Interpretive Summary: Utilizing optical technology in non-destructive diagnosis and quality control of agricultural and food and feed products is expanding in a fast pace in recent years. This article reviewed recent contributions to this area of research from the Non-Destructive Detecting Laboratory at the China Agricultural University, Beijing, China. The review highlights three timely and sensitive research areas they have made significant progresses. The areas are: 1) using hyperspectral imaging technology to detect aflatoxin on maize kernels; 2) Using Near-infrared spectral imaging and hyperspectral imaging in poultry meat quality control; and 3) Using these optical imaging technologies to detect food adulteration. Their multiple disciplinary collaborative team includes two USDA-ARS Research Units. Aflatoxin detection in maize kernels at pre-harvest was performed by a joint effort with Crop Genetics and Breeding Research Unit, USDA-ARS at Tifton, GA, whereas the work on poultry meat quality control was the result of collaborative research with Quality and Safety Assessment Research Unit, USDA-ARS at Athens, GA. The review also provides future research directions in this fast-expanding research area.

Technical Abstract: Near infrared spectroscopy and hyperspectral imaging are fast-growing, rapid, powerful, and non-destructive optical technologies that can be used especially in quality and safety control of agro-food products. The Non-Destructive Detecting Laboratory for Agricultural and Food Products in the College of Engineering at the China Agricultural University located in Beijing, China, has engaged in research on sensing and characterizing agro-food quality and safety attributes with the latest optical methods including near infrared spectroscopy and hyperspectral imaging for over five years. In this report, the latest research and developments through multidisciplinary international collaborations was highlighted to demonstrate our contributions to the research area of utilizing near infrared spectroscopy and hyperspectral imaging sensing technology to improve non-destructive diagnosis and quality control of agricultural and food products.
