Tag hinzufügen | Zusammenfassung: | The mamey (Pouteria sapota) is native to Central America, and this tree is significant due to the versatility offered by its fruits, seeds, and wood. The oil contained in the seeds has limited industrial application, resulting in underutilization of these seeds and consequently diminishing the value of the fruit. The objective was to extract mamey seed oil (Pouteria sapota) using supercritical fluid and cold pressing methods for the production of an agro-industrial product. A literature review was conducted on the study matrix, extraction methods, matrix characterization, and lipid profile. The mamey fruits were obtained from Los Rios. An experimental design was applied, in a 2 (22), with the response variables being relative density, acidity, pH, saponification index, refractive index, and yield. The cold pressing method has a superior yield of 56.42%, compared to the supercritical extraction method, where the yield is 5.41%. Regarding the quality of the oil, better results are evidenced with the supercritical fluid extraction method, where the relative density is 0.919; acidity is 0.36%; pH is 4.21; saponification index is 134.47 mg/g; and refractive index is 1.468. The lipid profile of mamey oil by gas chromatography indicates the composition of fatty acids present in the oil, with a higher presence of palmitic acid, methyl ester (13.03%), stearic acid, methyl ester (30.24%), oleic acid, methyl ester (40.94%), linoleic acid, methyl ester (7.62%), and phthalic acid, bis(6-methylheptyl) ester (6.08%). It is concluded that mamey oil exhibits a diversity of fatty acids that make it versatile for cosmetic applications such as facial serum, which resulted in a pH of 5. |
