COMPARISON OF CONSUMABLE EGGS QUALITY OF DIFFERENT PRODUCERS

Cilj ovog rada bio je usporediti kvalitetu konzumnih jaja klase L tri proizvođača, koja se nalaze u trgovačkim centrima na području grada Osijeka. Od pokazatelja kvalitete jaja u radu su uspoređene vrijednosti mase jaja i njegovih osnovnih dijelova, te su uspoređeni pokazatelji vanjske i unutarnje kvalitete jaja. Iako su jaja pripadala klasi L pronađene su razlike između proizvođača. Najveća masa jaja zabilježena je kod proizvođača B (66,14 g) dok je masa jaja proizvođača A i B bila ujednačena (65,05 g i 65,03 g; P=0,158). U masi bjelanjka nije bilo značajnih razlika između jaja različitih proizvođača (P=0,152). U vrijednostima mase žumanjka statistički značajno teže žumanjke imala su jaja podrijetlom od proizvođača B u usporedbi s proizvođačima A i C (18,19 g : 17,12g i 16,90 g ; P0,05). Analiza usporedbe kvalitete jaja različitih proizvođača pokazuje da konzumna jaja na tržištu grada Osijeka zadovoljavaju kvalitetom i odgovaraju propisima Pravilnika o kakvoći jaja u Hrvatskoj.The aim of this study was to compare consumable eggs quality class L of three producers, located in shopping malls in the city of Osijek. Indicators of egg quality compared in this work are values of the mass of eggs and its basic components and external and internal quality of eggs of three producers. Although the eggs were class L there were differences among producers. The highest weight of eggs was recorded for producer B (66.14g), while the egg mass for producers A and B were equal (65.05g and 65.03g, respectively, P=0.158). In the egg white weight there was no significant difference between eggs of different producers (P=0.152). By comparing yolk mass values, significantly heavier egg yolks originated from producer B in comparison with producer A and C (18.19g: 17.12g and 16.90g, respectively, P0.05). Analysis of the egg quality of different producers shows that consumable eggs in our market are satisfactory in with quality and correspond to the Regulations on the quality of eggs in Croatia
