Avaliação do teor de lipídeos em resíduos de frutas regionais e seu uso como matéria-prima para a indústria de cosméticos

Abstract

Brazil's biodiversity is extensive, containing approximately 12% of all life on the planet. This wealth is mainly due to the Amazon region, where a large part of the species that exist in Brazil are found, including palm trees, which are quite diverse and used by the population, however, their seeds/pits are generally not used, discarding them. As garbage, given this, this work aims to evaluate the oil from almonds from the peach palm fruit, carry out a bibliographical research on the oil from the tucumã almond, characterize the lipids they contain and where they can be used in the cosmetic industry, and thus, generate ecological, economic and social benefits for the population. Almond oils were extracted using the modified Bligh-Dyer method and were analyzed using a gas chromatograph coupled to a mass spectrometer (GC-MS) to identify the lipids present, after which theoretical bases were taken to verify their applications in industries. The peach palm almond oil, with a percentage content of 10.42% in 50.0g of the sample, proved to be rich in lauric acid (59.34%), which in comparison with almond oils from other fruits proved to be in a higher concentration, followed by myristic acid (21.93%) and oleic acid (8.30%), tucumã almond oil, according to bibliographical research, has very similar properties to peach palm, which is quite interesting, since the acids they contain can be widely applied in the cosmetic industries, thus ensuring that waste has a more sustainable and profitable destination.
