Effects of water content in DES solution (A), ultrasonic power (B), ultrasonic time (C), and liquid–solid ratio (D) on the yield of total phenolics extracted from of thinned young kiwifruits by ultrasound-assisted deep eutectic solvent extraction. TPC indicates total phenolic content; different letters (a–e) indicate significant differences at p < 0.05 determined by ANOVA.
