Flax has been of great importance in Latvia for a long time. It is a sources of raw materials of valuable products – fibre and oil for national economy. The total content of oil and fatty acids in the 42 sorts of linseed was determined. The use of pre-seeding biostimulators (microorganism metabolite – Germin, microelements copper, zinc and boron) resulted in positive changes in total contents of an oil and unsaturated fatty acids (linoleic and linolenic) in the linseed of following generation was determined. Under the influence of biostimulators an augmentation of the yield of flax straw for 8–21% in comparison with control was observed. The yield of linseed increased for 6–28%, correspondingly.

Abstract The main goal of the rational use of bast fiber raw materials is to develop and apply optimal methods of its processing. Work on the creation of such technologies is carried out by leading scientists of the industry in accordance with three main areas of research: the search for ways to increase the yield of long flax fiber and improve its consumer properties by using various methods of ennobling; improving the methods to unfold bundles of technical fibers and obtain elementary bast fibers (cotonized fiber); and integrating the use of waste from primary processing of bast-fiber raw materials based on existing hydrolysis and thermal decomposition technologies. However, with some exceptions, the vast majority of research is limited to laboratory experiments, largely because the bast stem is a very complex composite. This raises a number of questions for researchers. In varieties and breeding samples with high fiber quality, the total fatty acid content is higher, and the ratio of total saturated acids to unsaturated acids is lower. A method for evaluating The selection material of the same flax based on fiber quality and lodging resistance is based on determining the total content of fatty acids and total lipids and the ratio of saturated to unsaturated fatty acids in flax stalks and seeds. Subsequent comparison of the obtained indicators of the studied selection material was according to the indicators of the standard variety.

The study was designed to investigate the chemical composition and the biological effects of G. parviflora and V. polyanthes ethanolic extracts in vitro. Total content of phenols, flavonoids and tannins was quantified by spectrophotometry; chemical characterization was permed by mass spectrometry (ESI (-) FT-ICR MS and APCI (+) FT-ICR MS analysis). Antioxidant activities were determined by FRAP and Fe2+ chelating methods. Extracts cytotoxicity was evaluated in human lymphocytes, sarcoma-180 (S-180) and human gastric adenocarcinoma (AGS) cells, by MTT assay. V. polyanthes presented higher total content of tannins and G. parviflora presented higher amount of phenols and flavonoids. Chemical characterization showed the presence of flavonoids, phenolic acids and sesquiterpene lactones in V. polyanthes extract, and steroids, phenolic acids and fatty acids (Poly Unsaturated Fatty Acids - PUFA) in G. parviflora extract. V. polyanthes extract stood out in the Fe2+ chelation test. G. parviflora extract did not present outstanding antioxidant results in the tested protocols. Both species showed a tendency to promote cytotoxicity in human lymphocyte cells. Regarding the antiproliferative effect, both species were able to reduce S-180 cell viability and G. parviflora extract showed high antiproliferative potential in the assay with AGS cells. These findings reinforce the medicinal use of these plants, as well as suggest their potential use for the development of new drugs and for the treatment of cancers.

Aldoxime Dehydratase

Currently, investigations of polymer-building blocks made from biorenewable feedstocks such as, for example, fatty acids, are of high interest for the chemical industry. An alternative synthesis of nitrile-substituted aliphatic carboxylic acids as precursors for ω-amino acids, which are useful to produce polymers, was investigated starting from biorenewable fatty acids. By hydroformylation of unsaturated fatty acids or unsaturated acids being accessible from unsaturated fatty acids by cross-metathesis reactions, aldehydes are formed. In this work, the hydroformylation of such unsaturated acids led to the formation of the corresponding aldehydes, which were afterwards converted with hydroxylamine to aldoximes. Subsequent dehydration by an aldoxime dehydratase as a biocatalyst or by CuII acetate led to the desired nitriles. Within this work, C7-, C9- and C11-carboxylic acids with a terminal nitrile functionality as well as a branched nitrile-functionalized stearate derivative were synthesized by means of this approach. As these nitriles serve as precursors for amino acids being suitable for polymerization, this work represents an alternative synthetic access to polyamide precursors, which starts directly from unsaturated fatty acids as biorenewable resources and avoids harsh reaction conditions as well as and by-product formation.

Biodiesel is defined as a fuel which may be used as pure biofuel or at high concentration in mineral oil derivatives, in accordance with specific quality standards for transport applications. The main raw material used for biodiesel production is rapeseed, which contains mono-unsaturated acids (about 60%) and also poly-unsaturated fatty acids (C 18:1 and C 18:3) in a lower quantity, as well as some undesired saturated fatty acids (palmitic and stearic acids). Other raw materials have also been used in research and the industrial production of biodiesel (palm oil, sunflower oil, soybean oil, waste plant oil, animal fats, etc). The historical background of biodiesel production, installed industrial capacities, as well as the Directive of the European Parliament and of the Council (May 2003) regarding the promotion of the use of biofuels or other renewable fuels for transport are discussed in the first part of this article. The second part focuses on some new concepts for the future development of technology for biodiesel production, based on the application of non-catalytic transesterification under supercritical conditions or the use of lipases as an alternative catalyst for this reaction.

The article is devoted to the study of the properties of bakery products, in particular the choice of the optimal concentration of flaxseed cake in baguettes in order to ensure maximum caloric content. It is known that bakery products are necessary for a person to ensure his health and ability to work. The range of food products, in particular bakery products, is constantly growing. The analysis of the range of bakery products showed that the market is experiencing a shortage of flour products for dietary, therapeutic and prophylactic and special purposes for different groups, and their share in total production does not exceed 1-2%. The problem of food production is becoming more complicated and exacerbated by increasing consumption, declining natural resources of food raw materials and the presence of specific anti-nutrients. The article describes the characteristics of anticancer substances in food, which belong to the groups of hytosterols and lignans. The article presents the results of optimizing the composition and properties of wheat baguettes with the addition of linencake, flaxseed meal. The recipe of bread with the inclusion of linen cake in the amount of 1 to 15% was developed. The nutritionalvalue and caloric content of bread are calculated, its characteristics are given according to the main organoleptic indicators of quality (product surface, color and thickness of the crust, as well as the condition of the crumb). The effect of the percentage of flaxseedmeal on the moisture and acidity of bread samples was studied. It is established that with the increase of the content of flaxseed mealthe protein content increases, the carbohydrate content decreases, the fat content and the amount of unsaturated fatty acids increase.As the content of linen cake in bread increases, the amount of unsaturated fatty acids increases and its caloric content decreases, andits nutritional value increases. The use of flax seeds and products of their processing in the formulation of bakery and confectionery products can increase their biological value and physiological efficiency due to the content of anticancer substances, fibers, micro- and microelements, proteins and essential amino acids. Trial laboratory baking of baguettes showed that the optimal content of linen cake is 5% by weight of wheat flour, which allows you to get bread that meets the standards and does not require changes in technological parameters, which are set for the product without additives.

Tall Oil

The article discusses the scientific and technical issues of the methodology for producing liquid biofuel from renewable raw materials of plant origin. As raw materials used wastes from the production of pulp and paper mills — tall oil. The purpose of the work was to study the process of obtaining and determining ways to use the product. The optimal conditions for obtaining biodiesel are determined. The processing of raw materials was carried out by heating it with methanol in a ratio of 1:0,3 at a temperature of 50–65 °C for 2 hours in the presence of 2 % catalyst. The product, after separation of the resulting intermediate, was finally washed with water from the catalyst residues. The process was controlled spectrophotometrically. Using gas-liquid chromatography with mass spectrometric detection, the complete chemical composition of the used raw materials of various degrees of purification was established. It is shown that the main content in the processed oil is represented by natural lipids. Their fatty acid composition is described, comprising more than thirty C10–C24 fatty acids. A general scheme for producing biodiesel, which is a mixture of fatty acid alkyl esters, has been developed. The product was obtained by chemical transformation in the presence of acid catalysts, followed by the formation of fatty acid methyl esters. The component composition of the obtained product, biodiesel, was studied and it was shown that it consists of a mixture of methyl esters of fatty acids more than 95 %. In biodiesel, more than two hundred organic substances are also contained in the form of an insignificant amount of microimpurities. Their number fluctuated around 0,001 %. The basic physico-chemical characteristics of the obtained biodiesel are described in comparison with international requirements for biofuels. The analyzed product samples obtained from distilled TM, according to mass spectrometry, did not contain harmful impurities bromine, iodine, phosphorus and sulfur-substituted compounds. The total content of chlorine-substituted organic substances in all samples did not exceed 0,07 ± 0,02 %, and N-substituted derivatives did not exceed 0,05 ± 0,01 %, which indicates a rather high ecological purity of bitumen fuel. The main directions of the possible use of the product as liquid fuel for mini-boiler nozzles, as well as for operation in conventional diesel engines, are determined.

The objective of the study was to compare the chemical composition and fatty acid profile in ten clinically healthy bulls of similar weight from eight meat cattle breeds. The animals were raised by extensive grazing under the same geographical conditions. Significant differences were observed between the monitored genotypes in terms of the dry matter content, nitrogenous matter and fats (P ≤ 0.05) in the musculus longissimus thoracis. The concentration of fats ranged from 68.5 ± 18.81 g (Galloway cattle) to 171.6 ± 43.3 g (Aberdeen Angus) per kg of dry matter. The total content of unsaturated fatty acids ranged from 20.0 ± 2.25 g (Aberdeen Angus) to 42.4 ± 7.87 g (Gascon); the total sum of monounsaurated fatty acids ranged from 17.0 ± 2.26 g (Aberdeen Angus) to 33.8 ± 3.61 g (Gascon); and the total sum of polyunsaturated fatty acids ranged from 3.0 ± 1.42 g (Aberdeen Angus) to 5.1 ± 3.99 g (Limousin) per 100 g of fat. The total content of n-6 fatty acids ranged from 2.4 ± 1.28 g (Aberdeen Angus) to 4.2 ± 3.59 g (Limousin) and the total content of n-3 fatty acids from 0.5 ± 0.16 g (Salers) to 1.1 ± 0.04 g (Gascon) per 100 g of fat. The properties we studied may predict the biological, dietetic, and culinary value of the meat.
