Abstract

Rapid and accurate determination of the oil, moisture and protein content in grains and oilseeds on the field and at receiving stations has been dream for many years.The requirements for field analysers are very stringent. Light emitting diodes are promising radiation sources for spectroscopic analysers.Based on LEDs, VTT Electronics has developed a handheld 32 channel SWNIR (830-1050nm) transmittance grain analyser prototype.For whole grain wheat moisture measurement, we received an SEP of 0.14 and for protein the values SEC 0.23 and SEP 0.32.After the development of the handheld analyser prototype, VTT Electronics has improved the LED spectrometer module, through which the signal-to-noise ratio of the module has been improved by almost an order of magnitude overall, while even more than two orders of magnitude at the long wavelength end.This is likely to bring about a remarkable improvement in the accuracy of protein measurement.
