Abstract:
The authors investigated the effect of intensive mechanical processing (dispersion) parameters for burdock roots (Arctium lappa L.) in a planetary activator mill on the degree of grinding, yield, and composition of water-soluble extractive substances. Experiments were conducted at reactor speeds of 1395; 1820 и 3200 rpm, with processing times varying from 1 to 10 min. Using gravimetric methods, spectrophotometry, electron microscopy, IR spectroscopy, and elemental analysis, the authors established that optimization of dispersion modes ensures the formation of nano-sized particles (77–350 nm) and significant intensification of the extraction of biologically active substances. The maximum yield of water-soluble extractive substances (65 %) and the polysaccharide inulin (49.2 %, an increase of more than 2-fold) was achieved at a reactor rotation speed of 1820 rpm and a processing time of 5–7 min. It was shown that with an increase in the mechanical processing time to 7–10 min, mechanochemical oxidation processes develop along with physical dispersion, identified by the appearance of absorption bands of carbonyl and carboxyl groups in the IR spectra of water-soluble extractive substances, as well as an increase in the spectral coefficients D3400/D1400 и D1080/D1400. The elemental composition of burdock roots is characterized by high oxygen (47.9 %) and carbon (37.9 %) contents, while primarily Ca, K, Si, and Fe represent the mineral complex. The obtained results confirm the potential of using intensive mechanical processing for the deep processing of plant materials, allowing not only to increase the yield of target components but also to specifically modify their functional properties to create new functional food ingredients, nutraceuticals, and biomaterials.
