Caracteriza??o tecnológica de jabuticabas 'Sabará' provenientes de diferentes regi?es de cultivo

摘要

The physical and chemical characteristics of 'sabara' jaboticaba from 10 differents regions of cultivation in S?o Paulo state were determined from August to September 2001 to evaluated its quality. The average fruit weight varied from 3.56 to 7.40g and it was the highest in jaboticaba fruits harvested in orchard from Casa Branca region. The average sharp index and diameter oscillated from 0.962 to 0.990 and 2.45 to 1.73 cm, respectively. The fruit firmness varied from firm to soft, and the fruits harvested in orchard situated in the Casa Branca, Pedregulho and Miguelopolis region, presented the greatest fruit firmness, suggesting a better potential for postharvest conservation. The oBrix ranged from 11.6 to 17.9 and the pH from 2.91 to 3.70 being the highest in jaboticaba fruits harvested in Guaira and Ituverava region. The titrable acidity, expressed as g of citric acid per 100g ranged from 0.888 to 1.625, the vitamina C and soluble carbohydrate content ranged from 14.86 to 24.67 mg of ascorbic acid per 100g and from 0.91 to 11.39g of glicose per 100g respectively. The results permitted to conclude that jaboticaba fruits from orchard situated in Casa Branca region presented the greatest quality, thus being more suitable for industrialization as to consumption as fresh fruit and the better postharvest conservation potential.
