Resumo: | The objective of this study was to evaluate the chemical quality of maize grains, which were subjected to intermittent drying at different air temperatures and stored for nine months. The grains were harvested at 17.9% moisture, tillage of the Experimental Station of the Universidade Federal do Rio Grande do Sul (UFRGS), and dried to moisture content of approximately 13% using flash dryer with use of LPG in air temperatures of 60, 70 and 80o C. Physical analysis of moisture and chemical Crude protein, lipid, ash, carbohydrate and oil acidity, Department of Animal Science, Faculty of Agronomy, UFRGS, from sampling performed after drying, and every three months for up to nine months of storage. The intermittent drying air temperatures up to 80°C did not cause quality of corn grains immediate damage. The quality losses were greater after six months of storage. Dried grains with temperatures of 80°C had the lowest quality loss during the nine months of storage. The lipid content was the chemical constituent that deteriorated most during storage. The longer the drying time is, the higher the latent damage in the chemical quality of maize grain during storage. The higher the grain moisture during storage, the greater the loss of quality of grain. |

Os grãos foram colhidos com umidade de 17,9%, oriundos de lavoura da Estação Experimental da Universidade Federal do Rio Grande do Sul (UFRGS), e secos até umidade de aproximadamente 13%, utilizando secador intermitente com uso de GLP nas temperaturas do ar de 60, 70 e 80oC. Foram realizadas análise física de umidade e químicas de proteína bruta, lipídeos, cinzas, carboidratos e acidez do óleo, no Departamento de Zootecnia da Faculdade de Agronomia da UFRGS, provenientes de amostragem realizada após a secagem, e a cada três meses por até nove meses de estocagem. A secagem intermitente em temperaturas do ar de até 80oC não causa danos imediatos qualitativos aos grãos de milho. As perdas de qualidade foram maiores após seis meses de armazenamento. Os grãos secados com temperatura de 80oC apresentou as menores perdas qualitativas durante os nove meses de armazenamento. O teor de lipídeos foi o constituinte químico que mais se degradou durante o armazenamento. Quanto maior o tempo de secagem, maior é o dano latente na qualidade química dos grãos de milho durante o armazenamento. Quanto maior a umidade dos grãos durante o armazenamento, maiores são as perdas de qualidade desses grãos.Departamento de Diagnóstico e Pesquisa Agropecuária.
