Beschreibung
Zusammenfassung:	•The casein was treated by multi-frequency power ultrasound (MFPU).•The hydrolysis degree was significantly improved under tri-frequency MFPU treatment.•Surface topography and nanostructures of caseins were damaged after MFPU treatment.•MFPU can be used as an efficient method to promote casein enzymolysis. Effect of multi-frequency power ultrasound (MFPU) pretreatments on the degree of hydrolysis (DH) and mechanism of casein during alcalase enzymolysis was investigated. Results showed that MFPU pretreatment in tri-frequency 20/40/60 kHz mode significantly (p
