During coffee drying, different temperatures applied to the beans with varied humidity content levels can interfere in the membranes integrity, germination, organic acid and carbohydrate content resulting in coffees with distinct flavors. The quality control of the beans will be much more effective the earlier the alterations provoked in the postharvest are detected. This work has an objective to study alternative methods for the dehydration of the coffee beans using ultra-drying followed by slow drying and its impact on the sensorial quality, chemical composition and physiology. For that purpose, coffee lots were processed by the methods, dry (natural coffee) and wet (fully washed coffee); and sun-dried and machine-dried at a constant 60°C temperature and alternating 60/40°C. The sensory quality of the samples was assessed by the Specialty Coffee Association of America (SCAA) analysis protocol. The sugar, total titratable acidity and the phenolic compound content was also analyzed. The physiological alterations of the coffee beans were analyzed by germination tests, emergence speed index, electrical conductivity and potassium leaching. The temperature of the drying air significantly altered the sensorial quality of the coffee beans. The processing way associated to drying methods causes many physiological alterations with the highest damage observed in the natural coffees. For the first time, we are showing that drying with heated air at 60/40ºC is promising for the fully washed coffee beans, which are more tolerant to dehydration than the natural coffee beans. Conversely, the natural coffee beans were much more sensitive to drying regardless the temperature, with very low performance in the physiological analyses. The drying at the constant 60ºC temperature is inappropriate for the natural coffee as well as for the fully washed coffee beans. In addition, the physiological tests used were shown effective for the early evaluation of coffee beans quality.

The present study aimed to evaluate the use of organic and inorganic minerals in Cobb500 broiler breeder diet and its effects on the performance. The birds were housed in an experimental house at Poultry Laboratory of the Federal University of Santa Maria with 20 fl oor pens of 4.61m2 each. The experiment was conducted between 51st and 65 th weeks of age of birds. The design was completely randomized with four treatments and fi ve pen replicates with 22 hens and 2 roosters each. The treatments evaluated were: PI=100% mineral inorganic premix; PO= 100% mineral organic premix: PI+PO= 70% mineral inorganic premix + 30% mineral organic premix and PI+Zn= 100% mineral inorganic premix, except zinc mineral, that was 70% inorganic form and 30% organic form. The following parameters of performance and egg quality were evaluated: laying rate, body weight, egg, albumen and yolk weight, yolk color and specifi c gravity of eggs. These parameters were performed one day per week throughout the experimental period to evaluated egg quality. Under the conditions and time that the experiment was conducted, the use of organic minerals had no signifi cant effect on the performance and egg quality parameters evaluated in the broiler breeders.
