摘要
α-硫辛酸(ALA)及其还原态二氢硫辛酸(DHLA)在生物体内的转化过程组成了良好的自由基清除剂,壳聚糖(CS)具有良好的成膜性能和生物相容性。以ALA/DHLA为模板分子,CS为功能单体,制备温敏型ALA-CS分子印迹聚合物(MIPs)膜或将其固载于塑料膜中,可以有效发挥温敏型化合物的特性,开发防止或延缓食品劣变的活性包装材料。本文综述了基于分子印迹膜的抗氧化型包装材料的研究进展,并对其未来发展进行了展望。
The mutual transformation process of α-lipoic acid (ALA) and its reduction state called dihydrolipoic acid (DHLA) constitutes a good free radical scavenger in the organism. Biopolymer chitosan (CS), meanwhile, has excellent membrane-forming ability and biocompatibility. Therefore, the preparation of ALA-CS molecularly imprinted polymers (MIPs) with ALA/DHLA as template molecules and CS as functional monomer or the immobilization of MIPs on plastic films will prevent or delay the food deterioration by taking advantage of the characteristics of temperature-sensitive compounds MIPs. A review on the research progress in anti-oxidative and thermo-sensitive lipoic acid molecularly imprinted polymers was presented and the prospect of these MIPs were proposed in this paper.
