Документ Perspective sources of biological active fatty acids and their application in cosmetics technology(2013) Radzievska, Irina; Lazarenko, TatianaWe are conducted the analysis of traditional and exotic vegetable oils with the aim of establishing the potential possibility of their application in cosmetics technology, in particular emulsive nature. Fatty acids contain mustard, coconut, corn, flax, olive, soya-bean, sunflower, palm, rape, apricot stones, amaranth, vine seeds, pumpkin, walnut, coffee, cedar, hemp, sesame, almond, oleum, wheat, ryzhiy are investigated. The fatty acid detection was carried out using gas chromatography manufactured by Hewlett - Packard НР6890 with a flamingly-ionization detector. It was found that palmitic С16: 0 and stearin С18: 0 acids are contained in all investigated oils. Vegetable oils are in the liquid state at a room temperature(all investigated oils after the exception of coconut and palm) contain greater palmitic acid than stearin. Arachic С20:0 and behenic С22:0 fat acids are widely widespread in the nature and contained mainly in vegetable oils, but in small amounts - from 0,16 and 0,14% in flax to 3,05 and 0,80% in coffee accordingly. Fat acids with the odd amount of carbon atoms are not specific for vegetable oils, however margaric acid of С17:0 is 0,04% in hemp oil, The 0,05% in oleum oil, 0,08% in amaranth oil, 0,09% in coffee oil and 0,11% in palm oil. 0,07% of genekozane acid С21:0 and 0,09% of tricozane acid С23:0 are contained in coffee oil. The fizete acid С17:1 is exceptionally in oleum oil in the amount of 1,27%. Monounsaturated fatty acids are most widely widespread with one double connection. In liquid fats they are contained in considerably greater amounts, than the saturated acids and fold 80-90% general fatty acid containing. Vegetable oils mostly contain nonsaturated olein С18:1 9с and elaidic С18:1 9t fatty acids with 18 atoms of carbon and in considerably less linolic acid. Oil from apricot stones and almond contain about 70% of olein acid, in mustard and rape - 58-59%. Linolic C18:2 acid are absent in drupaceous oils - apricot, vine and almond ones. The most linolenic acid of С18:3ω-3 among vegetable oils contains flax oil (55,53%;), γ - linolenic acid is educed in cedar oil (18,81%) and in hemp oil (2,57%).Документ Research of content biologically active components of oils(2013) Lazarenko, Tatiana; Radzievska, Irina; Gromova, ElenaLiposoluble vitamins constitute an important part of vegetable oils. Fats contain liposoluble vitamins A, D, Е, К in the active and nonactive form (as provitamins). Eight connections are known under the name of the vitamin Е: four connections of tocopherol (α, β, γ and δ) and four connections of tocotrienols (α, β, γ and δ). Alpha-tocopherol is the most widespread and biologically active, therefore the vitamin Е is named also alpha-tocopherol or tocopherol. The highest content of tocopherols among the investigated standards is educed in corn oil; soybean oil is a little inferior to her. The least content of tocopherols was fixed in olive oil. In sunflower-seed oil the general concentration of tocopherols does not exceed 95 mgs%, that on 90 % is presented α- tocopherols. In soy-bean, rape and mustard oils in prevailing concentrations contained β -isomer. γ- and δ- isomers at the investigated standards presented in a negligible quantity from 2,4% in mustard press oil to 12,1% in aquated soy-bean. The results can be applied for prognostication of warranty expiration of sunflower date, soy-bean, flax, rape, mustard, corn and olive oils.Документ Research of physical and chemical characteristics of phospholipids’ water solution(2012) Lazarenko, Tatiana; Mank, ValeriyThe electrokinetic potential\potential of phospholipids was determined during the research. Adsorption isotherm of phospholipids that in the surface layer and the possible size of the molecules of phospholipids in the interfacial environment were determined. Впродовж дослідження був визначений електрокінетичний потенційний\дзета-потенціал фосфоліпідів. Були визначені адсорбційна ізотерма фосфоліпідів, що знаходяться в зовнішньому шарі і можливий розмір молекул фосфоліпідів.
