\u00cen tabelul 1 sunt prezentate rezultatele a cinci m\u0103sur\u0103tori individuale efectuate cu aparatul Agera L2 de la HunterLab<\/strong>. \u00cen acest scop, fulgi de ov\u0103z dintr-un lot au fost introdu\u0219i \u00eentr-o cuv\u0103 de sticl\u0103 cu diametrul de 6 cm, iar culoarea a fost m\u0103surat\u0103 prin fundul cuvei<\/strong>. \u00centre m\u0103sur\u0103tori, cuva a fost golit\u0103 \u0219i umplut\u0103 din nou cu produs din acela\u0219i lot. Din aceste 5 m\u0103sur\u0103tori s-a calculat apoi valoarea medie.
