Quality of shaded and unshaded coffee, in post-harvest management in Southwestern Bahia

Abstract

This study was developed to characterize aspects related to the physical and chemical quality of Arabica coffee grown under shading and full sun with wet and dry post-harvest management. The experimental design was a randomized block in factorial 2 x 2 (two forms of farming - full sun and wooded with grevillea and processing two forms - dry and wet), consisting of five blocks, totaling 20 plots. Plots were, after collection and manegement post-harvest by volume of 10 liters of the fruit according to treatment. At harvest, for each form of cultivation, the was evaluated, wet mass, drought mass and moisture content of 100 fruits. Was determined after drying the dry mass coffee and mass of coffee. To determine the quality of coffee was analyzed for physical and chemical properties. There was a significant interaction between postharvest manegement and characteristics of the coffee plantations in wet weight and dry weight of coffee, coffee yields and total titratable acidity. The wet processing increases the yield of the fruit and the mass of coffee. Coffee wooded have fewer defects, higher percentage of coffee retained in the sieve 17 above and a higher concentration of non-reducing sugars and total sugars. The association of coffee trees to contribute to improved physical and chemical aspects of the grains. The use of wet postharvest management, improves the physical quality of the coffee.
