China Agricultural University successfully developed a non-destructive fruit detector

March 27, 2019

Recently, Han Donghai, an associate professor of the College of Food Science and Nutritional Engineering at China Agricultural University, and his research team have successfully developed a new non-destructive fruit testing instrument that can be used to detect internal quality without damaging the fruit. This achievement fills the gap in domestic non-destructive testing methods for Yam's black heart disease. It has significantly improved the detection accuracy of apple water heart disease and the correct discrimination rate of browning apple, and it has reached the advanced level of international similar research. I believe many consumers have had this experience: In the fruit market, some fruits look very bright, but in fact they have already rotted. Nowadays, China National Agriculture University has successfully developed a new non-destructive fruit detection instrument. Using this instrument, it can test its internal quality without damaging the fruit, so as to provide fruit cultivation management, quality control, sorting, and classification. Reliable internal quality basis. The results of this "rapid internal non-destructive testing method for fruit quality" have successfully passed the results appraisal organized by the Ministry of Education.

It is reported that this research was completed by Han Donghai, associate professor of the College of Food Science and Nutritional Engineering, China Agricultural University and his research team. They adopted the method of fast non-destructive testing using short-wave near-infrared transmission spectroscopy and independently developed detection equipment for apple waterborne disease and Yam pear black heart disease. This new technology uses the principle of optical transmission to quickly determine the quality of its internal quality, such as water heart disease apples, internal browning apples, black-hearted pears and other fruits, without damaging or damaging them.

Experts indicated that this achievement has filled the gap in domestic non-destructive testing methods for Yam's black heart disease, and has significantly improved the detection accuracy of apple water heart disease and the correct discrimination rate of browning apples, which has reached the advanced level of international similar research in general. . This method has the characteristics of high accuracy, simple equipment, and easy operation compared with similar international detection methods. It has been proved by trials in orchards in Beijing and Shanxi. This technology provides advanced non-destructive testing methods for improving the quality control of China's fruit products and has a very broad market prospect.
