Data on fatty acid profiles of oils isolated from the mesocarps and seeds of four avocado species derived from Sabah, Malaysia

This dataset presents detailed fatty acid composition data from the mesocarp and seed of four avocado varieties cultivated in Sabah, Malaysia. Avocado is a sought-after superfood, largely due to its high content of health-benefiting unsaturated fatty acids. While varieties like Hass and Fuerte have been well studied, no reports exist on the lipid profiles of avocados grown in Sabah-a region increasingly active in avocado farming. This study addresses that gap by analyzing the fatty acid profiles of four Sabah-derived varieties: Quoin Avocado 1 (QAV1), Quoin Avocado 2 (QAV2), Short Neck Russell, and Local Bacon, with Australian Hass as a reference. A total of 45 mesocarp and 25 seed samples were collected from fruits grown in the Keningau area. The samples were freeze-dried, and total fats were extracted following AOAC guidelines. The extracted lipids were converted to fatty acid methyl esters (FAMEs) and analyzed using Gas Chromatography-Flame Ionization Detection (GC-FID). The fatty acids were classified into saturated (SFA), monounsaturated (MUFA), and polyunsaturated (PUFA) categories for comparative evaluation. The dataset includes a comprehensive profile of 37 FAMEs, enabling in-depth comparisons between the local varieties and the commercial Hass avocado. The findings offer valuable insights into the nutritional value, genetic diversity, and potential commercial applications of Sabah avocados, contributing to future avocado breeding efforts and regional agronomic development.
