“…Operations such as back flushing and pulsing, and use of non-conventional technologies (pulsed electric fields and ultrasound) have been reported to improve cleaning and even mass transport in UF [ 1 ]. The application of electric fields with NaCl was able to completely clean a zirconium dioxide/titanium dioxide UF membrane of 15 kg mol −1 MWCO fouled with whey model solutions [ 34 ]. Ultrasound technology has been used to enhance permeate flux.…”

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.

“…However, membrane fouling caused by long‐term membrane filtration operations causes a substantial problem in membrane recovery. There are some methods that can reduce protein fouling such as diafiltration (Hartinger & Kulozik, 2020), ultrasound (Aghapour Aktij et al., 2020), and electric field (Corbatón‐Báguena et al., 2016) and magnetic field treatments (Kyle, 2006). Reducing the diafiltration steps were also important (Hartinger & Kulozik, 2020).…”

In this study, enzymatic cross‐linked whey protein coupling ultrafiltration was used to reduce membrane fouling and increase whey protein recovery rate. The filtration efficiency and protein interaction with the membrane surface were investigated. The results showed that the protein recovery rate and relative flux of transglutaminase catalysis protein followed by tyrosinase each increased by approximately 30% during ultrafiltration. The total membrane resistance was reduced by approximately 20%. The shape of the transglutaminase and tyrosinase cross‐linked protein had somewhat spherical and cylindrical structure similar to an elongated shape based on fluorescence microscopy imaging, which indicated membrane resistance reduction. Fluorescence excitation–emission matrix spectroscopy (EEM) showed that the permeation peak intensities of transglutaminase followed by tyrosinase catalysis protein decreased sharply in the tryptophan and aromatic‐like protein fields, indicating that most protein was rejected after ultrafiltration. The repulsive interaction energy was increased between the cross‐linked proteins and membrane based on extended Derjaguin–Landau–Verwey–Overbeek (XDLVO) analysis.

“…[20,21] Unconventional approaches to membrane cleaning techniques include electric fields. [22][23][24] These methods do not depend on chemicals and have the ability to be performed during the running filtration process without alterations to the applied pressure or chemical composition of the filtrate. As most particles in a liquid carry an electric charge, electric fields offer the possibility to affect a large variety of particles through electrostatic repulsion and electrophoretic force.…”

Application of electric fields as a mechanism against membrane fouling is an emerging cleaning process for membranes. Sintering of ultrahigh molecular weight polyethylene powder particles decorated with multiwalled carbon nanotubes (MWCNT) is performed to produce electrically conductive porous filtration membranes. The contact of the molten particle surfaces leads to their fusion through neck formation during sintering. As the MWCNT only cover the surface of the powder particles, they form a conductive network with a high number of inter‐MWCNT contacts in pathways through the polymer matrix. Membranes with an electrical conductivity of 0.9 S m−1 at a MWCNT concentration of 5.0 wt% are prepared. Additionally, a comparison of sintered and compression molded samples shows that after the heating interval, crystallization during cooling strongly influences the formation of the MWCNT network. The study reveals that electrically conductive, porous polymer membranes for microfiltration applications can be prepared using a solvent‐free process.
