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

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 the article we have developed a new technology for producing linseed oils by mixing linseed seeds of different varieties and method of calculation of the corresponding mixture. It also shows a comparison of indicators of the quality of the oils of specified fatty acid composition obtained by blending flax seed varieties and blending finished with linseed oils

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

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

THE INFLUENCE OF METHODS USED TO PREPARE FLAX SEEDS FOR PRESSING ON THE OUTPUT AND QUALITY OF OIL
DescriptionAnalytical survey has revealed that technologies of flaxseed oil processing used nowadays are able to produce technical flaxseed oil if the output is high and food flaxseed oil if the output is low. The objective of this work is to reason the most effective method to increase the output of food flaxseed oil while keeping its quality high. In this article a comparison has been made between single cold pressing of flaxseeds without preliminary preparation with microwave processing, as well as traditional (conductive) heating with traditional heating under vacuum. The object of the research is samples of flaxseeds (high quality variety VNIIMK-620 which contains 56.28% of linolenic acid in its fatty acid composition. It has been established, that the use of preliminary microwave processing enables to increase the output of oil compared to a single cold pressing without any processing, whereby the mass content of oil in oil cake can be reduced by 2.2%. At the same time the indicators of acid number and peroxide value are increased by 0,05 mg KOH/g and 0.37 mmol of active oxygen/kg correspondingly. Preliminary traditional heating of seeds before cold pressing enables to increase the output of oil, though not considerably, compared with preliminary microwave processing. At the same time the changes in acid number and peroxide value are similar to cold pressing with microwave processing. The use of vacuum when heating seeds in a traditional way does not influence the output of flaxseed oil but enables to decrease acid number and peroxide value to the level which is characteristic for the oil in original seeds. Thus, it is reasonable to use preliminary microwave processing under vacuum before cold pressing with the view to produce food flaxseed oil of high quality in terms of oxidative deterioration and the increase of its output
