1. A method for monitoring a manufacturing process of an agricultural product, the method utilizing hyperspectral imaging and comprising: (a) scanning at least one region along a sample of agricultural product using at least one light source of a single or different wavelengths; (b) generating hyperspectral images from the at least one region; (c) determining a spectral fingerprint for the sample of agricultural product from the hyperspectral images; and (d) comparing the spectral fingerprint obtained in step (c) to a spectral fingerprint database containing a plurality of fingerprints obtained at various points of the manufacturing process, using a computer processor, to determine to which point in the manufacturing process the sample has progressed.
