Effects of unconventional raw materials on the quality and quantity of volatile organic compounds forming the flavor of cookie samples

The article examines the influence of unconventional raw materials on the formation of volatile organic compounds that form the aroma of oatmeal cookies. The authors used paize flour, flaxseed flour, nigella oil, and sorghum sugar syrup as non-radioactive raw materials. Instrumental assessment of the qualitative and quantitative content of volatile organic compounds in product samples was carried out in the NIL VGUIT (Voronezh) on the laboratory odor analyzer "MAG-8" (manufactured in Russia) with the methodology "electronic nose". Sensors based on piezo-quartz resonators of the OAV-type with base oscillation frequency of 10,0-14,0 MHz with different film and nanostructured sorbents on the electrodes were used. From all the data taken together, it can be concluded that the change in formulation has a significant impact on the qualitative and quantitative composition of the gas phase samples over the cookies samples.Sample 1 with a wheat flour to ration ratio of 40:60 was found to be more similar in flavor to oat cookies (reference sample), whereas at 60:40 (sample 2), flavor of Gothic payza variety flour differs as much as possible from sample 1 with qualitative and quantitative composition of the smell and will be evaluated by the tasters in a different way. Yet the aroma is pleasant and has tart and spicy note.
