Compared to the blank sample, the custard with solventextracted color (R/Y = 1.33 and B/Y = 0.33) has significant red shade (p = 0.0000).
The sample with the SC-CO2 extracted color (R/Y = 0.2 and B/Y = 0.12) resembled the color of golden yellow custard powder, but was darker.
The resemblance of the latter to the natural eggplant peel color was poor owing to presence of thermosensitive delphinidin-3-rutinoside in higher amount. However, the color was safer owing to low trace metal content.
Both samples of jelly crystal and custard had characteristic odor and taste, with no off-odor or unpleasant aftertaste.
