摘要
以苹果皮为原料,用70%vol的乙醇(pH3)超声波辅助提取苹果皮红色素,研究了色素的稳定性。结果表明,苹果皮红色素在酸性条件下对高温、自然光、常见金属离子、碳水化合物和还原剂具有良好的稳定性。
Red pigment was extracted from apple peel by 70 % ethanol （pH=3） supplemented with ultrasound. The stability of red pigment was subsequently studied. The results indicated that such red pigment had favorable stability for high temperature, natural light, common metal ions, carbohydrates, and reducing agents in acidic conditions
