Impact of Power Ultrasound on Antihypertensive Activity, Functional Properties, and Thermal Stability of Rapeseed Protein Hydrolysates

Figure 4

Effect of enzymolysis with and without sonication on protein solubility of rapeseed protein. Pretreatment conditions were ultrasound power 600 W and pretreatment time 12 min. Hydrolysis time 120 min. RPH (protein hydrolysate without pretreatment) and US-RPH (protein hydrolysate with pretreatment). Different lowercase letters denote statistically different values ().
