Abstract
Codfish is a commercially important species of sea fish and plays an important role in the world fishery. In our study, two loop-mediated isothermal amplification (LAMP) assays (real-time fluorescence LAMP and visual LAMP) were established for the identification of three cod species in Gadidae (Gadus morhua, Gadus macrocephalus and Melanogrammus aeglefinus). 12S rDNA gene was used to design primers to distinguish the Gadidae and non-Gadidae species, and the mitochondrial Cytb gene was selected for discrimination of three cod species. After optimization, the 12S rDNA system and species-specific systems performed well, and target cod DNA could be detected in single or mixed samples. In the species-specific systems, the absolute limit of detection (LODa) of three cod species were 285, 37 and 197 pg/μL, and the relative limit of detection (LODr) reached to 1%, 0.1% and 1%, respectively. In the 12S rDNA system, the LODa of three cod species were 28.5, 37 and 19.7 pg/μL, respectively, and the LODr reached to 0.1%. Through the detection of 13 commercial cod products, the LAMP systems can detect cod contents in raw materials and deep-processed products as well. It indicated that the methods developed in this study have strong practicability and can meet the needs of routine testing.

[PMID: 29571456 DOI: 10.1016/j.foodchem.2018.02.056] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2017] [Revised: 09/10/2017] [Accepted: 02/11/2018] [Indexed: 10/18/2022]
Abstract
Skates and rays are commercially important fish in South Korea, and among them, Beringraja pulchra has the highest economic value. However, the similar morphological traits among skates and rays are often exploited for seafood fraud. Here, we designed both Beringraja pulchra-specific and skate-universal primer sets, capable of detecting short sequences in the cytochrome oxidase subunit I gene, and developed highly sensitive and reliable quantitative real-time PCR (qPCR) assays to differentiate between Beringraja pulchra and other skate and ray species. AΔCq method based on differences in the amplification efficiency was developed, validated, and then used to confirm the presence of Beringraja pulchra in twenty-six commercial skate products. The averageΔCq value obtained for other skate species (18.94 ± 3.46) was significantly higher than that of Beringraja pulchra (1.18 ± 0.15). For on-site applications, we developed an ultra-fast qPCR assay, allowing for completion of the entire analytical procedure within 30 min.

Abstract
Squids are distributed worldwide, including many species of commercial importance, and they are often made into varieties of flavor foods. The rapid identification methods for squid species especially their processed products, however, have not been well developed. In this study, quantitative real-time PCR (qPCR) systems based on specific primers and TaqMan probes have been established for rapid and accurate identification of four common squid species (Ommastrephes bartramii, Dosidicus gigas, Illex argentinus, Todarodes pacificus) in Chinese domestic market. After analyzing mitochondrial genes reported in GenBank, the mitochondrial cytochrome b (Cytb) gene was selected for O. bartramii detection, cytochrome c oxidase subunit I (COI) gene for D. gigas and T. Pacificus detection, ATPase subunit 6 (ATPase 6) gene for I. Argentinus detection, and 12S ribosomal RNA (12S rDNA) gene for designing Ommastrephidae-specific primers and probe. As a result, all the TaqMan systems are of good performance, and efficiency of each reaction was calculated by making standard curves. This method could detect target species either in single or mixed squid specimen, and it was applied to identify 12 squid processed products successfully. Thus, it would play an important role in fulfilling labeling regulations and squid fishery control.
