“…Important factor influencing on the course of the isomerization was also a kind of solvent. Kapoor and coworkers studied the influence of solvents that may be applied to the alkali isomerization. Glycerol and ethylene glycol were indicated as the best solvents for this type of reactions.…”

The process of acidolysis of egg yolk phosphatidylcholine (PC) with concentrates of conjugated linoleic acid (CLA) was performed. CLA was obtained by the alkali isomerization of sunflower and safflower oils. Analysis of the influence of different reaction conditions on the process of isomerization was investigated. Reactions were carried out in preparative scale at 150°C in the ethylene glycol and afforded the mixture of isomers: cis-9,trans-11 and trans-10,cis-12. Their content was 30.8 and 32.3% for product obtained from sunflower oil and 30.4 and 36.4% for the product obtained from safflower oil. Crude concentrates were purified by urea complexation with 1:3 fatty acids to urea weight ratio. Enzymatic modification of phosphatidylcholine from egg yolk with CLA concentrates was carried out using lipase from Rhizomucor miehei. The process was performed at 45°C with controlled water activity. The highest effective incorporation (42%) of CLA into PC and lysophosphatidylcholine molecules was obtained using concentrate from the sunflower and safflower oils after 36 h of reaction.Practical applications: Results of this research are useful for the development of scaled up acidolysis reaction to produce phosphatidylcholine enriched in biologically active isomers of CLA using the sunflower or safflower oil as a rich source of linolenic acid.

Better sources of drying oils for coatings and conjugated linoleic acid (CLA) for potential health benefits are of continuing interest. Iodine under photochemical conditions in hexanesB at reflux temperatures was investigated as a catalyst for conjugating soybean oil (SBO) for use as drying oils and as a potential source of CLA. Variations in catalyst loading, SBO, light source, free radical catalyst, solvent and temperature strongly affected the efficiency of the process. Changes in fatty acid isomer distributions in conjugated SBO (CSBO) influenced drying properties of CSBO. Conjugated dienes formed were predominantly trans‐9,trans‐11, which contrasts distributions found with catalysts such as strong base and metal compounds. Drying times of some of the CSBOs were superior to that of raw linseed oil. Iodine was partially recovered.

Yarrowia lipolytica is known to have the ability to assimilate hydrophobic substrates like triglycerides, fats, and oils, and to produce single-cell oils, lipases, and organic acids. The aim of the present study was to investigate the effects of different oil sources (borage, canola, sesame, Echium, and trout oils) and oil industry residues (olive pomace oil, hazelnut oil press cake, and sunflower seed oil cake) on the growth, lipid accumulation, and lipase and citric acid production by Y. lipolytica YB 423-12. The maximum biomass and lipid accumulation were observed with linseed oil. Among the tested oil sources and oil industry residues, hazelnut oil press cake was the best medium for lipase production. The Y. lipolytica YB 423-12 strain produced 12.32 ± 1.54 U/mL (lipase activity) of lipase on hazelnut oil press cake medium supplemented with glucose. The best substrate for citric acid production was found to be borage oil, with an output of 5.34 ± 0.94 g/L. The biotechnological production of valuable metabolites such as single-cell oil, lipase, and citric acid could be achieved by using these wastes and low-cost substrates with this strain. Furthermore, the cost of the bio-process could also be significantly reduced by the utilization of various low-cost raw materials, residues, wastes, and renewable resources as substrates for this yeast.
