Resumo

The objective of this work was to evaluate, throughout the storage, the effect of temperature and moisture content on soybean grains with high damage caused by stink bug in the crop, through sanitary quality. Two moisture contents (11.75 and 13.84% wet base) were used and the grains were packed in high density polyethylene packages (HDPE), stored in four BOD’s, regulated at temperatures of 20, 25, 30 and 35 °C and evaluated every two months by analyzing the water activity, grain sanity and the occurrence index. The experiment was set up in a completely randomized design and in a 2 x 4 x 4 factorial scheme, with two moisture contents, four storage temperatures and four evaluation times. The moisture content and the temperatures throughout the storage influence the sanitary quality of the soybean grains damaged by stink bug. The higher the moisture content and the storage temperature, the higher the water activity of soybeans damaged by bedbug, and the increase in the occurrence of fungi
