Polyphenolic Content

Plants of the genus Agrimonia L. perfectly fit the current trends in nutrition and food technology, namely, the need for raw materials with a high content of bioactive natural compounds, including polyphenols, which could be added to food. The composition of polyphenolics, including agrimoniin and flavonoids, in the aerial parts of Agrimonia procera Wallr. (A. procera) and Agrimonia eupatoria L. (A. eupatoria) (Rosaceae) was determined using HPLC-DAD-MS. The polyphenolic content of A. procera was found to be 3.9%, 3.2%, 2.9%, 1.8% and 1.1%, and that of A. eupatoria was determined to be 1.3%, 0.3%, 0.9%, 0.6% and 0.5% in the dry matter of leaves, stems, fruits, seeds and hypanthia, respectively. Except for A. procera hypanthia, agrimoniin was the main polyphenolic compound in the aerial parts of the studied Agrimonia species. Both plants are also a valuable source of flavonoid glycosides, especially apigenin, luteolin and quercetin. The obtained data indicate that both A. procera and A. eupatoria are potentially good sources of polyphenols (albeit significantly different in terms of their qualitative and quantitative composition), and may not only be a medicinal raw material, but also a valuable material for food use such as nutraceuticals or functional food ingredients.

The aim of this study was to evaluate the effect of 6-benzylaminopurine (BAP) separately and in interaction with auxins on the change in the qualitative and quantitative composition of flavonoids in the raw materials of regenerating plants Iris sibirica L. Cambridge grade in comparison with aeroponic and intact raw materials using the method of high-performance liquid chromatography. Raw materials of I. sibirica Cambridge variety obtained in vitro culture had a richer qualitative composition of flavonoids than intact plants. The dependence of the accumulation of flavonoids on the concentration of 6-benzylaminopurine in nutrient media was noted. The presence of 13 compounds was observed in extracts of 70% ethyl alcohol from regenerating plants grown at the lowest concentration of BAP (1.0 µM) within the experiment. In quantitative terms, the flavonoid apigenin was maximally determined on a medium with BAP 1 µM, and kaempferol - on media with BAP 5.0 µM, supplemented with auxins. For a medium with 7.5 µM BAP, the lowest variety of compounds was observed (9) and the lowest kaempferol content. Auxins influenced the synthesis of flavonoids. The amount of flavonoids in all variants of the experiment increased by an average of 13% in the presence of auxins. The stages of the technological process of obtaining raw materials I. sibirica Cambridge variety on the basis of clonal micropropagation and cultivation in aeroponics conditions allowed to obtain raw materials that do not contain heavy and toxic metals, are not infected with pathogens and pests. With 1 m2 of useful area of aeroponics for 1 year, it is possible to collect 5 times more raw materials than with field cultivation. According to the qualitative composition of phenolic compounds, aeroponic raw materials are identical to intact plants.

The paper presents the methodology of preparation of samples of oilseeds, lettuce, apples for research by chromatographic control of xenobiotics of the following chemical groups of pesticides: benzimidazole derivatives, anilinopyrimidine derivatives, bipyridylium derivatives. The implementation of the following processes is considered: homogenization of the sample, purification of the extract by solid-phase or liquid-liquid extraction, obtaining a plant extract, obtaining an extract of analytes. For fine-grained homogenized samples of sunflower seeds, the optimal ratio of raw material -extragent is 1:20, for pasty homogenized samples of apple fruit - 1:10, for liquid samples of homogenized lettuce - 1: 5. Analysis of the distribution of xenobiotics in the system octane/water, the dipole moment of solvents allowed to determine the extractants that are able to dissolve and remove xenobiotics from raw materials. It was found that a mixture of acetonitrile and methanol (4: 1) should be used to remove benzimidazole derivatives and anilinopyrimidine derivatives, bipyridylium derivatives are best extracted with methanolic trifluoroacetic acid (9.5: 0.5). Quantitative analysis of xenobiotics content in extracts obtained from samples artificially enriched with xenobiotics was performed. The most complete xenobiotics were removed from samples of plant products containing traces of fat. The most difficult process of sample preparation is the process of obtaining sunflower seed extract. The content of xenobiotics in extracts obtained from samples artificially enriched in analytes is influenced by the temperature at which the process takes place and the duration of extraction. Based on the chemical composition of the sample matrix and the list of analytes, the conditions of the variable component of the methodology are proposed: obtaining plant extract under the action of selective solvents, homogenized raw material-solvent with constant stirring of the extraction system at 180-200 rpm, or under the action of ultrasonic vibrations with a frequency of 37 kHz from 4°C to 25°C for 5-25 minutes. The control of the qualitative and quantitative composition of the studied plant extracts and analyte extracts was investigated by the methods of high-performance liquid and gas chromatography (liquid and gas) with mass-selective detectors.

The article deals with the problems of mineral raw material losses of quality and quantity management in developing of large-scale complex-structure and composition deposits of solid minerals. It is shown that a very high degree of mining and geological conditions variability in time and space for the development of mining units is typical for such deposits. This significantly complicates the qualitative and quantitative operating losses setting and accounting of mineral raw materials during its extraction in the framework of existing general and industry regulatory documents. Conceptual principles for face-by-face operational setting of losses and impoverishment of minerals for the conditions of bulk mining of complex-structure deposits with the formation of gross mining flow with economically feasible and specified level of quality (the content of commercial and harmful components) are stated. These principles generally do not contradict effective instructions main provisions and are made to minimize the total operating losses during the processing of several mine sections (faces).

Balsamic Vinegar

Vinegar is one of the oldest fermented products in the world and its production dates back to around 2000 BC. It is a liquid fermentation product that consists from 4% to 9% acetic acid, which is commonly used and consumed globally, either directly or as a condiment in food. It is produced by two-stage fermentation systems, i.e., the alcoholic fermentation of sugary substrates and subsequently, the acetous fermentation (oxidation) of the ethanol into acetic acid. There are numerous different types of vinegars produced worldwide based on the raw material and the production method used. Among all the vinegars available, the most common types of vinegar, produced in different parts of the world, and including some top-quality famous products, are “cider vinegar,” “balsamic vinegar,” “wine vinegar,” “rice vinegar,” and “malt vinegar.” Tropical fruit vinegars and vinegars made from any kind of agricultural surpluses are also available. The different raw materials and the methods used for the production of the different types of vinegars lead to a variety of products with distinctive characteristics. In this paper, definitions, local market and legislation and current trends in vinegar production are briefly highlighted and discussed.

Technologies for obtaining expanded tobacco have been developed, which make it possible to increase the volume of tobacco leaves up to 50% and reduce the consumption of tobacco raw materials in the manufacture of smoking articles by up to 30%. However, they have a number of disadvantages, the main one being a decrease in the tasting evaluation of raw materials. The subject of the research is to determine the effect of microwave radiation when processing freshly harvested tobacco leaves on improving the qualitative and quantitative indicators of tobacco raw materials. The object of the research is freshly harvested leaves of three botanical varieties of tobacco grown at the experimental site of the Federal State Budgetary Scientific Institution «All-Russian Research Institute of tobacco, makhorka and tobacco products», harvested in the condition of technical maturity. The purpose of the research is to study the effect of microwave- radiation treatment of tobacco leaves during their post-harvest processing on the possibility of obtaining expanded tobacco and on the qualitative and quantitative composition of raw tobacco. The following has been established: the obtained raw tobacco in terms of dimensional characteristics is similar to expanded tobacco obtained under factory conditions; carbohydrate-protein ratio (Shmuk’s number) in comparison with the control on has increased 2,5–4,5 times, and the nicotine content has decreased 1,3–1,4 times; the conventional consumption of raw tobacco for the manufacture of cigarettes is reduced by 8 ... 17% in comparison with the control one, depending on the drying technology. The results of the studies have revealed the positive effect of microwave radiation when processing freshly harvested tobacco leaves on the improvement of the qualitative and quantitative indicators of raw tobacco.

The effectiveness of an amine-negative starter culture (Lactobacillus sakei CTC494) in the reduction of biogenic amine production during the ripening of fermented sausages was examined. Four batches were manufactured in parallel:spontaneously fermented and starter-mediated sausages were manufactured from two lots of raw materials of different hygienic quality. Besides the biogenic amine contents, changes in the microbial counts, nitrogenous fractions, pH, and water content were measured at several sampling points during the ripening process. In sausages manufactured from good quality meat, the starter strain of L. sakei reduced and even inhibited biogenic amine accumulation during sausage fermentation, the end products showing extremely low biogenic amine contents (tyramine levels less than 15 mg/kg of dry matter and putrescine and cadaverine levels less than 5 mg/kg of dry matter). Nevertheless, starter-mediated sausages made from poorer-quality raw materials showed much higher amine contents (308, 223, and 36 mg/kg of dry matter of cadaverine, tyramine, and putrescine, respectively), which were only slightly lower than those of the spontaneously fermented sausages made from the same raw materials. The relatively high bacterial numbers of raw materials of poorer-hygienic quality diminished the beneficial effect of the starter strain. Therefore, the effectiveness of the starter was strongly dependent on the hygienic quality of the raw materials used.
