The experiments reported in this research paper examine the potential of digestion using acidic enzymes Protease A and Protease M to selectively hydrolyse α-lactalbumin (α-La) whilst leaving β-lactoglobulin (β-Lg) relatively intact. Both enzymes

Two food grade fractionation processes using ion-exchange membrane adsorption chromatography (IE-MAC) and cross-flow electro membrane filtration (CFEMF) were successfully developed for the fractionation of complex peptide mixtures. Feed solutions for

Maillard reaction is influenced by protein and sugar properties, water activity (aw) as well as the glycosylation time and temperature. The aim of this work was to investigate the influence of environmental parameters on the glycosylation reaction ki

Proteins in solution are subject to myriad forces stemming from interactions with each other as well as with the solvent media. The role of the environmental conditions, namely pH, temperature, ionic strength remains under-estimated yet it impacts pr

Whey protein (WP) purification exploits selective heat and salt stabilities. Proteins are denatured. WP α-lactalbumin (α-La) and β-lactoglobulin (β-Lg) are resistant to trypsin (EC 3.4.21.4) and pepsin (EC 3.4.23.1), respectively. This work was t

Trypsin (EC 3.4.21.4) hydrolysis of food proteins are done at the optimum pH (7.8) and temperature (37 °C). Little information is available on the effect of sub-optimal conditions on hydrolysis. Bovine β-lactoglobulin (β-Lg) was hydrolysed by tryp

Whey protein isolate (93.84% protein) was hydrolysed using bovine trypsin (EC 3.4.21.4) at an enzyme-to-substrate ratio of 1.0% (w w −1 ) over a range of temperatures and pH. Residual protein was quantified using reversed-phase high performance liq

Proteins acquire conformation in aqueous media due to the influence of the buffer salt composition and concentration. Such influence may have impact on the enzyme–substrate interaction and somehow steer the enzyme attack properties, leading to rele

Temperature and pH influence the conformation of the whey protein β-lactoglobulin (β-Lg) monomer, dimer, and octamer formation, its denaturation, and solubility. Most hydrolyses have been reported at trypsin (EC 3.4.21.4) optimum conditions (pH 7.8

Tryptic hydrolysis of β-Lactoglobulin (β-Lg) has been shown as an excellent way to produce several functional peptides. However enzymatic hydrolysis results in a mixture of numerous different peptides, which is problematic regarding the enrichment
