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].
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.
