Quality parameters and thermogravimetric and oxidative profile of Muruci oil ( Byrsonima crassifolia L.) obtained by supercritical CO2

Abstract

These researches aimed determine the quality parameters, the nutritional profile, and the thermogravimetric and oxidative behavior of Muruci (Byrsonima crassifolia L.) oil obtained by supercritical CO 2 extraction. The results showed an average oil yield of 5.50%. The acidity and peroxide values show good quality and conservation standards, according to the Brazilian legislation. The fatty acid profile indicates a predominance of unsaturated fatty acids with levels above 60%, highlighting the presence of fatty acids omega-6 and omega-9. The thermogravimetric curves showed oil stability at temperatures around 200 °C and exothermic peaks characteristic of mass loss close to 250 °C. The data of oxidative induction time determined by the Rancimat method showed thermal oxidative stability of 20.85 h for the oil obtained. The Fourier transform infrared (FTIR) spectroscopic profile evidenced chemical compounds with predominantly unsaturated structures, confirming its fatty acid profile. Based on the results of the oil analysis, it is possible to recognize the potential of this species in terms of nutritional, functional, and thermo-oxidative stability aspects.

Efeitos do Consumo de Produtos e Subprodutos do Maracujá (Passiflora edulis) nas Doenças Crônicas não Degenerativas

“…Com os avanços no ramo da pesquisa, diversas formas de aplicação da tecnologia em produtos e subprodutos vêm sendo desenvolvidas visando o aproveitamento integral e a aplicação nutricional destes pela aplicação de tecnologias de conversão em matérias-primas aproveitáveis em análise de alimentos. (COSTA, et al, 2016;SANTOS et al, 2018;SANTOS et al, 2019).…”

Utilization of agroindustrial residue from passion fruit (Passiflora edulis) seeds as a source of fatty acids and bioactive substances

“…The latter contribute to the typical yellow color of the fruit and have roles as a functional substance in foods. The passion fruit seeds could be processed as an alternative raw material to obtain a source rich in lipids and essential fatty acids, such as linoleic, oleic and palmitic acids, thus reducing waste from passion fruit processing and generating a new product with prospective health benefits (Acham et al, 2018;Barrales et al, 2015;Claro et al, 2018;Chóez-Guaranda et al, 2017;Ramaiya et al, 2018) Several researches have evaluated the chemical composition and physicochemical behavior of some agroindustry residues by the application of different technological processes to demonstrate its potentiality as a good source of sustainable products (Acham et al, 2018;Claro et al, 2018;Ganesan et al, 2018;Lei et al, 2018;Matos et al, 2019;Oliveira et al, 2016;Satija & Hu, 2018;Santos et al, 2018Santos et al, , 2019.…”

Bioactive Compounds and Evaluation of Antioxidant, Cytotoxic and Cytoprotective Effects of Murici Pulp Extracts (Byrsonima crassifolia) Obtained by Supercritical Extraction in HepG2 Cells Treated with H2O2

“…In the work of Mariutti et al [ 3 ], the major phenolic compounds were quercetin, gallic acid, quercetin hexoside, and quercetin pentoside, where quercetin represented about 66% of total phenolic compounds. Among the unsaturated fatty acids present in murici oil, the main compounds identified were oleic, linoleic, and linolenic acids, which make up about 64% of the lipid profile [ 8 ].…”

“…It is important to note that in recent years, there has been a growth in global interest in the use of clean technologies for the development of food and pharmaceutical products. Therefore, the use of supercritical technology appears as a potential alternative to obtain 100% pure plant extracts, free of solvents, and environmentally “green” [ 10 , 11 , 12 ], where in the scientific literature can be found two works that addressed the extraction of murici pulp by extraction The work developed by Santos et al [ 8 ] addressed the quality parameters and thermogravimetric and oxidative profile of murici oil ( Byrsonima crassifolia L.) obtained by supercritical CO 2 , and the work developed by Pires et al [ 13 ] addresses the determination of process parameters and bioactive properties of the murici pulp ( Byrsonima crassifolia ) extracts obtained by supercritical extraction, the latter being the scientific basis of the present study.…”
