中文摘要：
研究了不同原料发酵丁二酸提取液的脱色条件。确定了理想的脱色材料——TX-328P粉末状活性炭，得出单一活性炭脱色的优化条件：操作温度为75℃，pH2～3，脱色时间30min，对玉米糖浆发酵提取液，活性炭用量为0．8％，其脱色率达92％，丁二酸的损失率为3．2％；对甘蔗糖蜜发酵提取液，活性炭用量为2．5％，脱色率达97％，丁二酸的损失率为6．2％。采用AB-8型大孔吸附树脂吸附和TX-328P活性炭相结合的两步脱色方法，对甘蔗糖蜜发酵提取液的脱色率达98．2％，两步脱色总丁二酸损失率为6．0％，活性炭用量减少到0．1％，树脂可反复使用。
英文摘要：
The decoloration condition of succinic acid fermentation from corn syrups and cane molasses were investigated. Results show that TX-328P activated char is a suitable decolored reagent. The optimum conditions of solo active carbon discolor method were：temperature 75℃, pH 2-3, adsorption time 30 rain. With adding 0.8% of TX-328P activated char to the solution from corn syrups fermention, the decolorization rate was 92% and the rate of the loss of succinic acid was 3.2%. While adding 2.5% of TX-328P activated char to the solution form cane molasses fermention, the rates of decolorization and the rate of the loss of succinic acid were 97 % and 6.2 % respectively. When decolouration combining AB-8 macro-resin and TX-328P active carbon char, the decolorization rate of the solution from cane molasses fermention reached 98.2% ,and the rate of the loss of succinic acid was 6.0% ,the dosage of TX-328P active carbon char lowed 0.1%,and the resin could be reused.
