Internationally, the types of pesticide residue tests on apples are increasing and the test limits are becoming stricter, which to some extent restricts China's apple exports. To ensure the quality and safety of apple production, it is particularly important to strengthen the research on the detection and analysis of pesticide residues in apples, as well as the standards and control technologies for pesticide residues. comen 
Now there is a safe and effective technical method for removing organochlorine pesticide residues from fresh apples by ultrasonic waves. Experimental verification has shown that under certain power, temperature and time conditions, the removal rate of organochlorine pesticide residues in apples by ultrasonic treatment has reached 59.24%, effectively eliminating the organochlorine pesticide residues in apples and enhancing their safety. During the process of treating apples with excessive pesticide residues using ultrasonic technology, researchers also conducted relevant evaluation studies on the impact of ultrasonic technology on the main qualities of apples. The results show that although ultrasonic treatment has a certain impact on the total sugar and total acid content of apples, it does not exceed the requirements of national standards and the standards of apples in major exporting countries.
Experts say that because ultrasonic processing technology is simple and fast, it can be easily coupled and linked with existing fresh fruit cleaning, grading and waxing production lines. Therefore, the industrial application prospects of this technology are extremely broad.
