Description
In this article we have investigated fatty acid composition of oil made of flex seeds of VNIIMK-630 traditional variety and new selected SURPRISE variety. The comparative analysis of composition and factional composition of tocopherol in oil made of these seed varieties has been carried out. We studied changes in acid and peroxidation numbers when flex seeds are stored in the dry condition

THE INFLUENCE OF CONDITIONS OF PRESSING IN FLAX SEEDS ON THE OUTPUT AND QUALITY OF OIL
DescriptionThis article studies technologies of cold pressing in flax seeds of low-linolenic and ordinary sorts. We studied how conditions of flux seeds pressing influence acid and peroxide values of oil as well as fraction of total mass in oilcake. The results of experiment have been mathematically processed

DescriptionThe article presents the results of diagnosis of soybean plants with sulfur, molybdenum and boron in a Western Ciscaucasia on leached chernozem (black soil). The soil testing has shown that the availability of sulfur in the experimental plots is low (2,10-7,02 mg / kg), molybdenum - average (0,20-0,28 mg / kg), boron - low to high (0, 22-0,63 mg / kg). The sulfur content was optimal in 2013 (2309 mg / kg), molybdenum - 2013 and 2014 (1.11 and 0.94 mg / kg) and the boron content was high (65,2-94, 1 mg / kg) in soybean plants. The soybean plants needed sulfur fertilizer in 2012 and 2014, molybdenum - in 2014, and boron fertilizers are not needed, according to the functional diagnosis. The results of various methods of diagnosis coincided with the response of soybean plants for foliar application: sulfur fertilizer increases the yield in 2012 and 2014 by 7.1 and 8.9 %, molybdenum also in 2012 and 2014 - by 6.0 and 10.0 %. Boron fertilizers in 2014 increased soybean yields (17.1%), despite the lack of need for soybean plants in Bor. So, the method of functional diagnostics is more accurate than chemical soil and plant diagnostics

DescriptionIn the article, we have revealed the efficiency of foliar sulfur (potassium sulfate 250, 500, 1000 and 2000 g/ha), molybdenum (celik molybdenum 125, 250, 500 and 1000 ml/ha) and boron (solubor DF 0,5, 1,0, 2,0 and 4,0 kg/ha) fertilizers in various doses of soybean growing on the leached black soil of Northern Ciscaucasia which are based on studies in central part of the Krasnodar region in 2012-2014. The Vilan is a soybean variety most common in the Krasnodar region; therefore it was taken as the research object. It was established that 250 g/ha is the most effective dose of sulphur fertilizer. It’s provided a yield increase by 0,13 t/ha and increase collection of protein and oil (52,9 and 21.1 kg/ha, respectively). Soybean yields were increased by the application of molybdenum fertilizer in a dose of 250 ml/ha by 0,10 t/ha with increasing collection of protein 45,8 kg/ha. Boron fertilizer increased sum of beans and seeds. Variant of 0.5 kg/ha provided yield increase of 0.08 t/ha, but it was 0.26 t/ha in dry 2014

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

Description
To determine the mass fraction of linolenic acid in flax seed oil the authors developed a rapid method based on the pulse method of nuclear magnetic resonance with the use of NMR analyzers low resolution. This method has some significant advantages compared with the known method on the basis of chromatographic method for the determination of the mass fraction of linolenic acid in the oil extracted from the seeds of flax, namely, does not require additional sample preparation (extracting oil by solvent), eliminates the use of toxic chemicals, requires a much lower investment of time to conduct a single analysis, highly automated, and eliminates the influence of human factor on the research results. The method is based on the revealed correlation between the weighted average time spin-spin relaxation of protons contained in the triacylglycerols of the oil of the flax seed, and a mass fraction of linolenic acid in the seed oil at a temperature of 23ºc. In article results of research of influence of temperature on the weighted average time spin-spin relaxation of protons contained in the flax seed oil. Installed directly proportional linear relationship between the temperature of flax seeds and measured the average time spin-spin relaxation of protons oil contained in the flax seeds with the correlation coefficient is 0,930, the temperature change of the sample of seeds at 1 ° C leads to the change of the coefficient is 0.011 kt. The developed methodaccuracy in the temperature range from 20 to 26 ºC
