Powdered intermediate of yacon as a prebiotic ingredient of bakery products

The current stage of consumer market development is described by increasing interest in healthy food products, specialized, and functional purpose foods. In these conditions, the solution of the problem of the correction of the composition, while preserving the taste, aroma and other consumer characteristics, is of particular importance. The complex of organoleptic, physicochemical, and microbiological tests confirmed the technological feasibility of using yacon powder in bakery technology made of a mixture of rye and wheat flour. The studies on the composition of yacon powder, its effect on the growth and development of lactic acid bacteria demonstrate the possibility of using yakon powder as a functional food ingredient with a prebiotic effect. The results obtained are confirmed by a comparative characteristic of the quality and composition of bread made of the mixture of rye and wheat flour of the control and experimental samples with the addition of powdered yacon semi-finished product.
