Phycocyanin is a protein-chromophore structure present in Arthrospira platensis commonly used as a blue-colorant in food. Color losses of phycocyanin can be reduced by electrostatic complexation with λ-carrageenan. The aim of this study was to inves

The protein-chromophore interactions of phycocyanin are prone to changes in environmental conditions. Loss of these interactions leads to disappearance of the color. After stabilization with λ-carrageenan, phycocyanin can be stabilized over 28 days.

The pH and temperature sensitivity of the natural blue pigment phycocyanin from Arthrospira platensis limits its application as food colorant. This study examines the effect of protein stabilization by the anionic polysaccharide λ-carrageenan on phy

New insights in the aggregation mechanisms of the whey protein β-lactoglobulin were gained by detailed investigation of the denaturation behavior (80–120 °C) at variable pH values (5.1, 6.8, 8.0). Denaturation followed a 1.5 order kinetic and rea

Since there has been a lack of knowledge concerning the molecular understanding of the specific fouling mechanism during deposit layer structure formation, in this study membrane fouling during the filtration of single whey protein fractions was inve

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

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
