High-technology methods of processing fish raw materials farmed in Astrakhan region
The modern level of development of fish processing technology is analyzed. A number of high-tech processes related to deep processing of aquaculture objects (paddlefish, clary catfish and tilapia), grown in the Astrakhan region, in closed water supply installations, have been proposed for implementation. The chemical composition of fish muscle tissue has been studied. A method has been developed to reduce the microbial contamination of raw materials using a low-frequency electromagnetic field. Methods of electrophysical and gas-liquid processing of raw materials have been adapted to real production conditions. Methods for processing secondary fish resources into edible fish meal and fish oil have been tested using gas-liquid technologies. Methods for processing water and muscle tissue of fish raw materials by electromagnetic and gas-liquid methods are proposed. The chemical composition of fish pates enriched with CO2-extracts was investigated.
