In the course of research, the shelf life of a functional beverage based on plant raw materials was determined. To determine the shelf life the method of accelerated shelf life testing based on the Arrhenius model was used. As a controlled indicator, the concentration of anthocyanins is selected, which determine the functionality of this beverage. The test was carried out at a temperature of 50 degrees Celsius. The control sample was stored at a temperature of 20 degrees Celsius. Fixing the value of anthocyanins was performed every 3-4 days. As a result, the critical value was the value of anthocyanins on day 14. It fell by 55% from the original value. Thus, according to the calculations and the law of Arrhenius, the shelf life of the drink was 3.7 months.
