A tannins‐rich chestnut extract was used to enhance the antioxidant and antibacterial properties of chitosan‐based film materials. The favourable mechanical properties of the novel material enabled its application in the preparation of the sachets that were used for packing and storage of filled fresh pasta. The fresh pasta ageing progressed in conventional refrigerated storage conditions of 8 °C with 60 ± 2% relative humidity in the absence of light for 60 days. The rapid moisture mobility between a starchy food and sachets during the first 9 days of storage induced retrogradation of the fresh pasta, whereby total phenolic content show dependency on moisture throughout the shelf life. Active components within the sachet prevented microbial growth on the food surface during the entire 60 days.

活性壳聚糖-栗子提取物薄膜，用于新鲜面食的包装和存储

富含单宁的板栗提取物可增强基于壳聚糖的薄膜材料的抗氧化和抗菌性能。新型材料的良好机械性能使其可用于制备用于包装和储存新鲜意大利面的小袋。新鲜面食的老化过程是在8°C，相对湿度为60±2％的常规冷藏存储条件下，没有光照的情况下进行60天。在储存的前9天中，淀粉类食品和小袋之间的快速水分迁移会引起新鲜面食的回生，从而总酚含量在整个货架期内都显示出对水分的依赖性。在整个60天内，小袋中的活性成分可防止微生物在食品表面上生长。
