Low ph protein aggregation
WebAggregates are formed by association of multiple protein molecules (multimers) held together permanently or reversibly. They range from as few as two to many associated … WebThis study demonstrated that both κ-casein and CMP have the ability to improve the heat stability of whey proteins. The inclusion of κ-casein reduced the size of the aggregates of whey protein after a first heat treatment (90°C for 25 min at pH 7.2) and enhanced their solubility during subsequent heating (90°C for 1 h at pH 7.2).
