Abstract

SUMMARYResearch backgroundIt is desirable to increase the consumption of pelagic fish rich in long-chain omega-3 fatty acids. Partial replacement of traditionally used white fish species by pelagic fish will increase the content of omega-3 fatty acids, and thus improve the nutritional value but it may also affect the consumer acceptance. The aim of this study is to assess the physicochemical and sensory quality of novel fish cake prototypes prepared from haddock and mackerel mince.Experimental approachFillets of haddock and Atlantic mackerel were used as raw material for preparation of fish cakes. The fish fillets were minced, mixed together (in haddock/mackerel mass ratio of 100:0, 75:25 and 50:50%) with salt, potato starch, pepper and full fat milk. Physicochemical and sensory analyses were further performed.Results and conclusionsThe fatty acid composition analysis showed that the recommended daily intake of 250 mg of eicosapentaenoic acid and docosahexaenoic acid can easily be reached by consumption of fish cakes enriched with mackerel. The oxidation levels of all fish cakes were low in terms of peroxide value and thiobarbituric acid reactive substance assay (TBARS). Fish cakes prepared with higher mass fraction of mackerel mince (>50%) had significantly (p<0.05) softer texture than other fish cakes due to higher amount of fat in their formulations. At the same time, these fish cakes were significantly darker than haddock-based (>50%) fish cakes due to higher myoglobin content in the fish muscle. Moreover, fish cakes with higher amount of mackerel mince had increased yellowness due to the accumulation of water-soluble (r=0.990, p<0.05) and fat-soluble (r=0.976, p<0.05) TBARS. Metabolites relevant for taste and quality were quantified by using 1H nuclear magnetic resonance (NMR) spectroscopy. The mass fraction of anserine, trimethylamine oxide and β-alanine decreased, while the mass fraction of histidine, glutamic acid and alanine increased with the addition of mackerel. Sensory tests have shown the addition of mackerel did not reduce consumer acceptability towards the new fish cakes.Novelty and scientific contributionThe research demonstrated that Atlantic mackerel can be successfully used for partial replacement of white fish species in fish cake formulations to produce healthy and tasty ready-to-cook products and increase the consumption of small pelagic fish in Europe.

Summary

Introduction

Consumer awareness of health benefits associated with seafood consumption has increased the demand for fish products over the last decades [1]. The consumption of pelagic fish species is much lower than the consumption of other fish species such as salmon or cod, the total catch of pelagic fish has increased gradually during the last years in the EU and Norway [5]. This situation can partially be explained by a lack of diversity of processed pelagic fish products [8], and lack of promotion towards young consumers. Ready-to-eat/ready-to-cook fish products, i.e. canned fish, fish cakes rich in omega-3 fatty acids, vitamins and natural antioxidants could be an option for a healthy diet
