Abstract
Germination is a promising technique for enhancing the nutritional and functional properties of seeds. Among the nuts, peanuts are composed of approximately 50% oil, which is abundant in unsaturated fatty acids, tocopherols, and phytosterols. This study investigated the changes in phytochemical profile, antioxidant capacity, and oxidative stability of oil from germinated peanuts. Peanuts were germinated over 0, 2, 4, 6, and 8 days. The oil from germinated peanuts exhibited increased levels of α-tocopherol, phytosterols, and carotenoids, while the γ-tocopherol, oleic acid, and linoleic acid levels were reduced. Notably, the oil from germinated peanuts at Day 8 exhibited substantially improved antioxidant activity and oxidative stability compared with oil from ungerminated peanuts. These enhancements were attributed to the elevated phytochemical content of the peanut oil resulting from germination. These results highlight that germination of peanut seeds is an effective strategy for enhancing peanut oil's phytochemical content and oxidative stability, thereby presenting potential benefits for health-conscious consumers.
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.
