Screening for erucic acid and glucosinolate content in rapeseed-mustard seeds using near infrared reflectance spectroscopy

Abstract

Using partial least square regression, calibration for non-destructive estimation of erucic acid and glucosinolate contents in seeds of rapeseed-mustard by Fourier transform near infrared reflectance spectroscopy (FT-NIRS) was developed. The calibration developed showed a very close relationship between the reference method for erucic acid (gas chromatography) and glucosinolate content (palladium complex formation) and NIR spectral data from 7502.1 to 5444.6cm. (-1) The coefficients of determinations were 97.16% and 98.34% for erucic acid and glucosinolate contents, respectively.
