AB  - Mechanical extraction is one of the oldest oil extraction methods. The advantages of mechanical extraction of oil 
in relation to chemical are better oil quality and greater possibility of using pressing cake compared to meal 
containing traces of solvent. Critical parameters in the cold pressed oil production are the raw (pressing) material 
characteristics (type, hull content, oil and moisture content), feeding the press with pressing material, 
temperature, expeller screws speed rotation, nozzles diameter, pre-treatment of pressing material. Since 
sunflower oil belongs to the group of the most represented edible vegetable oils in the world, as in Serbia, this 
paper aims to investigate the newest sunflower hybrids. The aim of this study was to examine the influence of 
sunflower seed characteristics on pressing capacity, oil yield and pressing parameters using global sensitivity 
analysis. The mentioned analysis was preceded by the application of artificial neural networks, which was used 
to predict the capacity, oil yield and pressing parameters based on the obtained characteristics of the seed. It was 
determined that the oil and seed yield had the greatest positive impact on the seeds oil content (24.43 and 
26.85%, respectively), as well as the mass of pressing materials (10.04 and 11.64%). The biggest negative 
impact on these two output parameters had the cake oil content (-16.65 and -14.31%). The obtained result 
indicates that the seeds mass has a decisive influence on the seeds flow through the press, and confectionary 
sunflower hybrids with a significantly higher 1000 seeds mass, compared to oily hybrids, had a significantly 
lower seed flow. Also, the global sensitivity analysis confirmed that sunflower seeds with higher dimensions and 
seeds mass reached higher oil temperature during pressing.

AB  - U svetu, prema podacima Organizacije za hranu i poljoprivredu (Food and Agriculture Organization, FAO) i Departmana za poljoprivredu Sjedinjenih Američkih Država (United States Department of Agriculture, USDA) proizvodnja semena suncokreta raste.

Istraživanjem u ovom radu pokazano je da je proizvodnja ulja postupkom hladnog presovanja moguća i od konzumnih hibrida suncokreta, ne samo od uljanih, međutim razlike u iskorišćenju i kapacitetu tj. količini dobijenog ulja su značajne. Iskorišćenje ulja i semena bili su 2,12 i 2,17 puta veći kod uljanih u odnosu na konzumne hibride suncokreta, dok za 1 h kroz presu prođe 1,84 puta više semena i dobije se 3,89 puta više ulja, kod uljanih u odnosu na konzumne hibride suncokreta.
AB  - According to the Food and Agriculture Organization (FAO) and the United States Department of Agriculture (USDA), world sunflower seed production is increasing. The needs for the production of oil and high-quality proteins are growing in the world, which is the reason for sunflower hybrids divergence in oily and confectionary (non-oily, protein) hybrids, in order to meet the mentioned needs. Research in the paper has shown that the production of oil by cold pressing is possible from confectionary sunflower hybrids, not only from oily, but the differences in the oil yield and amount of obtained oil are significant. Oil and seed yield were 2.12 and 2.17 times higher for oily compared to confectionary sunflower hybrids, while 1.84 times more seed and 3.89 times more oil of oily hybrids passed through the press in 1 hour compared to confectionary sunflower hybrids.
