Chroma ( fig. 2b) showed a similar trend to that of lightness for the internal side of the slices, with reduced values at the higher pressures (>500 MPa). However, the back of the tissue slice ( dark green tissue) showed an increase in chroma only at pressures of 200 MPa at 3 min, no significant difference at pressures of 300-500 MPa, and adecrease at 600 MPa for 3 and 6 min
