The aquaculture production of common carp (Cyprinus carpio) is one of the biggest on a global scale, although European production represents a minor part. Thus, common carp is a little-exploited, low-cost, and highly nutritious food source. For development of new quality products that have customers’ appeal and are safe, a combination of traditional and novel technologies can be used. However, good quality raw material is of basic importance for further processing and final product quality. Fish microbiota have a major role in fish spoilage and as potential human pathogens. To diminish the negative impact of the microbiota on fish, different methods and technologies can be used. The important steps before the final product processing in the production of common carp products include purging, transport, pre-slaughter storage, slaughter method, bleeding, cleaning, desliming, descaling, and gutting. The most important factor in fish spoilage prevention is chilling, although to assure longer freshness and shelf-life, the concept of hurdle technology should be used. Many preservation and packaging techniques have been developed for fish products, but not all have been researched for common carp products. This review aims to identify the gaps in research, knowledge, and practice for the microbiological aspects that impact upon the production of high-quality common carp food products. 相似文献

This study investigated the possibility of using a finishing feeding strategy and to apply a dilution model for the calculation of the content of fatty acids (FA) in farmed brook char (Salvelinus fontinalis). Four duplicate groups of fish with an initial weight 153.3 ± 4.9 g?1 were kept in a flow-through system for 135 days, during which they more than triplicated their weight. Control groups were fed the same unmodified commercial diet with 100 % fish oil (FO) or with 60 % fish oil and 40 % rapeseed oil (RO) mixture. Two groups were fed by RO diet followed by 45 (RO:45FO) and 90 (RO:90FO) days of FO diet, respectively, at the end of the growing period. The fillet FA composition at the end of the experiment corresponded with the FA composition of the lipid source in the diet for the tested groups. A significant (p < 0.05) impact on FA composition with a decreasing tendency in the representation of n-3 HUFA with a prolonged feeding period with the RO diet was observed. The application of a dilution model enabling the prediction of the content of a given fatty acid in a given time was successfully performed. 相似文献

Evaluation of the effect of dietary sesamin on white muscle lipid composition of common carp (Cyprinus carpio L.) juveniles

Two different basic diets with defatted fishmeal as a protein source and either only linseed oil or a mixture of linseed and sunflower oil as a lipid source designed to have two different n‐3/n‐6 ratios (1.21 – CL group; 0.32 – CM group) were produced. Each diet was then used with or without added sesamin (0.58 g 100g?1). One hundred and forty‐four individuals were fed in triplicated groups for 63 days until their weight had doubled. No influence of dietary sesamin on growth, mortality or on the white muscle lipid content of the fish was found. Added sesamin significantly decreased the content of PLs and increased the cholesterol content in the CM group. No effect was found in the total lipid fatty acid composition but there was found a significantly lower content of saturated fatty acids and 20:5n‐3 in PLs and of 22:6n‐3 in triacylglycerols in the sesamin supplemented CL group. These and other differences show either a tendency of lower long chain n‐3 fatty acids biosynthesis or their higher use in β‐oxidation in sesamin‐supplemented groups. We conclude that sesamin in this experiment had no substantial positive impact on the lipid metabolism of juvenile carp. 相似文献

Proximate composition and amino and fatty acid profiles of peled fillets of both sexes reared in a pond-based system (PS) and intensively cultured in a recirculating aquaculture system (RS) were compared. Significantly higher values of dry matter, fat, and caloric value were found in RS fish, irrespective of sex. Fish from the PS group showed a higher percentage of saturated fatty acids and polyunsaturated fatty acids (PUFA) than those of the RS group. Percentages of n-3 PUFA were lower in the RS group compared to the PS group, while percentages of n-6 PUFA were higher in RS, irrespective of sex. The ratio of n-3:n-6 PUFA was significantly higher for the RS group. Fillets of the PS group showed significantly higher EPA and DHA percentages compared to RS fish. Significant differences were found in amino acid profile, with the PS group showing higher content, especially of serine, glutamic acid, methionine, leucine, and lysine. 相似文献
