Full textThe dissertation for obtaining the scientific degree of candidate of technical sciences (PhD.) in the specialty 05.18.06 – technology of fats, essential oils and perfumery and cosmetic products. – National Technical University «Kharkov Polytechnic Institute», Ministry of Education and Science of Ukraine, Kharkiv, 2019. The dissertation is devoted to scientific substantiation and development of the technology of protein-fat mixtures of increased nutritional value. The relevance of the research topic is related to the fact that up to now there are practically no domestic specialized products in particular for nutrition of sportsmen. It is known that the most important nutrients for the recovery of the athlete's organism are proteins with a certain ratio of amino acids, polyunsaturated fatty acids (PUFA) -3 groups, vitamins and minerals that are present in insufficient amounts in traditional foods. Therefore, athletes are often forced to take various dietary supplements, which are positioned as sports nutrition, and there is no regulatory framework for these products in Ukraine. Creating the newest protein-fat products on a scientifically based basis will enrich the diet of athletes, which, in turn, will positively affect the full-fledged training and improved athletic performance. Oilseeds are a promising raw material base for these products, which are a concentrated source of nutrients, in particular, essential nutrients. The development of scientifically based technology of protein-fat mixtures of increased nutritional value for sportsmen is a relevant scientific task, which is solved in the dissertation. Relevancy of a subject and significance of dissertation is confirmed by the fact that it has been carried out according to the plan of researches of the Ukrainian research institute of oils and fats (Kharkiv) within the state budgetary research of NAAS of Ukraine: «Development of a protein-fat base for rational nutrition of athletes» (RW № 0117U002374) and «Development of a method for inactivating proteinase inhibitors in a protein-fat base for a balanced nutrition» (RW № 0116U000178), where the applicant was an executive of separate stages of work.. Practical value of work for the oil and fat industry consists in justify the rational ratio of the components of the protein-fat mixture (flax, sesame, sunflower and corn oil) for nutrition of athletes, which is effective for essential amino acids with branched chain (leucine, isoleucine, valine) and tryptophan, the most enriched with PUFA ω-3 groups and plant antioxidants; in determining the technological conditions of its processing by microwave radiation to increase the nutritional value; in substantiation of the recipes of «truffle» cream candies and chocolate paste enriched with protein-fat mixture. The draft technical specification TU U 10.86.1 – 02071180.001:2018 «Protein-fat mixtures from oilseeds» was developed and agreed. Approbation of the production of protein-fat mixture from flax seeds, sesame, sunflower and refined deodorized corn oil, as well as chocolate paste, enriched with protein-fat mixture, was conducted in industrial conditions of Vegetus LLC (Kharkiv). Results of dissertation researches were introduced in educational process of organic synthesis and nanotechnologies department of NTU «КPI» when teaching disciplines «Chemical technologies of food additives and cosmetics», «Development of complex food additives» and «Use of food additives», in course and degree design, as well as in a students research work. For the first time, new scientific data on the composition of fatty acids, sterol fraction, antioxidant complex, amino acid composition and varietal characteristics to the accumulation xenobiotics in oilseeds adapted for cultivation in Ukraine has been obtained; scientifically based composition of protein-fat mixture for special purposes (flax seeds, sesame, sunflower and corn oil), which is effective relative to the content of essential fatty acids, essential amino acids and plant antioxidants; the dependence of the induction period of lipid oxidation of the protein-fat mixture on the content of sesamol, sesamolin, α-linolenic fatty acid and the mass fraction of moisture in the form of approximation models was experimentally determined. The experimental substantiation of the high nutritional value of oilseeds – sunflower, flax, and sesame, – not only as sources of essential fatty acids, but also essential amino acids – leucine, isoleucine, and valine, – received further development; the use of microwave radiation and wetting oilseeds to reduce the activity of inhibitors of proteolytic enzymes and increase the digestibility of the components of the protein-fat mixture were received further development in the thesis. The dried flax, sesame and sunflower seeds were selected as components of the protein-fat mixture. The choice is justified by the fact that the seeds of these oilseeds still do not contain modified genes and can become a source of plant-derived proteins, essential PUFAs, trace elements, as well as a number of valuable compounds necessary for the health of athletes. The overall chemical composition, fatty acid composition, composition of sterol and tocopherol fractions, amino acid, vitamin and mineral composition of flax seeds (Southern Night, Civica, Sympatik), sesame (Ilona, Cadet, Boyarin) and sunflower varieties (confectionery varieties Lakomka, Almaz, Zaporizkyi kondyterskyi), adapted to growing in Ukraine, were investigated Flax seeds are characterized by the highest content of α-linolenic acid. Sesame seed contains antioxidants sesamol and tocopherols. Sesamol is able to enhance the antioxidant effect of tocopherols in oils, so this complex can be offered for use as an antioxidant in fatty products for athletes. In turn, sunflower seeds contain significant amounts of tocopherols. Selected oilseeds also contain phytosterols, which have a number of therapeutic and prophylactic properties, in particular, reduce the level of total cholesterol in the body. Raw materials are rich in amino acids (leucine, isoleucine, valine), which are indispensable materials for building muscle tissue and are involved in the processes of its anabolism and recovery. It is these amino acids in human blood plasma that compete with tryptophan amino acid, which determines the rate of tryptophan penetration into the brain and the decrease in physical activity and efficiency, that is, the occurrence of fatigue. Seeds of oilseeds of selected varieties contain significant amounts of B vitamins and E vitamin. The ability of oilseeds of selected varieties of accumulation of toxic substances, namely heavy metals and nitrates was analyzed. Research results indicate that the amount of salts of heavy metals – copper, zinc, lead and cadmium, – as well as nitrates in all grades is much less than the MPC. As a result of the analysis of the obtained data the following varieties of oilseeds were selected as raw materials for the production of protein-fat mixture: Southern night (flax), Ilona (sesame), Lakomka (sunflower). The composition of protein-fat mixture of increased nutritional value of special purpose was scientifically substantiated: flax seeds – 51.00 ± 2.55 %; sesame seeds – 21.25 ± 1.06 %; sunflower seeds – 12.75 ± 0.63 %, refined deodorized corn oil – 15.00 ± 0.75 %. The fat content in the mixture is 55.92 ± 2.80 %, the protein content was 17.50 ± 0.88 %. The ratio of linoleic and -linolenic fatty acids in the mixture was about 1.2: 1.0; and the essential branched-chain amino acids (leucine: isoleucine: valine) were in the 2.0 : 1.2 : 1.4 ratio. Organoleptic, physico-chemical and technological quality control parameters of the protein-fat mixture were determined. The dependence of the induction period of lipid oxidation of protein-fat mixture in a closed container from storage temperature was calculated. It was established that the induction period of lipid oxidation of protein-fat mixture with the proposed ratio of components was in the range of 175–195 minutes at 85 ± 2 °C, which was about 2.7–3.0 times longer than the induction period of flaxseed component and about 1.3–1.4 times – the induction period of sunflower seeds. The oxidative stability of the protein-fat mixture was ensured by the fact that components, which were used in its manufacture, had not been subjected to prolonged heat treatment. But the presence of proteolytic enzymes inhibitors in the composition of oil seeds reduces the digestion of protein by the body and significantly limits its use in the food industry. In this regard, a technological solution to reduce the activity of proteolytic enzymes inhibitors of oilseeds of protein-fat mixture to maximize its nutritional value has been developed. This solution consists in its wetting and processing by microwave radiation ( = 2450 MHz). Rational conditions of oilseeds processing (hydration to 11–13 % moisture content and 210–260 s microwave radiation processing time) were experimentally established. These conditions will increase the biological value of the mixture, namely, increase the degree of cleavage and digestibility of proteins in the gastrointestinal tract. The technological scheme for the production of a protein-fat mixture of increased nutritional value based on oilseeds was proposed, a draft technical specification TU U 10.86.1 – 02071180.001:2018 for protein-oil mixtures from oilseeds was developed and agreed upon. Recipes of fat-containing confectionery – cream candy mass for the production of truffle-type sweets and chocolate paste with the addition of 15 % protein-fat mixture of high nutritional value were scientifically substantiated. It was experimentally proved that the induction periods of the candy mass and chocolate paste of the proposed composition exceed the control values by 44 and 55 %, respectively. The organoleptic evaluation of test samples was carried out to determine the effect of protein-fat mixture on consumer properties of confectionery products. Based on its results it was determined that the use of protein-fat mixture in cream candy masses and chocolate paste influenced on such organoleptic indicators like taste and aroma that were higher than in control samples. In particular, there were a characteristic savory nutty aroma and taste, longer remains «mouth-feeling»in the prototypes of confectionery products. A further increase in the content of the mixture – more than 15 % – leaded to the appearance of a mealy taste and characteristic aroma of flaxseed. The effective concentration of the protein-fat mixture in the confectionery products was chosen at the level of 15 % based on the results of the organoleptic assessment The results of determining the physico-chemical quality control parameters of confectionery indicated that when 15% of the protein-fat mixture was added to a creamy candy mass and chocolate paste, the change in the mass fraction of moisture and the mass fraction of fat occurred within the framework of normalized values. Reducing the total sugar content did not affect the organoleptic properties of confectionery, but reduced the cost of production. The developed products have a higher content of essential amino acids compared to the control, their lipid composition changes – the content of PUFAs of the ω-3 group increases significantly. As part of the developed confectionery products, there is also a significant amount of dietary fiber – a nutrient that accelerates the feeling of fullness, as well as a factor in the formation of normal intestinal microflora and the obesity prevention.

Mounayar, Rana. "Oral fat sensitivity in humans : links with salivary composition." Thesis, Dijon, 2013. http://www.theses.fr/2013DIJOS074.
Full textHuman fat perception has recently triggered particular interest as it was shown that it does not only involve aroma and texture perception but also taste perception. The latter was supported by the presence of free fatty acids (FFA) taste receptors on the tongue. Recent studies have shown that fat taste sensitivity is variable among individuals. This inter-individual variation could be linked to genetic or environmental factors. However, saliva could also play a role in this perception. The role of saliva in taste perception is increasingly recognized. Saliva contains molecules able of interacting with fat such as lipase and lipocalin. It is also a complex fluid which contains a large diversity of proteins and metabolites. Its regulation is also complex and its composition may vary after a sensory stimulation. Indeed, studies have shown that when giving primary taste stimulations, the whole salivary proteome is modified. Thus, the first aim of the present work was to use both targeted (enzymatic activity, antioxidant capacity etc) and untargeted approaches (proteomics and metabolomics) to identify links between taste sensitivity to a fatty acid, oleic acid, and the salivary composition. The second aim was to investigate whether the salivary composition is modified after an oral stimulation by oleic acid.Two groups of thirteen male subjects (highly and weakly sensitive to the taste of oleic acid) were selected from an initial panel of 73 healthy participants. Their whole saliva was collected in two ways; the first without stimulation in order to study the links between oral sensitivity to oleic acid and saliva composition and the second using a stimulation by the same fatty acid in order to study potential modifications of saliva composition depending on sensitivity. Results show that salivary composition is linked to oral fatty acid perception. Markers previously reported as associated to taste perception were determined in the highly sensitive group (carbonic anhydrase, Zinc Alpha 2 glycoprotein and cystatins) while markers (organic acids) indicating a higher bacterial load were identified in weakly sensitive group. Furthermore, results obtained after stimulation by oleic acid suggest that saliva composition is modified, which confirms its dynamic nature. As different modifications were observed for the highly and weakly sensitive group, our results suggest that saliva is not only modified after a stimulation but also depending on the sensitivity to that particular stimulation

Full textA biobased photohealing coating has been developed from 4 components, including epoxidized linseed oil and 4,4’- diphenyldiamine disulfide. The process has been carried out in two steps via an epoxy/amine reaction. The photohealing character is ensured by the presence of disulfide bridges which, under UV irradiation, can be photolyzed reversibly. The obtained coating contains about 46 wt-% of biobased compounds and 24 wt-% of photosensitive molecules. Compared to an analogous material without disulfide bond, the coating exhibits a lower crosslinking density and a higher fracture elongation.A significant repair of a 100 μm depth scratch has been occurred. An increase of 42% of tensile strength has been observed in only 3 hours of UV irradiation at 100°C

Full textTriacylglycerols (TAG) are an essential energy storage in many cells. Their composition is diverse; they are the main component of the seed oil for the food industry or used to produce industrial compounds. Acyl-CoA: diacylglycerol acyltransferase (DGAT) catalyze the final and rate-limiting step of TAG synthesis by transferring a fatty acid onto a diacylglycerol. In plants, there are three families, DGAT1, DGAT2 and DGAT3, sharing no homology and of unknown structure. It prevents any improvement of seed oil yield and quality by a rational approach. DGAT1 involvement in edible oil accumulation was demonstrated. In some plants, DGAT2 plays a key role in the synthesis of unusual TAG such as hydroxylated TAG found in castor oil and used to produce lubricants and bioplastics. DGAT3 contribution to TAG biosynthesis has not been demonstrated in planta. We studied three families of DGAT from the model plant Arabidopsis thaliana, belonging to the same family as oilseed rape, and a DGAT1 from oil palm, an industrial crop. DGAT expression in bacteria, yeasts and the study of mutant plant lines allowed us to characterize their activities. The modulation of yeast TAG content and composition induced by DGAT expression demonstrated the value of these enzymes for the production of tailored microbial oils
