Abstract

In this experimental work, the method of ultrasonic extraction was used to intensify the preparation of the extract. The maximum extraction of nutrients during the preparation of extracts with the maximum preserved initial bio-corrective effect on the body is possible with the help of ultrasonic extraction. The article presents experimental data on the determination of the content of macronutrients in the obtained drinks, such as potassium, sodium, calcium, magnesium, which, in comparison with other nutrients, are the most stable during the production and storage of drinks. As a result of experimental studies, it was found that, in comparison with control samples, the content of macronutrients in drinks prepared using the ultrasonic extraction method increases by 45 %, which makes up the body’s daily need for these nutrients from 3 % to 25 %. In drinks prepared using ultrasonic extraction, the vitamin C content increases by 50 %, and meets the daily requirement by 100 %. The values of antioxidant activity in samples prepared using the method of ultrasonic extraction exceed the control samples by 45-50 %. The studies carried out prove the high biological value of beverages.
