SUBSTANTIATION OF DRINK CONCENTRATE FORMULATION BASED ON HEMP PROTEIN FOR SPORTS NUTRITION

The purpose of the study is to experimentally substantiate the formulations of beverage concentrates based on vegetable protein for sports nutrition. The objects of the study were beverage concentrates based on hemp protein; drinks prepared for consumption. The following stages of scientific research were carried out, namely selection of components of beverage concentrate formulations was conducted; the organoleptic and physico-chemical indicators of the quality of concentrates and drinks obtained from them were analyzed; the stability of the quality and safety of beverage concentrates during the recommended shelf life was studied. As a result of research, the compositions of beverage concentrate formulations were substantiated, including vegetable protein, antioxidant, thickener, flavoring agent and flavoring food additives. The high nutritional value of the resulting drinks, the high content of protein and digestible carbohydrates have been experimentally confirmed. Accordingly, the drinks obtained from these concentrates can be classified as protein-carbohydrate products for sports nutrition. It has been established that the quality and safety of the developed beverage concentrates comply with the regulated requirements, as well as the high preservation of their properties throughout the regulated storage period. An increase in the moisture content in the samples of concentrates (up to 8.8 %) and an increase in titratable acidity (up to 3 degrees) were established, the obtained values were within the regulated values. During the storage period of 4 months at elevated temperatures, the processes of oxidative deterioration proceeded to a small extent, the increase in acid and peroxide number was no more than 30 % relative to the initial value. The results of scientific research are recommended for implementation at enterprises specializing in the production of food products from industrial hemp seeds.
