*2.11. Color Properties*

A digital colorimeter (Minolta, model CR-400, Tokyo, Japan) was used. Fruit peel colour was monitored at two selected and ring-marked positions per fruit. Aril colour was monitored in a Petri dish at two random spots per sample. Values of *L*\*(lightness), *a*\* (redness), *b*\*(yellowness), and *C*\* (chroma) were measured. Where, *a*\* describes surface color in the range from green (−*a*\*) to red (+*a*\*), while *b*\* ranges from yellow (+*b*\*) to blue (−*b*\*). Monochromaticity *L*\* ranges from 0 (black) to 100 (white). *C*\* was calculated by equation 1 [30].Twelve replicates were considered per packaging treatment.

$$\mathbf{C}^\* = \left(a^{\*2} + b^{\*2}\right)^{\frac{1}{2}} \tag{1}$$
