摘要: 本论文研究了以桑椹原汁为原料,用大孔吸附树脂制备桑椹红色素的工艺。实验结果表明:AB-8树脂吸附和分离桑椹红色素的交换容量为66.15mg/ml湿树脂。在50℃,pH=2时,吸附能力较强。被吸附的桑椹红色素用pH=1.50,50%乙醇洗脱,洗脱液湿度为室温,洗脱流速为0.5BV/h。AB-8树脂非常稳定,重复使用10次后,交换容量仅降低2.6%。用该工艺生产的色素产品为紫黑色粉末,色价比国家标准提高了近10倍。得率为0.88%。

Abstract: The method for extracting mulberry red pigment from mulberry juice by resin was studied in this paper. The resultsshowed: adsorption capacity of AB-8 resin for mulberry red pigment was 66.15mg/ml wet resin. The optimum conditions of adsorptionwere: temperature 50℃ and pH2.00. All mulberry red pigment that had been adsorbed by AB-8 resin was eluted at room tempera-ture with pH1.5 and 50% alcohol at the flow rate of 0.5BV/h. After ten times of elution, the exchange capacity was only decreasedby 2.6%. The pigment produced by this technological process was purplish dark powder, and the chromosphere was nearly tentimes stronges than that of National Criteria. The yield was 0.88%.
Key words: resin, extraction, mulberry red pigment
