Research progress of near infrared spectroscopy and hyperspectral imaging in determination on quality of oilseed and its products

Oilseed and its products play a vital role in our life, which provide human beings with energy, essential fatty acids and nutrients. The quality of oilseed and its products can affect the economic benefit of enterprise and physical health of people directly. In recent years, near-infrared spectroscopy and hyperspectral imaging technology were widely used in the rapid assessment of quality of oilseed and its products. In this review, the principle and operation process of near-infrared spectroscopy and hyperspectral imaging technology were briefly introduced, and then the applications of this technique in rapid determination on quality of oilseed products were reviewed, including the detection of physicochemical properties, identification and geographical origin traceability of oilseeds, and authentication of edible oils. Moreover, the development prospects of near-infrared spectroscopy and hyperspectral imaging technology in determination of oilseed and its products quality were also anticipated.
