Turbidimetric determination of the total glucozinolate content of rape
The objective of the investigation was to develop a procedure for the determination of the total GZ (glucozinolate--non-nurishing substances found in rapeseed) content from the content of sulfate ion SO/sup 2 -4/which is formed in the fermentative hydrolysis of GZ, based on the degree of turbidity formed by the addition of a barium chloride solution in the presence of the surfactant Tween-80 (poly(20)ethoxysorbitan monooleate.). The supernatant liquid is used to determine the SO/sup 2 -4 -/ion before and after fermentative hydrolysis. The GZ content of the analyzed sample of rapeseed raw material was calculated from an equation. Data show that the precision, reliability, and reproducibility of the results obtained by the proposed method are satisfactory. The procedure can be sued for serial analysis in selection establishments as well as feed production plants.
