“…at low concentrations and pH = 5.5), ILTPP can also be seen as an alternative to overcome the limitations that other protein concentration techniques present for the production of whey protein concentrates (WPC) or isolates (WPI). For instance, the first steps in the production of both WPC and WPI are usually based on membrane processes, but the maximum protein concentration that can be obtained by means of these techniques is 20% …”

“…For instance, the first steps in the production of both WPC and WPI are usually based on membrane processes, but the maximum protein concentration that can be obtained by means of these techniques is 20%. 41,42 Although ILTPP is considered a promising alternative for the mentioned applications, the recyclability of the ionic liquid used in the process must also be studied to minimize the economic and environmental impacts associated with these compounds. For this purpose, there are several approaches, such as the use of salt to increase the concentration of ionic liquid in the ionic liquid-rich phase, 43 extraction of the ionic liquid with other solvents 21,31 or, at least, enhancement of its purity by means of water removal by flash distillation or by stripping.…”

BACKGROUND The ionic liquid three phase partitioning (ILTPP) technique is a promising alternative to conventional processing technologies for protein separation and purification since it allows protein recovery at the liquid–liquid interface. In previous work, ILTPP has been developed with the BmimBF4/NaH2PO4 system for lactoferrin recovery, a bovine whey protein with important nutraceutical properties. However, BmimBF4 may suffer from hydrolysis when it is in contact with water, so the selection of an alternative ionic liquid with similar results regarding lactoferrin recovery should be sought. RESULTS The system based on BmimTfO and phosphate is selected as the most suitable since it combines relatively high LF recoveries at the liquid–liquid interface (83–99%) and chemical stability. The highest LF recoveries occur at moderate acidic pH (3.1–4.0), which may also be improved at relatively low protein concentrations. The process selectivity with respect to bovine serum albumin (another whey protein) varies from 1.1 to 3.0, depending on experimental conditions. CONCLUSION ILTPP is a promising technique to recover the protein fraction from bovine whey or to enrich specific proteins such as lactoferrin, so ILTPP could replace alternative techniques such as membranes. The risk of hydrolysis associated with previous ionic liquid ILTPP systems has been successfully overcome. © 2014 Society of Chemical Industry

“…Of soy protein hydrolysate generated by consecutive pepsin and pancreatin treatment and following fractionation by hollow fiber and spiralwound membrane with the same 10 kDa MWCO, there are four intriguing phenomena: (1) longer UF time of hollow fiber (3 h) led to higher content of glycine, threonine, valine, methionine, and isoleucine in permeate, representing smaller peptide as opposed to spiralwound (10 min); (2) primary aromatic amino acids (tyrosine, leucine, and phenylalanine) produced by pancreatin (chymotrypsin) activity shows similar concentration in permeate of both membrane module; (3) amino acids constituting both low and high molecular-weight peptides, such as aspartic acid, serine, histidine, alanine, proline, arginine, and cysteine, have similar concentration in permeate and initial hydrolysate; and (4) highly retained amino acids (glutamic acid and lysine), which belong to high molecular-weight peptides, are more concentrated in the permeate of hollow fiber compared to spiral-wound. Yet, slightly higher antioxidative (ORAC assays) and antiviral activity (PFU assays) was found in the use of hollow fiber configuration [175].…”

“…However, they demonstrated that rejection coefficients of proteins, fat, and lactose are not a function of temperature, pressure, and fluid velocity [216]. So, levelling the temperature up to 70 • C will still increase the permeate flux owing to the facilitation of mass transport by lower viscosity [175].…”

Recent Advancements of UF-Based Separation for Selective Enrichment of Proteins and Bioactive Peptides—A Review

Proteins are one of the primary building blocks that have significant functional properties to be applied in food and pharmaceutical industries. Proteins could be beneficial in their concentrated products or isolates, of which membrane-based filtration methods such as ultrafiltration (UF) encompass application in broad spectra of protein sources. More importantly, selective enrichment by UF is of immense interest due to the presence of antinutrients that may dominate their perspicuous bioactivities. UF process is primarily obstructed by concentration polarization and fouling; in turn, a trade-off between productivity and selectivity emerges, especially when pure isolates are an ultimate goal. Several factors such as operating conditions and membrane equipment could leverage those pervasive contributions; therefore, UF protocols should be optimized for each unique protein mixture and mode of configuration. For instance, employing charged UF membranes or combining UF membranes with electrodialysis enables efficient separation of proteins with a similar molecular weight, which is hard to achieve by the conventional UF membrane. Meanwhile, some proposed strategies, such as utilizing ultrasonic waves, tuning operating conditions, and modifying membrane surfaces, can effectively mitigate fouling issues. A plethora of advancements in UF, from their membrane material modification to the arrangement of new configurations, contribute to the quest to actualize promising potentials of protein separation by UF, and they are reviewed in this paper.

“…The defatted and pasteurized CW can then be subjected to microfiltration to retain the bacteria debris, before proceeding to the separation of the proteins, lactose, and mineral salts [41]. Membrane filtration has been used to isolate the whey proteins, mineral salts, and water present in CW [38,[42][43][44]. In this sense, ultrafiltration membranes can be suitable to isolate whey proteins, while nano-filters can separate the remaining lactose and mineral salts.…”

Organic acids constitute a group of organic compounds that find multiple applications in the food, cosmetic, pharmaceutical, and chemical industries. For this reason, the market for these products is continuously growing. Traditionally, most organic acids have been produced by chemical synthesis from oil derivatives. However, the irreversible depletion of oil has led us to pay attention to other primary sources as possible raw materials to produce organic acids. The microbial production of organic acids from lactose could be a valid, economical, and sustainable alternative to guarantee the sustained demand for organic acids. Considering that lactose is a by-product of the dairy industry, this review describes different procedures to obtain organic acids from lactose by using microbial bioprocesses.
