Abstract

The effect of the gamma-irradiated extract of rosemary and butylated hydroxyanisole (BHA) antioxidant on sensory, chemical and microbiological changes of rainbow trout fillets stored at 4 ± 1°C was investigated for 16 days. The fillets were divided into: control (C), 750 and 1500 rosemary extract (RE) (immersed in 750 and 1500 ppm rosemary extract); 250 and 500 gamma-irradiated rosemary (GIR), (immersed in 250 and 500 ppm gamma-irradiated rosemary) and 250 and 500 BHA (immersed in 250 and 500 ppm BHA). The shelf life of fillets was reported to be 8 days for C, and 12 days for 500 GIR group according sensory, microbiological and chemical parameters. The pH, peroxide value (PV), total volatile basic nitrogen (TVB-N), free fatty acid (FFA), thiobarbituric acid (TBA), psychrotrophic counts (PTC), and total viable aerobic bacterial counts (TVC) values were 7.62 ± 0.21, 17.17 ± 1.6, 51.07 ± 1.1, 6.05 ± 0.13, 3.42 ± 0.18, 12.03 ± 0.19, and 13.16 ± 0.16 respectively for C group and also, 7.42 ± 0.16, 15.2 ± 1.7, 42.5 ± 1.5, 4.48 ± 0.39, 2.59 ± 0.15, 9.98 ± 0.15, and 10.5 ± 0.15 respectively for 500 GIR group. Finally, the following trend in effectiveness was reported: gamma-irradiated rosemary PBS extract > BHA > rosemary PBS extract.

γ辐照迷迭香对虹鳟鱼鱼片冷藏品质的影响

研究了γ辐照迷迭香提取物和丁基羟基茴香醚(BHA)抗氧化剂对虹鳟鱼鱼片在4±1℃保存16 d后的感官、化学和微生物变化的影响。鱼片分为:对照(C)、750和1500迷迭香提取物(RE)(浸泡在750和1500 ppm迷迭香提取物中);250和500 γ辐照的迷迭香(GIR)(浸在250和500 ppm γ辐照的迷迭香中)和250和500 BHA(浸在250和500 ppm BHA中)。根据感官、微生物和化学参数，C组的鱼片保质期为8天，500 GIR组的鱼片保质期为12天。pH值、过氧化值(PV)、总挥发性基本氮(TVB-N)、游离脂肪酸(FFA)、硫代巴比土酸(稍后通知),psychrotrophic计数(PTC),和可行的有氧细菌总数量(TVC)值分别为7.62±0.21、17.17±1.6、51.07±1.1、6.05±0.13、3.42±0.18、12.03±0.19、13.16±0.16分别为C组,7.42±0.16,15.2±1.7,42.5±1.5,4.48±0.39,2.59±0.15,9.98±0.15,10.5±0.15分别为500 GIR集团。结果表明:γ辐照迷迭香PBS提取物> BHA >迷迭香PBS提取物。
