Effects of HPP on casein micelle size.

Sample	Treatment	Observation	Reference
Raw skimmed milk	100–200 MPa	No observable changes in casein micelle size.	[10,39,50]
	250 MPa, 15 min, 40 °C	Approximately 25–30% increase in micelle size; reversible during storage.
	200 MPa, 60 min, 30–40 °C
	300 MPa, 5 min, 40 °C
	>300 MPa, 40 °C	Approximately 50% decrease in micelle size; irreversible.
	300–800 MPa
