The article presents a comparative assessment and peculiarities of nuclear magnetic relaxation characteristics of rapeseed and sunflower lecithin. It was established, that lecithin’s nuclear magnetic relaxation characteristics, namely, protons’ spin-spin relaxation time and amplitudes of nuclear magnetic relaxation signals of lecithin components, depend on content of oil’s fat acids and phospholipids, contained in the lecithin. Comparative assessment of protons’ spin-spin relaxation time of rapeseed and sunflower lecithin components showed, that for their identification protons’ spin-spin relaxation time of the lecithin’ first component at 40°C and 60°C temperature, when differences in values of protons’ spin-spin relaxation time of the sunflower and rapeseed lecithin’ first component are most obvious, should be used as an analytical parameter. Comparative assessment of amplitudes of proton’s NMR signals of sunflower and rapeseed lecithin components showed, that relations, established earlier for sunflower lecithin between mass share of phospholipids (substances insoluble in acetone) and the sum of amplitudes of proton’s NMR signals of the third and fourth components, cannot be applied to rapeseed lecithin; that is for the development of an express method for determination of mass share of substances insoluble in acetone (phospholipids) in rapeseed lecithin, it is necessary to carry out additional research with the purpose of clarifying the mentioned relations

The article analyzes the proprietary methods of processing of vegetable raw materials and secondary resources with the use of electromagnetic fields (EMF SHF). Analysis of the database of Rospatent World Intellectual Property Organization led to the conclusion that EMF SHF used in the processing of vegetable raw materials in the following processes: drying, reduction of microbial contamination (decontamination), juice production and extraction. It is established that the application of EMF SHF is the most effective in preparation for drying a plant raw material and not directly at the stage of drying, thus reducing the loss of heat-labile active compound in the drying process, and therefore obtain a finished product of higher quality and nutritional value. The patented methods of extraction of vegetable raw materials extraction process performed that extracting directly EMF SHF does not allow pre-hold inactivate enzymes contained in the raw material and lead to undesirable oxidative and hydrolytic processes, and hence a decrease in the yield of extractable substances in the extract and the deterioration of its quality . Therefore, as in the case of drying plant material, EMF SHF can be more effectively used in preparation for an extraction process. Based on the analysis, it was concluded that the relevance of developments in the field of technologies of processing of vegetable raw materials and secondary resources using EMF SHF at the stage of their preparation for such basic processes - drying, extraction, etc.

The article presents the results of the patent research in the field of modern production technologies of Inulin from plant material. It has been established that the differences of the currently known methods of production of inulin are concluded in selecting raw materials pretreatment inulin-containing modes type extractant and extraction methods, methods of purification inulincontaining extract and methods for producing the final product. A significant amount of Inulin production methods is based on use of freshly feedstock. A number of methods have been patented involving the extraction Inulin from plant raw materials previously stabilized by drying. In most of the methods, inulin extraction is carried out at elevated temperatures with water or aqueous salt solutions. Several technologies involve extraction with organic solvents at low temperatures. Have been patented several processes in which the extraction is replaced by a separation process using inulincontaining juice and physical and mechanical methods. Some of the known processes provide for the extraction process to further operations, such as blanching vegetable raw materials, sonication, vibration impact, processing enzymes. The most promising direction to improve manufacturing technology of inulin from fresh plant raw materials is to conduct research on the use of electromagnetic fields at microwave frequencies, the inactivating effects of which on enzyme systems is an established fact that, in turn, would eliminate the use of chemical agents for inactivation of oxidative enzymes. In addition, considering that more effective are the methods for the preparation of inulin from freshly harvested plant material, are relevant researches on development of innovative technologies to prepare it for storage and its storage, which will provide inhibition of unwanted biochemical and microbiological processes that occur during storage and lead to a loss of inulin

The article presents data, on the basis of which we have concluded that the oil and phospholipids contained in soy lecithins, the degree of unsaturation of fatty acids differ significantly from oil and phospholipids contained in sunflower lecithins, with differences in the degree of unsaturation of fatty acids of oil and phospholipids contained in sunflower and soy lecithins, leads to differences in the content of resonating protons, and, consequently, the level of amplitude values of NMR signals of protons of the investigated lecithins. It is established that the values of the amplitudes of the NMR signals of protons of each of the four components of sunflower lecithins differ from the values of the amplitudes of the NMR signals of protons the component of soy lecithins, which confirms the differences in the composition and content of fatty acids lecithins studied. Considering quantitative characteristic of mass fraction of substances insoluble in acetone, i.e. phospholipids, is the sum of the amplitudes of the NMR signals of protons of the third (A3) and fourth (A4) component, was built the graphical dependence of the mass fraction of substances insoluble in acetone, from the value of (A3+A4)/ASIS, % which is described by the equation (correlation coefficient R2 =0,9911) of the following form: y=0,8177x +2.52. Based on these data, we have developed a rapid method of determining the mass fraction of substances insoluble in acetone, soy lecithin, eliminating the use of toxic organic solvents, is environmentally safe, which is protected by RF patent for the invention

In recent decades, Russia has increased the demand for high oleic sunflower oil and, consequently, for the raw material from which it is derived – high oleic sunflower seeds. Currently existing methods of control of mass fraction of oleic acid in the seed oil of sunflower, have significant drawbacks, due to which sharply raises the question of the development of the Express methods of control of mass fraction of oleic acid. The study presents the results of determining the mass fraction of oleic acid in the oil of sunflower seeds, obtained by known methods (GC and ri), and developed a method based on NMR. The developed method of determining the mass fraction of oleic acid in sunflower seed oil has a number of advantages compared with the known: is not destructive (does not require the extraction of oil from seeds), does not require special sample preparation excludes the use of toxic chemicals, the analysis duration is 5 minutes, ensuring high representativeness of the sample, and the simplicity and automation of the analysis process reduces the requirements for qualifications of laboratory personnel. The developed method of determining the mass fraction of oleic acid in the oil of sunflower seeds can be carried out simultaneously with the determination of oil and moisture content of seeds on commercially available analyzers, but I hope it 1006М, which is currently applied at more than 250 companies of oil and fat industry
