AB  - Acrylamide is toxic and probably carcinogenic compound, made as a result of high-temperature thermal treatment of carbohydrate-rich foodstuffs. In this article a method is improved for the extraction and quantitation of acrylamide in foods produced based on corn flour that are represented in our traditional diet. Acrylamide extraction was carried out using reduced volume of saturated solution of bromine water and the GC–MS method for the quantification was shown. Quantification of acrylamide was preceded by: sample homogenization, acrylamide extraction using water, extract purification using solid phase extraction, bromination, using a reduced volume of bromine water solution, dehydrobromination with sodium thiosulfate and transformation of dibromopropenamide in 2,3,2-bromopropenamide using triethylamine. Regression and correlation analysis were applied for the probability level of 0.05. Calibration is performed in the concentration range 5–80 ug/kg with a detection limit 6.86 mg/kg and the limits of quantification 10.78 ug/kg and the coefficient of determination R2 > 0.999. Calibration curve was obtained: y = 0.069x + 0.038. Recovery values were an average from 97 to 110%. Proposed GC–MS method is simple, precise and reliable for the determination of acrylamide in the samples of thermal treated foods. Our results show that the tested foods quantify the presence of acrylamide in concentrations of 18 to 77 mg/kg acrylamide depending on whether the food was prepared by cooking or baking.

AB  - Substances with hormonal activity in food can be of natural origin like hormones in milk and milk product and phytoestrogens, or residues of hormones used as growth promoters or drugs for farm animals. It is estimated that 60-80% of the total intake of hormones with food is from milk and milk products. During pregnancy levels of estrogens and progesterone are significantly increasing and becoming the highest before parturition. Results of the number of studies indicate that dietary intake of estrogens from milk and milk product can be the risk factor for hormone-dependent carcinomas, or same reproductive disorders. Phytoestrogens could have some benefitial effects on hormonal balance especially for women in menopause but additional investigations are needed for their safe use and appropriate dosing in food supplements. In some countries (USA, Canada, Australia) controlled use of hormones as growth promoters is legal, while in EU and Serbia the use of hormones in food production is strictly prohibited. To prevent the illegal use of hormones it is important to establish the national program for monitoring of residues of hormones in food.
AB  - Hormoni u namirnicama mogu da budu prirodnog porekla kao što su hormoni u mleku i fitoestrogeni, ili rezidue hormonskih stimulatora rasta i lekova korišćenih u terapiji životinja. Procenjuje se da 60-80% ukupnog unosa hormona hranom potiče iz mleka i mlečnih proizvoda. U toku graviditeta nivo estrogena i progesterona se značajno povećava i maksimum postiže pred teljenje. Rezultati velikog broja studija ukazuju da dijetarni unos estrogena iz mleka i mlečnih proizvoda može da bude faktor rizika za hormon-zavisne karcinome, ali i za smanjenje reproduktivne spospobnosti, ginekomastiju kod dečaka i prevremeni pubertet kod devojčica. Smatra se da bi supstance sa hormonskom aktivnošću iz nekih namirnica biljnog porekla (fitoestrogeni) mogle da imaju pozitivan efekat u uspostavljanju hormonske ravnoteže kod žena u menopauzi ali su potrebna dodatna ispitivanja za njihovu bezbednu upotrebu i adekvatno doziranje u dijetetskim suplementima. U nekim zemljama (SAD, Kanada, Australija) dozvoljena je kontrolisana primena hormona kao stimulatora rasta životinja, dok je u EU i Srbiji njihova upotreba strogo zabranjena. Zbog ilegalnog korišćenja hormona u proizvodnji hrane potrebno je uspostaviti nacionalni program monitoringa rezidua hormona u namirnicama.
