“…Considering the results on a dry basis (Table 4), the antioxidant capacity as determined by the DPPH• method for the three regions studied, was greater than that reported by Cândido et al, (2015) for buriti pulp from the Savanna of 123.28 µmol of TE/g and of 20 µmol of TE/g by (Gonçalves et al, 2010), and for exotic fruits such as camu-camu (141 µmol of TE/g) and cambuci (9.0 µmol of TE/g) (Genovese et al, 2008).…”

Highlights: The present work emphasizes the importance of knowledge of the proximal composition and the bioactive compounds of buriti pulp and its sweet obtained from different locations of Brazil, aiming at the valorization of the native fruit. This article is the first to report the concentration of bioactive compounds in buriti sweet and one of the few to describe their nutritional value. The paper should be of interest to readers in the of area "assessment of the nutritional quality of fruit products".

“…e results obtained in this investigation are superior (<17.12) to those reported by Silva and Sirasa [59] whose values are 12.6 mg EAA/100 gFW in frozen soursop pulp. e difference between vitamin C values may be associated with factors such as storage temperature, fruit ripening stage, agronomic management conditions, and weather [80].…”

The soursop fruit (Annona muricata L.) is a crop of significant economic value for Nayarit, which is characterized by having a bittersweet taste, making it attractive to the consumer. However, the soursop has rapid maturation which causes a short shelf life. Several postharvest management techniques have been applied to reduce its metabolic processes, such as refrigeration, use of 1-methylcyclopropene (1-MCP), and controlled and modified atmospheres. In recent years, polysaccharide-based coatings have been applied to fruits. Therefore, the objective of this investigation was to evaluate the physicochemical and biochemical changes, as well as the antioxidant activity of soursop fruits with a mucilage-based coating (2%), stored at 22°C and 15°C with a 90% RH. Weight loss, firmness, color, soluble solids, acidity, pH, phenols, flavonoids, vitamin C, and antioxidant activity were evaluated. The results obtained in the coated fruits stored at 15°C showed lower weight loss (6.4%), lower firmness (29.7 N), higher TSS concentration (10.4°Bx), and lower acidity (0.38%) compared with the uncoated fruits. The total phenolic content decreased in coated fruits stored at 22°C (54.3 mg EGA/100 g FW). The highest antioxidant activity (DPPH method) was recorded in fruits coated and stored at 15°C with an average value of 257.9 mg EAA/100 g FW. Moreover, a high concentration of vitamin C was observed in fruits coated and stored at 15°C and 22°C (20.5 and 17.5 mg EAA/100 g FW), concluding that the coating based on roselle mucilage (2%) in combination with a temperature of 15°C prevents weight loss, decreases titratable acidity, and increases the content of phenols and vitamin C. Furthermore, an increase in the shelf life up to eight days and in the antioxidant activity at the maturity of consumption was observed in the fruits coated with 2% roselle mucilage stored at 15°C.

“…As frutas de dimensões e pesagem uniformizadas apresentam mínimas perdas e manufaturação acelerada. A comercialização das frutas tem-se ampliado essencialmente em virtude da sua importância nutritiva e finalidades terapêuticas, englobando diversidades de fitoquímicos, muitos dos quais apresentam características antioxidantes, conseguindo retardar o envelhecimento e prevenir inúmeras doenças, como o câncer, doençascrônicas inflamatórias, doenças cardíacas e pulmonares (BATISTA et al, 2018).…”

“…Os antioxidantes encontram-se no consumo de compostos provenientes da dieta, como vitaminas, compostos fenólicos e carotenoides, que trabalham mutuamente com os radicais livres antes que estes controlem a reação com as moléculas biológicas, isto é, evitando as reações em cadeia ou prevenindo a ativação do oxigênio a produtos altamente reativos (BATISTA et al, 2018). A vitamina C é um dos principais antioxidantes encontrado nos sucos de frutas in natura.…”

Avaliação biométrica e análise da vitamina C em frutas exóticas comercializadas em supermercados e mercados de Teresina – PI

et al. 2020

A comercialização de frutas exóticas no Brasil vem expandindo-se bastante nos últimos anos, apresentando produção de aproximadamente 40 milhões de toneladas, mantendo-se atrás, apenas da China e da Índia. Conhecer a variabilidade em termos biométricos das frutas é de grande importância, pois cada fruta possui suas características, ainda que faça parte dos mesmos grupos de espécies. O objetivo deste estudo foi avaliar os aspectos físico-químicos e o perfil biométrico em frutas exóticas comercializadas em mercados e supermercados na cidade de Teresina-PI. Para a análise deste trabalho foram selecionadas e adquiridas 18 amostras de frutas exóticas em mercados e supermercados nas regiões das zonas norte, leste e sul da cidade de Teresina-PI tais como: ameixa, ata, atemoya, bacuri, cajarana, carambola, caqui, jiló, kiwi, morango, pequi, pêssego, pitanga, pitaya, pitomba, sapoti, seriguela e umbu. Com relação ao perfil biométrico, as frutas pitaya, carambola, jiló, bacuri, atemoya e ata, sofreram variações em relação às dimensões de tamanho. Acompanhando a porcentagem de rendimento de polpa in natura, a ameixa apresentou o maior rendimento com 97,87%. Quanto ao teor de vitamina C, a pitanga mostrou-se com o maior valor, apresentando 174,34 mg/100g. Na análise de pH, a seriguela mostrou-se como a fruta mais ácida, com valor de 1,89. Sendo assim, foi possível verificar que, cada fruta exótica, possui sua variedade físico-química e biométrica. Além disso, a perda de vitamina C está atribuída a alguns fatores externos e a quantidade elevada da mesma está relacionada ao elevado estado de maturação da fruta.
