Abstract
"Natural food colorant is going to be the only edible colorant in the future while people are starting to turn their back on artificial food colorants. This study is to observe one of the potential alternative source, which is polyacylated anthocyanin from Butterfly pea flower. The stability of polyacylated anthocyanin still needs improvement by the addition of DMSO at the optimal concentration. There were three factors in this research, which were concentration of DMSO (0%, 10%, 20%, 30%, 40% and 50%), common food pH conditions (6, 7 and 8), and temperature conditions (30C, 45C and 60C). Color intensity, total anthocyanins content, hypsochromic shift and browning index were used as the stability parameter. Based on this study, DMSO was able to elevate the stability of polyacylated anthocyanin from Butterfly pea flower. The optimal concentration of DMSO was found slightly different in each pH conditions. The maximum temperature that DMSO still able to retain the color was at 45C.
