Objective: The aim of this study was to determine the methyl esters fatty acids (FAMEs) profile of quinoa seeds (Chenopodium quinoa Willd) of a sample cultivated in Guaranda, Ecuador.Methods: Quinoa oil was obtained from quinoa seeds using the Soxhlet method. FAMEs identification and quantification were carried out using the gas chromatography (GC) with a mass spectrometry (MS), using the database Library NIST14.L to identify the fatty acids present in quinoa oil.Results: Quinoa oil from Ecuador was analyzed by GC-MS, to obtain four majoritarian fatty acids, palmitic acid (10.66%), oleic acid (24.70%), linoleic acid (62.47%), and linolenic acid (2.19%). Omega 6 was the most abundant fatty acid in quinoa oil. Quinoa oil has a good proportion of oleic acid and linoleic acid.Conclusions: Quinoa seeds present a good proportion of fatty acids. These seeds can be used in the food industry for different purposes to enjoy their fatty acids composition. Regular consumption of quinoa can improve health.
Objective: The aim of this study was to identify fatty acids in a sacha inchi oil sample.Methods: Sacha inchi oil was obtained of sacha inchi seeds using the cold pressing method. Fatty acids analysis was carried out using the gas chromatography with a mass selective detector and using the database Library NIST14.L to identify the compounds.Results: Sacha inchi seeds have a high content of unsaturated fatty acids with 34.98% of ɷ6 α-Linoleic and 47.04% of ɷ3 α-Linolenic. Sacha inchi seeds only have 3.98% of palmitic acid.
Conclusions:Sacha inchi seed is a good source of fatty acids ɷ3 and ɷ6, being ɷ3 and ɷ6 in a good proportion. Sacha inchi oil can be used to elaborate functional foods.
Objective: The aim of this study was to determine the composition of methyl esters fatty acids (FAMEs) in yellow pitaya (Hylocereus megalanthus) seeds cultivated in the Palora, Ecuador Amazonian region.Methods: Yellow pitaya oil was obtained from yellow pitaya seeds using the Soxhlet technique. FAMEs identification and quantification were carried out using the gas chromatography (GC) with mass spectrometry (MS) and the database Library NIST14.L to identify the FAMEs present in yellow pitaya oil.Results: Yellow pitaya oil from Ecuador Amazonian region was analyzed by GC-MS, to obtain the five main fatty acids, palmitic acid (11.52%), stearic acid (4.29%), oleic acid (11.09%), vaccenic acid (3.08%), and linoleic acid (69.98%). Omega 6 was the most abundant fatty acid, total content in yellow pitaya seeds oil.Conclusions: Yellow pitaya seeds content a good proportion of polyunsaturated fatty acids (omega 6). For their fatty acid composition, yellow pitaya seeds can be considered as healthy food and can be used in the food industry for different purposes. Regular consumption of yellow pitaya can improve human health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
