ABSTRACT
Seafood products represent an important source of proteins and minerals as well as polyunsaturated fatty acids. However, its consumption in Brazil is very low in comparison to other kinds of meat. This may due to lack of skill in its preparation, making immensurable the importance of the search for new ways to market it, such as ready-made or semi-ready to serve products. The trawl fishery method often accidentally captures a variety of species, composed basically of low commercial value and size. Such catches are called “second-hand catch”. With this in mind, this paper has as its main objective de development of two products: fish meatball and kibe, using what is considered accidental catches in the trawl fishery industry done on Rio de Janeiro's offshore as the raw material. The taxonomic identification of the species resulted in the species, Red porgy (Pagrus pagrus), Argentine croaker (Umbrina sp.), Atlantic bigeye (Priacanthus arenatus), Black cusk-eel (Conger sp.), Cusk-eel (Genypterus brasiliensis) and Blackfin goosefish (Lophius gastrophysus). The dry material of the raw product was 31.20±1.30%, in the raw meatball and kibbeh the values was 37.90±1.10 and 32.10±1.10, respectively, in the baked product the results was 33.40±1.20 and 34.20±1.00 (kibbeh and meatball). The ash content in the pulp was 1.5%, for the raw kibbeh and meatball, the amounts of ash were 2.55±0.05 and 1.47±0.05, respectively. For baked goods results were 1.87±0.05 for the kibbeh and 1.92±0.05 for the meatball. The measured lipid levels in the pulp was 4.80±0.30%. In respect, raw kibbeh and meatball, the percentage of lipids were 4.20±0.80 and 4.20±0.60, respectively. For baked goods was 4.50±0.60 for the kibbeh and 4.40±0.60 for the meatball. The protein level presented in the raw material was 15.60±1.04%, to the raw kibbeh and meatball was 17.80±2.16 and 14.90±2.12 and for the baked goods 15.10±2.10 both. Soluble nitrogen compounds shows values of 285mg/100g in the raw material, in the kibbeh NNP 291mg/100g and the meatball NNP 294mg/100g. The results of the total count of psychotropic remained below 7.0 log CFU/g, for standard count of aerobic microorganism plates. Fecal coliform bacteria, Salmonella, and Staphylococcus aureus were not present. The levels of histamine and sulfur basic compounds (H2S) were not detected in the samples.
