DETERMINATION OF THE CELLULOSE- AND LIPID-CONTAINING COMPONENTS INFLUENCE ON THE EXTRUDATE TECHNOLOGICAL INDICATORS

Abstract

The effect of cellulose- and lip-id-containing components on the tech-nological parameters of the extrud-ed mixture based on protein- and starch-containing raw materials on the technological parameters of the extru-date was studied. The use of compo-nents that modify such technological indicators of the extruded mixture as water resistance and swelling is sub-stantiated. It is proposed to use sun-flower husks and sunflower phosphati-de concentrate as modifying additives to the mixture for extrusion. A ratio-nal ratio of the specified components in the extrudate was established to obtain indicators of water resistance in the range of 220...300 min and swell-ing in the range of 100...120 %. This is an important aspect of expanding the range of extruded products from the waste of oil and fat industries and obtaining high-quality competitive products.The object of the study is the depen-dence of water resistance and swelling of the extruded mixture on the content of modifying additives. Their ratio-nal ratio in the extrudate is: sunflower husk – 6.0 %; sunflower phosphatide concentrate – 5.0 %. The manufactured extrudate sample corresponds to com-mercial fish feed in terms of chemical composition and technological param-eters, and also has a 4 times lower cost. A feature of the obtained results is the possibility of regulating the water resistance, swelling and poros-ity of the extrudate based on protein- and starch-containing raw materials, depending on the ratio of cellulose- and lipid-containing modifying additives. This allows to change the technologi-cal parameters of the finished product depending on the chemical composi-tion of the mixture of raw components according to the requirements of the consumer. The results of the conduct-ed research prove that cellulose- and lipid-containing secondary products of production can be successfully trans-formed into new competitive products
