【摘要】 以壳聚糖为载体,甲醛浸泡过的黄鱼、人血清白蛋白为材料,研究一种壳聚糖法固定黄鱼中甲醛的方法。本文对影响固定化的关键因素:戊二醛浓度、甲醛-人血清白蛋白(FA-HSA)用量、吸附温度等展开研究,以FA-HSA吸附率为指标,分别进行单因素实验和正交实验,探索其固定化最佳条件。实验结果表明,当戊二醛浓度为5%,FA-HSA用量为14 mL,吸附温度为42℃,吸附时间为4h时,FA-HSA的吸附量为最大值,且达到59.2%。更多还原

【Abstract】 With Chitosan as a carrier,a method for immobilizing formaldehyde residue in yellow croaker was developed.Effects of several key factors,including glutaraldehyde concentration,the amount of FA-HSA,adsorption temperature and so on,on immobilization were investigated taking the adsorption rate of FA-HSA as the indicators.Through single factor experiments and orthogonal test,the best condition of formaldehyde immobilization on chitosan were determined as: glutaraldehyde concentration 5%,the amount of FA-HSA 14mL,adsorption temperature 42 ℃ and the adsorption time 4 h.Under the optimum immobilization conditions,the adsorption rate of FA-HSA reached the highest rate of 59.2%.更多还原
