“…Nevertheless, the cost and environmental impact of the above-mentioned processes are tremendous and mostly attributed to the use of ion-exchange resin [ 7 ]. Hence, in the recent years, a number of studies were published regarding acid whey processing by optimizing either nanofiltration [ 8 , 9 ] or ED processes [ 10 , 11 ], trying to provide better cost-effective and eco-efficient alternatives. So far, ED processes allowed for reaching suitable deacidification (44%) and demineralization (67%) rates that have been reported as sufficient for the acid whey to be spray-dried while obtaining powders of acceptable quality [ 9 ].…”

However, whatever the configuration or parameters used, these ED processes were subject to major scaling (mineral fouling) on membrane surfaces [ 11 ], making the transposition of ED alone, or without pretreatments, impossible at an industrial scale.…”

The drying of acid whey is hindered by its high mineral and organic acid contents, and their removal is performed industrially through expensive and environmentally impacting serial processes. Previous works demonstrated the ability to remove these elements by electrodialysis alone but with a major concern—membrane scaling. In this study, two conditions of pulsed electric field (PEF) were tested and compared to conventional DC current condition to evaluate the potential of PEF to mitigate membrane scaling and to affect lactic acid and salt removals. The application of a PEF 25 s/25 s pulse/pause combination at an initial under-limiting current density allowed for decreasing the amount of scaling, the final system electrical resistance by 32%, and the relative energy consumption up to 33%. The use of pulsed current also enabled better lactic acid removal than the DC condition by 10% and 16% for PEF 50 s/10 s and 25 s/25 s, respectively. These results would be due to two mechanisms: (1) the mitigation of concentration polarization phenomenon and (2) the rinsing of the membranes during the pause periods. To the best of our knowledge, this was the first time that PEF current conditions were used on acid whey to both demineralize and deacidify it.

“…Methods such as diffusion dialysis, solvent extraction, distillation, membrane extraction of liquid surfactant, adsorption, chromatographic methods, ultrafiltration, reverse osmosis, drying, conventional electrodialysis, and microfiltration have been used. [88][89][90][91] Although some methods are cheaper and more effective than electrodialysis or adsorption, it is these last two that offer a better balance between effectiveness and cost. 92,93 Bioactive peptides production…”

In Mexico, whey is discarded into drains without treatment, which represents an environmental problem. It is known that whey is a mixture of nutrients that increase biochemical demand (BOD) and chemical oxygen demand (COD), exceeding the limits established by national and international standards. Some uses of whey have been proposed to reduce the negative impact it produces on the environment. Some of these uses are the production of high‐value raw materials, separation of macromolecules of industrial interest, and the generation of energy, among others. The integral use of waste under a biorefinery scheme represents a viable alternative for the use of this waste. In this way, the chemical composition of the waste can be used to recover compounds with high added value. The main objective of this review is to propose a dairy whey biorefinery to use components of commercial interest. This biorefinery process involves three stages: the first is the separation of lactoferrin using a polyacrylamide matrix (PAM) impregnated with copper; the second is lactic fermentation using the residue resulting from the separation of lactoferrin, from which lactic acid, hydrolyzed proteins, and probiotics will be obtained. Finally, in the third stage, the residue from the previous stage can be used to generate biogas. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd

“…For example, partial demineralization (up to ~30%) of sweet whey can be achieved by removal of monovalent ions using an appropriate NF membrane system. Nanofiltration was recently demonstrated in both lab scale (42) and pilot scale (43), for removing lactic acid from acid whey, a low saline waste stream from Greek yogurt and cream cheese manufacturing, to allow for the recovery of whey proteins and lactose in a downstream drying unit. A process called Ultra-Osmosis® (44) was reported to selectively remove the dissolved salts from salty whey, achieving a retentate stream close to that of normal sweet whey.…”
