GMO HRANA
ŠTA JE GMO?
 GMO hrana je proizvedena od organizama koji su bili podvrgnuti
posebnim izmenama unutar njihove DNK
 Genetski modifikovan organizam je organizam čija je genetska struktura
izmenjena ugradnjom gena druge biljne, životinjske ili bakterijske vrste, s
ciljem kreiranja željenog svojstva
GM OBUHVATA
TEHNOLOGIJE KOJE
MODIFIKUJU
GENETSKI
MATERIJAL:
ŽIVOTINJA BILJAKA BAKTERIJA
Kad je počela proizvodnja GMO hrane?
 Komercijalna prodaja genetskih modifikovanih biljaka počela je 1994. godine
 Paradajz Flavr Savr
 Dejstvo enzima koji katališu dezintegraciju ćelijskog zida
Tehnologije koje se koriste u GM biljnih
sirovina su orijentisane ka:
 Poboljšanju ukusa,
 Smanjenju vremena sazrevanja,
 Povećanju sadržaja nutrijenata,
 Smanjenu upotrebe pesticida,
 Veća otpornost na štetočine i bolesti.
 Tehnologija rekombinantne DNK kod životinja
 Uticaj na životnu sredinu
Koja GM hrana se uzgaja?
 Ukupno je poznato 16 genetski modifikovanih kultura
 To su kukuruz, soja, pamuk, uljana repica, paradajz, krompir, šećerna repa, riža,
pšenica, karanfil, bundeva, duvan, cikorija, lan, dinja i papaja
 Na gotovo svim površinama su uzgajane pretežito četiri poljoprivredne kulture, i
to soja (čak 60% svih površina GM hrane), kukuruz, pamuk i uljana repica
Zašto se proizvodi GM hrana?
 GM hrana ima svoje prednosti u odnosu na organsku hranu
 Pre svega to su niža cena, duži vek trajanja proizvoda ili veća nutritivna vrednost
 Osnovni razlog zbog kojeg se GM hrana počela proizvoditi bila je veća otpornost
od štetočina i bolesti biljaka (smanjuje upotrebu pesticida)
Koje su opasnosti po zdravlje od strane
GM hrane?
 Alergijske reakcije
 Prenos gena
 Mutacija gastrointestinalnih bakterija
