| Abstract: | The extraction conditions are obtained by single factor experiments, including the biggest absorption wavelength, the best extraction solvent, feed ratio, extractive temperature and time. The orthogonal test of the optimum extraction conditions, also the stability of pigment from purple ipomoea batatas are studied, the optimum extraction conditions are as follows, 10% of citric acid, 10% of feed ratio, extracting for 1.5 hours, 40 ℃ of extraction temperature. The result of its stability experiment shows that the pigment from purple ipomoea batatas shows instability to H2O2,Na2SO3, light and part of the metal ions, in neutral and acidic pH conditions shows bright red or bright purple, with good thermal stability. |
