Abstract
The present study aimed to evaluate productive characteristics and the physical, chemical and sensory quality of juices elaborated from different genotypes of the ‘Bordô’ cv. produced in the Vale do Rio Peixe-SC region, in 2016/17. The 11 clones evaluated were identified as: G03, G07, G08, G10, G12, G13, G15, G16, G17, G18 and G19. At harvest, fruit production and quality were evaluated. The mean productivity of the 11 tested genotypes was 31.2 t ha-1, with a production of 18.7 kg/plant. Genotypes G13, G16, G19 and G08 showed higher productivity in t ha-1 and kg/plant. G10 had the highest acidity. Genotypes G18 and G19 showed lower color intensity and phenolic compounds. Sensorially, genotypes G19 and G16 received lower scores for color, pleasant aroma and overall impression aspects. The 11 ‘Bordô’ genotypes evaluated showed high productivity and favorable physical, chemical and sensory characteristics for the industrialization of juices in the Vale do Rio do Peixe-SC region, with the exception of the juices of genotypes G18 and G19, which showed little color, something that may end up mischaracterizing the 'Bordô' juices.
Highlights
The production and commercialization of grape juices in Brazil has grown exponentially in recent years
The state lacks the production of American and hybrid grapes, mainly of the ‘Bordô’ cultivar, which attributes color, structure and flavor, characteristic to wines and juices is appreciated by the consumer
In the 2018 harvest, 26.1% of the grape processed in the state of Santa Catarina came from Rio Grande do Sul and Paraná states (Caliari, 2019)
Summary
The production and commercialization of grape juices in Brazil has grown exponentially in recent years. Statistical data from the state of Rio Grande do Sul, the largest grape producer and processor in the country, show an increase in the destination of common and hybrid grapes for juice production (Mello, 2018). In the state of Santa Catarina there was an increase in the production of grape juice in recent years, to the detriment of the production of table wines (Caliari, 2019). In the 2018 harvest, 26.1% of the grape processed in the state of Santa Catarina came from Rio Grande do Sul and Paraná states (Caliari, 2019)
