Fat droplet size distribution in emulsions and rehydrated powders with (A) EDTA and (C) EDTA and SDS. The symbol equivalence is: emulsion after homogenization (◆), emulsion after spraying with spray nozzle at a feeding rate of 1.8 kg·h⁻¹ (△) and 3.0 kg·h⁻¹ (▲), rehydrated powders dried at inlet air temperature of 180 °C (×) and 255 °C (*). (B) Phase-contrast light micrographs in the initial emulsion (left) and in a rehydrated powder (right). Scale bar = 10 μm. (D) Volume-weighted diameters d ₄₃ (□) and d(0.9) (■) in emulsions and rehydrated powders with EDTA and SDS, as a function of processing step and feeding rate to the spray-drying chamber: 1.8 kg·h⁻¹ (small symbols) and 3.0 kg·h⁻¹ (large symbols). n = 6.
