In this study, active biopolymer trays, being part of the biodegradable packaging, were developed and characterised. The aim of our research was to determine how active packaging (trays + films) affects the quality of salmon storage. The trays had high antioxidant potential and were biodegradable, however, they limited germination and seed growth, which may have been caused by the low pH of the material. Furthermore, the applied packaging demonstrated a potential possible inhibitory effect on the accumulation of biogenic amines and the growth of microorganisms responsible for the spoilage of salmon fillets. Compared to the control group, fillets stored in the tested pack had a 19% lower total bacteria count on the 6th day of storage. The innovative packing is easily biodegradable and prolongs the shelf-life of salmon fillets, therefore, it shows promise as a packaging material for perishable food products.
在这项研究中，我们开发并表征了作为可生物降解包装一部分的活性生物聚合物托盘。我们研究的目的是确定活性包装（托盘+薄膜）如何影响三文鱼的储存质量。这些托盘具有高抗氧化潜力和生物降解性，但它们限制了发芽和种子生长，这可能是由于材料的低 pH 值造成的。此外，所应用的包装对生物胺的积累和导致三文鱼鱼片变质的微生物的生长表现出潜在的抑制作用。与对照组相比，在测试包装中储存的鱼片在第 6 天的储存期内总细菌数减少了 19%。这种创新包装易于生物降解，并延长了三文鱼鱼片的保质期，因此有望成为易腐食品的包装材料。
