Resumo: O objetivo do presente estudo foi avaliar o uso de grãos de milho em diferentes formas (grãos secos, silagem de grãos úmidos, grãos hidratados e ensilados) na dieta de cordeiros confinados, e seus possíveis efeitos sobre a qualidade da carcaça, compreendendo avaliações quantitativas e qualitativas. Vinte cordeiros machos cruza Bergamácia x Corriedade foram utilizados. Os animais foram confinados, distribuídos em cinco tratamentos, que consistiram de diferentes relações grãos de milho secos:silagem de grãos úmidos ou de milho hidratado (0:100, 50:50, 100:0). Não houve efeito dos tratamentos sobre as características de carcaça. O rendimento verdadeiro médio de carcaça foi de 51,5% e o rendimento de carcaça comercial, de 42,4%. Não foram observadas diferenças entre as variáveis condição corporal e conformação da carcaça, em função dos tratamentos. As variáveis cobertura de gordura, cor da gordura e espessura de gordura foram semelhantes. As formas dos grãos de milho utilizados na alimentação dos cordeiros não causaram efeitos sobre a carcaça, considerando-se as variáveis quantitativas e qualitativas.

Abstract: The objective of this study was to evaluate the use of corn grains in different forms (corn dry grain, high moisture corn silage, moisturized corn silage) in the diet of confined lambs, and its possible effects on the qualitative and quantitative characteristics of the carcass. Twenty male Bergamacia x Corriedade lambs were used. The animals were confined and fed ad libitum, assigned to five treatments consisted of dry corn: high moisture corn silage or moisturized corn silage (0:100, 50:50, 100:0). There was not effect of the treatments on the main carcass characteristics. The average true yield of carcass was 51.5%, while the yield of commercial carcass was 42.4%. Differences were not observed between the variable body condition and conformation of the carcass, in function of the treatments. The variables fat covering, fat color and fat thickness were similar. The forms of the corn grains used in the feeding of the lambs did not affect the qualitative and quantitative characteristics of the carcass.

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 o f 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.
