Nosenko, I. Hutsalo, V. Nosenko et al. // Ukrainian journal of food science. — 2013. — vol. 1, issue 1. — P. 94-99.https://dspace.nuft.edu.ua/handle/123456789/8675The objective of this study was to analyze of reflectance spectrum in near-infrared region of rapeseed with different erucic acid content and to choose the most informative wavelength for development of calibration equation. Near–infrared reflectance spectra at 1330-2370 nm were measured for rape seed with high and low erucic acid content. The fatty acid composition of seed oil were determined by gas-liquid chromatography. We have detected difference in absorbance level between low and high erucic acid seed in the range of 1700-1860 and 1930-2370 nm. The first derivative of reflectance spectra were analyzed and wavelength set are proposing for development of calibration equation of erucic acid content in rape seed. Our data could be used for determination of erucic acid content in rape seed by near–infrared reflectance spectroscopy.near–infrared reflectance spectroscopyrape seederucic acidінфрачервона спектроскопіяспектри відбиваннянасіння ріпакуерукова кислотакафедра фізики та професійної безпекикафедра технології жирів, хімічних технологій харчових добавок та косметичних засобівArticle
