2.5. Colour measurement
Juice colour was measured using a CR-200 Minolta
Chroma meter (Minolta, Chuo-Ku, Osaka, Japan) with
an 8 mm measuring area. A Minolta standard-white reflector
plate was used to standardise the instrument under CIE
(Commission International de L’Eclairage) illuminating C
conditions. Samples of orange juice were filled into
60 mL glass assay tubes and CIELab values were determined.
All samples were analysed in triplicate
