ABSTRACT
The calorimetric parameters such as yellowness index (YI) and the total colour difference (ΔE*) between the standard and the tested sample have been applied for the colour description of semolina obtained from Polish breeding wheat lines (Triticum durum). In order to improve the precision of determination using reflectance spectrophotometer, the samples grinded in disk mill have been pressed (50 MPa) into a cake. High values of YI, reflecting large amount of carotenoids, found for Polish wheat were approximately equal to Yl values of imported grains. Increased color differences (ΔE*) and decreased lightness (L*) have pointed to meal contamination with bran particles.

Parametry kolorymetryczne: indeks zażółcenia YI i odległość barwy ΔE* od wzorca, zastosowano do opisu barwy semoliny uzyskanej z ziarna pszenicy polskich linii hodowlanych. Celem poprawienia precyzji oznaczeń na spektrofotometrze odbiciowym, zmielone na młynku tarczowym próbki ziarna przygotowywano w postaci pastylek, stosując ciśnienie 50 MPa. Otrzymano wysokie wartości indeksu zażółcenia – świadczące o dużej zawartości karotenoidów w ziarnic polskich linii hodowlanych i odpowiadające wartościom zbliżonym do próbek ziarna importowanego. Na zanieczyszczenie mlewa elementami okrywowymi z ziarna wskazywała znaczna odległość barwy (ΔE*) i obniżona jasność barwy (L*).
