Abstract. It was scientifically substantiated and developed a formulation of drink for athletes based on mineral water, enriched with natural metasilicic acid and amino acids with a branched carbohydrate chain (AABCC). The studies were conducted in 2017–2018. The composition of the drink included natural mineral drinking water “Ardvi”, fructose, complex food additive Aspartame, acidity regulator (citric acid), AABCC, sodium citrate, flavoring material “Kiwi”, preservatives (sodium benzoate and potassium sorbate). The quality of the mineral water was preliminarily evaluated, then the main ingredients of the drink and their quality were determined. Analyzes were performed in five replications. Beverage production involved the following stages: acceptance of raw materials; mineral water preparation; consecutive preparation and introduction of components of blending syrup, preparation of the drink; bottling, corking, rejection, labeling, packaging, and transfer of finished products to the warehouse; storage and transportation of finished products. The drink was prepared by means of a synchronous mixing plant from blending syrup and prepared water in the ratio of 1:5 (other dilutions were allowed). The finished drink was bottled in polymeric materials such as PET. The appearance of the drink is clear liquid without sediment and foreign inclusions, colourless, with a fruity taste and aroma of kiwi. A slight natural precipitate of mineral salts is allowed. After 14 months of storage, organoleptic characteristics, the main ionic composition, the amount of the biologically active component of the drink – metasilicic acid (53.4 mg/dm3) and the content of AABCC (glycine – 0.10 g/100 mL; valine – 2.1 g/100 mL; isoleucine – 1.3 g/100 mL; leucine – 0.30 g/100 mL) did not change significantly. The values of microbiological indicators of the drink after production and storage for 14 months corresponded to the standard. Drinking 200 mL of the drink provides from 72 to 93% of the athletes’ needs in silicon and up to 95% in AABCC. The recommended shelf life is 12 months at a temperature from 0 to 25 Celsius degrees and relative air humidity not higher than 85%.
