Avaliação química e sensorial de blends de Coffea canephora Pierre e Coffea arabica L.

Abstract

The coffee blend of C. arabica and C. canephora species, made by roasting with the strategy of uniting the sensory characteristics of these prominent coffee are called blends. Considering the diversity of coffees that can be obtained, depending on the type of processing, in the preparation of the blends is important to consider the correct proportion of coffee to ensure both the quality of the final product. The objective of the present work is to analyze blends in different proportions of the species C. canephora and C. arabica, by sensory and chemical evaluations. Data were subjected to analysis of variance and regression analysis later. Significant differences were detected for all variables chemical analysis and sensory attributes of blends with higher proportions of coffee canephora, observing the change in attributes fragrance, aroma and acidity and changes in attributes bitterness and body.
