The development of targeted beverages is a priority for healthy eating. Plant raw materials containing a wide variety of biologically active substances are used for their production. The presence of these ingredients helps to improve many physiological processes in the body, as well as to increase its immune status. The high efficiency of ultrasonic effects on various technological processes was confirmed by numerous studies. Ultrasonic extraction was carried out at t = 20 ? and an ultrasonic wave frequency of 22 kHz. As a result of the research, it was found that the equilibrium state is achieved within 15 minutes with ultrasound exposure. Natural raw materials, their chemical composition and the influence on the human body were studied in the work to develop new beverages recipes. The selected ingredients in a certain quantitative ratio made it possible to obtain beverages with improved bio-corrective properties, which allows satisfying the daily requirement of the human body for biologically active substances. Ultrasonic exposure has a positive effect on the organoleptic characteristics of the beverage and the aftertaste, as proved by the comparative organoleptic evaluation of the samples. The functional properties of the beverages developed were confirmed experimentally. The following was determined in the beverages: macronutrients content, antioxidant activity, vitamin C content, shelf life duration. The ultrasonic extraction method application in the technology of beverages manufacturing allows: to reduce the preparation time by half, to reduce the amount of raw materials by 15%, to increase the content of macronutrients by 45%, to increase the content of vitamin C by 35%, to increase the antioxidant activity by 45-50%, to increase storage stability by 50-60%, to improve organoleptic characteristics. The results obtained prove the intensifying effect of ultrasonic exposure in the production of functional beverages.

Chinese bayberry (Myrica rubra Sieb. et Zucc.) is an economically important medicinal plant with multiple uses. Two varieties ‘Dongkui Oriental Pearl’ (Dongkui for short) and acuminata ‘Nakai’ (Nakai for short) were used to compare and evaluate the antioxidant activities of hydroethanolic extracts of the fruit using ultrasonic and stirring extraction methods. Dongkui bayberry fruit extract (BFE) prepared using the ultrasonic method exhibited a significantly higher value for the total phenolic content (TPC) and had lower 50% inhibitory concentration (IC50) values of scavenging activities against 1,1-diphenyl-2- picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid (ABTS), and hydrogen peroxide (H2O2), as well as reducing power compared to the other treatment. The TPC of the BFE was significantly correlated with its DPPH, ABTS, and H2O2 radical-scavenging and reducing power activities. Dongkui BFE at a concentration of 0.25 mg/mL exhibited significantly greater protection of RAW 264.7 mouse macrophages against H2O2-induced damage and lipopolysaccharide (LPS)-stimulated nitric oxide production by macrophages, and it displayed remarkable inhibitory effects compared to the other extracts using the ultrasonic extraction method. Furthermore, compared to the Nakai BFE, macrophages exposed to the Dongkui BFE by the ultrasonic extraction method significantly inhibited LPS-induced production of tumor necrosis factor-α at a concentration of the extract of 0.25 mg/mL. The antioxidant properties and anti-inflammatory and protective effects of BFE prepared by stirring and ultrasonic methods are discussed for the first time in this study.   ********* In press - Online First.

Platymonas Subcordiformis

Five extraction methods were used to extract extracellular polymers (EPS) from Platymonas subcordiformis. Results suggested that the extraction efficiencies of EPS decreased as followed: cation exchange resin (CER) > ultrasonic extraction> heating (80°C) > EDTA > centrifugation. CER method was the most effective in the EPS extraction from P. subcordiformis with the highest amount of EPS and the lowest cell lysis, while the ultrasonic extraction method was not suitable to extract EPS for its obvious cell lysis. In addition, heating (80 °C) was used to investigate EPS formation of P. subcordiformis. Results showed EPS amount increased at the increased incubation time when the nutrients were enough whereas the ratio of EPS components remained unchanged in the growing cycle.
