The butterfly pea solution stored at 4 C showed higher color stability than the solution stored at 40 C. The effect of
rising temperature on color loss was more predominant on neutral solution (pH 7) than the acidic and alkaline solutions (pH 4 and 10, respectively); color remaining of 90% was observed in 15 days at pH 4 and 10 while it was in 1 day at pH 7.
