Abstract
Vegetables including asparagus contain a wide range of fatty acids, mainly stored in triacylglycerols. One class of interesting minor fatty acids is the family of furan fatty acids (FuFAs) because of their antioxidant properties. Since FuFAs have not been studied previously in asparagus (Asparagus officinalis L.), we developed and applied a simplified method for their analysis in 20 fresh and three preserved samples. Four FuFAs were detected with clear dominance of the dimethyl-substituted FuFAs (D-FuFAs) 11D5 and 9D5 as well as small amounts of the monomethyl-substituted FuFAs (M-FuFAs) 11M5 and 9M5. The total amounts of FuFAs in fresh white asparagus ranged from 1.4 to 4.6 mg/100 g dry weight (mean 3.0 mg/100 g dry weight). Subsequent LC-Q-Orbitrap-HRMS measurements enabled the detection of 22 different FuFA-containing TAGs. These were predominantly found together with one or two polyunsaturated fatty acid.
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.
