THE INFLUENCE OF ULTRASOUND CAVITATION ON THE EXTRACTION LEVELOF BIOLOGICALLY ACTIVE SUBSTANCES FROM VEGETATIVE RAW MATERIALS

 The articleis devoted to a research of action of a low frequency ultrasound (22 ± 1,65kHz) on an extraction level biologically of the active components fromvegetable raw materials. For the first time Betalain was selected from beet (Betavulgaris L.), as is known, this group of connections has powerfulanti-inflammatory and antioxidant effects. Some researches are specified thatbetalain is capable to neutralize toxins and to support natural process of adetoxication of cells and also reduce amount of the enzymes causinginflammation. During extraction process of colorants together with them theaccompanying substances which then to have an adverse effect on properties ofdye are derived. For this reason allocation of pigments from raw materialswithout decrease in technological and physiological properties is a difficulttask Experimentally it is justified that for effective extraction biologicallyof the active agents ultrasonic influence in the mode is applicable: power is180 W, time of influence – 5 min. Has been set, this mode of ultrasonicinfluence is saving on average on 8 … 12 % of a betanin of the directextraction beet juice. Application of lyophilic drying of juice allows to save thebiological active components and their ratio in the extract. Spectrophotometricmethod of a research of extracts gives an objective assessment to stability ofbetalanin in case of influence of an ultrasound of different power andduration. The absorption maximum is reached in case of wavelength – 477nanometers, power – 70 % during 1 … 3 minutes and 538 nanometers, power – 50and 70 %, 5 and 1 minutes. In technology of dry water-soluble extract from vegetativeraw materials, it is possible to select processes of maceration, thelow-temperature and ultrasonic processing which give the substantial increaseof efficiency of extraction of biologically active components.
