%X The present study was carried out to investigate the proximate composition, fatty acid (FA) profile and volatile compounds (VC) of cooked green licuri (Syagrus coronata) - an unripe stage that is then cooked - and naturally ripe licuri almonds. The FA profiles were determined by gas chromatography (GC) and the VC composition was evaluated using headspace-solid-phase microextraction coupled with GC-MS. The cooked green licuri presented higher moisture, and lower contents of ashes, proteins and lipids than naturally ripe licuri almonds. The FA profiles of cooked green licuri and naturally ripe licuri almonds showed that saturated FAs were predominant (80%) in both samples, and the concentrations of lauric, palmitic, and oleic acids in naturally ripe licuri almonds were higher than those in cooked green licuri. Limonene was the predominant compound in naturally ripe licuri almonds. The main class of VC in the cooked green licuri were aldehydes, with 3-methyl-butanal and furfural being the main species. Alcohols, such as 3-methyl-butanol and 2-heptanol, were the main class of VC in naturally ripe licuri almonds. Among the volatile compounds, 1-hexanol and 2-nonanone contributed to the aroma of cooked green licuri almonds, whereas 2-heptanone, ethanol, and limonene contributed to the aroma of naturally ripe licuri almonds (almonds not subjected to any cooking process). In a word, cooked green licuri and naturally riped licuri almonds, despite having different proximate compositions, present similar fatty acid profile and distinct aromatic characteristics. Therefore, cooked green licuri and naturally riped licuri almonds are an alternative source of nutrient and could be investigated for the use in the food industry to enhance flavor and aroma to new products.
