Potential use of fish oil to partially replace pork back fat in Czech meat product "Špekáček"
Original language description
Traditional Czech sausage "Špekáček" was prepared with pharmaceutical cod liver oil as a replacement for pork back fat. Pharmaceutical cod liver oil acts as a source of EPA and DHA fatty acids. Fish oil was incorporated directly to meat emulsion in cutter in amount 1.5% and 3.0%. Basic chemical analysis was performed (the content of protein, fat, salt and dry matter). Fatty acid profile was also determined. The amount of EPA and DHA was gradually increased with the addition of fish oil (p < 0.05). Instrumental measurement of texture and colour was executed. Sausages with added oil in amount 3.0% had higher L* value than control (p < 0.05). Microbiological analysis was performed 21 days after processing, the microbial population was low and sausages were microbiologically acceptable. Hedonic test was used for sensory analysis. Heated sausages with fish oil (1.5%, 3.0%) were evaluated worse in taste against control (p < 0.05). Evaluators have responded positively to unheated sausages with fish oil (3.0%). This shows that meat products that are consumed unheated (bologna salami, fermented salami) have a greater potential in fat replacement with fish oil.
