The influence of pig fodder composition on quality of dried pork neck | Vpliv sestave krme in spola prašičev na kakovost sušenih vratin

إنجليزي. The aim of the article is to show the influence of diet composition and sex on sensory and instrumental quality of dried pork neck. For the research we used 12 hogs and 12 sows. They were separated into 4 groups regarding different food mixture (flaxseed, rapeseed, rapeseed+vit.E and control mixture). All 24 samples of dried neck were analyzed on fat content. Sensory analysis of dried necks and instrumental measurement of colour (CIE -L, -a, -b) and texture (Kramer shear cell) were performed. The results showed that different fodder composition had no influence on fattiness of the product, while sex had a significant influence. Aftertaste was perceived by feeding with addition of flaxseed and rapeseed. Added vitamin E decreased sensory characteristics (smell, aroma, texture) and gave lighter colour. The firmer texture was shown by feeding with rapeseed. Neck from hogs had darker colour and firmer texture than neck from sows.

السلوفينية. Namen članka je predstaviti vpliv spremenjene sestave krme in spola praöičev na senzorične in instrumentalne lastnosti suöenih vratin. V raziskavo je bilo vključenih 12 kastratov in 12 svinjk. Razdelili smo jih v ötiri skupine glede na različne dodatke h krmi (laneno seme, ogröčično seme, ogröčično seme+vit. E in kontrolna meöanica). V vseh 24 vzorcih suöenih vratin smo določili skupno količino maöčob, jih senzorično ocenili ter instrumentalno določili barvo (CIE -L, -a, -b) in teksturo (striûna trdnost ñ Kramerjeva celica). Rezultati so pokazali, da različni dodatki h krmi ne vplivajo na skupno vsebnost maöčob, medtem ko ima spol statistično značilen vpliv. Priokusi se pojavijo pri skupinah, krmljenih z dodatkom lanu in ogröčice. Dodatek vitamina E poslaböa senzorične lastnosti (vonj, aroma, tekstura) in da mesu najsvetlejöo barvo. Tekstura je najčvrstejöa pri krmljenju z dodatkom ogröčice. Suöena vratina kastratov je temnejöe barve in čvrstejöe teksture kot vratina svinjk.
