摘　　要：随着人们对食品安全问题的重视,生物基包装材料作用于果蔬保鲜现已成为研究热点之一,壳聚糖来源广泛、绿色安全,作为一种天然的生物涂膜保鲜剂具有良好的抗氧化性和抑菌活性,在果蔬保鲜中具有较好的应用前景。文章以草莓为实验模型,系统梳理了草莓保鲜技术,重点综述了壳聚糖-植物提取物、壳聚糖-多糖、壳聚糖-酸涂膜材料与技术在草莓保鲜包装领域中的应用。通过对草莓采后及贮藏中失重、硬度、可溶性固形物、腐烂率等生理指标的概述对壳聚糖基涂膜在草莓保鲜中的应用研究进行分析和总结,同时对果蔬保鲜的未来发展进行了展望,以期为壳聚糖基涂膜在果蔬中的广泛应用提供参考。With people’s attention to food safety issues,the effect of bio-based packaging materials on fruit and vegetable preservation has become one of the research hotspots. Chitosan has a wide range of sources,green and safe.As a natural biological coating preservative,chitosan has good antioxidant and antibacterial activity,which has a good application prospect in fruit and vegetable preservation. Taking strawberry as the experimental model,this paper systematically sorted out strawberry preservation technology,focusing on the application of chitosan-plant extract,chitosan-polysaccharide,chitosan-acid coating materials and technologies in strawberry preservation packaging field,analyzed and summarized the application of chitosan-based coating in strawberry preservation based on the overview of the physiological indexes such as weight loss,hardness,soluble solids and decay rate during postharvest and storage of strawberry,and prospected the future development of fruit and vegetable preservation,in order to provide references for the extensive application of chitosan-based coating in fruits and vegetables.
