Abstract
Property, quality and safety assessment of agro-products are increasingly gaining attention due to the potential human health concern as well as social sustainable development. Emerging techniques and methods have particular advantages in nondestructive evaluation of agro-products due to their simplicity and faster response time, and reliable results, compared with the conventional visual inspection and destructive methods. This chapter briefly elaborates the principles and system components of some representative techniques, in particular, near infrared spectroscopy, infrared spectroscopy, fluorescence spectroscopy, Raman spectroscopy, laser induced breakdown spectroscopy, traditional machine vision, hyperspectral and multispectral imaging, magnetic resonance imaging, X-ray imaging, thermal imaging, light backscattering imaging, electrical nose and acoustics. The recent applications and technical challenges for these representative techniques are also presented.
