Abstract

Funkcionalna hrana je hrana čijom se konzumacijom ostvaruje povoljan učinak na ljudsko zdravlje. Dizajnirana jaja mogu se svrstati u kategoriju funkcionalne hrane, a njihova je proizvodnja omogućena modificiranjem ili dizajniranjem smjese nesilica pri čemu se na neke nutrijente može utjecati u većoj mjeri. Hranidba kokoši nesilica bogata omega-3 masnim kiselinama rezultira povećanjem sadržaja omega-3 masnih kiselina u jajetu, poboljšava se omjer ω-3:ω-6. Kokoši lako apsorbiraju i prenose omega-3 masne kiseline iz hrane te se one akumuliraju u žumanjku, pri čemu se najefikasnijim pokazalo dodavanje ribljeg ulja u prehranu. Selen, vitamin E i lutein sprječavaju oksidaciju masnih kiselina te osiguravaju stabilniji i dugotrajniji proizvod, a istovremeno se ostvaruje povoljan utjecaj na zdravlje. Za razliku od konvencionalnih jaja, dizajnirana nam jaja omogućuju veći unos nutrijenata koji pozitivno djeluju na ljudsko zdravlje i pomažu u prevenciji određenih bolesti.

Abstract (english)

Functional food is food whose consumption has a beneficial effect on human health. Designed eggs can be categorized as functional food and their production is made possible by modifying or designing a feeding mixture where some nutrients can be modified more than others. A diet of laying hens rich in omega-3 fatty acids results in an increase in the content of omega-3 fatty acids in the egg, improving the ratio of ω-3: ω-6. Chickens easily absorb and transfer omega-3 fatty acids from food and accumulate it in egg yolks, with fish oil being most effective in the diet. Selenium, vitamin E and lutein prevent the oxidation of fatty acids and provide a more stable and long-lasting product, while having a beneficial effect on health. Unlike conventional eggs, designed eggs allow us to increase our intake of nutrients that have a positive effect on human health and help prevent certain diseases.
