Abstract | Carotenoids are known for their lower environmental pollution, lower costs, shorter extraction time compared to regular extraction methods and higher extraction efficiency. Ultrasound has significant advantages in the extraction of a great number of biologically active compounds including carotenoids. Benefits of using ultrasound for extraction of various compounds are numerous and include effective mixing and micro-mixing, more efficient energy transfer, reduced thermal and concentration gradients, reduced temperature. The aim of this work was to investigate the influence of two-frequency ultrasound main parameters such as ultrasonic intensity, sonication time, and temperature. Application of two-frequency ultrasound (simultaneous influence of ultrasound with frequency of 20-46 kHz, intensity of 1.5-2.5 W/[cm.sup.2] and frequency of 1.0-2.0 MHz, intensity of 2.0- -3.0 W/[cm.sup.2]) raises the percentage of [beta]-carotene extraction from biomass of the fungus Blakeslea trispora from 90-92% up to 98-99% in comparison with one frequency ultrasound. The recommended oil temperature for the extraction process is 35[degrees]C, because lower temperature leads to reduction of percentage of [beta]-carotene extraction, and higher temperature promotes unjustified increase of expenditure of energy. Keywords: ultrasound, [beta]-carotene, Blakeslea trispora, two-frequency ultrasound. IZVOD (Naucni rad) Karotenoidi su vrlo dobro poznati po svom uticaju na zivotnu sredinu u smislu niske toksicnosti, jeftini su, potrebno je krace vreme za njihovu ekstrakciju u poredenju sa standardnim metodama ekstakcije odredenih komponenti i sto je vrlo bitno efikasnost ekstrakcije je visoka. Ultrazvuk ima znacajne prednosti kada se radi o ektrakciji velikog broja bioloski aktivnih komponenti ukljucujuci i karotenoide. Prednosti ultrazvucne ekstrakcije odredenih komponenti su mnogobrojne i ukljucuju efikasno mesanje, efikasniju razmenu energije, redukovani termicki i koncentracioni gradijent i niza temperatura ekstrakcije. Cilj ovog rada je ispitivanje uticaja glavnih parametara ultrazvucne ekstrakcije izvrsene istovremenim tretiranjem niskom i visokom frekvencijom kao sto su ultrazvucni intenzitet, vreme trajanja tretiranja i temperatura. Primena ultrazvuka sa niskom i visokom frekvencijom (simultano tretiranje ultrazvukom frekvencije od 20-46 kHz, intenziteta od 1,5-2,5 W/[cm.sup.2] i frekvencije od 1,0-2,0 MHz, intenziteta od 2,0-3,0 W/[cm.sup.2]) podize procenat ekstakcije [beta]-karotena iz biomase gljive Blakeslea trispora sa 90-92 na 98-99% u poredenju sa tretiranjem ultrazvukom sa jednom frekvencijom. Preporucena temperatura ulja u procesu ekstrakcije je 35[degrees]C, zbog toga sto niza temperature dovodi do redukcije procenta ekstrakcije [beta]-karotena a visa temperatura vodi ka neopravdanom povecanju troskova energije.
