“…Musser et al (2004), avaliando as características físico-químicas dos primeiros 12 genótipos do Banco Ativo de Germoplasma da UFRPE, relataram que a variação média do teor de ácido ascórbico foi de 1067 a 1846 mg.100 g -1 de polpa. Segundo Nogueira et al (2002), acerolas maduras, provenientes do pomar comercial Acerolândia em Paudalho -PE, apresentaram teores de ácido ascórbico de 865,80 a 1797,80 mg.100 mL -1 de suco. Enquanto, Mezadri et al (2008) Os Genótipos analisados apresentaram a razão SST/ATT entre 3,79 (PL38) e 7,06 (PL34), com diferença significativa entre elas.…”

“…Vários pesquisadores têm encontrado teores de SST para acerolas maduras, variando de 5,7 a 6,5 ºBrix (BRUNINI et al, 2004); 7,47 a 8,73 ºBrix (MUSSER et al, 2004); 7,0 a 7,5 ºBrix (NOGUEIRA et al, 2002) e 4,7 a 9,2 ºBrix (GONZAGA NETO; MATTUZ; SANTOS, 1999). Segundo Alves (1996), os valores de SST, para acerolas do nordeste, podem variar de 5 até um máximo de 12 °Brix, sendo a média em torno de 7 a 8 ºBrix.…”

“…It is important to mention that the fruits used in this study were collected at a full maturity stage, and according to some studies, vitamin C can decrease during the ripening of fruits (NOGUEIRA et al, 2002;BRUNINI et al, 2004). According to Vendramini and Trugo (2000), the content of ascorbic acid unripe fruit is much lower than in red fruit with a loss of 50% by biochemical oxidation.…”

Fruits are important sources of nutrients in human diet, and Barbados Cherry (Malpighia glabra L.) is of particular interest due to its high content of antioxidants. Diets rich in fruits and vegetables protect individuals against diseases and cancer, but excessive intake of vitamins may act as pro-oxidant and generate changes in DNA. To evaluate the effect of different in natura (BAN) and frozen (BAF) Barbados Cherry pulp concentrations and synthetic vitamin C in liquid form (VC) on the chromosome level and the cell cycle division, root meristeme cells of Allium cepa L. and bone marrow cells of Wistar rats Rattus norvegicus, were used as test system. In Allium cepa L., BAN, at the highest concentration (0.4 mg.mL-1) and BAF, at the lowest concentration (0.2 mg.mL-1), inhibited cell division, and there was recovery of cell division after the recovery period in water only for BAN. In the Wistar rats, all treatments with Barbados Cherry, either acute or subchronic, were not cytotoxic or mutagenic; only the highest concentration of VC increased significantly the rate of chromosomal abnormalities. The data obtained are important to reinforce the use of Barbados Cherry fruit in the diet.

“…In Brazil, the research has been directed towards releasing new varieties, among which can be mentioned: Sertaneja [3], Olivier [4], UEL3-Dominga, UEL4-Lígia and UEL5-Natália [5]; UFRPE-7 and UFRPE-8 [6]. Nevertheless, vitamin C content depends on plant genetics, the maturity stage of fruits, harvest season, cultural methods adopted and other factors such as temperature, precipitation and insolation [7].…”

Preliminary selection of acerola genotypes in Brazil.Abstract --Introduction. Breeding studies for acerola (Malpighia glabra) improvement aim at obtaining plants that produce fruits with uniform chemical and physical attributes, including high levels of vitamin C, which can provision the market with fresh fruit and frozen pulp. High variability in fruit quality is observed in Brazilian acerola crops, especially those propagated by seeds. In this context, the objective of our research was to evaluate the physical and chemical characteristics of Brazilian acerola genotype fruits. Materials and methods. Sixteen acerola genotypes were studied in Jaboticabal, São Paulo State, Brazil. A completely randomized design with sixteen treatments and six replications was adopted. Each treatment was represented by one genotype. Several parameters related to fruit quality, such as width, length, weight, pulp percentage, soluble solids (SS), titratable acidity (TA), [SS / TA] ratio and vitamin C content, were evaluated in fruits of the acerola genotypes. The results were submitted to variance analyses, the Tukey test and cluster analysis. Results and discussion. There was a statistical difference between the acerola genotypes studied. Three of them stood out as natural sources of vitamin C. In spite of fruit size, two acerola genotypes were found to have potential for fresh fruit production. In a general form, genotypes that presented a high [SS / TA] ratio had low vitamin C content. Conclusion. The acerola genotypes studied in Jaboticabal presented high variability, forming eleven groups in relation to fruit quality parameters.
