摘要 为了从枇杷皮中提取色素并研究其稳定性,以枇杷皮为原料,以乙醇为浸提剂,用微波法提取色素,研究在不同金属离子、pH值、光照时间、温度、食品添加剂和氧化剂、还原剂等条件下的稳定性。结果表明,光照时间和pH值对色素稳定性的影响较大,而金属离子、温度、食品添加剂、氧化剂、还原剂等对色素的影响相对较小。枇杷皮色素在不同金属离子、食品添加剂、氧化剂和还原剂中有较好的稳定性。 With loquat peels as raw material and alcohol as the extracting, pigments can be extracted from the loquat peel through microwave extraction. Under different circumstances, including different metal ions, pH degree, illumination time, food additives,antioxidants, and reducing agents, the research about its stability were carried out. The final result indicates that illumination time and pH degree have greater influences on the stability of pigments ,whereas met- al ions, temperature, food additives, antioxidants, and reducing agents has fewer effects on its stability. Loquat peel pigment has quite a good stability under the conditions of different metal ions, food additives, oxidants and reducing agent.
