磁性纳米粒子辅助加热技术在鱼类解冻中的应用

Application of Magnetic Nanoparticles Assisted Heating Technology in Fish Defrosting

摘要:

随着食品工业的快速发展和消费者安全意识的提高，人们越来越注重食品质量与安全。冻藏是食品长期贮藏的最常用方法，但食品品质在冷冻解冻后还存在一些劣变，如由解冻汁液流失造成的营养损失，脂质和蛋白质氧化严重，肌肉纤维组织受到破坏等，因而寻求一种安全高效的新型解冻技术尤为重要。磁性纳米粒子辅助加热是一种新型食品解冻方法，它大大改善了传统解冻和新型解冻方法出现的氧化严重、感官不佳等问题。作者综述了食品解冻中存在的品质劣变问题和磁性纳米粒子辅助加热在鱼类解冻中的应用，以期为该技术在食品解冻中的应用提供参考。

Abstract:

With the rapid development of food industry and the increase in consumer safety awareness, consumers are also paying more and more attention to food quality and safety. Frozen storage is the most common method for long-term storage of food, but there are still some deteriorations in food quality after freezing and thawing, such as the nutrient loss caused by the loss of thawed juice, the serious oxidation of lipids and proteins, and the damage to muscle fiber tissue. Therefore, it is particularly important to seek a new safe and efficient thawing technology. Magnetic nanoparticles assisted heating is a new type of food thawing method, which greatly avoids the conventional problems of traditional thawing and new thawing methods. Magnetic nanoparticle assisted heating is a new thawing method of food, which greatly improved the comment problems in the traditional and new thawing methods, such as serious oxidation and poor sensory performance. The present article reviews the quality deterioration issues in the thawing of food and the application of magnetic nanoparticle-assisted heating in the thawing of fish, in order to provide reference for the application of this technology in food defrosting.
