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

EXPANDING THE RANGE OF GLUTEN-FREE FLOUR CONFECTIONERY PRODUCTS BASED ON BUCKWHEAT AND QUINOA
DescriptionExpanding the range of flour confectionery products for people suffering from intolerance to wheat protein is relevant in the circumstances of import substitution. The domestic market of gluten-free confectionery products fully meets the demand of this category of people, which are dominated by sweet tooth children, requiring constant variety of confectionery. Therefore, the purpose of the work, which consists in expanding the range of pastry products based on buckwheat and quinoa, is relevant. The study presents a shortbread recipe based on buckwheat flour with different dosages of quinoa, a block diagram of the production and evaluation of the quality of the finished confectionery. Sensory evaluation of quality was carried out by a tasting analysis by a special system of scores: quantified indicators of quality - color, taste, smell, surface, shape and form in a break - is presented in the form of balls, followed by mathematical processing. We have defined physical and chemical indicators of quality biscuits, including moisture, alkalinity, absorption, fat and sugar content. Based on the assessment of quality of gluten-free shortbread we have set the optimal ratio of buckwheat flour and quinoa is equal to 70:30. The developed formulation will expand the range of gluten-free flour confectionery and can be adapted to the process and the equipment installed on the existing confectionery businesses

THE RESULTS OF THE REFORM OF THE EDUCATION SYSTEM IN RUSSIA
DescriptionOne of the main tasks is the improvement of the education system, the quality of which depends on the level of economic development of the country. In Russia, for more than 10 years there has been a continuously reformed educational system. This is due to Russia's accession (in 2003) to the group of countries – participants of the Bologna Declaration, involving the convergence and harmonization of education systems in European countries with the aim of creating a unified educational space. The article describes the main positions that are subject to a quality assessment of education from foreign universities; we have also revealed the reasons for the low world rating of Russian universities. At present, the education system of the country should facilitate accelerated development of the economy of the state in the first place. This work reveals the shortcomings of the main reforms related to the implementation of CSE in secondary educational institutions, the bureaucratization of the higher education system that resulted in time reduction of contact of the work of students with teachers, and as a result – deterioration of quality of preparation of graduates. We have also revealed the causes of the current situation and the main directions that will contribute to the development of the education system in Russia. These areas are the development of: a strategic plan for the development of higher education; a training system worthy contingent of higher education institutions; an effective system of preparation of students and evaluation of the quality of their knowledge and labor potential; a system of training for scientificpedagogical personnel and improving their qualification; assessment criteria of effectiveness and ability of educational institutions to provide quality knowledge

06.00.00 Agricultural sciences
DescriptionThe modern cattle breeding in Russia is characterized by dynamic development, development of intensive technologies, increase in production, but at the same time, there are problems of increase in production of milk due to increase of dairy efficiency of cows at the most effective manifestation of the available level of their genetic potential. For the solution of this problem, i.e. for genetic improvement of dairy cattle, creation of new breeds, intra pedigree or zone types, more than 100 thousand of bulls with high genetics, and also 430 thousand heifers were delivered to Russia for the last 10 years. In this regard, the purpose of our researches was to study the level of genetic potential of dairy cows in breeding farms of "Nasha Rodina" of Gulkevichsky region, Vasyurinsky milk farm of Dinsky region, the Firm «Agrocomplex» of Vyselkovskiy region (Gazyrskoye enterprise), "Urozhay" of Kanevskoy region from 2000 to 2014, by using bulls of Golshtinsky breed. Researches have shown that in farms of the Krasnodar region producers with the high level of potential from 10791,0 kg to 12045 kg on milk were yield used on a breeding uterine livestock; from 4,22 to 4,40% of fat; from 3,32 to 3,49% of protein in milk. As a result the level of potential of daughters of bulls and cows in herds of farms was from 7774 to 9144 kg of milk; from 3,89 to 4,05% of fat; from 3,26 to 3,67% of protein in milk. However, genetic potential of new generation of animals is shown not completely. It is influenced by partial compliance of the created technological conditions of biology of animals, and indicators of breeding value of producers, with their prepatent indicators. Calculations of breeding value indexes of bulls – fathers of cows in the herd of "Urozhay" have shown that each bull has its breeding value, an ability to transfer the qualities to posterity. Bulls of Golshtinsky breed of red – motley color ( Pan 2037 and Tulup 78160689), by results of comparison of milk yields of daughters, mothers and contemporaries, had negative prepatent indexes of milk yield and milk protein content (according to F.F. Eysper and V. Sidorova). The data confirm the need of carrying out an obligatory index assessment of bulls before their use on the farm in order to avoid receiving descendants with low dairy efficiency
