Development of symmetric monounsaturated triacylglycerols by Rhodosporidium toruloides cell factory for cocoa butter equivalent
In the present study, various factors including carbon source, nitrogen source, Mg2+, and pH value were investigated to determine the optimal conditions for producing cocoa butter equivalent using R. toruloides. The maximum of biomass, lipid content, and lipid production were achieved at levels of 7.8 g/L, 61.0%, and 4.4 g/L, respectively. The oil from R. toruloides mainly consisted of 16:0, 18:0, and 18:1 with 18:1 dominating at the sn-2 position, which was further confirmed by 13C NMR analysis. UPLC-MS analysis showed that the sum of sn-POP, sn-POS, and sn-SOS accounted for up to 27.11% in the triacylglycerol species of the oil produced, which allows those triacylglycerols to be further separated and isolated from other triacylglycerols and used for cocoa butter equivalent. Notably, the production of cocoa butter equivalent reached 1.13 g/L, demonstrating the scientific feasibility of producing CBE through fermentation. These findings indicate a promising future for the fermentation-based production of cocoa butter equivalent.
期刊介绍：
The Journal of the American Oil Chemists’ Society (JAOCS) is an international peer-reviewed journal that publishes significant original scientific research and technological advances on fats, oils, oilseed proteins, and related materials through original research articles, invited reviews, short communications, and letters to the editor. We seek to publish reports that will significantly advance scientific understanding through hypothesis driven research, innovations, and important new information pertaining to analysis, properties, processing, products, and applications of these food and industrial resources. Breakthroughs in food science and technology, biotechnology (including genomics, biomechanisms, biocatalysis and bioprocessing), and industrial products and applications are particularly appropriate.
JAOCS also considers reports on the lipid composition of new, unique, and traditional sources of lipids that definitively address a research hypothesis and advances scientific understanding. However, the genus and species of the source must be verified by appropriate means of classification. In addition, the GPS location of the harvested materials and seed or vegetative samples should be deposited in an accredited germplasm repository. Compositional data suitable for Original Research Articles must embody replicated estimate of tissue constituents, such as oil, protein, carbohydrate, fatty acid, phospholipid, tocopherol, sterol, and carotenoid compositions. Other components unique to the specific plant or animal source may be reported. Furthermore, lipid composition papers should incorporate elements of yeartoyear, environmental, and/ or cultivar variations through use of appropriate statistical analyses.
