Fig. 3 - Effect of ultrasound application onset temperature for 7 s at 0.26 W cm-2 on the nucleation temperature (a), nucleation temperature versus ultrasound application onset temperature (b) and delay from application to nucleation (c) of radish cylinders. Arrows and boxes indicate the ultrasound application trigger points and nucleation temperature, respectively. Different lowercase superscript letters (a-c) represent significant differences of delays under different ultrasound application onset temperatures (p < 0.05).
