Purpose. To determine the content of fat and fatty acids of total lipids in fat and oil production secondary products: in pressed powder, hydrofuse, bleaching and adsorption clays and deodorization distillate. Methods. In the process of the research, general scientific methods were used: deduction, scientific hypothesis and abstraction. For the laboratory research, the following methods were used: zootechnical analysis, liquid chromatography, spectrophotometry, titrimetry. Methods of variation statistics were used to process the obtained experimental results. Results. Indicators of lipid and fatty acid composition of by-products of fat and oil production were determined. It has been established that wastes of fat and oil production are highly nutritious products: the content of crude fat in pressed powder is 65.45%, in the hydrofuse – 68.11%, bleaching clay – 66.99% and adsorption clays – 27.05%; contains essential fatty acids – linoleic (from 0.52 to 57.77%) and α-linolenic acid (from 0.01 to 0.02%). The total amount of polyunsaturated fatty acids in pressed powder is 57.79%, in the hydrofuse – 51.19%, in bleaching clay – 0.53%, in adsorption clays – 11.6%, and in deodorization distillate – 3.94% of the total amount of acids. Among the group of saturated fatty acids, all these products contain palmitic (from 0.88% to 5.91%), stearic (from 2.80% to 12.01%) and arachidic (from 0.07% to 8.43%) acid. The amount of saturated fatty acids in the pressed powder is 8.66%, in the hydrofuse – 8.87%, in bleaching clays – 9.96%, in adsorption clays – 8.07% and in deodorization distillate – 76.9% of the total acids. Conclusions. Wastes of fat and oil production in their composition contain a significant amount of crude fat, most of the fatty acids are represented by oleic and linoleic acid, which characterizes their quality and biological value as a feed additive for feeding animals and poultry.

Lipid Complex

Microalgae are rich in nutrients and biologically active substances such as proteins, carbohydrates, lipids, vitamins, pigments, phycobiliproteins, among others. The lipid composition of the microalgae Chlorella vulgaris, Arthrospira platensis, and Dunaliella salina was screened for the first time. The proposed method for purifying the lipid complex isolated from microalgae’s biomass involved dissolving the lipid-pigment complex in n-hexane for 4 h and stirring at 500 rpm. We found that the largest number of neutral lipids is contained in the biomass of microalgae Arthrospira platensis, fatty acids, polar lipids (glycerophospholipids), and unsaponifiable substances—in the biomass of microalgae Dunaliella salina, chlorophyll, and other impurities—in the biomass of microalgae Chlorella vulgaris. The developed method of purification of the fatty acid composition of the microalgae lipid complex confirmed the content of fatty acids in microalgae, which are of interest for practical use in the production of biologically active components. We also determined the potential of its use in the development of affordable technology for processing microalgae into valuable food and feed additives.
