Resumo: | Pera-do-cerrado (Eugenia klotzschiana O. Berg) has a good appearance and adequate post-harvest shelf life. However, little information is available regarding its maturity stages. This study aimed at characterizing E. klotzschiana fruits harvested at three maturity stages (immature, physiological mature and ripe), in addition to evaluating the physical and chemical changes during storage at ambient temperature (24 ± 2 ºC and 75 % ± 5 % of RH) for up to 5 days. The ripe fruits had a higher fresh mass (98.03 g), width (5.61 cm) and ratio (5.37), and lower titratable acidity (1.27 %). In contrast, immature fruits showed a greener peel (101.32 ºh) and higher vitamin C content (11.23 mg 100 g-1). There was an increase in the fresh weight loss (3.05 %) and a decrease in the peel luminosity (67.09-57.12 L*) and vitamin C content (8.11-5.04 mg 100 g-1). However, the soluble solids (SS) values did not change during the 5 days of storage. A reduction in the titratable acidity (TA; 1.29-1.06 %) was also observed, which resulted in a higher ratio (3.81-5.84). In conclusion, E. klotzschiana fruits should be harvested ripe, as they present larger dimensions, better color, higher SS/TA (flavor) and are less acidic.

No entanto, existem poucas informações sobre seus estádios de maturação. Objetivou-se caracterizar frutos de pera-do-cerrado colhidos em três estádios de maturação (imaturo, fisiológico maduro e maduro), além de avaliar as alterações físicas e químicas durante o armazenamento à temperatura ambiente (24 ± 2 ºC e 75 % ± 5 % de UR), por até 5 dias. Os frutos maduros apresentaram maior massa fresca (98,03 g), largura (5,61 cm) e proporção (5,37) e menor acidez titulável (1,27 %). Em contraste, frutas imaturas apresentaram epiderme mais verde (101,32 ºh) e maior teor de vitamina C (11,23 mg 100 g-1). Houve aumento na perda de massa fresca (3,05 %), redução de luminosidade da epiderme (67,09-57,12 L*) e teor de vitamina C (8,11-5,04 mg 100 g-1). No entanto, os valores de sólidos solúveis (SS) não se alteraram durante os 5 dias de armazenamento. Também foi observada redução da acidez titulável (AT; 1,29-1,06 %), o que resultou em maior proporção (3,81-5,84). Em conclusão, frutos de pera-do-cerrado devem ser colhidos maduros, por apresentarem maiores dimensões, melhor cor, maior SS/AT (sabor) e serem menos ácidos.
