Commercial milling of suni bug (Eurygaster spp.) damaged wheat.
In some wheat growing countries, considerable quantities of commercial wheat are rendered unusable in standard milling because of pre-harvest damage of the grain by protease-injecting insects. The possibility of mitigating the detrimental effects of bug damage by eliminating the mill streams of lower quality from straight run flour was investigated. The changes in the amount of damaged kernels by cleaning and washing prior to milling were also examined. Dry cleaning decreased the level of insect damage from 26.4% to 23.0%. A further improvement to 12.8% was obtained by removing the light-density bug-damaged kernels by washing. There were substantial differences among the mill streams of the commercial mill as evaluated by the standard and modified sedimentation tests and standard alveograph test. The best streams were those from the first, second, third and fourth reductions.
