Response surface curves for Chroma: (a) effect of sucrose concentration and temperature at contact time 30 min; (b) effect of sucrose concentration and contact time at temperature 30°C. The dashed square line is for air-dried sample (Chroma = 34.0), and the solid square line is for the freeze-dried sample (Chroma = 29.2).
