Description
The article presents the comparative characteristics of the current (diffusion) and developed (diffusion-press) sucrose extraction technology from sugar beet cossettes. We have presented the graphs of the influence of raw juice pumping value on its cleanliness and residual content of sucrose in partially desugared beet cossetes, the influence of partially desugared beet cossetes pressing power on residual content of sucrose in the pressed pulp and losses of sucrose with pressed pulp and also the technological scheme and regimes of diffusion-press extraction of sucrose from sugar beet cossettes. The criteria for determining the boundary parameters of diffusion and press sucrose extraction stages are identified. The comparative assessment of technological and economic indicators of the existing and the developed technologies of sucrose extraction from the beet cossettes is shown. The developed technology allows reducing raw juice pumping value simultaneously increasing its purity, thereby providing reduction of auxiliary materials and energy resources consumption, as well as increasing sugar yield. The technology of diffusion-press extraction of sucrose is implemented on 2 sugar beet factories of the Russian Federation. The economic effect from its implementation is more than 45 mln. rubles

DEVELOPMENT OF ECOLOGICALLY SAFE EXPRESS-METHOD FOR QUALITY EVALUATION OF SOYBEAN LECITHINS
DescriptionThe 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

Description
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

ANTIOXIDANT ACTIVITY OF FOOD ADDITIVES DERIVED FROM SECONDARY PLANT RESOURCES
DescriptionThe accumulation of free radicals in the human body in excessive quantities is one of the reasons that are known to cause many dangerous diseases and aging. To reduce the negative impact of free radicals to the body is possible through regular consumption of food products enriched with nutritional and dietary supplements containing natural antioxidants such as phenolic compounds, vitamin C, vitamin E and β – carotene. Scientists of federal state budgetary scientific institution "Krasnodar research Institute of storage and processing of agricultural products" have developed a technology for production of food additives from secondary materials generated during the processing of apples and pumpkins. The article presents data characterizing the antioxidant and antiradical activity of food additives derived from secondary plant resources developed and known technology. It is established that the antioxidant activity determined by the amperometric method, and the antioxidant (antiradical) activity, determined by DPPH method, supplements, "Powder apple" and " Powder pumpkin" obtained by the developed technology, is almost 1.5 times higher in comparison with antioxidant and antiradical activity of food additives, obtained by known technologies, because of higher content of antioxidants in the developed supplements. It has been established that the expression of antioxidants and anti-radical activity of food supplements obtained from secondary resources on the developed technologies, can be positioned in a number of (descending): "Powder from the seeds of grapes" → "Apple powder" → " Pumpkin powder"
