摘要
以山桃稠李果实为试材,通过扫描确定其最大波长为532nm,并用四因素三水平正交实验确定提取山桃稠李色素的最佳条件。结果表明:最佳色素提取条件为30%的乙醇,提取时间90min,提取温度75℃,固液比为1:10。并研究了光、过氧化氢、亚硫酸钠、蔗糖、食盐、金属离子对山桃稠李色素性质的影响。
Took the fruits of Prunus maackii as test materials and though scanning determined that 532 nm had the biggest absorbing wave,by orthogonal test,got the pigment extraction conditions of extraction of pigment from Prunus maackii.The results showed that the best extraton condition were 30%ethanol,extraction time 90 min,extraction temperature 75℃,the liquid-solid ratio 1：10.And the effects of light,hydrogen peroxide,sodium sulfite deoxidization, sugar,salt,metal ions on pigment from Prunus maackii were also studied.
