Investigation of the rehydration characteristics of dairy and infant formula powders using focused beam reflectance measurement and electrical resistance tomography
The potential of focused beam reflectance measurement (FBRM) and electrical resistance tomography (ERT) was evaluated as on‐line process analytical technologies (PAT) for monitoring powder rehydration. Skim milk powder (SMP) and stage one infant formulas were evaluated. Among all samples, SMP had the greatest conductivity by ERT (P < 0.05), this was confirmed by off‐line methods, that is, SMP had a higher solubility, whereas infant formulas had lower solubility. Particle counts for fines of all samples reached peak values ~450 s. Results demonstrated PAT tools offer capability for rehydration characterisation of dairy and non‐dairy powders.
期刊介绍:
The International Journal of Dairy Technology ranks highly among the leading dairy journals published worldwide, and is the flagship of the Society. As indicated in its title, the journal is international in scope.
Published quarterly, International Journal of Dairy Technology contains original papers and review articles covering topics that are at the interface between fundamental dairy research and the practical technological challenges facing the modern dairy industry worldwide. Topics addressed span the full range of dairy technologies, the production of diverse dairy products across the world and the development of dairy ingredients for food applications.
