Buriti of the cerrado of Minas Gerais, Brazil: physical and chemical characterization and content of carotenoids and vitamins

Abstract

The fruit species of the Brazilian Cerrado, such as buriti (Mauritia vinifera), occupy a prominent position in the ecosystem since they contribute to the economic potential of the region and have high nutritional value. We aimed to evaluate the physical characteristics, chemical composition and content of vitamin C, carotenoids, vitamin E and folates in pulp of buriti from the Brazilian Cerrado of Minas Gerais, Brazil. The length, diameter, mass and fruit yield were evaluated. The titratable acidity was determined by volumetric neutralization; pH by potentiometry; soluble solids by refractometry; moisture using an oven; ash using a muffle furnace; proteins by the micro-Kjeldhal method; total dietary fiber by the gravimetric non-enzymatic method and lipids with a Soxhlet extractor. Vitamin C and carotenoids were analyzed by high performance liquid chromatography with detection by diode array (HPLC-DAD) and vitamin E and folates by HPLC with fluorescence detection. Buriti pulp showed 12.13 g.100g -1 of lipids and 74.86 g.100g -1 of moisture. Also, the fruit showed high content of dietary fiber, carotenoids, vitamin C, vitamin E and folates. Buriti can contribute to the adequate intake of fiber and vitamins and to preventing the incidence of disorders, especially those more frequent in native populations of the Cerrado.Keywords: Mauritia vinifera; vitamin C; vitamin E; folates; HPLC.Practical Application: Buriti can contribute to the adequacy of intake of fiber and vitamins and prevent several disorders.

Characterization of Buritirana (Mauritiella armata) Fruits from the Brazilian Cerrado: Biometric and Physicochemical Attributes, Chemical Composition and Antioxidant and Antibacterial Potential

“…The whole fruit had a mass of 10.07 g ( Table 1 ). The buritirana fruit showed a lower mass in comparison with buriti ( Mauritia vinífera ) [ 29 ], which presented a WS fraction of 60.43 g, PU of 13.55 g, PE of 15.68 g and SE of 31.19 g. Moreover, the buritirana seed ( Table 1 ) presented the highest mass, followed by the peel and pulp (6.46 g > 1.94 g > 1.67 g), representing 64.15%, 19.27% and 16.58% of the fruit, respectively. These values were higher than those of buriti pulp ( Mauritia flexuosa ) grown in Goiás and Pará (16.43% and 8.53%, respectively) [ 30 ].…”

Improvement of sensorial and technological characteristics of chocolate cakes with buriti fruit by‐product

“…Differently, Martínez‐Cervera et al (2011) observed higher lightness of crust and crumb (38.30 to 39.60) in chocolate muffins, in addition to redness (5.90–6.50) and yellowness (5.60–6.00) slightly lower than the results of the present study. The discrepancies in color coordinates may be occurred due to the lower proportion of cocoa and wheat flour in the study by Martínez‐Cervera et al (2011), in addition to the lack of PDBB, which is brown with red and orange nuances resulting from the high carotenoid content in buriti fruit (Hamacek et al, 2018).…”

“…Manhães and Sabaa-Srur (2011) detected a high content of iron, copper, chromium, magnesium, selenium, and iodine in the fruit pulp. Other studies found the presence of pectin, α-and β-carotenes, vitamin C, tocotrienols, tocopherols, folates, and phenolic compounds (Hamacek et al, 2018;Leite et al, 2021;Schiassi et al, 2018).…”

Avaliação físico-química e capacidade antioxidante do extrato de buriti (Mauritia flexuosa L.) e atividade antitumoral em linhagem celular de câncer de mama MDA-MB-231

“…A viabilidade celular foi determinada por ensaio de redução de MTT (adaptado de MOSMANN, 1983 SANDRI et al, 2017;HAMACEK et al, 2018;SCHIASSI et al, 2018;BERNI et al, 2019;NASCIMENTO-SILVA et al, 2020). Os teores de lipídeos e carboidratos mostraram-se na faixa descrita pelos demais estudos oscilando, respectivamente, entre 6,20 e 22,20; e 2,10 a 26,20 g / 100g, respectivamente.…”

“…Os teores de carotenoides totais e -caroteno da polpa de buriti foram, respectivamente, 370,00 µg / g e 305,00 µg / g. Estes teores de carotenoides totais e de -caroteno encontraram-se dentro da faixa de valores descritos na literatura (233,60 µg / g a 589,00 µg / g e 137,10 µg / g a 372,30 µg / g, respectivamente) para amostras de buriti de diferentes regiões (DE ROSSO & MERCADANTE, 2007;RODRIGUEZ-AMAYA;AMAYA-FARFAN, 2008;MANHÃES & SABAA-SRUR, 2011;CÂNDIDO et al, 2015;SANTOS et al, 2015;ROMERO et al, 2015, HAMACEK et al, 2018PEREIRA-FREIRE et al, 2018).…”
