Extraction kinetics of pumpkin leaf proteins under the various ultrasound duration times and amplitudes (A). The impact of ultrasound amplitudes on the content of white proteins and polyphenols, extracted after 10 min of ultrasound-assisted processing (B). Means with different letters for the same bar groups are significantly different (p < 0.05). Legend: UAE-20%, UAE-30%, UAE-40%, UAE-50%, UAE-60%, and UAE-70% mean an ultrasound-assisted extraction process at 20, 30, 40, 50, 60, and 70% amplitudes, respectively.
