摘要
目前食品工业中所用水凝胶大多为天然聚合物,机械性能差,因水分含量高易被微生物污染,难以满足使用需求。近年来,由天然与合成聚合物复合或者改性天然聚合物制备的负载活性物质的新型复合水凝胶在食品领域中应用日益广泛。文章从复合水凝胶的制备方法入手,介绍了其在食品包装材料、脂肪和淀粉替代、生物活性分子递送、微生物的快速检测等方面的应用现状,并对复合水凝胶在食品行业中的发展趋势进行了展望。
At present,most hydrogels used in the food industry are natural polymers,with poor mechanical properties and high moisture content,which is easy to be contaminated by microorganisms,making it difficult to meet the use needs.In recent years,new composite hydrogels loaded with active substances prepared from natural and synthetic polymers or modified natural polymers have been increasingly used in the food field..Starting from the preparation method of composite hydrogels,this paper introduces its application status in food packaging materials,fat and starch substitution,bioactive molecule delivery,rapid detection of microorganisms,and prospects the development trend of composite hydrogels in the food industry.
