Extrusion process technology for feed and food used in animal nutrition

Abstract

Deficit of food for population that grows every year, significantly makes the food production a very important problem the world and in Serbia. The solution to increase the feed and food production is in the usage of new technologies, technologies in biotechnology, actually in bioindustry. One of the main features of contemporary agriculture is production of feed of high nutritive value and microbiologically safe feed in sufficient quantities. The most important feedstuffs that are used in animal nutrition like cereals and other grain - soybean, rapeseed, corn, barley and sorghum, beside nutritive substances contain certain antinutritive substances, that represent limiting factor of their usage. Many antinutritive substances can be eliminated or significantly reduced with the usage of adequate heat treatments. The aim of this study was to collect, display and interpret the results, achievements and latest world science and technology trends trough application of contemporary technical and technological processes of feed processing. With the application of the latest heat treatment, such as extrusion, it comes to destruction of antinutritive substances and improvement of nutritive, hygienic, physical-chemical and other feed properties. The usage of processing technology such as extrusion is certainly one of the most important alternatives for feed and food production which by its high nutritive values can fulfill high demands of modern nutrition.
