Stability of the color extracted by both solvent and SC-CO2 extraction was depicted by their T1/2 values.
The T1/2 values of different color extracts stored at 4 C have been tabulated in Table 1. At 10 MPa, T1/2 values decreased with extraction temperature (60e 80 C); whereas, at 12e15 MPa, it increased with extraction temperature.
The color extracted at 60 C, 10 MPa has shown maximum stability of 138.63 days when stored at 4 C.
