| Popis: | The article presents the results of a study of the formation of aroma-forming substances in bakery products with the addition of paize flour to the recipe. Instrumental assessment of the smell of products was carried out on the smell analyzer «MAG-8» with the methodology «electronic nose». The variants of the experiment differ in the content of paize flour 15–20%, according to the method of preparing the dough: the biological method of loosening – bread, bread sticks, unleavened dough – bread skewers. With the help of an «electronic nose», it was instrumentally proved on the MAG-8 odor analyzer that for the samples submitted for testing, the smell is correct and not pronounced, aromatic additives and odor enhancers, as well as the presence of destructive processes and mold formation are absent. When comparing the volatile compounds in the samples quantitatively, it should be noted that since the semi-finished bread undergoes longer fermentation than breadsticks, the content of alcohols and ketones is 22% higher, and compared with bread skewers, where there is no fermentation process, they are 93% more, a similar picture with acids. However, when comparing the content of individual components in samples, especially oxygen-containing compounds, they are almost twice as large in the absence of a biological method of loosening in bread skewers. For consumer evaluation, such changes are not significant for those samples in the formulation of which the content of paize flour is no more than 15% and recognized by consumers according to organoleptic indicators. |
