RESEARCH ON REDUCING THE LENGTH OF MATURATION IN USING ELECTROSTIMULATION OF BEEF

Abstract

From technological point of view in the food industry has been obtained meat maturation using different methods: storage under controlled conditions, the use of enzymes or mechanical equipment tenderization musculature. Was also reported that electrical stimulation of carcasses immediately after slaughter procedure can increase the degree of maturation of the meat. Meat and meat products are subjected to reduce during chilling and freezing temperatures principal for reasons of conservation or meat packing. Particular attention must be paid to temperature control, especially before rigor mortis, knowing that too rapid cooling could lead to a cold shortening or thaw rigor during the thaw. During application of the electrostimulation process, occur physical and biochemical changes, meaning that this one has some effect on the technological properties of meat. It has obtained a reduction of maturation of beef with the electrostimulation of half-carcasses of cattle, verified by the increase of non-protein nitrogen in meat. The same time it has been considerably improved the texture and firmness of the muscles, which allows the use of beef in fast food products (ready to cook). Researches have revealed the conclusion that the use of the portable device for electrostimulation, in the described conditions, has induced positive transformations improving meat quality of adult beef.
