Influence of ultrasound on triticale was investigated. Triticale is a cereal characterized with high yields per hectare and its ability to grow on marginal lands. It's most frequently used as animal feed supplement or in bread industry in combination with wheat flour. Nowadays, it's more widely used as a unmalted raw material in brewing industry. In this paper, samples of triticale variety Odyssey (crop 2008) were obtained from Institute of Field and Vegetable Crops Novi Sad (Serbia), from Rimski Šančevi location. Due to constant need for more efficient production in brewing technology, new treatments of raw material have emerged. With the use of ultrasound treatment, particle sizes of triticale obtained from milling process can be reduced up to 20 times which benefits to liquefaction and saccharification of starch. In this paper, influence of ultrasound on triticale starch is analyzed using 2x2.5 and 2x5 minute ultrasound treatment with temperature regimes of 50 deg C and 60 deg C for duration of 65, 85 and 125 minutes. Ultrasound treatments of triticale mash gave both positive and negative results depending on applied time of ultrasound treatment and used temperature treatment. Best results were obtained using 2x2.5 minute of ultrasound treatment with temperature treatment of 60 deg C for duration of 125 minutes which would result in better degradation of triticale flour and benefit production of final product-beer.
