Abstract

Mikotoksini su sekundarni metaboliti toksikotvornih plijesni koji izazivaju niz štetnih učinaka na zdravlje ljudi i životinja. Osim što uzrokuju bolesti u ljudi i životinja, kontaminacije mikotoksinima uzrokuju velike ekonomske gubitke. Zbog učestalih kontaminacija i termostabilnosti mikotoksina potrebno je stalno kontrolirati koncentraciju mikotoksina u hrani i po potrebi smanjiti razinu mikotoksina. Metode za uklanjanje mikotoksina se dijele na kemijske, fizikalne i biološke. Biološke metode se smatraju sigurnijima i ekološki prihvatljivijima, a uključuju primjenu mikroorganizama te adsorbensa organskog ili anorganskog porijekla. U ovom radu se ispitala sposobnost vezanja aflatoksina B1 na biosorbense (koštice masline, ljuske jajeta i kokosovo brašno). Sve tri vrste adsorbensa su pokazale vrlo dobro vezanje AFB1 već na samom početku eksperimenta kao i mogućnost upotrebe sličnih adsorbensa u dekontaminaciji mikotoksina.

Abstract (english)

Mycotoxins are secondary metabolites of toxic molds that cause a number of adverse effects on human and animal health. In addition to causing disease in humans and animals, mycotoxin contamination causes great economic losses. Due to frequent contamination and thermostability of mycotoxins, it is necessary to constantly monitor the concentration of mycotoxins in food and, if necessary, reduce the level of mycotoxins. Methods for removing mycotoxins are divided into chemical, physical and biological. Biological methods are considered safer and more environmentally friendly and include the use of microorganisms, organic and anorganic adsorbents. In this research, the ability of aflatoxin B1 to bind to biosorbents (olive pits, egg shells and coconut flour) was examined. All three types of adsorbents showed effective binding of AFB1 at the very beginning of the experiment as well as the possibility of using similar adsorbents in mycotoxin decontamination.
