改性壳聚糖及其对贝类提取液重金属脱除的研究进展

Research progress in modified chitosan and its application to remove heavy metal of shellfish extraction

  • 摘要: 壳聚糖是天然生物高分子化合物甲壳素的脱乙酰基产物,具有来源广泛、无毒无害、易生物降解的特点,分子中含有大量的氨基和羟基等功能基团,对重金属离子具有很好的吸附能力。通过对壳聚糖进行适当的改性,可以提高壳聚糖的稳定性和选择吸附性。本文介绍了壳聚糖的改性方法,综述了壳聚糖及其衍生物在食品行业中应用,并归纳了其在脱除贝类提取液中重金属方面的研究进展。 

     

    Abstract: Chitosan is obtained by N-deacetylation of chitin, which is extensive, nontoxic and readily biodegradable.It has good adsorption capacity for heavy metal ions because there are a lot of functional groups such as amino and hydroxyl in its structure. It is available to enhance the stability and selective adsorption of chitosan by appropriate modification. In this article, chitosan modification methods were reported. The application of chitosan and its derivatives in food industry was summarized and its use in heavy metal removal from shellfish extraction was reviewed.
