Abstract

The effect of antioxidant extracted from bamboo leaves (AOB) on the quality of sturgeon fillets during chilled storage was examined via three parameters: total volatile basic nitrogen (TVB-N), pH and bacterial community composition. The samples treated with 0.05% (w/v) AOB exhibited the best quality, as evidenced by retarding both pH changes and the production of TVB-N. Pseudomonas and Aeromonas were the dominant indigenous bacteria present in fresh sturgeon fillets, whereas the presence of Janthinobacterium and Pedobacter increased gradually throughout the storage process. A significant (P < 0.05) positive correlation was observed between the pH, TVB-N and two bacterial groups, Pseudomonas and Pedobacter. Based on the TVB-N assessment, the fillets began to decompose at the ninth day in the control samples and the twelfth day in the 0.05% AOB-treated samples. The relative abundance of Pseudomonas, Janthinobacterium and Pedobacter in the 0.05% AOB treatment group was lower than in the control group. Therefore, our results showed that treatment with 0.05% AOB improved the quality of fillets during the box-packaged storage.

竹叶抗氧化剂对4°C箱包装鲟鱼鱼片品质的影响

通过挥发性碱性氮(TVB-N)、pH值和细菌群落组成3个参数考察了竹叶抗氧化剂(AOB)对鲟鱼鱼片冷藏品质的影响。0.05% (w/v) AOB处理的样品质量最好，可以延缓pH变化和TVB-N的生成。假单胞菌和气单胞菌是新鲜鲟鱼鱼片中主要的本地细菌，而在整个储存过程中，Janthinobacterium和Pedobacter的存在逐渐增加。pH、TVB-N与假单胞菌(Pseudomonas)和土杆菌(Pedobacter)菌群呈显著正相关(P < 0.05)。根据TVB-N评价，对照样品的鱼片在第9天开始分解，0.05% aob处理样品的鱼片在第12天开始分解。0.05% AOB处理组假单胞菌、Janthinobacterium和Pedobacter的相对丰度低于对照组。因此，我们的研究结果表明，0.05%的AOB处理提高了盒装鱼片的质量。

期刊介绍： ''Quality Assurance and Safety of Crops & Foods'' is an international peer-reviewed journal publishing research and review papers associated with the quality and safety of food and food sources including cereals, grains, oilseeds, fruits, root crops and animal sources. It targets both primary materials and their conversion to human foods. There is a strong focus on the development and application of new analytical tools and their potential for quality assessment, assurance, control and safety. The scope includes issues of risk assessment, traceability, authenticity, food security and socio-economic impacts. Manuscripts presenting novel data and information that are likely to significantly contribute to scientific knowledge in areas of food quality and safety will be considered. ''Quality Assurance and Safety of Crops & Foods'' provides a forum for all those working in the specialist field of food quality and safety to report on the progress and outcomes of their research.
