Comparision of Physicochemical Parameters of Rape Seeds Applying the Infrared Spectroscopy Method

Abstract

Technical progression in sustainable agriculture requires the need for search more and newer analytical methods in order to reduce time of analysis and to minimize costs routine of tests for the highest accuracy of the result. Infrared (IR) and near infrared (NIR) spectroscopy provides such possibility. The paper presents a method of measuring the basic quality parameters (moisture, content of protein, fat, damage and contamination of raw material) of winter rapeseed for cultivars: Abacus, Bellevue, and Adriana+Catana - concoction. Statistically significant differences resulting from various measurement systems between results obtained by means of sieve methods and infrared (IR), were observed. A three-dimensional way of measuring the seed shape used in three dimensional particle size analyzer (AWK 3D) suggests that it is more accurate than the measurement applying two-dimensional method used in the shaker with a set of sieves.
