Abstract
Investigations were carried out on four muscles (M. longissimus dorsi, M. semimembranosus, M. semitendinosus, M. biceps femoris) taken from five young cattle (crosses Domestic Spotted x Limousine) of average body mass prior to slaughtering of 587 kg. On all muscles, 24 h after slaughtering, sensory evaluation was carried out and the following parameters determined: pH value, colour, water binding ability, cooking loss and tenderness (initial values). The remaining part of each muscle was divided into 6 parts, 3 were packaged in plastic foil (control samples), and other 3 were soaked in solution containing 0,4% CaCl2 and 0,4% NaCl and packaged in plastic foil. Pieces of meat prepared in this way were left on temperature of + 40C 7, 14 and 21 days to mature. After this period, all mentioned analyses were carried out on meat samples. It was established that pH value during maturation increased, that meat packaged in plastic foil after 14 days of maturation becomes unusable, whereas the in...crease of pH values of meat whose maturation occurred in solution CaCl2 and NaCl was slower and therefore meat was still usable after 21 days. Color of meat in control samples was slightly lighter compared to initial condition, whereas the color of meat whose maturation occurred in solutions of salt was statistically considerably lighter (P (lt) 0,05 after 7 days, a P (lt) 0,001 after 14 and 21 days). Water binding ability in control samples was slightly better (P>0,05) after 7 days and after 14 days it was statistically significantly better (P (lt) 0,05) compared to initial state, whereas in meat whose maturation occurred in salt solution this ability was at initial level even after 21 days. Cooking loss in control samples was lower compared to initial values whereas in meat soaked in salt solution cooking loss was higher. Meat tenderness in control samples was statistically considerably better after 14 days of maturation (when meat was not fit for use) and in meat soaked in salt solution it was statistically highly significantly better after 14 and 21 days. According to sensory evaluation, control samples of meat, after 14 days of maturation are not fit for use, whereas meat whose maturation occurred in solution of CaCl2 and NaCl even after 21 days is acceptable from the sensory aspect.

Ispitivanja su obavljena na četiri mišića (M. longissimus dorsi, M. semimembranosus, M. semitendinosus, M. biceps femoris) uzetih od pet junadi (melezi domaće šareno goveče x limuzin), prosečne mase pred klanje 587 kg. Na svim mišićima 24 sata posle klanja obavljena je senzorna ocena i određeni su: pH vrednost, boja, sposobnost vezivanja dodate vode, kalo kuvanja i mekoća (početne vrednosti). Ostatak svakog mišića podeljen je na 6 delova od kojih su po 3 upakovani u plastičnu foliju (kontrolni uzorci), a ostala 3 dela su potopljena u rastvor koji sadrži 0,4% CaCl2 i 0,4% NaCl i upakovani u plastičnu foliju. Ovako pripremljeni komadi mesa ostavljeni su pri temperaturi od + 40C 7, 14 i 21 dan na zrenju. Posle isteka zadatog vremena urađena su na komadima od svih mišića navedena ispitivanja.Utvrđeno je da se pH vrednost tokom zrenja povećava i da u mesu koje je upakovano u plastičnu foliju posle 14 dana zrenja dospeva u oblast kad je meso neupotrebljivo, dok je povećanje pH vrednosti kod ...mesa čije se zrenje odvijalo u rastvoru CaCl2 i NaCl sporije tako da je meso i posle 21 dan upotrebljivo. Boja mesa kod kontrolnih uzoraka bila je neznatno svetlija u odnosu na početno stanje, dok je boja mesa čije se zrenje odvijalo u rastvoru soli bila statistički značajno svetlija (P (lt) 0,05 nakon 7 dana, a P (lt) 0,001 nakon 14 i 21 dan). Sposobnost vezivanja vode kod kontrolnih uzoraka bila je neznatno (P>0,05) bolja nakon 7 dana dok je nakon 14 dana bila statistički značajno bolja (P (lt) 0,05) u poređenju sa početnim stanjem, dok je kod mesa čije se zrenje odvijalo u rastvoru soli i posle 21 dan bila na nivou početnog stanja. Kalo kuvanja kod kontrolnih uzoraka bio je manji u poređenju sa vrednostima na početku ogleda dok je kod mesa potopljenog u rastvor soli bio veći. Mekoća mesa kod kontrolnih uzoraka bila je statistički značajno bolja nakon 14 dana zrenja (kad je meso bilo neupotrebljivo) dok je kod mesa potopljenog u rastvor soli bila statistički visoko značajno bolja posle 14 i 21 dan. Prema senzornoj oceni kontrolni uzorci mesa nakon 14 dana zrenja postaju neupotrebljivi, dok je meso čije se zrenje odvijalo u rastvoru CaCl2 i NaCl i nakon 21 dan zrenja senzorno veoma prihvatljivo.
