摘要:

为提高樟树果实红色素RPCF(red pigment from camphor tree fruit)的色价,采用静态吸附和动态解吸附的方法,以吸附率和解吸率为评价指标,研究了大孔树脂吸附与解吸附RPCF性能。结果表明:D406树脂对RPCF的吸附效果较好,在吸附液pH3时吸附能力较强;以pH6、流速为1BV/h的50%乙醇为洗脱液的洗脱效果较好。经D406大孔树脂吸附与解吸附后的色素色价提高了4.8倍。

Abstract:

Red pigment from camphor tree fruits (RPCF) was purified by macroporous resin adsorption to elevate its color value. D-406 resin was chosen from 7 types of macroporous resins for the purification due to excellent adsorption capability. Subsequently, the optimal adsorption and desorption conditions of RPCF were investigated by single factor test and an enlarged test was carried out to verify them. Results indicated that an optimal purification of RPCF could be achieved through a procedure based on adsorption of sample solution at pH 3, followed by desorption using 50% ethanol solution at pH 6 with a flow rate of 1 BV/h, which resulted in a 4.8-fold increase of color value.

Key words: macroporous resin, camphor tree fruit, natural pigment, purification
