2. CLASSIFICATION OF ROBUSTA COFFEE FRUITS AT DIFFERENT MATURATION STAGES USING COLORIMETRIC CHARACTERISTICS
ABSTRACT Coffee growers who produce the robusta species (Conilon) have sought to increase productivity and drink quality by improving production techniques. Artificial vision systems can assist in increasing the efficiency of operations associated with crop management. This study aimed to obtain colorimetric characteristics of robusta coffee fruits at differ

3. INFLUENCE OF DIFFERENT TEMPERATURES AND AIRFLOWS ON DRYING OF NATURAL AND PULPED COFFEE
ABSTRACT This study aimed to evaluate drying kinetics for natural and pulped coffee, using different temperatures and drying airflows. For the conduction of the experiment, coffee fruits (Coffea arabica L. cv. Topázio) were harvested manually, selecting only ripe fruits and subsequent to the hydraulic separation. For drying the coffee, use a mechanical drye

4. MATHEMATICAL MODELLING AND IMMEDIATE AND LATENT QUALITY OF NATURAL IMMATURE COFFEE UNDER DIFFERENT DRYING CONDITIONS
ABSTRACT This work aimed to study the immediate and latent effects of different relative humidities on the quality of dried coffee fruits, describe the drying kinetics of natural immature coffee (Coffea arabica L.), and evaluate the mathematical model that best fits the experimental drying data. The drying was carried out in a fixed layer dryer coupled to a

5. Concentration and accumulation of micronutrients in robust coffee
ABSTRACT. Knowledge on the dynamics of micronutrients in coffee tree assists nutritional diagnosis and fertilization management. Therefore, the objective of this study was to evaluate the concentration and accumulation of micronutrients in the leaves and fruits of Coffea canephora. The experiment was managed in crops propagated for 2.5 years in a split-plot-

8. Scale insects (Hemiptera: Coccoidea) associated with arabica coffee and geographical distribution in the neotropical region
ABSTRACT Coffee is one of the most important Brazilian agricultural commodities exported, and Minas Gerais and Espírito Santo States are the main coffee producers. Scale insects are important coffee pests, and 73 species of Cerococcidae (3), Coccidae (18), Diaspididae (6), Eriococcidae (1), Ortheziidae (3), Pseudococcidae (21), Putoidae (2) and Rhizoecidae

9. Physiological and ultrastructural analysis reveal the absence of a defined abscission zone in coffee fruits
ABSTRACT In order to investigate the existence of a possible abscission zone in the binding region between the peduncle and the coffee fruit, as well as the biochemical events involved in fruit ripening, we studied peduncles and fruits of Coffea arabica L. cv. “Icatu amarelo”. Coffee fruits were harvested at different maturation stages by using specific

10. Influence of air temperature on proteinase activity and beverage quality in Coffea arabica
Fruits were collected from trees of Coffea arabica cv. Obatã grown at Mococa and Adamantina in São Paulo State, Brazil, which are regions with marked differences in air temperature that produce coffee with distinct qualities. Mococa is a cooler location that produces high-quality coffee, whereas coffee from Adamantina is of lower quality. The amino acid an

11. Sistemas alagados construídos para tratamento de águas residuárias do processamento dos frutos do cafeeiro: eficiência e caracterização das comunidades microbianas / Constructed wetlands systems for wastewater treatment in the processing of coffee fruits: eficiency and characterization of microbial communities
This study aimed to evaluate the influence of ryegrass cultivation (Lolium multiflorum Lam) and the artificial aeration of the affluent in the removal of organic matter, nutrients and phenolic compounds present in the ARC, as well as the diversity of microbial communities attached to the medium (gravel) and the rhizosphere of ryegrass, using T-RFLP multiplex

12. Caracterização in silico e análise da expressão de genes das rotas de biossíntese e sinalização do etileno em frutos de diferentes cultivares de café (coffea arabica) / In silico characterization and expression analysis of genes of the ethylene biosynthesis and signaling pathways in fruits of different coffee (Coffea arabica) cultivars
Coffee is the second most commercialized product in the world posing as an important source of income and jobs in several countries, mainly in developing countries such as Brazil, the largest producer and the second largest consumer of coffee in the world. Coffee quality, among other factors, is directly associated to the fruit ripening stage at harvest time
