Opis:
Introduction and objective. Acrylamide is a “probably human carcinogen” monomer that can form in heated starchy food as a result of a reaction between asparagine and reducing sugars via Maillard reaction. The main source of acrylamide in human diet are potato products, cereal products and coffee. Tobacco smoke may be another significant source of exposure to acrylamide. The aim of our study was to determine acrylamide content in cigarettes available on the Polish market and to estimate the exposure to acrylamide originating from tobacco smoke in smokers in Poland. Materials and methods. The material was cigarettes of the top five brands bought in Poland and tobacco from non-smoked cigarettes. Acrylamide content in cigarettes mainstream smoke was determined by LC-MS/MS. Exposure assessment was carried out using analytical data of acrylamide content in cigarettes and the mean quantity of cigarettes smoked daily by smokers in Poland, assuming body weight at 70 kg. Results. The mean content of acrylamide was 679.3 ng/cigarette (range: 455.0 – 822.5 ng/cigarette). The content of acrylamide was evidenced to correlate positively with total particulate matter (TPM) content in cigarettes. The estimated average exposure to acrylamide from tobacco smoke in adult smokers in Poland is 0.17 μg/kg b.w./day. Conclusions. Our results demonstrate that tobacco smoke is a significant source of acrylamide and total exposure to acrylamide in the population of smokers, on average, is higher by more than 50% in comparison with non-smokers. Our estimation of exposure to acrylamide from tobacco smoke is the first estimation taking into account the actual determined acrylamide content in the cigarettes available on the market.

Opis:
Introduction. Functional food plays an important role in the prevention, management and treatment of chronic diseases. One of the most interesting techniques of functional food production is extrusion-cooking. Functional foods may include such items as puffed cereals, breads and beverages that are fortified with vitamins, some nutraceuticals and herbs. Due to its pharmacological activity, chamomile flowers are the most popular components added to functional food. Objective. Quantitative analysis of polyphenolic antioxidants, as well as comparison of various methods for the extraction of phenolic compounds from corn puffed cereals, puffed cereals with an addition of chamomile (3, 5, 10 and 20%) and from Chamomillae anthodium. Materials and Methods. Two modern extraction methods – ultrasound assisted extraction (UAE) at 40 °C and 60 °C, as well as accelerated solvent extraction (ASE) at 100 °C and 120 °C were used for the isolation of polyphenols from functional food. Analysis of flavonoids and phenolic acids was carried out using reversed-phase high-performance liquid chromatography and electrospray ionization mass spectrometry (LC-ESI-MS/MS). Results and Conclusions. For most of the analyzed compounds, the highest yields were obtained by ultrasound assisted extraction. The highest temperature during the ultrasonification process (60 °C) increased the efficiency of extraction, without degradation of polyphenols. UAE easily arrives at extraction equilibrium and therefore permits shorter periods of time, reducing the energy input. Furthermore, UAE meets the requirements of ‘Green Chemistry’.
