Abstract
Common carp is a fish species of economic importance in China; traditionally it is mostly salt-fermented. In the fermenting process, the bacterial community of spontaneously fermented fish is important for its flavour and quality. However, very few studies have been conducted about the relationship between bacterial community and development of flavour involved in the salt-fermentation of carp. Therefore, we explored this relationship by determining the flavour components, including amino acids, and changes in volatile flavour and bacterial metabolite. Samples were taken during fermentation on the days 0, 10, 20, 30, 40 and 50. The second-generation 16S recom-binant DNA (rDNA) sequencing was performed to analyze the composition of bacteria. Contents of amino acids were determined by reverse-phase high-performance liquid chromatography combined with ultraviolet detection. The volatile components were analyzed with solid-phase microextraction–gas chromatography-mass spectrometry. Enterococcus, Lactobacillus, Lactococcus, Leuconostoc, and Staphylococcus were the dominant bacteria. The bidirectional orthogonal partial least squares approach was used to analyze the correlation between bacterial succession and flavour component dynamics. This study would help to better understand the role of bacteria in the fermented fish meat flavour and support the industrial production of fermented fish.
期刊介绍:
''Quality Assurance and Safety of Crops & Foods'' is an international peer-reviewed journal publishing research and review papers associated with the quality and safety of food and food sources including cereals, grains, oilseeds, fruits, root crops and animal sources. It targets both primary materials and their conversion to human foods. There is a strong focus on the development and application of new analytical tools and their potential for quality assessment, assurance, control and safety. The scope includes issues of risk assessment, traceability, authenticity, food security and socio-economic impacts. Manuscripts presenting novel data and information that are likely to significantly contribute to scientific knowledge in areas of food quality and safety will be considered.
''Quality Assurance and Safety of Crops & Foods'' provides a forum for all those working in the specialist field of food quality and safety to report on the progress and outcomes of their research.
