Extraction the Pigment of Kang-xian Flower and Its Physical-chemical Properties
摘要
Abstract
The extraction conditions and physical-chemical properties of the pigment from Kang-xian flower were studied.Polar solvent such as ethonal,methonal and water were proved to effectively extract the pigment of Kang-xian flower.The most effective solvent to extract the pigment of Kang-xian flower was ethonal-water (60:40,volume ratio).The absorption peaks of the pigment from Kang-xian flower appeared at 220 nm and 260 nm by UV.The color of the pigment of Kang-xian was red at the pH 1-4,but it was faded as the pH value increased.It turned to yellow-green color when the pH value was over 7.The stability of the pigment of Kang-xian flower was good with the light and hot by pH 1 and the temperature was under 60℃.Cu2+ and Fe3+ had great influences on color and stability of the pigment.The food additive Vc also could decrease the stability of the pigment.Relative to the anti-oxidation,the anti-reduction ability of the pigment of Kang-xian flower was seemed more superior.关键词
