Fruiting and quality attributes of cambui (Myrciaria floribunda (West ex Willd.) O. Berg in the Atlantic Forest of northeast Brazil

Abstract

Cambuizeiro is a fruit native to the Atlantic Forest biome that has potential for ornamental use and for human consumption, either raw or processed, due to the organoleptic characteristics of its fruits. Accordingly, the study objective was to evaluate the fruiting periods and quality attributes of two types of cambuizeiros, differentiated by fruit color. The plants studied were from a natural population from the Embrapa Tabuleiros Costeiros Experimental Station, in the municipality of Itaporanga d’Ajuda, state of Sergipe, Brazil. A total of 20 plants, 14 with orange and six with purple fruit, seven days after anthesis (DAA), were evaluated weekly during fruiting. After harvest, the fruits were evaluated for weight, length, width, number of seeds, pH, soluble solids (SS), total titratable acidity (TTA) and vitamin C content. There was heterogeneity in the ripening of the two cambuizeiro types. The highest peak of ripening occurred at 63 DAA (83.2% of orange and 68.3% of purple fruits). The purple fruits had superior physical attributes. However, the pulp of the orange colored fruits had a higher TTA content. Both types of fruits have potential characteristics for commercial exploration and use.

Chemical Physical Characterization and Profile of Fruit Volatile Compounds from Different Accesses of Myrciaria floribunda (H. West Ex Wild.) O. Berg through Polyacrylate Fiber

“…Rumberry fruits had a pH from 3.35 to 3.99, with an average value of 3.74, with no significant difference between the accesses studied (Table 1). These values were similar to those reported in fruits of the same species [1], whereas in fruits of the same genus, a pH of 2.41 was reported [18].…”

“…The fruits of accesses AC67, AC92, and AC160 showed the lowest values in terms of fruit weight, pulp weight, and a number of seeds. The study by Rodrigues et al [14] obtained an average for the weight of the fruit (2.87 g), pulp weight (1.29 g), and seed weight (0.49 g) higher than those reported in the present study, while the number of seeds remained equal, containing one to two seeds per fruit [1].…”

“…The accesses AC132 (11.64 mm of DL and 10.43 mm of DT) and AC156 (10.66 mm of DL and 11.50 mm of DT) presented the largest dimensions and the highest pulp yields (0.64 and 0.69 g, respectively). The fruits had a medium diameter (longitudinal and transversal) greater than those reported in red jambo (Syzygium malaccensis) [16] fruits and inferior to those reported for rumberry fruits (Myrciaria floribunda), in their orange and purple color-4.09 to 4.47 mm and 4.47 to 4.87, respectively [1].…”

“…O. Berg is a species belonging to the Myrtaceae family, from which the fruits are popularly known as 'camboim,' 'jabuticabinha,' 'myrtle,' 'duke,' 'goiabarana,' 'araçazeiro,' 'cambuí,' and 'rumberry.' In Brazil, this species can be found mainly in the Atlantic Forest biome, easily observed in the Northeast of the country, specifically in the states of Sergipe and Alagoas [1].…”

Physicochemical Characterization and Paper Spray Mass Spectrometry Analysis of Myrciaria Floribunda (H. West ex Willd.) O. Berg Accessions

“…The rumberry tree is a fruit tree that grows naturally in a wide range of environments, distributed throughout Northeast and Northern South America and Central America. In Brazil, this species can be found in the Atlantic Forest biome in the Northeastern region, more abundantly in the states of Alagoas and Sergipe [3]. The Rumbery's trees are shrub or tree that has potential for ornamental use.…”
