Surface color was measured using a digital color imaging system (DigiEye, VeriVide., Leicester, UK) equipped with a digital camera (Nikon D7000, 35 mm lens, Nikon, Japan) and a light-box illuminated by standardized daylight (CIE D65) as described by Aaby et al. . For each recipe slices from 6 individual samples were recorded. Color measurements of the pictures were made in the CIE color (L*a*b*). Color (Table ) are given as the average of six replicated measurements pr formulation (tubes 1-6).
