摘要
超声波解冻通过空化效应、机械效应和热效应对冷冻食品进行解冻,解冻效率高、对冷冻食品的损伤较小。该文简要介绍了空气解冻、水解冻和电解冻的解冻机制及研究进展,详细阐述了超声波解冻的机制及研究进展。将超声波解冻与空气解冻、水解冻和电解冻进行对比,发现超声波解冻的解冻效率最优,且将超声波与这3种传统解冻方式结合可以提高解冻效率,并且获得更好的解冻效果。超声波频率和强度以及冻结食品的解冻温度是影响解冻效果的主要参数。超声波在食品中的衰减程度受到解冻温度的影响极大,因此在调节超声波频率和强度同时调控解冻温度对解冻效果至关重要。
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.
