Effect of solvent and temperature on the size distribution of casein micelles measured by dynamic light scattering

Different representations of particle size distributions: a) multimodal size distribution; b) lognormal distribution. Sample: raw skim milk in UF permeate at 50°C.

Dynamics of signal intensity (count rate) and effective diameter of unfiltered simulated milk ultrafiltrate at 50°C. kcps=kilocounts per second.

Multimodal size distributions: a) UF permeate, and b) serum protein solution at 20°C.

Comparative particle size distributions: a) skim milk in UF permeate, and b) skim milk after dissociation of CN micelles in EDTA:SDS. Measurements were performed at 20°C.

Dynamics of the effective diameter of CN micelles in raw skim milk diluted with a) UF permeate, b) simulated milk ultrafiltrate, or c) water measured at 6, 20, and 50°C.

Changes in signal intensity (particle counts) during the dynamic light scattering analyses of raw skim milk diluted with a) UF permeate, b) simulated milk ultrafiltrate, or c) water measured at 6, 20, and 50°C.
