“…Antioxidant activity of extracts of araçá ( Psidium cattleianum ), butia ( Eriospatha butia ), pitanga ( Eugenia uniflora ) and blackberries ( Rubus sp; cv. Xavante and Cherokee) collected in the southern region of Brazil found total phenolic content ranging from 359.5 to 816.5 mg EAG 100 g −1 fresh weight [ 20 ]. The content of total phenolic compounds varies according to the type of resource [ 19 ].…”

Myrciaria floribunda, also known as rumberry, is a tree native to the Brazilian Atlantic Forest, where its fruits have the potential for commercial use. This study evaluates the antioxidant potential, determines the phytochemical profile, and chemically characterizes the rumberry fruit. Accessions were sampled from the Rumberry Active Germplasm Bank of the Federal University of Alagoas, Brazil. Physical characteristics, chemical characteristics, and phenolic compound content were analyzed. Chemical profile characterization was carried out using PSMS. Accessions had an average weight of 0.86 g. Accession AC137 presented a higher pulp yield (1.12 g). AC132 and AC156 had larger fruits, AC137 showed greater firmness (5.93 N), and AC160 had a higher and total phenolic content ratio (279.01 ± 11.11). Orange-colored accessions scored higher in evaluated parameters, except for AC160 for phenolic content. Thirty-two compounds were identified on positive ionization mode and 42 compounds on negative ionization mode using PSMS. Flavonoids, followed by the derivatives of benzoic acid, sugars, and phenylpropanoids, were the most prominent. Myricitrin, quercitrin, and catechin stand out as flavonoids that have been reported in previous studies with antioxidant and antimicrobial properties, in addition to health and therapeutical benefits, demonstrating the potential of the rumberry fruit.

“…The soluble solids content determines the degree of sweetness of fruits (Spoto et al, 2020) due to the higher proportion of soluble sugars in their composition (Fernandes et al, 2017). In the literature, average soluble solids levels of 7.70 and 9.60 ºBrix were reported in mature coconuts (Souza, 2016;Souza et al, 2018).…”

Quality of Butia capitata fruits harvested at different maturity stages

et al. 2022

Butia capitata (Mart.) Becc. or “coquinho azedo” is a native palm species of the Brazilian savannah, bears fruits which are sold fresh or as frozen pulp. This study examined postharvest changes in “coquinho azedo” harvested at a commercially immature stage and later evaluated the quality of these fruits by comparing them with those harvested fully ripe. Fruit purchased in the 2020 harvest in Santo Antônio do Retiro, MG (Brazil), were harvested at different degrees of maturity, namely, commercially immature and ripe, according to the point of harvest adopted in the region. For 7 d, weight loss, skin color and respiratory activity were evaluated in the commercially immature-harvested fruits. At 7 d postharvest, physical and chemical evaluations of the pulp were performed. The ripe-harvested fruits were subjected to the same evaluations, but only at 1 d postharvest. The skin color of commercially immature-harvested fruits tended to yellow over the days. Respiration postharvest increased in the immature-harvested fruits. Fresh weight loss exceeded 10% but without compromising appearance. The commercially immature-harvested fruits had 55% more total phenols, whereas the ripe-harvested fruits had higher soluble solids and ascorbic acid contents. Pulp color, soluble solids/titratable acidity ratio and total carotenoid contents were similar regardless of the degree of maturity at harvest. During the days after the harvest of the commercially immature “coquinho azedo”, changes take place which cause them to resemble the fruit harvested ripe. Based on the evaluated traits, the early harvest did not compromise the ripening of the fruits.

“…Classifica-se como uma baga obovoide, amarela ou avermelhada, piriforme, coroada pelo cálice e com período de amadurecimento entre setembro e março (LOPES; SILVA, 2018). Sua composição é fonte de compostos fenólicas, vitamina C e ácidos graxos insaturados (SOUZA et al, 2018;MEREGALLI et al, 2020), conferindo ao fruto uma potencial atividade antioxidante e funcional (LOPES; SILVA, 2018).…”

O estudo da estabilidade de novos produtos oriundos do processamento de frutas nativas subutilizadas é essencial para o desenvolvimento da indústria nacional. O objetivo foi avaliar o efeito de diferentes embalagens sobre a estabilidade físico-química de doce em massa de araçá amarelo adoçado com xilitol. A polpa de araçá foi avaliada quanto aos parâmetros físico-químicos de qualidade e seguiu para o processamento do doce. O doce foi elaborado com 60% de polpa, 40% de xilitol, 2% de pectina de Baixo Teor de Metoxilação e 0,12% de cloreto de cálcio, sendo acondicionado em quatro tipos de embalagens (polipropileno, vidro, filme PVC e filme PVC recoberto com alumínio). A estabilidade do doce foi avaliada, durante 90 dias de armazenamento a temperatura ambiente (27,5 ºC), sendo realizadas as análises de qualidade a cada 30 dias. O teor de água e sólidos totais do doce diferiram significativamente entre os tipos de embalagens para os tempos de 30, 60 e 90 dias. Assim, a migração da água para o ambiente ocorreu mais facilmente nos doces embalados em polipropileno, filme PVC recoberto com alumínio e filme PVC, devido as características físicas da matriz polimérica das embalagens plásticas. Para o pH, entre 30 e 90 dias de armazenamento apenas a embalagem de filme PVC recoberto com alumínio não apresentou-se estável. Infere-se que o doce em massa de araçá é um produto inovador, e que o armazenamento a temperatura ambiente em embalagem de vidro transparente com tampa metálica até 90 dias é o mais viável.
