Theoretical and experimental base preparation for creating a sports beverage with rehydration and hondroprotective action

The paper shows theoretical and practical prerequisites for the formulation of a sports beverage recipe that has rehydration and chondroprotective properties. For this purpose, two types of dairy raw materials were chosen for the objects of research: curd whey and permeate, obtained with industrial skim milk ultrafiltration, as well as aqueous solutions of chondroitin sulfate.
