| 摘 要： | 选用4种大孔树脂(LSA-10、AB-8、NKA-Ⅱ和HP-10)对紫小麦麸皮花色苷进行吸附与解吸试验,研究了大孔树脂对紫小麦麸皮花色苷的静态吸附动力学曲线、吸附等温曲线及解吸特性。结果表明:在25℃条件下,HP-10型大孔树脂对紫小麦麸皮花色苷的吸附量、解吸量和吸附平衡常数分别为9.349 mg/g、7.523 mg/g和0.777 7,均高于其他3种树脂。经HP-10型大孔树脂纯化后,紫小麦麸皮色素的色价是纯化前的3.7倍。

| Abstract: | The experiments of adsorption and desorption of bran anthocyanins by four macroporous resins(HP-10,LSA-10,AB-8 and NKA-Ⅱ) were carried out on purple wheat.The static adsorption curve and adsorption isotherm were drawn,and the desorption characteristics were studied.The results revealed that the adsorption,desorption and absorption equilibrium constant of HP-10 on purple wheat bran anthocyanins at 25 ℃ were 9.349 mg/g,7.523 mg/g,and 0.777 7,respectively,which were higher than those of LSA-10,AB-8 and NKA-Ⅱ.The color value of purple wheat bran anthocyanins purified by macroporous resin HP-10 was 3.7 times the value of unpurified. |
