Green Approach to Intensify the Extraction Processes of Substances from Plant Materials

Abstract

The principles of sustainable development and green chemistry are priorities in the development of new technologies for the extraction of useful biologically active substances, for example, in the manufacture of medicines. The processes of extracting substances from plant raw materials have many applications. Intensification of such processes, reducing their duration, energy consumption and consumption of the extractant is urgent. The object of the reseach is the green approach to intensify the extraction processes of polysaccharide substances from plant materials. The research methodology was experimental with statistical data processing. In the field of experimental research was the process of the influence of pulsed, alternating and direct current on the intensity of aqueous extraction of polysaccharides from plant materials. The high efficiency of intensification of extraction by a pulsed electric field was studied. The process can reduce the time for obtaining water-soluble polysaccharides by 3 times in comparison with traditional pharmacopoeial convection methods and reduce energy consumption by 20 times. The significance of the pulse current parameters for effective extraction was determined: the referred pulse shape, the frequency of the pulse current for extracting the maximum amount of water-soluble polysaccharides, the pulse duration, and the optimal processing time. The green approach to the use of a moderate electric field of pulsed current to accelerate the extraction of biologically active substances is the basis of the method of intensification of other traditional mass transfer processes for the sustainable development of technology.

The Genus Hyssopus: Traditional Use, Phytochemicals and Pharmacological Properties

“…One of the promising methods for intensifying extraction is the electrophysical method, where the material is treated with a pulsed electric field, which can be applied to substances that are polar dielectrics in physical nature. The authors of [ 22 ] presented the results of the intensification processes of polysaccharides from H. officinalis under the influence of electric current. The energy consumption for the H. officinalis extraction process was proved to be intensified with a pulsed electric current that was significantly lower than extraction via convection heating.…”

Optimizing Energy Efficiency of Dielectric Materials’ Electrodischarge Dispersion as One Sustainable Development Green Trend

“…Increasing the energy efficiency of production processes is closely related to minimizing the impact on the environment and is one of the priorities of the concept of sustainable development [1][2][3][4][5][6][7][8], energy modeling [9][10][11][12][13], and digital technologies [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. The focus of attention in this study was the processes of electric discharge in liquids with respect to modern green trends in the development of science and production, in particular, the search for parameters to optimize the energy efficiency of these processes [12,13,[32][33][34][35][36].…”

Synergy Effect during Water Treatment by Electric Discharge and Chlorination

“…Much attention is paid to both traditional methods of removing heterogeneous impurities of biological origin (chlorination, ozonation, ultraviolet radiation treatment), and non-traditional ones (e.g., plasma and membrane technologies). Attention should be paid to electrical methods that have demonstrated their effectiveness for the intensification of various processes [14][15][16].…”
