| Abstract: | Chilled food is thawed by ultrasonic thawing through cavitation effect,mechanical effect and thermal effect.Ultrasonic thawing has high thawing efficiency and can keep good quality to chilled food.The mechanisms and research progress of air thawing,water thawing,electricity thawing and ultrasonic thawing was detailed and evaluated.It was found that combined ultrasonic thawing with traditional thawing methods could effectively improve the thawing effect.The key parameters of ultrasonic thawing were frequency,intensity and thawing temperature.Moreover,the thawing temperature of chilled food had great influences on ultrasonic wave attenuation,not only the frequency and the intensity,but also the thawing temperature of the ultrasonic wave was important to thawing importance. |
