采用正交试验对甜樱桃果实红色素的最佳提取条件进行研究,并探讨该色素的稳定性.结果表明,以周液比1:8(m/V)加入体积分数90%乙醇溶液,超声处理5min,在50℃水浴中提墩效果最好:该色素属水溶性色素,耐室内自然光、耐热性强,耐氧化性较差,除Al~(3+)、Fe~(3+)外,其余金属离子对色素均无影响,在酸性介质、还原剂以及常用的食品添加剂等条件下有较好的稳定性,可作为食品饮料、医药等行业的天然植物色素.

Ethanol was used to extract natural red pigment from sweet cherry fruits under the assistance of ultrasonic.The optimal extraction process was investigated using orthogonal army design.Along with this,the stability of pigment product obtained was dealt with.Results showed that using 90% ethanol to extract raw material in 50 "C water bath under the assistance of ultrasonic treatment for 5 rain gave an optimal red pigment extraction.The pigment was easy to dissolve in water,and had poor resistance to indoor natural fight,heat and oxidation.Except Al3+ and Fe~(3+),other metal ions including Mg~(2+),Ca~(2+),Cu~(2+),Zn~(2+),Na~+,and K~+ had no obvious effects on the pigment.In acidic medium or in the presence of reductants or common food additives,the pigment exhibited good stability.Therefore,the pigment as a natural plant-derived pigment can be extensively used in food,medicine industries,and so on.
