Cured Spanish mackerel has a promising market owing to its nutritious nature as well as ease of transportation and preservation. However, the nutritional and flavor formation mechanism of Spanish mackerel after curing and drying is unclear. To overcome this problem, the effects of different processing conditions on the free amino acid, microbial community, and flavor of Spanish mackerel were explored. Staphylococcus and Cobetia are the main microorganisms in cured mackerel and are closely associated with the formation of their quality. Compared with fresh mackerel, cured mackerel contains increased levels of protein, fat, and chloride, contributing to its distinctive flavor. The contents of free amino acids in the BA64 group were substantially higher than those in other groups, particularly the contents of threonine, glycine, and tyrosine. These findings will contribute to the development of high-quality cured Spanish mackerel products and cured aquatic products.

Article Synopsis
  • Climate change, especially extreme weather, impacts population connectivity in migratory species, making it tough to study these effects due to complex migration patterns.* -
  • Research on Japanese Spanish mackerel, focusing on their otolith (ear stone) biogeochemistry during a significant El Niño event, showed increased elemental concentrations that indicate changes in population connectivity along China’s coast.* -
  • The study suggests that extreme climate events like El Niño can significantly alter migratory patterns and connectivity in fish populations, highlighting the potential of otolith biogeochemistry as a tool for understanding these impacts.*

Parasitism involves diverse evolutionary strategies, including adaptations for blood feeding, which provides essential nutrients for growth and reproduction. (Polyopisthocotyla: Microcotylidae), an ectoparasitic flatworm, infects the gills of gilthead seabream (), significantly affecting fish health, welfare and Mediterranean cage farm profitability. Despite its impact, limited information exists on its feeding behaviour.

Dynamic changes in the gel properties, microbial community, and volatile flavor profile of Spanish mackerel () sausages inoculated with CY1-2.

College of Food Science and Engineering, Bohai University, National and Local Joint Engineering Research Center of Storage, Processing and Safety Control Technology for Fresh Agricultural and Aquatic Products, Jinzhou, Liaoning, 121013, China.

Spanish mackerel is an important economic fish species in China, but corruption undermines its overall economic value. Fermentation serves as a crucial technique for preserving perishable fish in developing countries. This study aimed to examine the dynamic changes in the gel properties, physicochemical properties, microbial diversity, and volatile flavor compounds (VFCs) of Spanish mackerel sausages inoculated with CY1-2 during fermentation.

Article Synopsis
  • Researchers explored how adding soy protein isolate-inulin conjugates (SPI-inulin) affects the gel properties of Spanish mackerel myofibrillar protein (MP).
  • The addition of these conjugates significantly improved the gel strength (from 35.18 g·cm to 41.90 g·cm) and water-holding capacity (from 36.80% to 52.67%).
  • The study found changes in the protein's molecular structure, such as decreased α-helix and increased β-sheet content, while also suggesting that using SPI-inulin conjugates could enhance the quality of surimi products.
