their applications are currently boosting the interest for electrodialytic processes. However, the hurdles are still high when dealing with scale-ups and real-life conditions. Furthermore, looking at the recent research trends, potable water and wastewater treatment as well as the production of value-added bioactive products in a circular economy will probably be the main applications to be developed and improved. All these processes, taking into account their principles and specificities, can be used for specific eco-efficient applications. However, to prove the sustainability of such process strategies, more life cycle assessments will be necessary to convince people of the merits of coupling these technologies.

“…Bovine hemoglobin is known to be a source of peptides presenting biological activities [4]. This protein is the source of many peptides whose antimicrobial, antioxidant, antihypertensive, opioid bacterial growth stimulant, hematopoietic activities have been described in the literature [5][6][7][8][9][10][11][12][13][14][15][16].…”

The porcine cruor represents a co-product from slaughterhouses. It mainly contains hemoglobin which is rich in bioactive peptides obtained by hydrolysis by porcine pepsin. The aim of this study is to valorize this new source rich of bioactive peptides to be used as feed additives. An in silico study on the potential of porcine cruor to contain bioactive peptides was studied by comparing it with peptides derived from bovine hemoglobin. The blast results showed a high similarity between porcine cruor hydrolysate peptides and bovine hemoglobin hydrolysates for both α and β chains with identities of 87% and 83% respectively. Cleavage sites of porcine cruor were also predicted using Peptide Cutter software and compared with bovine hemoglobin. Results reveal the preservation of most of peptides of porcine cruor hydrolysates comparing to bovine hemoglobin hydrolysates. The presence of bioactive peptides was then determined by mass spectrometry analysis. Results showed the presence of 37 bioactive peptides defined by their sequences found in previous study with mainly antibacterial and opioid peptides. The antibacterial activity was then verified by in vitro analysis against 4 bacterial strains. Results showed interesting MIC values comparing with tested synthetic peptides (4.53 µM for M.luteus and L.innocua, 35.94 µM for E.coli and 312 µM for S.newport). The antioxidant activity was also verified by studying DPPH•+ trapping and results showed an antiradical activity for porcine cruor hydrolysate greater than neokyotorphin which was previously validated as a natural preservative to substitute synthetic additives against food alteration (14% and 10% respectively). These similarities of porcine cruor hydrolysate in peptic profiles as well as biological activities make it a new interesting source of bioactive peptides.

“…When porous membranes are employed in EDUF, they act as electrophoretic membrane contactors, in which separation occurs while taking into account charge and molecular weight peptide differences. This technology has been reported as a very selective one, capable of separating targeted peptides from complex mixtures and residues from food and agro by-products [44][45][46]. The simultaneous separation of anionic and cationic peptides from a herring milt hydrolysate by EDUF using UF membranes of 50 and 20 kg mol −1 MWCO was reported [45].…”

“…The sustainable aspect of EDUF was explored in the valorization of the bovine cruor, i.e., the red cells fraction of the blood by-product from slaughterhouse processing. A positively charged antimicrobial peptide, obtained from hemoglobin, was enriched 24-fold using a 10 kg mol −1 MWCO membrane [44]. Associated costs of producing peptides from EDUF technologies was reported to range from 0.3 to 0.5 Canadian dollars per gram of peptides for an effective filtration area of 10 m 2 [47].…”

Membrane Fractionation of Protein Hydrolysates from By-Products: Recovery of Valuable Compounds from Spent Yeasts

Spent brewer’s yeast (Saccharomyces sp.), the second most generated by-product from the brewing industry, contains bioactive and nutritional compounds with high added value such as proteins (40–50%), polysaccharides, fibers and vitamins. Molecules of interest from agro-industrial by-products need to be extracted, separated, concentrated, and/or purified so that a minimum purity level is achieved, allowing its application. Enzymatic hydrolysis has been successfully used in the production of peptides and protein hydrolysates. The obtained hydrolysates require efficient downstream processes such as membrane technology, which is an important tool for the recovery of thermolabile and sensitive compounds from complex mixtures, with low energy consumption and high specificity. The integration of membrane techniques that promote the separation through sieving and charge-based mechanisms is of great interest to improve the purity of the recovered fractions. This review is specifically addressed to the application of membrane technologies for the recovery of peptides from yeast protein hydrolysates. Fundamental concepts and practical aspects relative to the ultrafiltration of agro-industrial protein hydrolysates will be described. Challenges and perspectives involving the recovery of peptides from yeast protein hydrolysates will be presented and thoroughly discussed.
