Korean Maize Hybrids Present Significant Diversity in Fatty Acid Composition: An Investigation to Identify PUFA-Rich Hybrids for a Healthy Diet.
Ontology highlight
ABSTRACT: Precise information on the content and composition of nutritionally essential metabolites in food crops is a prerequisite for dietary recommendations and nutrient-dense food formulations. In the present study, the fatty acid profile of 21 Korean maize hybrids was analyzed by gas chromatography (GC)-mass spectrometry (MS). In the studied hybrids, linoleic acid (LA; C18:2n6c) was dominant (38.0-58.9%), followed by oleic (OA; C18:1n9c) (23.5-45.3%), palmitic (C16:0) (10.8-17.3%), and stearic acids (C18:0) (1.84-3.86%). Among all the quantified fatty acids, the highest variation was recorded for LA and OA. The highest amount of LA (58.9%), the lowest amount of OA (23.5%), and the highest polyunsaturated fatty acids (PUFAs)/monounsaturated fatty acids (MUFAs) ratio of 2.47 were recorded in the Shingwang hybrid. The highest PUFAs/saturated fatty acids (SFAs) ratio of 4.04 was recorded in the Ahndaok hybrid due to the high content of LA (57.8%) and low amount of SFA. Similarly, the highest PUFAs + MUFAs/SFAs ratio of 6.38 was recorded in the Pyeonggangok hybrid as a result of the high OA (34.6%) and LA (51.4%) contents, along with the lowest amount of SFAs. Considering the high levels of health-beneficial MUFAs and PUFAs and low levels of undesirable SFAs, the maize hybrids Pyeonggangok, Ahndaok, and Shingwang can be used in the preparation of a healthy PUFA-rich diet.
