Abstract

ABSTRACTBy comparing the cytochrome b fragment sequences of sablefish and 16 varieties susceptible to adulteration, a real-time polymerase chain reaction (PCR) method was established to detect sablefish-derived components. The PCR method was used to analyze commercial products. The method developed was highly specific without any cross-reaction in the other 16 species and with a limit of detection for deoxyribonucleic acid (DNA) of 0.002 ng µL−1 for sablefish. In addition, the mixed muscle tissues were detected at as low as 0.01 g kg−1. The applicability of the PCR method to 50 commercial prepackaged products revealed the accuracy of this method.KEYWORDS: Sablefishreal-time polymerase chain reactionauthenticationcytochrome b gene Disclosure statementThe authors declare no competing financial interest.Data availability statementThe datasets used and/or analyzed during the current study are available from the corresponding author on reasonable request.Additional informationFundingThis work was supported by the National Key Research and Development Program of China under Grant [number 2019YFC1604702]; National Key Research and Development Program of China under Grant [number 2016YFF0201805]; Central Public-interest Scientific Institution Basal Research Fund, CAFS under Grant [2020TD71]; and Central Public-interest Scientific Institution Basal Research Fund, CAFS under Grant [2021JC01].

实时聚合酶链反应(Real-Time Polymerase Chain Reaction, PCR)鉴定商业海产品中黑鲈(Anoplopoma fibria)的建立与评价
摘要通过比较黑鱼和16个易掺假品种的细胞色素b片段序列,建立了实时聚合酶链反应(PCR)检测黑鱼来源成分的方法。PCR法用于商业产品分析。该方法特异性强,对其他16个物种无交叉反应,对黑鱼脱氧核糖核酸(DNA)的检出限为0.002 ngµL−1。此外,低至0.01 g kg−1时可检测到混合肌肉组织。PCR方法对50种商业预包装产品的适用性表明了该方法的准确性。关键词:黑鲈实时聚合酶链反应鉴定细胞色素b基因披露声明作者声明无竞争性经济利益。数据可用性声明当前研究中使用和/或分析的数据集可根据通讯作者的合理要求提供。项目资助:国家重点研发计划项目[no . 2019YFC1604702];国家重点研发计划项目[no . 2016YFF0201805];中央公益性科研机构基础研究基金[2020TD71];中央公益性科研机构基础研究基金[2021JC01]。

期刊介绍: The Journal of Aquatic Food Product Technology publishes research papers, short communications, and review articles concerning the application of science and technology and biotechnology to all aspects of research, innovation, production, and distribution of food products originating from the marine and freshwater bodies of the world. The journal features articles on various aspects of basic and applied science in topics related to: -harvesting and handling practices- processing with traditional and new technologies- refrigeration and freezing- packaging and storage- safety and traceability- byproduct utilization- consumer attitudes toward aquatic food. The Journal also covers basic studies of aquatic products as related to food chemistry, microbiology, and engineering, such as all flora and fauna from aquatic environs, including seaweeds and underutilized species used directly for human consumption or alternative uses. Special features in the journal include guest editorials by specialists in their fields and book reviews covering a wide range of topics.
