MATHEMATICAL DESIGN OF POLYCOMPONENT DRINKS WITH A BALANCED NUTRIENT COMPOSITION

Abstract

Based on the principles of food combinatorics using the methods of mathematical and computer simulation, formulations of polycomponent drinks based on dairy and vegetable raw materials were developed. The drinks were cow's milk, bananas, spinach and pumpkin were used as plant material and chia seeds were used as a source of unsaturated fatty acids. Using mathematical planning, the criterion equations for beverages characterizing the maximum content of basic nutrients have been formed. Computer simulation of beverage recipes was performed in Excel Solver in a Microsoft Excel spreadsheet, which formalized qualitative and quantitative indicators of balanced nutrients. In computer-aided design, optimization for each selected indicator was used by paired with the recommended nutrient content of FAO / WHO. Formulations of pumpkin, spinach and banana beverages were obtained in which the content of basic nutrients was 18,889 g, 17,664 g and 21,329 g per 100 g, respectively. Analysis of the chemical composition showed that the ratio of proteins: fats: carbohydrates is 1: 1.45: 3.03 for the drink "Pumpkin", 1: 1.34: 2.57 for the drink "Spinach" and 1: 1.5: 4 , 27 for the Banana drink. The ALST method determines the storage conditions of developed beverages, taking into account changes in sensory and microbiological parameters. Determination of optimal storage conditions by estimation of changes in organoleptic parameters makes it possible to state that the developed beverages will be competitive in the establishments of the restaurant industry of Ukraine. A study of changes in the microbiota of finished beverages within 4 hours at (4 ± 2) ° C in a closed glass container showed that, in the presence of conditionally pathogenic microorganisms, the beverages meet the current regulatory requirements. The integrated approach to the production of multicomponent beverages can be used by any market operator to produce not only beverages but also various food products.
