the effect of glazing based on saponin free quinoa chenopodium quinoa extract on the lipid quality of frozen fatty fish
Lwt - Food Science and Technology, 2018Co-Authors: Marcos Trigo, Alicia Rodriguez, Gretel Dovale, Alexis Pasten, Antonio Vegagalvez, Santiago P AubourgAbstract:Abstract This study focussed on the rancidity stability of frozen fatty fish. Its basic objective was to investigate the effect of a glazing system including a saponin-free quinoa (Chenopodium quinoa) extract during the frozen storage of Atlantic mackerel (Scomber scombrus). For it, two different concentrations of 80% aq. (v/v) ethanol quinoa extracts (0.45 and 1.36 g lyophilised quinoa L−1 solution, respectively) were tested and compared with two control treatments (water glazing and non-glazing conditions). Chemical and sensory changes were monitored for a 8-month frozen storage. An inhibitory effect (p

lipid hydrolysis and oxidation development in frozen mackerel Scomber scombrus effect of a high hydrostatic pressure pre treatment
Innovative Food Science and Emerging Technologies, 2013Co-Authors: Manuel Vazquez, Antonio J Torres, Jose Manuel Gallardo, Jorge A Saraiva, Santiago P AubourgAbstract:Abstract This work focused on assessing lipid damage during the storage of frozen Atlantic mackerel ( Scomber scombrus ) subjected to a high hydrostatic pressure (HHP) treatment (150, 300, 450 MPa with holding times of 0.0, 2.5, and 5.0 min) prior to freezing. The extent of lipid hydrolysis (free fatty acids) and oxidation (peroxide, thiobarbituric acid reactive substance and fluorescent and browning compound formation) as well as the polyene content were analysed during 3 months of accelerated storage at − 10 °C. A marked inhibition (p 0.05) in the content of primary and secondary oxidation compounds were observed. Industrial relevance Frozen storage of fatty fish species is known to be strongly limited by the lipid damage development, being this an important drawback for its commercialisation as such or for its further employment as raw material in other kinds of processing (canneries, smoking, etc.). Present research provides novel and valuable information concerning the employment of high hydrostatic pressure technology to inhibit lipid damage (hydrolysis and oxidation) during the further frozen storage of mackerel ( Scomber scombrus ). Thus, pressure (150, 300 and 450 MPa) and holding time (0.0, 2.5 and 5.0 min) conditions tested showed to be profitable to partially inhibit lipid damage.

PERMANENT GENETIC RESOURCES: Isolation and characterization of nine microsatellite loci from the chub mackerel, Scomber japonicus (Perciformes, Scombridae).
Molecular ecology resources, 2008Co-Authors: N. Yagishita, T. KobayashiAbstract:The stock abundance of the chub mackerel Scomber japonicus - a very important species for fisheries, particularly in Japan - in the Pacific Ocean off Japan has remained at a low level. For studying the population genetics of the chub mackerel, we isolated nine polymorphic microsatellite loci (12-31 alleles/locus; expected heterozygosity, 0.762-0.983) from this species. Cross-species amplification indicated that eight of the nine microsatellite loci in the blue mackerel S. australasicus were polymorphic and functional.

evolutionary relatedness of mackerels of the genus Scomber based on complete mitochondrial genomes strong support to the recognition of atlantic Scomber colias and pacific Scomber japonicus as distinct species
Gene, 2010Co-Authors: Gaetano Catanese, Manuel Manchado, Carlos InfanteAbstract:Mackerels of the genus Scomber are commercially important species, but their taxonomic status is still controversial. Although previous phylogenetic data support the recognition of Atlantic Scomber colias and Pacific Scomber japonicus as separate species, it is only based on the analysis of partial mitochondrial and nuclear DNA sequences. In an attempt to shed light on this relevant issue, we have determined the complete mitochondrial DNA sequence of S. colias, S. japonicus, and Scomber australasicus. The total length of the mitogenomes was 16,568 bp for S. colias and 16,570 bp for both S. japonicus and S. australasicus. All mitogenomes had a gene content (13 protein-coding, 2 rRNAs, and 22 tRNAs) and organization similar to that observed in Scomber scombrus and most other vertebrates. The major noncoding region (control region) ranged between 865 and 866 bp in length and showed the typical conserved blocks. Phylogenetic analyses revealed a monophyletic origin of Scomber species with regard to other scombrid fish. The major finding of this study is that S. colias and S. japonicus were significantly grouped in distinct lineages within Scomber cluster, which phylogenetically constitutes evidence that they may be considered as separate species. Additionally, molecular data here presented provide a useful tool for evolutionary as well as population genetic studies.

Phylogenetic differentiation between Atlantic Scomber colias and Pacific Scomber japonicus based on nuclear DNA sequences
Genetica, 2007Co-Authors: Carlos Infante, Aniela Crespo, Eugenia Zuasti, Enrique Blanco, Manuel ManchadoAbstract:In the classical taxonomy, three Scomber species are distinguished: S. scombrus , S. australasicus , and S. japonicus . Yet, some fish taxonomists have recently recognized Scomber colias , inhabiting the Atlantic Ocean, as a separate species from S. japonicus , distributed in the Pacific Ocean. Such proposal was based on significant mitochondrial DNA divergence as well as great phenotypic variation among individuals from these two ocean basins. However, in the absence of nuclear DNA data this issue remains still controversial. In this study, a phylogenetic analysis of nuclear 5S rDNA sequences was performed. A total of 30 individuals of S. colias collected in the Atlantic and 34␣specimens of S. japonicus from the Pacific were characterized. Moreover, nine individuals of Pacific S.␣australasicus and eight of Atlantic S. scombrus were included. Maximum likelihood, maximum parsimony, and neighbor-joining analyses revealed the presence of␣two well-supported distinct clades corresponding to S. colias and S. japonicus , respectively. Altogether, morphologic and genetic data are in agreement with the recognition of two different species, S. colias in the Atlantic, and S. japonicus in the Pacific.

pcr based methodology for the authentication of the atlantic mackerel Scomber scombrus in commercial canned products
Food Research International, 2006Co-Authors: Carlos Infante, Aniela Crespo, Eugenia Zuasti, Marian Ponce, Laura Perez, Victoria Funes, Gaetano Catanese, Manuel ManchadoAbstract:A multiplex-PCR assay for the authentication of the Atlantic mackerel Scomber scombrus in commercial canned products has been developed. This novel method consists of a S. scombrus-specific fragment (123 bp) corresponding to the mitochondrial NADH dehydrogenase subunit 5, and a positive amplification control corresponding to the small rRNA 12S subunit (188 bp). The system was assayed using six different canned products labeled as S. scombrus. We observed a positive identification in all samples, revealing this methodology as a potential molecular tool for direct application in the authentication of S. scombrus canned products.
