摘　　要：分别用盐酸和乙酸作为制备海燕Asterina pectinifera体壁胶原蛋白前处理的灰质脱除液,研究了其灰质脱除效果及两种脱除液中各元素的含量。结果表明:乙酸灰质脱除液中有益元素含量钙、镁分别为10.53、0.44 mg/mL,锰、锌、铁、硒分别为4.37、2.98、7.50、0.033μg/mL,除锌、硒含量外,其余有益元素的含量均高于0.4 mol/L盐酸灰质脱除液中的含量,且乙酸对重金属砷的脱除效果也优于盐酸的脱除效果。极差分析结果表明:当乙酸浓度为0.6 mol/L、浸泡时间为3 d、乙酸的添加量为海燕体壁粉的15倍时,乙酸对海燕体壁灰质的脱除效果最好。这说明可以用乙酸来替代盐酸脱除海燕体壁的灰质,既有利于海燕胶原蛋白的制备,又有利于脱除海燕灰质液的综合利用。Hydrochloric acid and acetic acid are used as an ash removal solution respectively in pretreament of collagen extraction from body wall of Asterina pectinifera to evaluate effect of ash removal and elements＇ content in acid solution.The result shows that the beneficial elements＇ contents are 10.53 mg/mL of Ca,0.44 mg/mL of Mg,6.28 μg/mL of Mn,2.98 μg/mL of Zn,7.50 μg/mL of Fe,and 0.074 μg/mL of Se in ash removal solution of acetic acid.It further reveals that except the contents of Zn and Se,the other beneficial elements＇ contents are higher than those in ash removal solution of 0.44 mol/L hydrochloric acid,and the effect of arsenic removal is better than that by using hydrochloric acid.The orthogonal test for acetic acid reveals that the best ash removal effect is achieved when the concentration of acetic acid solution is 0.6 mol/L,the removal time is three days,and the ratio of raw material to acetic acid is 1∶15.It is concluded that acetic acid may be used in pretreatment of ash removal from body wall of Asterina pectinifera and beneficial for collagen extraction and reutilization of ash removal solution of acetic acid.
