The scientists studied the dissociation of sodium caseinate at pH 12 and its re-association after neutralization occurred, using dynamic light scattering and analytical ultracentrifugation. At pH 12, sodium caseinate particles dissociated into smaller particles with loose structures that enabled them to interact with the deprotonated curcumin.
These methods include site exclusion chromatography (SEC), which complements other techniques such as analytical ultracentrifugation (AUC), a very powerful but complex and slow technique.
