At the Food Production Department of Murmansk State Technical University (MSTU) was developed a technology of production of smoked fish products with the use of air-flue mixture, produced in an infrared smoke generator under conditions of low-temperature pyrolysis of wood chips with an initial moisture content of 40 to 60% and a bulk density of from 104 to 154 kg/m3. A method of producing smoke and its hardware design enabled to securely control the temperature of the smoke receiving smoking environment, which guarantees a minimum content of threat to human health of polycyclic aromatic hydrocarbons (РАНs). The developed technology involves short cycle smoked salted semi – fish fillets and allows to obtain finished products with excellent organoleptic properties. The content of РАНs in finished products less than 0.0002 microgram/kg, which is significantly below the maximum permissible concentrations (MPC) according to the requirements of SаnРiN 2.3.2.1078 (less than 0.001 mg/kg product) and according to the requirements of TR CU 021/2011 (0.005 mg/kg product). This technology successfully implemented in production at fish processing plants in Murmansk region. However, marketing research has shown that the market for smoked fish in the Murmansk region is characterized by a narrow range, which affects consumer demand and reduces the competitiveness of the regional enterprises-manufacturers of smoked products. To solve this problem it is offered to expand the range of smoked fish products due to use of non-traditional Smoking techniques raw materials – fillet of cod fish (saithe, haddock, cod). To improve consumer properties of products, in particular, to improve the indicator of “consistency: and "juiciness" of the proposed use on the stage of the salting of prefabricated enzyme preparation from hepatopancreas of snow crab (Chionoecetes opilio), added to brine with density of 1.18 to 1.2 g/сm3 at a dosage of 0.04%, the curing time of the mix in the brine for 15 minutes. When optimizing technological regimes of ...
