Muratova E.I., Dvoretsky S.I., Smolikhina P.M.Optimization of Confectionary Composition // Scientific article. Journal "Transactions of the TSTU", vol. 21 , Tambov. TSTU publisher house , 2015. (pdf-file) Abstract: The aim of this study was to develop new recipes of confectionery products for functional purposes in accordance with predetermined criteria of optimization. The paper formulates the objective of recipe optimization relating to the class of multicriteria nonlinear programming problems, and shows the algorithm developed for its solution. As an example, the article gives the formulation and solution of the problem that involves designing candy recipes with mixed jelly-whipped body. The choice of ratio between layers of combined body enriched with functional ingredients was carried out according to four criteria (energy value, carotenoids, dietary fiber, and the cost price of the finished product) under the given constraints on technological and consumer product characteristics. The solution of the multicriteria problem identified a number of effective points belonging to the area of Pareto. The final choice of possible options was made on the basis of the ratio "price–quality" tailored to meet the daily requirements of micronutrients and organoleptic evaluation of the product. Adjustment of the layers provides a wide range of jelly-whipped candies with original organoleptic characteristics and a given set of micronutrients that can be recommended for different categories of the population. Varying the composition of recipe mixtures from possible set of raw ingredients, enriching them with micronutrients, can influence on the physiological effect of finished products. The proposed approach can be recommended for recipe designs of complex multicomponent food systems with specified set of characteristics in terms of multiple alternatives of ingredient composition and interchangeability of raw materials.

steps, scientifically defining the quality of a finished product. The object of drying were rhizomes and roots of Podophyllum emodi, being a source podophyllotoxin. Podophyllotoxin is used as starting material in the synthesis of anticancer drugs. Experimental studies on drying were conducted in the range temperatures from 40 up to 70 °С and velocity of drying air from 2 up to 5 m/s. To study the process of heat pump
drying we used an experimental setup with recirculation drying agent. The obtained data will be used for further studies: selecting process parameters of heat pump drying and working out practical recommendations for application in the industry.
