Although it is recognized that the post-harvest system is most responsible for the loss of soybean quality,the real impact of this loss is still unknown.Brazilian regulation allows 15％and 30％of broken soybean for group I and group Ⅱ(quality groups),respectively.However,the industry is not informed about the loss in the quality pa-rameters of soybeans and its impacts during long-term storage.Therefore,the objective was to evaluate the effect of the breakage kernel percentage of soybean stored for 12 months.Content of 15％of breakage kernels did not affect soybean quality.However,content of 30％of breakage kernels affected significantly soybean quality,which was evidenced by the increase of up to 75％in moldy soybeans,72％in acidity,50％in leached solids,27％in electrical conductivity,and the decrease of up to 12％in soluble protein,6.4％in germination and 3.5％in thousand kernel weight after 8 months of storage.Although the legislation establishes a percentage limit,it is recommended to store soybeans with up to 15％breakage kernels.On the contrary,values higher than that can cause a significant reduction in soybean quality,resulting in commercial losses.
