Rehydration in an alkaline solution has been shown to improve the rehydration behaviour of milk protein isolate (MPI). In this study, the focus is on citric acid neutralization of MPI powder dissolved in alkaline solution. The results showed that alkalization induced more negative zeta-potential compared to MPI control, reducing it from -22.4 mV to -32.6 mV. Neutralization had a relatively similar zeta-potential value as alkalized sample. Sodium carbonate addition increased pH and caused a…

Influence of calcium on the properties of micellar casein in goat milk
Abstract This study aims to investigate changes in the properties of micellar casein of goat milk caused by the addition of two types of calcium, natural milk calcium and calcium chloride, and
Influence of acidification or alkalization followed by neutralization on dissolution and acid gelation ability of MPI
Abstract Rehydration of milk protein isolate (MPI) powder in water is poor which requires more than 24 h, however it is greatly influenced by solution pH. This study analysed the rehydration of MPI

Effect of calcium chelators on physical changes in casein micelles in concentrated micellar casein solutions
Abstract The effect of calcium chelators on physical changes of casein micelles in concentrated micellar casein solutions was investigated by measuring calcium-ion activity, viscosity and turbidity,
Effect of sodium carbonate on the rehydration of milk protein isolate powder
Abstract Milk protein isolate (MPI) powder has poor rehydration ability. An alkaline pH environment has the potential to alter and improve its rehydration behaviour. Sodium carbonate, an approved
Reassembling of Alkali-Treated Casein Micelles by Microbial Transglutaminase.
The results showed that the extent of cross-linking is mainly influenced by protein conformation and not by pH value, which leads to the conclusion that αs2-casein is mainly located in the inner center of casein micelles and is only accessible for enzymatic cross- linking after alkaline swelling of the micelle.
Effect of calcium sequestration by ion-exchange treatment on the dissociation of casein micelles in model milk protein concentrates
Abstract This study investigates the effect of partial depletion of Ca from milk protein concentrates (MPCs) on the dissociation of the casein micelles. Series of MPCs with 0, 10.5, 19.6, 29.6, 38.7
Physico-chemical changes in casein micelles of buffalo and cow milks as a function of alkalinisation
By modifying the forces (hydrophobic and electrostatic interactions, hydrogen bonding and presence of micellar calcium phosphate) responsible for the structure and the stability of casein micelles,
The effect of transglutaminase on reconstituted skim milks at alkaline pH
Abstract The effect of transglutaminase (TG) treatment on the changes in the physico-chemical properties of reconstituted skim milk (10% w/w) under alkaline conditions (pH ∼6.7 to ∼10) was
Reformation of casein particles from alkaline-disrupted casein micelles
Differences in heat stability, ethanol stability and zeta-potential can be explained in terms of the influence of increased concentrations of sodium and chloride ions in milk containing reformed casein particles.
Effects of calcium chelating agents on the solubility of milk protein concentrate
The aim of this study was to determine the effects of calcium chelating agents on the dissolution and functionality of 10% (w/w) milk protein concentrate (MPC) powder. MPC powder dissolution rate and
Effects of milk pH alteration on casein micelle size and gelation properties of milk
ABSTRACT The effects of changes in pH above and below the natural pH of milk (ca 6.6) on the casein micelle size and the gelation properties of the pH adjusted and restored samples were investigated.
The effect of pH on the wetting and dissolution of milk protein isolate powder
Abstract Milk protein isolate (MPI) powder is an important food ingredient powder but it has poor wettability and dissolution ability which limit its functional usage. The effect of pH (5.4–8.4) on
