苹果汁中重金属检测方法研究进展

Research progress of detection methods of heavy metals in apple juice

我国是苹果生产大国,其生产和消费规模均占全球50%以上。苹果汁作为苹果加工的主要形式,其营养丰富,味道鲜美。然而由于原料、技术与管理等问题,致使苹果汁经常出现褐变、农药残留、棒曲霉素、耐热菌超标、重金属污染等问题。随着人们对果汁安全性要求的不断提高,重金属超标问题越来越引起人们重视,故对重金属检测技术的开发成为重要的研究方向。针对苹果汁中重金属污染问题,本文综述了近年来重金属离子的检测方法,并对重金属检测技术的发展趋势进行了展望。

China is a big producer of apples, and its production and consumption accounts for more than 50% of the world. As the main form of apple processing, apple juice is rich in nutrition and delicious. However, due to the problems of raw materials, technology and management, apple juice often suffers from browning, pesticide residues, patulin, excessive heat-resistant bacteria, and heavy metal pollution. With the continuous improvement of safety requirements for fruit juice, people pay more and more attention to the problem of excessive heavy metal. Therefore, the development of heavy metal detection technology has become an important research direction. In view of the problem of heavy metal pollution in apple juice, this paper summarized the detection methods of heavy metal ions in recent years, and forecasted the development trend of heavy metal detection technology.
