“…their ability to promote the water structure. These theories are known under the label of hydration theories [17][18][19][20]. Based on these theories, the competition between the interactions of PPG with surrounding water molecules and the water-structuring forces originate from the presence of the kosmotropic electrolyte is often a determinant for the formation of an ABS in the ternary PPG + kosmotropic (i.e.…”

“…15, 308.15, and 318.15) K. The obtained results are necessary for the design and optimization of extraction processes and can also be used to develop the thermodynamic models for ABS. In the studied system, the effects of temperature and pH on the phase separation were analyzed using the corresponding composition phase diagrams and the hydration theories [17][18][19][20]. Under the label of the hydration theories the phase separation in the investigated system may be interpreted based on the water-structure-promoting capability of the used inorganic salt in company with the complex and competing nature of the interactions between the solutes (i.e., polymer and ions from the inorganic salt) and water which in turn may be affected with the working temperature or the aqueous medium pH.…”

“…The majority of hydrophobic moieties are buried inside the quaternary or tertiary structure due to a hydrophobic effect, and the majority of hydrophilic moieties are on the surface, free to participate in protein-water interactions. 'Salting-in' of proteins typically occurs at low salt levels, where the ions act to increase order of the protein's hydration layers and promote protein-water interactions [78][79][80][81][82][83]. However, at high levels of salt, hydration layers can be disrupted as ion-water interactions become favored over protein-water interactions in a 'salting-out' process [78][79][80][81][82][83].…”
Interest in alternative protein sources to those derived from animal, soy and wheat is on the rise, as consumers are searching for lower cost, healthier alternatives without compromising product quality and safety. Pulses are rich in protein, carbohydrates, vitamins and minerals and are low in fat. Although pea proteins experience greater integration into the plant protein ingredient market than others, lentil, chickpea, bean and faba beans are not far behind. This review discusses approaches used for extracting pulse proteins used to produce protein products (concentrates/isolates), mechanism driving structure-function relationships as well as potential applications.
“…These theories, which constitute the oldest and simplest explanation of salting-out, postulate that ions in solution attract and are consequently surrounded by a layer of solvent moleculesa process commonly referred to as ionic hydration. This effectively immobilizes solvent molecules and quenches their role as solvents. − When an electrolyte is added to a solution of a nonelectrolyte, they compete with each other for solvent molecules. As expected, the competition is won by the electrolyte ions (or ions with a relatively strong affinity for the solvent), and those of the nonelectrolyte (or ions with a relatively less affinity for the solvent) lose.…”

“…As a consequence, the nonelectrolyte precipitates from the solution. Thus, according to the hydration theories, salting-out is attributable to the preferential movement of solvent molecules from their role as the solvent for ions of the nonelectrolyte. − These theories are depicted in Figure . 1 Diagrammatic representation of the hydration theories.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
