Karakterizacija kvaliteta mesa i iznutrica svinja čistih rasa odgajanih u Vojvodini / Characterisation of meat and offal quality frompurebred pigs reared in Vojvodina

<p>U ovoj doktorskoj disertaciji urađena je karakterizacija senzornog (boja i mramoriranost), tehnolo&scaron;kog (vrednost pH, boja, sposobnost vezivanja vode), nutritivnog (sadržaj vlage, proteina, ukupne masti, ukupnog pepela, P, K, Na, Mg, Ca, Zn, Fe, Cu, Mn) i toksikolo&scaron;kog (Cd) kvaliteta mesa (<em>M. semimembranosus</em> i <em>M. longissimus dorsi</em>) i iznutrica (jetra i bubreg) pet plemenitih čistih rasa (Velika<br />Bela, Landras, Durok, Hemp&scaron;ir i Pietren) svinja koje su odgajane u komercijalnom tovu i mesa (<em>M. semimembranosus</em>, <em>M. longissimus dorsi</em>, <em>M. psoas major</em> i <em>M. triceps brachii</em>) i iznutrica (jezik, srce, pluća, jetra, slezina, bubreg, mozak i kičmena moždina) jedne primitivne autohtone čiste rase (Mangulica, odnosno soj Lasasta Mangulica) svinja koje su odgajane u tradicionalnom slobodnom ispustu, a koje se u Srbiji, odnosno u Vojvodini, dominantno koriste za proizvodnju mesa.<br />Generalno, može se zaključiti da kod mesa svinja plemenitih rasa, od svih ispitanih parametara kvaliteta, rasa svinja značajno utiče samo na inicijalnu vrednost pH i to kod <em>M. semimembranosus</em>, dok mi&scaron;ić utiče na boju (senzorno ocenjenu i vrednosti L*, a* i b*) i sposobnost vezivanja vode (vrednost M/RZ i vrednost M/T). Kod mesa svinja Lasaste Mangulice mi&scaron;ić značajno utiče na krajnju vrednost pH, boju (senzorno ocenjenu, vrednosti L* i a*), mramoriranost, sposobnost vezivanja vode (vrednost T), sadržaj vlage, ukupne masti, P, Na, Mg, Ca, Zn, Fe, Cu i Mn. Sa druge strane, osim u slučaju sadržaja Ca u jetri i bubregu svinja plemenitih rasa, vrsta tkiva iznutrica značajno utiče na sva ispitana svojstva kvaliteta iznutrica svinja plemenitih rasa i svinja Lasaste Mangulice.<br />Utvrđene pojedinačne vrednosti svih ispitanih faktora kvaliteta mesa i iznutrica ukazuju na veoma veliko variranje kvaliteta mesa i iznutrica, &scaron;to ukazuje na potrebu povezivanja tehnologije odgajivanja svinja i tehnologije proizvodnje mesa optimizacijom svih faktora proizvodnje, koji sami po sebi nisu karakteristike kvaliteta mesa, ali koji značajno utiču na njegov kvalitet.</p> / <p>In this PhD thesis, characterization of sensory (color<br />and marbling), technological (pH, color, water holding<br />capacity), nutritional (content of moisture, protein, total<br />fat, total ash, P, K, Na, Mg, Ca, Zn, Fe, Cu, Mn) and<br />toxicological (content of Cd) quality of meat (M.<br />semimembranosus and M. longissimus dorsi) and offal<br />(liver and kidney) from five modern purebred pigs<br />(Large White, Landras, Durok, Hemp&scaron;ir and Pietren)<br />reared in commercial condition was done. Also,<br />characterization of meat (M. semimembranosus, M.<br />longissimus dorsi, M. psoas major and M. triceps<br />brachii) and offal (tongue, heart, lungs liver, spleen,<br />kidney, brain, spinal cord) quality from free-range reared<br />indigenous purebred pigs of Swallow-belly Mangulica,<br />was done. These modern and indigenous purebreds are<br />predominantly used for meat production in Serbia, and in<br />Vojvodina.<br />Generally, it can be concluded that in modern<br />purebred pigs, only the initial pH value in M.<br />semimembranosus, of all the investigated quality<br />parameters, was significantly affected by bred, whily the<br />muscle significantly affected the color (sensory<br />evaluated and the value of L*, a* and b*) and water<br />holding capacity (the value of M/RZ, the value of M/T).<br />In Swallow-belly Mangulica pigs type of the muscle<br />significantly affected the ultimate pH, color (sensoryrated,<br />the value of L* a*), marbling, water holding<br />capacity (value of T), content of moisture, total fat, P,<br />Na, Mg, Ca, Zn, Fe, Cu and Mn. On the other hand,<br />except in the case of the Ca content in the liver and<br />kidney of modern purebred pigs, type of the tissue<br />significantly affected all of the investigated quality<br />properties of offal from modern purebred pigs and<br />Swallow-belly Mangulica pigs.<br />Determined individual values of all investigated<br />factors of meat and offal quality indicated a very large<br />variation of meat and offal quality, what indicates the<br />need to combine pig breding technology and meat<br />technology by optimization of all factors of production,<br />which in themselves are not the characteristics of meat<br />quality, but significantly affect on it&rsquo;s quality.</p>
