摘要:

通过对树脂种类、吸附时间、洗脱液浓度及干燥方法的研究,确定黑莓色素纯化的条件为LS-300B 型大孔树脂,上样液pH3.00,吸附平衡时间5h,解吸附乙醇浓度70%,冷冻干燥。在此条件下,黑莓色素的得率为0.58%,花色苷回收率为79.47%,色价为45.21,总花色苷含量为12954.987mg/100g。

Abstract:

After being extracted from blackberry fruits with the mixture of 1% HCl and 80% ethanol (1:99, V/V), the crude pigment was purified with macroporous adsorption resin, and then dried to powder by different processes. Moreover, we conducted the scale-up production experiment of blackberry pigment under optimized conditions. When blackberry pigment in citric acid- Na2HPO3 system at pH 3.00 was adsorbed by resin LS-300B for 5 h, and then desorbed by 70% ethanol, the best purification was achieved. Compared to vacuum and spray drying processes, freeze drying exhibited the best effect. Results of the scale-up production experiment showed that yield and color value of the blackberry pigment were 0.58% and 45.21, respectively; total anthocyanin content in the blackberry pigment was 12954.987 mg/100 g, and recovery of anthocyanin was 79.47%.
