Projekat:
Novi koncept oplemenjivanja sorti i hibrida povrća namenjenih održivim sistemima gajenja uz primenu biotehnoloških metoda (MPNTR - 31059)

Ključne reči: cvekla; mrkva; organska; konvencionalna; sokovi; sušeni proizvod
Sažetak
Da bi se izvršila popularizacija organski proizvedenog povrća, ispitane su dve povrtarske vrste koje se najčešće gaje u organskom sistemu u Srbiji. Ovo istraživanje ima za cilj da se ispitaju razlike u sadržaju fitonutrijenata kod cvekle i mrkve poreklom iz organske i konvencionalne proizvodnje, kod svežih korenova, kod sokova pasterizovanih na različitim temperaturama (70 i 90oC) i sušenog proizvoda. Korišćena je multivarijaciona analiza (analiza glavnih komponenti) kako bi se odredile glavne komponente nosioca najveće varijabilnosti, poreklom iz obe proizvodnje na osnovu prosečnog sadržaja fitonutrijenata kod cvekle i mrkve. Ispitivani uzorci nalaze se u dva klastera, klaster za mrkvu i klaster za cveklu, s tim što se u okviru svake pojedinačne grupe mogu definisati po dve podgrupe. Podgrupe za cveklu: I - sušeni uzorci i sokovi na 90oC iz oba načina proizvodnje; i II - sveža cvekla i pasterizacija na nižim temperaturama. Podgrupe za mrkvu: I - sušeni uzorci; i II - ostali tretmani zajedno sa svežom mrkvom iz oba načina proizvodnje. U ovim ispitivanjima za mrkvu se generalno može reći da je stabilnija za preradu od cvekle, a na osnovu uzoraka koji su sa ispitivanog područja, iz dva načina proizvodnje i za fitonutrijente obuhvaćene ovim ispitivanjem.
