Abstract

Effects of modified atmosphere packaging (MAP) in combination to UV-C radiation on rainbow trout fillets were examined. The samples were submitted to two treatments: (T1) aerobic package; (T2) MAP+UV-C radiation (80% CO₂/20% N_2; 106.32mJ/cm²) and were analyzed daily for microbiological (mesophilic and psychrotrophic count) and chemical (biogenic amines) parameters. MAP+UV-C radiation (T2) promoted lag phase formation and lower number of colonies in the stationary phase as well as retarded cadaverine production during storage time. MAP+UV-C radiation retard microbial growth and delay chemical changes enhancing the shelf life of rainbow trout fillets by at least twice.

气调包装和UV-C辐射对虹鳟鱼保质期的影响

研究了改性大气包装(MAP)对虹鳟鱼鱼片UV-C辐射的影响。样品进行两种处理:(T1)有氧包装;(T2) MAP+UV-C辐射(80% CO2/20% N2;106.32mJ/cm2)，每天分析微生物(嗜温和嗜冷计数)和化学(生物胺)参数。MAP+UV-C辐射(T2)促进了静止期的滞后期形成和菌落数量的减少，并延缓了储存期间尸胺的产生。MAP+UV-C辐射延缓微生物生长，延缓化学变化，使虹鳟鱼片的保质期延长至少两倍。
