Non-destructive testing of new technology cracked eggs successfully "first knocked after" took out "bad guys"

According to Xinhua News Agency, Beijing, December 28th (Reporter Yu Xiaojie and Wu Jingjing) used a camera to take pictures of light transmitted through the eggs, and then used a microphone-like instrument to obtain the sound after the eggs were struck, and 98% of cracked eggs could be detected. This new non-destructive testing technology can effectively guarantee the quality of eggs in the industrial production of eggs.

The reporter learned from the meeting of the China Association of Science and Technology journals and news media held on the 28th that the results of the work completed by the academic team led by Dr. Pan Leiqing of the Food Science and Technology College of Nanjing Agricultural University were published in the Journal of Agricultural Engineering, 2010. In the period. Egg shells are thin and easily broken, bacteria will quickly invade and reproduce, causing corruption, deterioration, affecting people's health. Therefore, removing "bad guys" is an important part of egg production, management and processing. “We simulated human eyes, ears, and both methods to detect cracked eggs. The results show that the new method using two technology information fusion models can detect cracked eggs with a detection rate of 98%, and can fully avoid cracks. The hidden dangers caused by egg safety ensure product quality." Pan Leiqing said.
