MATHEMATICAL MODELING OF OAT BISCUITS FORMULA ENRICHED WITH PRODUCTS OF TOPINAMBUR PROCESSING

Oat biscuits are popular among the population of various age groups. They have good organoleptic properties, but at the same time, high sugar content with low protein and biologically active nutrients. The disadvantage of oat biscuits as well as wheat flour cookies, is the imbalance in micronutrient composition against the background of high energy value and sugar content. The authors substantiated the recipe for oat biscuits enriched with Jerusalem artichoke processed products – puree and syrup, taking into account the requirements of “healthy eating”. Jerusalem artichoke is a valuable source of complex carbohydrates, vitamins, minerals; it is widely used in the nutrition of patients with diabetes mellitus, for the correction of metabolic disorders, in the production of functional and specialized food products. The optimization of the recipe for oat biscuits has been carried out using the generalized desirability function. When developing new recipes for food products, organoleptic properties and quality indicators of model samples have been taken into account. The solution of the problem of mathematical programming was carried out in MathCAD v.15. Statistica v.10 was used for regression analysis. For the first time, regression equations have been obtained that describe the dependence of organoleptic indicators and swelling of oatmeal cookies with Jerusalem artichoke on the mass fraction of prescription components. The recipe for oat biscuits for specialized purposes has been determined, providing optimal quality characteristics of the finished product, consisting of (wt %): oat flakes – 55, Jerusalem artichoke (puree) – 20, Jerusalem artichoke syrup – 6, mineral water – 10, dry whey – 9. The proposed approach is effective in modeling recipes for flour confectionery products, including functional and specialized purposes, and is a methodological basis for finding new technological solutions in the food industry and public catering.
